What Micron Filter For Well Water

How to Select a Filter Cartridge for Whole House Sediment Removal

Filters made of cartridges offer the advantages of being inexpensive, simple to install, requiring no energy, and generating no waste water. The downsides of cartridge filters, on the other hand, are that silt may ultimately clog the pores of the Water Filter Cartridge membrane, causing pressure drop and, as a consequence, a loss of water pressure in the house or company. Cartridge filters, on the other hand, are simple to replace and, in the case of certain pleated cartridges, are simple to clean and re-use after they have been cleaned.

Cartridge filters are frequently fitted in series, with the first cartridge filter being a bigger micron-rated cartridge filter, followed by smaller micron-rated cartridge filters, all the way down to 1 micron.

Surface Filter (Pleated) Cartridges

Surface filters are used to filter water and other liquids just on the surface of the filter membrane. Sheets of polypropylene, nylon, or Teflon, among other materials, are pleated and connected at the ends to provide a large filtering surface area. Upon contact with the sheet’s surface, the impurities are trapped, producing a layer that will eventually help in the filtration process. As the pressure drop grows, the filter cartridge can be removed from the filter housing and flushed down the drain at some time throughout the process.

However, while pleated filters are commonly employed as coarse pre-filters, with pore sizes typically ranging from 30 to 500 microns, they are also capable of being utilized in sub-micron applications.

Filtration ratings for pleated surface filter cartridges can range from 50 microns down to 0.04 microns absolute, and they are commonly employed in semiconductor water filtration or pharmaceutical water filtration applications.

Filtration areas can be as large as 11 square feet in a standard 10′′ by 2.5′′ cartridge, and much more than that.

Depth Filter Cartridges

Housing for the Big Blue Filter Cartridge Depth filters are typically found in the form of wrapped string, spun, or “melt-blown” cartridges that trap particles of greater size on the surface and tiny particles under the surface all the way down to the core of the filter. They perform best when a wide range of particle sizes are being filtered through them. Depth filters remove more silt and hold more sediment in general than a surface filter cartridge, and they do so without compromising pressure.

How Small is A Micron?

Microns are the unit of measurement for sediment reduction in filter cartridges. The micron rating of a water filter reflects the filter’s capacity to remove impurities based on the size of the particles it is capable of removing. A filter with the designation “5 microns” has some capacity of catching particles as fine as 5 microns in size. In the case of water filters, the micron levels are generally Nominal or Absolute. The use of nominal-rated cartridges for sediment removal is more typical in this application.

This is because it becomes critical that the filter cartridgeabsolutely must be rated at 1 micron.

Nominal Micron Scale (Nominal Micron Scale) NMR typically indicates that the filter is capable of capturing a specific proportion of particles of a specified size.


Any beads that pass through the opening are caught and recorded. If you are filtering lake or creek water (often known as “surface water”) or if your well water is being influenced by surface water, you will need an AMR filter to remove parasites and cysts.

Which Type of Filter Cartridge is Best?

One advantage of whole-house filter housings is that they allow you to experiment with different water filter cartridges to see which one works best for your particular application. A pleated 50-micron filter cartridge is followed by a dual grade 25/1 micron depth filter, which is generally what we recommend. Depth filters with two grades of filtration are recommended for extremely fine sediment in the range of 1 to 5 microns. Dual grade depth filters start at 50 microns on the exterior and filter down to 5 microns on the inside, making them extremely efficient in filtering a wide variety of sediment particle sizes.

‘What is the best sediment filter for my applications?’ is one of the most often asked questions we receive at Serv-A-Pure. Unfortunately, there isn’t a straightforward solution. The style, size, and micron grade will vary depending on the application due to the fact that each circumstance is unique. Where can I get information on what type of home sediment filter to buy? In terms of sediment filters for whole-house applications, it is advised that either a 10″ or a 20″big blue type filter be installed.

  1. What should the size of my sediment filter be?
  2. It is recommended that 2.5-inch-diameter filters be used more frequently in point-of-use applications such as single faucets, toilets, or appliances.
  3. The most effective method of determining what micron rating you require for your entire home application is through trial and error.
  4. Start with a 5 or 10 micron filter to observe how it performs, and then make modifications based on that performance.
  5. The lower the micron number, the more silt the filter will capture, but the more quickly it will clog up as the micron rating increases.
  6. If you observe that silt is getting through the filter, you might experiment with a lower micron rating filter.

Consider the performance of the filter, the lifespan of the filter, and the cost when selecting the best sediment filter for your needs. Get in touch with our team of specialists for additional information on selecting the best whole home sediment water filter right now!

Which Micron Sediment Water Filter is BEST for My Family?

One of the most often asked inquiries we receive at Serv-A-Pure is, “What is the best sediment filter for my application?” Unfortunately, there isn’t a single straightforward solution. The style, size, and micron grade will fluctuate for each application due to the fact that each circumstance is unique. Where can I get information on what type of sediment filter to buy? When looking for a sediment filter for whole-house applications, it is advised that you install either a 10″ or a 20″ large blue type filter.

  • What size sediment filter should I use?
  • Because a 2.5″ diameter filter does not have the ability to handle the amount of flow necessary for whole-house sediment filtering, it is not suggested that this size filter be used for this purpose.
  • For my whole-house sediment filter, what is the appropriate micron grade to use?
  • In certain cases, a sediment filter can endure for up to 12 months or more, but in other cases, the filter will only last for three weeks or less.
  • Try using a 20-micron filter the next time your 5-micron filter becomes clogged after 3 weeks.
  • When no sediment is seen passing through your filter, you may be confident that you have the proper micron ratings.
  • A delicate balancing act goes into selecting the proper sediment filter.
  • More information on selecting the best whole home sediment water filter is available from our team of specialists.

So how do you know which one is best for your purposes?The way you choose your sediment filter is to look at the filter’s micron rating and the application you are using it for.

A micron is a millionth of a meter in length and width. And, more importantly, what does this entail in everyday terms? For example, a human hair has a diameter of 45 microns, whereas a red blood cell has a diameter of 5 microns and so on. Prior to selecting a sediment filter, you must first determine what you hope to achieve as the final result – specifically, what you plan to filter out of the solution. Consider these samples to assist you in determining what will work best for your needs.

  • A pre-filter for Ultraviolet radiation will need to be able to filter down to a very small 5 microns in order to be effective. For the purposes of eliminating some of the particles in your water that are clogging the screens running to your washing machine or bathroom faucets, a coarser 20 micron filter would suffice
  • Otherwise, a finer filter would be required. A dual gradient filter, such as a 50 to 5, is a wonderful option for getting the benefits of both filters at the same time. A 50 to 5 filter has a very coarse 50 microns on the exterior and a much finer 5 microns on the inside. Another issue to think about is whether there are any alternatives to polypropylene filter cartridges. If you have a lot of very coarse particles in your water and you’re continuously replacing filters, a spin down filter may be the best option for you to consider. However, bear in mind that the finest they may reach is around 60 microns, and you must maintain these. In the event that you have a lot of sand but don’t want to constantly manually cleaning the spin down filter, you may use an automated backwashable filter, which will remove sediment down to almost 5 microns in size. In cases when you have numerous requirements – such as coarse sand, excessive sediment, and the need to pre-filter for a UV light – you can combine a number of filters, beginning with the coarsest filter and working your way down to the finest filter. If you have a carbon filter in your system, it should be the final filter in the system since carbon can clog very easily from sediment in your water – and you want to get rid of that sediment first

Gary the Water Guy, one of our Certified Water Specialists, is enthusiastic about the water treatment business – from water softeners to reverse osmosis systems to UV filters and beyond – and is here to help you battle terrible water. Please contact ushere if you require assistance in determining the most appropriate water treatment options for you and your family. I’ll see you in your next video on Water filtration fundamentals, which you can find here.

  1. Is that a five, a ten, a fifty, or a hundred?
  2. Nevertheless, starting right now, I’ll explain everything to you, and I’ll guide you in making the greatest decision for you and your family’s needs.
  3. Gary The Water Guy (Gary The Water Guy): As you can see, the filters all have a similar appearance, don’t you think?
  4. This one is one micron in size.
  5. It has 25 microns, 50 microns, 100 microns, 2501, 5005, 7525 microns, and so on.
  6. Micron ratings are used to differentiate them, yet they are all the same size as one another.
  7. In the event that you pick one that is too coarse, it may not be able to do the task you want it to, such as pre-filtering the water for your UV disinfection system, and you may end up compromising that system.

So, what exactly is a micron?

To put it another way, what does this mean in everyday terms?

A red blood cell has a diameter of five microns.

If you’re attempting to get rid of the gray silt that’s in the water, the extremely fine material, a five-micron filter will be able to handle it.

It’s perfectly acceptable to use a 25-micron filter if all you’re trying to do is remove some dirt from the water because it’s clogging up the screen in your washing machine or something along those lines.

So you could use a 50 micron filter like this one as a first line of defense, and then a five-micron filter as a second line of defense because you still want to get the water down for the ultraviolet disinfection system, so you could use a couple of filters.

As an example, this is a 5005 number.

It gets rid of the heavy stuff, the big stuff, the logs and the frogs, as we like to call them.

This allows you to store large amounts of material outdoors while still receiving the five-micron filtration.

As a result, you should give it some thought.

You have to change filters on a regular basis, which is a real pain.

You could use a spin down filter instead.

In a nutshell, this is connected to your plumbing system.

There’s a screen inside here that filters out the water, and then the water continues on to the next location.

That’s a great filter.

Gary The Water Guy (Gary The Water Guy): Another alternative is you can go with an automatic backwashing filter like this one behind me here.

So a NextSand backwashing filter will filter down to five microns, which is pretty fine.

Gary The Water Guy (Gary The Water Guy): If you have a carbon filter as part of your water filtration system, you’d want to put that after the sediment filter.

Sediment quickly clogs that carbon filter, so you want to make sure the sediment filters first and then the carbon filter. Gary The Water Guy (Gary The Water Guy): For your next video on water filtration, click up here, and I’ll see you there.

Ultimate Guidance of Choosing Spin-down Sediment Filters

Photo courtesy of Jana Sabethon Unsplash The majority of the time, water sources get blocked and loaded with a variety of impurities that degrade the quality of the water. Using standard sediment filters, which may require filter change every month or sooner, it is difficult to remove pollutants with larger granules such as sand, grit, and other particles. Spin-down filters are in helpful in situations like these. Spin-down filters are flushable and re-usable, unlike other types of filters. A few of them are even equipped with automated flushing functions, which make system maintenance an absolute doddle!

  • A spin down filter is quite useful for cleaning up water from a well, and it is especially useful when cleaning up water from a pond.
  • Filters with cartridges ranging in size from 5 to 20 microns are used in regular sediment filters.
  • Here are some more advantages of using a spin down filter: Filter out big particles such as sand, grit, and other sediments by using microns that are greater than 100 microns.
  • Simple to maintain – certain versions have an auto flush option that makes it even easier.
  • It relieves a significant amount of labor from the following filters and is an excellent first step in a filtration system.
  • This product is compatible with copper, PEX, PVC, and CPVC pipes.
  • Each model differs in terms of features, capabilities, and micron availabilities, among other things.
  • However, it also implies that the filter is more susceptible to being clogged and that it must be flushed more frequently.
  • Additionally, you may combine two different micron size spin-down filters to extract the maximum amount of sediment from your source water.

1.WSP Series

This spin-down filter is the foundation of our design.

Micron diameters range from 50 microns to 1000 microns for its mesh screens, with a total of 5 distinct micron sizes available. The lifespan of these mesh screens is normally between one and two years before they need to be replaced.


They are the same size as the WSP series, and they are available with mesh screens ranging from 50 to 1000 microns in size. The model includes Siliphos, which is a component that prevents scaling and corrosion from occurring. Siliphos is a colorless and odorless compound that produces a thin layer of protection around the pipes’ inside surfaces. This component stops water from turning brown or red and helps to eliminate hardness scaling from the water.


The WSP-GR Series includes a head that rotates 360 degrees, making installation simple (can be installed in any direction). It also contains a double-sided scraper, which deep cleans the filter and reduces the frequency with which it needs to be serviced. Micron sizes are now available in two different sizes – 50 microns and 100 microns.


The systems in this series are equipped with an incorporated auto flushing feature, which makes them ideal for those who wish to keep their system’s maintenance to a bare minimum. On the high-definition touch screen, you can simply select auto, semi-auto, or manual to have the system flush automatically on a schedule that you specify for yourself. It is also significantly larger than the simple spin-down filter variants in the WSP-ARB Series. Because of its size, it does not require as often flushing as other toilets.


It is recommended that you choose the iSpring WSP-B series if you require a spin-down sediment filter with large capacity but do not mind cleaning it manually. This model is the same size as the WSB-ARB Series, but it does not have the auto-flushing feature, making it more cost-effective in the long run. Micron sizes are available in two different sizes: 50 microns and 100 microns. Of other cases, removing sediments from your water may just be the first step in a comprehensive whole-house water filtration system.

Testing your water by your local County Cooperative Extension office to find the optimum treatment procedure is highly recommended.

Understanding a Microns Role in Your Whole House Water Filter

It is recommended that you choose the iSpring WSP-B series if you require a spin-down sediment filter with large capacity but do not mind cleaning it yourself. Despite the fact that this model is the same size as the WSB-ARB Series, it does not have the auto-flushing technology, making it more cost effective. In terms of micron sizes, the model has two options: 50 microns and 100 microns. Of other cases, removing sediments from your water may just be the first step in a comprehensive whole-house water purification process.

How big is a MICRON?

It is a unit of measurement that represents one micrometer, which is equal to a millionth of an inch or one-millionth of a meter. It is common to use microns to describe the size of water pollutants since they are equivalent to 0.00004 inches or.0001 centimeters. A micron level refers to the smallest size of contamination that can be removed by the filter in question. Typically, the micron levels in water filtration are between.5 and 5 microns in size. For example, if the bacteria in your water are one micron in size and you have a filtration system with a micron level of one, the filtration system will be able to filter out the bacteria in your water (as well as anything larger than 1).

For comparison, a human hair may be as large as 70 microns in diameter, while a bit of home dust can be as small as 40 microns.

Any particle less than 50-60 microns in size is too tiny to be seen with the human eye, and hence cannot be detected.

In water filtration, the micron values are typically between.5 and 5 microns.” However, this is only a portion of the narrative.

Microns are important at every step of filtration

Whole-house filters often use a multi-step procedure to rid your water of pollutants of all micron sizes, such as bacteria, sediments, and silt, before returning it to the tap. Water will first go through a pre-filter procedure, which will remove bigger particles, pollutants, and toxins found in your tap water before proceeding to the main filter. Keep in mind the size of the particles that are removed at this stage — many sediment pre-filters are capable of removing particles as small as 1 micron in size, for instance.

  1. As an illustration, let’s look at our Aquasana OptimH2O® Water Filter System.
  2. A combination of catalytic and activated carbon is used in this block to accomplish ion exchange and sub-micron filtering.
  3. The method delivers first-of-its-kind efficacy in reducing lead and PFOA/PFOS levels in the environment.
  4. Chlorine and chloramines have a remarkable ability to persist in the environment and can cause skin and hair damage, as well as being a source of concern for individuals who suffer from asthma.
  5. Another example is the fact that our Rhino® whole home water filter systems include two primary storage tanks.
  6. Copper-zinc and mineral stone are stored at the top of the tank, where they are used to minimize chlorine, water-soluble heavy metals, and other contaminants.

Micron levels are critical at every stage of the manufacturing process. We would be unable to adequately remove particles that cannot be seen without the use of a microscope if we did not have this unit of measurement.


You may already be aware of this, but the lower the micron level of a filter, the greater the number of toxins it can capture and remove from your water. Remember to pay close attention to the micron level when selecting a water filter while making your purchase. The cost of a decent water filter with a low micron level will be slightly greater than the cost of a filter with a larger micron level, but it will be well worth it in the long run. If you have any more concerns concerning micron levels or our groundbreaking OptimH2O® Whole House Filter, please do not hesitate to contact us.

What Is a Micron Rating? Micron Sizes for Water Filters

When measuring the average size of the holes between pieces of filter media, the units are measured in microns. For example, the apertures of a 20-micron filter are bigger than those of a 5-micron filter. As a result, the 20-micron filter element will allow for the passage of bigger particles through the filter than the 5-micron media would permit. A 1-micron filter would effectively remove the vast majority of bacteria and cysts, which have sizes ranging from 0.2 to 2 microns in width or diameter and from 1 to 10 microns in length for the non-spherical species.

If you are using well water, however, the water has already been disinfected with chlorine, chloramines, and/or fluoride to remove bacteria.

Installation of a 1-micron absolute water filter at the point of use will remove the vast majority of bacteria (99.9 percent); however, if your water has tested positive for bacteria, it is safer to install a chlorine injection water sanitizing tank to purify the water before it enters the house, followed by a whole-house filter to remove the chlorine.

  • The flow capacity of water decreases as the micron rating decreases, especially if the water has a high concentration of sediment, which is common in well water.
  • Low micron-rated filters must be equipped with bigger components in order to avoid compromising valuable flow.
  • In a well water scenario, it is normal to find two or three sediment prefilters in the water flow, with the first filter having a higher micron rating to remove bigger particulates and the second and third filters having a lower micron rating to remove smaller particulates.
  • Using this procedure, all filters, including carbon filters, which are responsible for eliminating disinfection chemicals and byproducts, heavy metals, herbicides, pesticides, THMs, and other water contaminants, will have a longer service life.

Since a 1-micron whole house filter would clog up and need to be updated too frequently, 5-micron whole house filters are used in Whole Housemodels. Some whole home clients opt for a 1 micron prefilter, which is substantially less expensive but must be updated once or twice a month.

5 Best Sediment Filters for Well Water [Reviews 2022 ]

Nature is capable of many things, but she is incapable of providing filtered water from a well. This implies that if you do obtain your drinking water in this manner, it may include sediment as well. Sediment may be anything from fine sand to rust, and it can all have a negative impact on the flavor, the fragrance, and the appearance of your tap water. It can also cause damage to your sinks and other water-based household items. This is why it is critical to invest in a sediment filter in order to remove these particles from your water.

These are typically used in conjunction with whole-house filtration systems, where they work in conjunction with carbon and other filters to offer complete filtration.

There are several solutions available, however we hope that our evaluations will assist you in identifying the most appropriate sediment filtration system for your house.

A Quick Comparison of Our Favorites

The iSpring WSP-500sediment water filter features a 500-micron screen and is made of plastic. It is intended to be used as a component of a multi-stage filtration whole-house filter system, since it will prevent sedimentary particles from going through. It is flushable, which means that it may be re-used after it has been cleaned. Regular flushing also contributes to the WSP-500’s ability to sustain peak performance for a longer period of time. The stainless steel mesh is 500 microns in size, and the device features a brass reinforcing head for added strength.

The filter, according to the manufacturer, will last up to two years in use.

The only thing we don’t like about it is that it doesn’t filter out iron very well.


  • Good value for money
  • Housing that is transparent
  • Head made of brass for strengthening
  • Flushable and re-usable materials Two-year shelf life

2.Rusco NT100-100P Sediment T-Style Water Filter – Best Value

The Rusco NT100-100Pis a spin-down sediment filter with a 1-inch mesh made of PVC. It can function at a maximum pressure of 150p PSI, and the 100-mesh filter is excellent for filtering grit from a new well or fine sand from existing wells, depending on the application. After passing through the spin-down filter, water is directed through the housing by means of the head, which directs the water in a circular motion. This centrifugal force traps particles of silt within the filter mesh, allowing them to be removed from your well water through the filter.

However, when compared to the iSpring, it is entirely constructed of plastic and does not appear to be as sturdy or lasting.

It is necessary to wrap Teflon tape over the threads in order to reduce the possibility of leaking. However, we have found that this is the most cost-effective sediment filter for well water that we have come across. Pros

  • Cost effective
  • Flushable
  • And reusable. Removal of material by centrifugal force
  • It does an excellent job of eliminating sediment.
  • Design made entirely of plastic is not long-lasting. leaking from the seal’s perimeter

3.iFilters Well Water Filtration System – Premium Choice

TheiFilters filtration system is a whole-house system that consists of a housing and a two-stage sediment filter that is designed to remove sediment. Because of the pressure release mechanism, replacing the filter is much simpler and less messy than in the previous model. As a whole-house system, it is a very small device, and the fact that it includes the filters as well as the housing helps to keep prices low. Unfortunately, when it comes time to change the filter, you will have to replace it with another of the same type and size as the original.

The filtering system consists of a pleated sediment filter with a 30-micron pore size.

All of the necessary components for installation are included in the package, which includes a sturdy bracket, housings with a pressure relief button, as well as a wrench.


  • System with two stages of sediment filtering
  • The entire package is included
  • Reduces the amount of chlorine and heavy metals in the water, as well as sediment

4.iSpring WSP50GR Sediment Water Filter

ISpring WSP50GR features a stainless-steel mesh that has been tested to a micron rating of 50 microns. It makes use of centrifugal force to guide water after it has been gone through the filtering chamber. The filter cartridge and housing are both readily cleaned, and the double-sided scraper ensures that the unit is properly cleaned, which helps to avoid clogging of the subsequent filter stages. The filter cartridge and housing This device includes a rotating head that can be rotated 360 degrees, making installation quick and simple.

The 50-micron mesh is a nice middle ground that is suited for both well water and municipal water applications.

The manufacturer says that it allows for a water flow of up to 15 gallons per minute; however, after a few weeks, we discovered that it was limiting flow.


  • Parts of superior grade
  • Installation is made easier with the rotating head. A pressure gauge for precise monitoring is provided. flushable and re-usable materials

5.Culligan WH-S200-C Whole House Sediment Water Filter

Despite the fact that the WH-S200-Chas has a 3/4-inch inlet/outlet and can manage water pressure up to 125 PSI, some purchasers have reported that it is unable to withstand this amount of pressure and that they have encountered a significant drop-off in water pressure. It does feature a transparent casing, which allows you to see inside and makes it easy to tell when the filter needs to be cleaned or replaced. Although the inlet/outlet pipe provides sufficient water flow for small to medium-sized homes, you might consider upgrading to a bigger 1-inch or even 2-inch connection for large properties and commercial applications.

Yet, despite this, the Culligan is around the same price as some of the higher-quality rivals. Pros

  • Suitable for modest to medium-sized dwellings
  • Housing that is transparent to allow for simple monitoring
  • The bypass valve enables for filter replacement without shutting off the water supply.

Buyer’s Guide – Purchasing the Best Sediment Filter for Well Water

It is necessary to filter out any type of sediment from well water before it is delivered to your faucets and appliances. Sand, grit, and other heavy metals may all be found in sediments, as well as iron. This procedure is normally carried out by running the water through a small mesh or screen to remove any debris. It is possible for the mesh to get clogged and dirty as a result of the physical capture of silt by the mesh. Regular flushing of the filter may be required, and it will be beneficial to do so.

When utilized as part of a whole-house system, sediment filters are most typically employed in conjunction with other stages of filtering, such as carbon filters and heavy metal filters, to achieve the best results.

Types of Sediment Filter

Spin-down sediment filters and cartridge sediment filters are the two most common types of sediment filters for households with well water.

  • The water is sent through the spin-down filter such that it spins around the mesh core of the filter. Gravity drives the sedimentary materials outward, where they become entangled in the mesh as a result of the centrifugal force. With the way that these filters are constructed, they are less likely to cause a decrease in your water pressure, and they may be used with water supplies that have pressures of up to 150 PSI, although this will vary depending on the specific model that you choose. The fact that the mesh nets of this sort of filtration system can generally be cleaned is another advantage of this type of system. Cleaning and changing the net eliminates the need to purchase new filters as frequently, extending the life of the filters while also guaranteeing that they work at their peak for a longer period of time. Because the casing does not need to be changed as frequently, the overall cost of these devices is reduced even more. Because well water contains more sediment particles than municipal water, the spin-down filter is typically favored over cartridge replacement filters.
  • The job of cartridge sediment filters is generally performed by gravity. The water is forced straight into the mesh net, where the particles are trapped and gathered. It is feasible to clean and reuse the mesh in this sort of filtration system when dealing with tiny sediment particles, although it is not always practical. When the cartridge becomes blocked or unclean, it is necessary to replace the entire cartridge. It is possible that the cost of replacing well water on a regular basis will become too expensive if you have very unclean well water.

Water Flow Requirements

When selecting a filtering system, the flow rate of the water should be taken into consideration. The filter must be able to handle the volume of water coming from your water source. If you select a filter that has a lower flow rate capacity than your peak water flow, you will experience pressure loss in your system. As a result of the reduced effort required to operate faucets, showers, and even washing machines, you will begin to notice a change in the amount of water that comes out of your taps.

The pore size of a sediment filter mesh is measured in microns, and it influences the size of sediment particles that may be efficiently removed from water using a sediment filter system. With a lower micron rating, a finer mesh is used, which results in smaller silt particles being removed from the water. As a result, it may appear that the best solution is to just choose the micron rating with the lowest possible value. However, this is the incorrect option. If your water contains significant bits of rust or metal, and you choose a smaller mesh size, the filter will soon become clogged with these contaminants.

If you have washable and reusable filters, you will need to wash and replace the filter on a regular basis in order to have a sufficient flow of water.

Although mesh size needs vary from one application to another, the following can serve as a basic guideline:

  • Sand, grit, and pipe scale are all regarded appropriate for a 150-micron mesh screen. Very fine sand and grit are processed via a 100-micron filter. Fine, dust-like silt will be captured by 15-micron filters.

If you have a range of various forms of sediment in your well, it is probable that they will alter over time and over the life of the well. If you get your water tested, you will be able to determine the ideal micron mesh size.

However, experimenting with other mesh sizes may yield the same results. If your water contains a diverse range of sediment types, you will want a multi-stage filtering system to guarantee that you are receiving clean and debris-free water from your well or other source.

Durability and Lifespan

You don’t want to have to change your filter every few days, therefore make your filter last longer. It’s expensive, it’s impractical, and it’s a pain in the neck. The frequency with which you should change your filter is typically governed by how much water you use. While a single person who works all day and uses very little water in the evenings will get the most life out of their cartridges, a family of six who lives in a four-bedroom house and uses a lot of water constantly throughout the day and night will struggle to find filters that will last more than a couple of months.

  • A common method of determining the life expectancy of a filter is to count the volume of water that can be filtered before it has to be changed, however some manufacturers provide an anticipated period.
  • Unless you are dealing with contaminated water that contains sediment particles, it is doubtful that you will meet the manufacturer’s stated timetable for completion.
  • In addition to the frequency with which you flush or clean your filtration system, the size of the filter is another consideration.
  • When the water is flushed, it is collected in a bucket or other container and disposed of properly.
  • Always check to be that all of the detergent has been completely gone before replenishing it.
  • Cleaning the filter, if possible, may significantly improve its efficiency while also extending its life.


A sediment filter is particularly beneficial for houses and other establishments that obtain their water from a local well. Use as the first step in a three or more stage filtering process, it ensures clean drinking water, and it may protect you, your family, pets, and even water-based products from potential danger. It is available in a variety of sizes and configurations. There is a broad number of possible filters to pick from, with a wide array of filters available from manufacturers like as Rusco, Culligan, and iSpring, among others.

But what exactly is it that these filter systems are designed to remove? And how does your water filtration system differ from the one installed by your next-door neighbor?

As a result, the sort of whole-house water filter, or cartridges, that you require will differ.

As a result, before purchasing a water filter, you must first evaluate the specific problem that is occurring with your water.

Physical Whole House Water Filter Cartridge Types

In order to remove solid particle matter from your home’s water, physical filters must be utilized. For example, if your water contains debris such as sand, silt, or sediments, physical filters are excellent for removing these contaminants from the water.

Sediment Filters

Sediment filters are the first sort of whole-house water filter cartridge that we’ll talk about in this article. There are three subcategories in this section: All of these filters trap solid particles inside one or more layers of filter media, enabling only clean water to pass through. It’s important to note that most physical filters will not remove pollutants, heavy metals, salts, or tiny organisms from your drinking water. Instead, they are only interested in huge bits and fragments that are typically more than one micron in size.

Surface Filter Cartridges (Pleated)

These entire house filter cartridges, which are commonly referred to as “pleated filters” (because to their acorn-shaped structure), include a thin layer that catches all of the dirt. The pleated design of these filters increases the amount of surface area available. Thus, they have a greater ability to trap particles, allowing filtered water to be available for a longer period of time. What else is there to say? They are washable and reusable at least a couple of times, so you won’t have to spend money on them all the time.

Depth Filter Cartridges (String Wound, Melt Blown)

The taste of dirt and rust in your tongue after taking a huge drink of water is one of the most horrible things you can imagine! The good news is that depth filter cartridges come to the rescue. By forcing water to travel through a thick wall of filter material, these filters effectively remove rust, silt, and other contaminants from water. Depth filters are available in a number of different materials, including glass fiber, cellulose, ceramic, polyester, and polypropylene, to name a few. The graded-density structure of some of them distinguishes them from the others.

The filter tightens as more water runs through it, allowing it to collect the largest particles first and trap all of the smaller ones together in its center. The construction of incremental density filter cartridges allows them to have a much longer service life since clogging is postponed.

Absorptive Filters

Absorptive filters have lately increased in popularity, and for all of the correct reasons as well. They are available in two different formats: deep and pleated. Many of these filter cartridges employ electrokinetic absorption, which attracts and holds negatively charged bacteria in suspension. Furthermore, they are capable of trapping ultra-small particles that would otherwise pass through conventional filters. Most of the time, they are designed to collect particles with sizes as tiny as 2 microns in diameter, but they can also capture colloidal materials with sizes less than 2 microns in diameter.

Ultrafiltration Cartridges

Proteins, colloids, viruses, bacteria, parasites, pyrogens, and other organic substances larger than 0.01 micron in size are removed by ultrafiltration (UF) cartridges, which are used in water treatment. Furthermore, certain UF systems already in use remove herbicides and pesticides while also lowering hardness and salt levels in the water.

Reverse Osmosis Membranes

Reverse osmosis membranes are capable of removing even the smallest of particles. For example, they are capable of rejecting viruses and other microbes as tiny as one-thousandth of a micron in size and smaller. Simply said, these membranes are capable of removing virtually any substance from your water, including tannins, pesticides, nitrate, heavy metals, and other contaminants.

Micron Ratings

The micron is a standard measurement unit used by filter manufacturers to measure the size of their products. For example, a sediment water filter cartridge for a full home may have a micron rating of 5 or 10 microns. Are you curious as to how much that is? As a comparison, your hair is around 70 microns in diameter, and some sediment filters can collect particles as fine as submicrons – which is extremely small. The micron ratings of the filters are assigned by their makers. They describe the efficacy of eliminating particles of a specified size from a given environment.

Nominal vs. Absolute

Typically, a nominal micron rating indicates that a filter blocks 80 percent or more of the particles of the stated micron size, depending on the filter. Put another way, a water filter with a nominal rating of one micron can remove around 80% of particles in your water that are one micron or bigger. Absolute ratings, on the other hand, imply that a filter cartridge is capable of successfully removing all particles of a certain size from the environment. These filters are employed in situations when efficiency is critical.

That said, if a filter claims to eliminate Salmonella from your water, you should not rely on a filter that guarantees 80 percent efficiency because it is unlikely to be effective (i.e.

As a result, absolute micron ratings will very certainly be required (perhaps a 3-log or 4-log rating at a bare minimum).

For example, some nominal filter manufacturers consider rejection rates of 75 percent to be sufficient; others need rejection rates of at least 80 percent. As a result, the definition varies from manufacturer to manufacturer, and customers have no method of verifying claims.

Common Chemical Whole House Filter Cartridge Types

A number of pollutants, ranging from pesticides to trihalomethanes, can find their way into your drinking water supply. The good news is that you can eliminate the most of them (if not all) by using an effective chemical filter. We’ve included some of the most common chemical whole-home filtration cartridges in the section below.

Granular Activated Carbon Filtration

Granular activated carbon is a porous substance that filters pollutants from water by adsorption and chemical reactions. It is made from highly adsorbent and porous material. In addition to eliminating pollutants such as pesticides and disinfection byproducts, it is one of the most preferred whole house filter media since it reduces poor taste and odor as well as chemical contaminants. Given its ability to handle larger flow rates than carbon filter blocks (which are discussed below), granular activated carbon filter cartridges are more typically employed in whole-house applications than carbon filter blocks.

Carbon Blocks

Carbon filter blocks are constructed from activated carbon that has been bonded together using a binder. Afterwards, the mixture is molded and squeezed to form a cartridge filter in the required shape or size for the application. Carbon blocks have a nominal filter capacity ranging from 0.5 to 10 microns. So they can readily reduce lead levels, as well as the presence of cryptosporidium and Giardia in some situations, in addition to decreasing chemical levels.

Catalytic Carbon Filter Cartridges

While ordinary activated carbon filters are successful at removing the vast majority of pollutants from water, they are ineffective at removing chloramines from the water (a chemical used more and more these days for tap water disinfection). In rare cases, chloramines can be an issue. They are more stable than chlorine, but they are also far more difficult to remove. Furthermore, they produce undesirable byproducts, which have been demonstrated to have negative health consequences. Because GAC can not effectively remove chloramine, a catalytic carbon filter cartridge is required to completely eliminate the toxin.

KDF Filter Cartridges

KDF filter cartridges work by utilizing redox reactions to remove water contaminants from the system. The copper-zinc mix may eliminate chlorine, lead, hydrogen sulfide, chromium, mercury, and more. What’s more, it inhibits bacteria and other organisms from collecting in the filter system. The two primary types of KDF are: KDF is frequently used in conjunction with carbon-based filters to target a broader spectrum of pollutants.

Iron Filters

Iron filters, as the name implies, remove iron, which is commonly found in well water. First, they oxidize soluble ferrous iron to solid ferric (rust), resulting in the formation of ferric oxide. When the rust gets into the filter medium, it becomes stuck there.

Ion Exchange

Ion exchange whole house water filter cartridges are designed to target certain groups of impurities that other filter types are unable to remove.

They are particularly effective at removing/reducing inorganic compounds like as arsenic, sulfate, and other negatively charged pollutants from the environment.

Activated Alumina

The activated alumina grains in these filters help to keep the filters clean. The majority of the time, AA is utilized to absorb arsenic and fluoride. Uranium and thallium are two more pollutants that may be removed from water.


There is a reason why these are referred to as UV filter cartridges. In the canister is a lamp that produces ultraviolet light, which kills germs such as bacteria and other pathogens. The UV radiation damages the DNA of the bacteria in question, rendering them inactive in the water and preventing them from reproducing. This distinguishes UV filter cartridges from traditional water filtration systems, in which water is normally passed through a filter material before reaching the final destination.

Whole House Water Filter Cartridge Sizes

There are four primary varieties of water filter cartridge sizes, which are as follows:

  1. The dimensions are 2.5 x 10 inches, 2.5 x 20 inches, 4.5 x 10 inches, and 4.5 x 20 inches.

Filters with dimensions of 4.5″ x 10″ and 4.5″ x 20″ are often utilized in whole-house applications. Smaller diameters may be preferred by certain individuals (in order to save money), but they reduce pressure flow, making them an undesirable choice in the majority of circumstances. Furthermore, you can select from a variety of proprietary sizes, however this is not encouraged for a number of reasons, including:

  1. For starters, they are more expensive. First and foremost, you would have a tough time finding adequate alternatives in the event of the company’s liquidation or product discontinuance.

As a result, selecting a general-purpose filter size is always the best option.

Flow Rates

The flow rate varies based on the type of filter material used and the size of the cartridge. For example, when compared to a smaller cartridge, a bigger cartridge will always have a higher flow rate than when compared to a smaller cartridge. Decreased flow rates are also observed in sediment filters with high micron ratings when compared to carbon block filters of the same size. Generally speaking, the tighter and narrower a filter cartridge’s internal dimensions, the slower the maximum flow rate will be.

  • A 50-micron absolute pleated sediment filter produces 10 gpm
  • An 8-micron absolute poplypropylene spun sediment filter produces 8 gpm
  • A 3-micron nominal granular activated carbon filter produces 25 microns nominal granular activated carbon
  • A 4-micron nominal activated carbon block filter produces 4 gpm
  • And a 5-micron nominal activated carbon block filter produces 4 gpm.

Which Type of Filter Cartridge For Your Water Problem?

The sort of water filter cartridge you require is determined by the type of water problems you are currently facing. Furthermore, whole-house filters provide you the flexibility to experiment with different filter cartridges to discover the one that works best for your particular situation. As a general rule, one or more sediment pre-filters should be installed as your first line of defense. They are responsible for collecting dirt and debris in order to preserve the succeeding filter stages.
