Each product that we showcase has been picked and vetted by our editorial staff after being thoroughly researched and tested. If you make a purchase after clicking on one of the links on this page, we may receive a commission. Water is at the top of the list of all the items that are required to live a healthy existence. Despite the fact that many individuals in the United States have access to water through taps, two million people do not have access to uncontaminated water. Furthermore, according to the United States Environmental Protection Agency, the number of pollutants that might render water unfit for consumption is enormous.

Why are water filters important?

The professional dietician nutritionist Maya Feller of Maya Feller Nutrition says that water filters not only improve the taste of water, but they also eliminate potentially dangerous impurities such as physical, chemical, biological, and radioactive components. “Heavy metals, medicines, and certain pesticides are removed by these purifiers and filtration systems,” Feller explains to Health magazine. “If we don’t drink pure water, it’s truly damaging to our health,” says the author. A water filtration system is essential for protecting your family from illnesses caused by bacteria, pesticides, E.

Ingesting contaminated water has been linked to gastrointestinal illnesses, cancer, and reproductive effects as well as not-so-good symptoms such as stomach pain, vomiting, diarrhea, and fever, underscoring the importance of having one in place.

How do water filters work?

It has been reported that water filters not only improve the taste of water but they also eliminate dangerous toxins such as physical, chemical, biological, and radioactive components, according to Maya Feller MS RD CDN, certified dietitian nutritionist of Maya Feller Nutrition. Heavy metals, medications, and certain pesticides are all removed by these purifiers and filtration systems, according to Feller, a health expert. In fact, if we aren’t drinking pure water, it might be detrimental to our health.

coli, or heavy metals has been linked to gastrointestinal illnesses, cancer, and reproductive effects, as well as less-than-pleasant symptoms such as stomach pain, vomiting, diarrhea, and fever, underscoring the importance of installing a water filtration system in your home or office building.

How to choose the best water filter?

The ideal water filter for you will be determined mostly by your budget and the amount of water purification you require. The following is an excerpt from Mia Syn, MS, RDN’s interview with Health: “Various units remove different pollutants or classes of toxins from water.” Mia Syn is a registered dietitian located in Charleston, South Carolina. In the case of those in need of a filter that can handle heavy-duty cleaning, Syn suggests reverse osmosis systems since they are effective “Using high pressure, drive water through a semipermeable membrane, allowing pollutants to pass through.

Reverse osmosis systems are perfect for treating flowing water from the faucet as well as fresh water sources from streams and rivers, among other things.

Filters that utilize granular-activated carbon, on the other hand-which are often found in water pitchers and filtration bottles-absorb pollutants that cause water to taste bad.

The best water filters and purifiers

Generally speaking, “a high-quality water purifier is a great investment because it requires little maintenance, saves you money in the long term, improves the flavor of your water, and improves your health,” according to Syn. You’ll find the seven greatest water purifiers and filters in this section, which will save you money while also removing microorganisms with every pour.

Best Overall: Big Berkey Gravity-Fed Water Filter

Feller highly recommends this filter since it does two functions at the same time. A purifier and filter in one, it removes more than 200 pollutants from tap water, ponds and streams, and other sources of drinking water. There are no pumps required because the system operates on a gravity-feeding principle. This filter, which measures 19.25 by 8.5 inches and contains 2.25 gallons of water, is perfect for families of up to four people because of its small size. Furthermore, because it does not rely on power or plumbing, this device is completely transportable as well.

  • The following symptoms are common: nausea, developmental issues, stomach discomfort, diarrhea, thyroid illness (over time), cancer (over time), and more.

A water filter is a must-have if you want to drink genuinely pure water. So let’s have a look at which water filters remove the most impurities and how they may assist you in ensuring that you have a clean and contaminant-free source of drinking water in your home.

How Exactly Does A Water Filtration System Work?

The water that we use on a daily basis travels through a series of stages known as the water cycle. In other words, it’s always moving and circulating throughout the environment. It is possible for it to be flowing through a river one minute and flushing down your toilet in the next. As reported by the Water Quality Association, there are more than 80 pollutants that may be identified in drinking water at any given time. This is due to the fact that water has an incredible ability to attract and dissolve dirt and a variety of other compounds.

Mostly because you have no idea what impurities your water has attracted as a result of the treatment process.

In order to assist remove the particles, the filter may be equipped with a solid carbon block media or a fine textile membrane.

Chemical filtration eliminates dissolved particles from water by passing it through an active substance that, as the water flows through it, helps to enhance the water’s overall quality.

How Do You Know If Your Water Is Really Clean?

Data will be used to determine whether or not your water is safe to drink. For those who use municipal or county-provided water, there is information accessible on the United States Environmental Protection Agency (EPA) website about how to protect the environment. If you happen to be utilizing private water from a well or another source where you aren’t sure about the quality of the water, you may obtain a home water quality test kit from the comfort of your own home.

Look for a test that is manufactured in the United States. They’ll be able to distinguish between the following:

  • Pesticide
  • sLead
  • sIron
  • sCopper
  • spH
  • sHardness
  • sBacteria
  • sAlkalinity
  • sChlorine

These tests normally involve strips that’ll change colors dependent on the pollutant that’s in your water. This will tell you precisely what pathogens are in your water and how many there are. However, the disadvantage of using home testing is that they are not always reliable and may not detect every conceivable drug that might be detected. If you are serious about finding out exactly what is in your water, the most trustworthy option is to contact a state-certified laboratory for a water analysis.

What Should You Look for In A Water Filtration System?

With so many different types of water filters to select from, it may be tough to determine which one is the best fit for you and your specific environment. However, there are a few crucial characteristics that you should look out for regardless of your situation.

The Filter’s Lifespan

There will be a need for filter replacement at some point regardless of the type of filter you use. This will depend on how many pollutants are present in your water, how hard your water is, and quite a few other factors. An average water filter should last between 6 and 12 months before it has to be replaced with a replacement cartridge element. In the case of a filter, the package should include information on how to change it as well as when it should be replaced.

Filtration Process

Diverse pollutants will be removed by different types of filters. While some only filter out the most basic contaminants that can improve the overall flavor and safety of your water, others go a step further and are capable of filtering out bacteria and other hazardous diseases that are more difficult to remove. Choosing the right filter for your water is important.

Pitcher, Faucet Mount vs. Permanent

Different water filters will perform a variety of tasks and are capable of serving a variety of objectives. Some can enhance the flavor of your drinking water, while others will totally filter out toxins that are more difficult to detect in the first place. Water from the tap will naturally include small amounts of a variety of chemicals, some of which are healthy. Your body need dissolved minerals in order to maintain optimal health.

Check The NSF Rating

To find out exactly what a water filter accomplishes, look for the NSF certification logo on the filter. NSF International is an independent organization that develops standards for items that are intended to protect public health. If you look for a certain filter in the NSF database, you will be able to immediately determine which germs it will protect you from.

The Four Types Of Water Filters

There are several different types of filters, and each one performs a somewhat different function in terms of decontaminating your water.

Activated Carbon Filter

The activated carbon filter makes use of activated carbon granules, which adsorb chemical contaminants and remove them from the water. The little particles of carbon have been processed in such a way that they are extremely “sticky.” The large amount of surface area allows for efficient adsorption of chemicals and contaminates on the surface. Once the water begins to flow through the carbon filter, the chemicals present in the water are attracted to the filter and adhere to it, resulting in purer water being produced.

However, while activated carbon filters are excellent at eliminating chlorine-based pollutants, they are less effective at removing heavy metals such as fluorine, nitrates, and salt.

Ion Exchange Filter

Ion-exchange filters function by separating atoms of a contaminated chemical into ions, which are then removed from the system. They are most recognized for their ability to reduce hardness in water. If you’ve ever brewed coffee that tasted chalky, thick, or dull, it was most likely due to the hardness of the water you used. Hard water has high concentrations of magnesium and calcium, which causes transient hardness and may contribute to the alkalinity of the water. During the passage of hard water through an ion-exchange filter, the chemicals are separated and transformed into calcium and magnesium ions.

Following the trapping of incoming magnesium and calcium ions by the filter, the filter releases its own sodium ions as a substitute, which causes the water to become softer.

Distillation

When purifying your water using distillation, there is no need for any additional equipment because the process is completed by boiling the water. Alternatively, you might purchase a water distiller specifically for this purpose. Chemicals and many other sorts of pollutants are not removed from water by boiling. Condensing contaminated water into a separate container after heating it to a boil and catching the steam is a simple way to remove pollutants from water. Water boils at a lower temperature than some impurities, which means that they are left behind as the steam is expelled from the system.

Reverse Osmosis

When polluted water is pushed through an ultra fine filter under high pressure, the pollutants in the water are removed from the solution. The semipermeable membrane has incredibly thin holes constructed into it, which prevent pollutants from passing through while also enabling water to travel through it. When water passes across a membrane, it becomes more concentrated in an effort to achieve balance on both sides of the membrane. The process of reverse osmosis really prevents pollutants from accessing the side of the membrane that is not consented to.

The Facts Are All Laid Out In Knowing Which Water Filter Removes The Most Contaminants

Following your understanding of how water filters function and the benefits they may provide, it’s time to move on to picking the filter that will best suit your needs and those of your loved ones. The easiest method to determine which sort of filter you require is to make a list of the contaminants in your water that you are most worried about and use that list as a guideline. “I’ve been using these water filters for many years now,” one of our clients recently stated. They improve the flavor of our water and demonstrate how much cleaner our water is when we examine the filters after they have been replaced!

Each and every one of us should have one.”

The Water Filter That Removes More Contaminants Than Any Other

Choosing the finest water filter for your house is easier said than done – it is critical to understand which types of impurities are removed by distinct types of water filters. Using a water filter is always a smart idea, regardless of whether or not your tap water source fulfills quality requirements. Distillation eliminates more pollutants from water than any other type of filtering or purification process available. Heavy metals, organic compounds, microplastics, and mineral ions are removed during the distillation process, while bacteria and viruses are killed at the same time throughout the process.

However, before purchasing a water filter for your house, it is recommended that you test your water supply to determine what toxins are present in your water. It is possible that a mix of diverse purification approaches is the most effective strategy for purification.

Methods of Water Filtration

Here is a list of the toxins that each type of water filtering and purification is capable of removing from water. Continue reading to learn more about each option, as well as which filters and purifiers are the most effective on the market today.

Method Heavy metals Mineral ions Microplastics Microbes Viruses
Distillation ✓ / ✗
Reverse Osmosis ✓ / ✗ ✓ / ✗
Filtration (carbon) ✓ / ✗ ✓ / ✗
Ultraviolet (UV)
Water Softeners ✓ / ✗

Distillation

Distillation is a water purification procedure that involves the boiling of water followed by its quick cooling. Impure water is cooked in order to eliminate any bacteria or pathogens that may be in the water. After that, the steam is collected and re-condensed to produce clean, purified water. The vast majority of microorganisms are either destroyed or thermally inactivated. As a result of the evaporation of water, heavy metals, organic molecules, and mineral salts are left behind as solids.

Distilleries can be used to extract arsenic, cadmium, nitrates, sulfates, phosphorus, magnesium potassium, calcium and sodium, microorganisms, and copper from a variety of materials, including water.

However, because distilled water has been devoid of its mineral salts, it may have a bland and flat flavor.

Reverse Osmosis

Reverse osmosis (RO) is one of the most effective water purification processes available since it significantly decreases the quantity of total dissolved solids (TDS) in the water being treated. RO is a method of filtering water that employs a semi-permeable membrane to remove suspended particles, heavy metals, and dissolved pollutants. This membrane is put between two vats of water, each of which contains water with varying amounts of pollutant contaminants (as a solute). A pressure gradient is employed in order to transport water from one zone of high contamination concentration to another region of low contamination concentration, and vice versa.

Only water molecules are allowed to flow through the holes of the semi-permeable membrane, which is composed of a polymer matrix.

As a result, pollutants such as fluoride, arsenic, nitrate, radium, and uranium are present.

Filtration (carbon filter)

As a result, it is one of the most effective filtration techniques available since it significantly decreases the quantity of total dissolved solids (TDS) present in water. In order to remove suspended particles, heavy metals, and dissolved pollutants from water, RO employs a semi-permeable membrane as its filter. Using this membrane, water is separated into two vats, each of which contains water carrying varying quantities of pollutants (as a solute). In order to transfer water from one location of greater pollutant concentration to another of lower contamination concentration, pressure is applied to the water.

Doar water molecules can flow through the holes of the semi-permeable membrane comprised of a polymer matrix.

Water is removed from the equation, but molecules bigger than water (including heavy metals, dissolved and suspended particulates) are left in the equation. Therefore, pollutants including fluoride, arsenic, nitrate, radium, and uranium should be avoided in drinking water sources

  • Microfiltration is the use of a filter with a pore size ranging between 0.1 and 10 microns
  • Ultrafiltration is the use of filters with pores ranging between 0.1 and 0.01 microns
  • And Nanofiltration is the use of filters with pores ranging between 0.1 and 0.01 microns. Nanofiltration makes use of the finest filters available, with holes as small as 0.001 microns. The majority of microplastics are eliminated at this level.

However, these filters are unable of removing dissolved minerals, bacteria or nitrates. They are capable of removing pesticides, organic compounds, chlorine and chlorine compounds, as well as microplastics. Because of their small pore size, nanofilters are technically capable of removing viruses. In RO systems, carbon filters are frequently utilized in addition to the semipermeable membrane to improve efficiency. Activated carbon cartridges are used in the construction of these filters (from coconut fiber or other sources).

Adsorption is the process by which particles adhere to the surface of an adsorbing substance (adsorbing material).

When contaminated water is injected into a carbon filter, the carbon filter serves as an initial filter.

UV

Ultraviolet (UV) light is a kind of non-ionizing radiation with a wavelength ranging from 100 to 400 nanometers. It is used to treat skin cancer. UV radiation is divided into three bands: UVA, UVB, and UVC. While ultraviolet A and ultraviolet B rays are damaging to human skin, ultraviolet C rays may be utilized to purify water. UVC has a wavelength ranging from 100 to 280 nanometers and can be emitted by both natural and manmade sources. Bacteria, viruses, and other organisms are killed by the germicidal capabilities of this substance.

UVC kills bacteria and viruses such as Pseudomonas, Salmonella, Clostridium, Staphylococcus, Saccharomyces, Penicillium, Mucorspores, influenza, hepatitis, poliovirus, rotavirus, and chlorella algae.

Under-Sink Filters

Water filters installed behind the counter or under the sink mostly employ RO, which may remove heavy metals, sulfates, calcium and magnesium ions as well as other contaminants such as organic compounds and hardness from the water. Microfiltration is also used by certain under-sink filters, which eliminates pesticides, chlorine compounds, and other suspended particles from the water. These cannot be used to eradicate germs from the environment.

Gravity-fed Filter

Gravity-based filters are most commonly equipped with a carbon filter mechanism. They are primarily employed in the removal of chlorine and chlorine compounds from drinking water (provided they have an NSF-42 certification). However, their GAC (Granular Activated Carbon) filter will not be able to remove dissolved minerals like potassium, magnesium, or calcium, as they do with arsenic and other heavy metals.

Softeners

Water softeners are used to soften naturally hard water that has accumulated over time. Hard water has significant concentrations of calcium and magnesium salts, ranging from 61 to 120 mg/L in hardness. Extremely hard water includes dissolved salts in concentrations more than 180 mg/L. The majority of groundwater is naturally hard due to the limestone it flows through underneath. Hard water is not very pleasant to drink and may cause scaly buildup in plumbing and home appliances if not treated properly.

Softeners do not remove any other impurities from the water; they are only used to lessen the hardness of the water and do not reduce the total dissolved solids (TDS).

Due to the fact that total dissolved solids (TDS) refers to the total amount of ­­ all dissolved materials, rather than simply calcium and magnesium salts,

Types of Water Filters

When it comes to purifying water, several types of water filters use a variety of filtering technologies. Examine some of the brands now on the market, as well as the impurities that each type of filter is capable of filtering.

Water Filter Pitcher

A portable, small, and reasonably priced water filtration pitcher is ideal for traveling. Activated carbon and ion exchange filters are often used to remove the following pollutants from the water:

What to Look for When Buying a Water Filter

Marshall Bright contributed to this article.

Purpose

According to Rick Andrew of NSF International, a health and safety standards testing business that certifies water filtration systems, there are two primary reasons to install a water filtration system: first, it is environmentally friendly. Water filters for drinking water in the United States are more likely to be used to enhance flavor or remove hard minerals and protect pipes, as hard water (i.e., water with a high mineral content) can cause buildup in pipes and water fixtures and eventually lead to pipe failure.

If you have well water, ancient pipes, or live in a region where drinking water is dangerous, you may require a water filter to remove pollutants such as lead or real particles such as sand from your drinking water.

Independent Certifications

In part because good filtration is so vital (and because it’s so difficult to detect whether or not it’s functioning), certification is one of the few ways to be absolutely certain that your water filter is actually eliminating the impurities it promises to be removing on its box. The National Sanitation Foundation (NSF) is one such certification authority. Others to check for include certificates from the American National Standards Institute (ANSI) and the Water Quality Association (WQA) (WQA).

See also:  Who Makes The Best Water Heater

For example, the National Sanitation Foundation (NSF) gives certification for eliminating a certain quantity of chlorine as well as a separate certification for removing lead.

Andrew advises that you should double-check to make sure it is genuinely certified before proceeding.

Capacity

When selecting a water filter, you should also take into account how much water your household consumes. Although a small pitcher may do for a dorm or an apartment, bigger homes (or those who wish to filter water for cooking as well as drinking) may benefit from faucet or under-sink filters, which are less expensive and more convenient. Although refilling a pitcher does not take much time, if you have to do it multiple times a day, it might be tempting to give up on it and simply return to drinking unfiltered water from the tap instead.

Replacement Filters

Another factor to consider is the cost of the filter. In order to get the most out of your water filtration system, consider all of the factors that influence its performance, including pricing, availability, and the frequency with which filters must be replaced before making your selection.

Cost

Water filtration systems can range in price from thousands of dollars to, in the case of a tiny pitcher, less than twenty dollars.

Water filters for home use are available at a reasonable price and do not require a large investment; nevertheless, search for certifications. When determining how much money you want to spend, keep in mind the cost of the water filter as well as how often it will need to be serviced.

Types of Water Filters

A pitcher is the first thing that comes to mind when we think of water filters, however water filters may be utilized at practically every step of the water’s path through your home.

Whole-Home Systems

Whole-house water filtration systems filter all of the water that enters your home. “The most typical type,” explains Andrew, “is a water softener, which will assist in the removal of minerals and the’softening’ of your water.” Because hard water is detrimental to pipes and water fixtures, a whole-house filtration system is the most practical solution. Due to the fact that this sort of system filters water for the entire house, it is sometimes expensive and time-consuming to put in place.

Under-Sink

The usage of a point-of-use filter is another alternative if you want to filter your drinking water for toxins or a particular flavor. These might be sink-mounted filters, or they can be located beneath the sink where you obtain your drinking water. If you don’t have well water, Andrew says whole-house filtration is usually primarily used for softening the water, and point-of-use systems are fine if you’re solely concerned with eliminating toxins. Compared to whole-home systems, under-sink filters are frequently less difficult to install; nevertheless, they are more costly than faucet attachments or pitchers.

Faucet Attachments

In the same way as under-sink filters do, faucet attachments provide immediate access to filtered water at a location where you would normally acquire drinking water, such as the kitchen sink. This type of filter may be fitted to the majority of regular sinks; however, it will not function with more unusual sink configurations, such as a pull-down faucet with a spray nozzle. A faucet attachment will often allow you to filter only the water you wish to drink while allowing unfiltered water to get through for things like dishwashing and other household chores.

This sort of technology also puts less strain on the filter because it only filters the water that is actually required.

Pitchers

The fact that pitchers must be replenished means that they do not provide the convenience of sink filters. However, according to Andrew: “some people like pitchers since they enable you to cool filtered water, which can make it more delightful to drink.” It’s also the most straightforward to set up. Furthermore, if you are merely filtering water for flavor, you may find a faucet filter to be cumbersome and unneeded while doing tasks such as washing dishes or washing your hands at the kitchen sink.

Countertop

Countertop water filtration systems function in a similar way to faucet filters in that they redirect water from the sink into a filtration system with its own water tap. Other countertop filtration devices, which function similarly to water coolers, must be refilled on a regular basis; they are often bigger than pitchers, but require less frequent refilling.

You may install filtered water wherever in your home, even if it is far away from a water supply, which is an advantage of using these systems.

Bottles

Water bottles may also filter water, allowing them to be recognized by the National Sanitation Foundation and the American National Standards Institute. As you fill your water bottle or drink from it, they may filter the water for you. Water bottles may be a terrific option if you want to drink filtered water while on the go, and they’re a great alternative to purchasing water bottles in the first place! Many home water filtration brands and filters, on the other hand, are intended to remove toxins from already treated water sources.

While filters of all kinds may perform an excellent job of eliminating pollutants, Andrew believes that “no filter is perfect.”

Brands

Nowadays, the phrase “Brita pitcher” is mostly used to refer to a water pitcher that has been filtered. Every one of Brita’s filters has received NSF certification, and its pitchers are well-known for their simplicity of use—just drop a filter into the pitcher and you’re ready to go. Brita also sells a variety of pitchers and filtration systems, such as faucet filters and water bottles, in addition to drinking glasses. Brita, on the other hand, does not provide under-sink or whole-home filtering systems, and not all Brita filters are equal.

Pur

Pur and Brita provide products that are fairly similar to one another: simple filters that remove impurities that affect taste as well as mercury and other toxins, and more costly filters that can remove lead as well as a larger percentage of contaminants and are thus more expensive. Pur does, however, provide the most number of certifications in both its basic and more costly filters.

APEC

Products from Pur and Brita are quite comparable, with the exception of the price. They both provide simple filters for taste removal that also remove mercury and other toxins, and more costly filters that can remove lead and a larger proportion of contaminants. When it comes to its most basic and most costly filter, Pur has the most certifications.

Maintenance

There is no such thing as a one-time purchase for water filtration systems, regardless of their size or kind. Filters are not indestructible; they will ultimately cease to be effective in filtering water. “This has the potential to have two consequences,” Andrew explains. The water may begin to flow more slowly through the filter itself as a result of these changes. More dangerously, the filter may eventually cease to be effective in filtering water, allowing pollutants to remain in the solution.

The National Sanitation Foundation (NSF) certifies filters to verify that they can continue to remove impurities for the duration of their specified lifespan, and even for a small amount of additional time at the end.

The solution will not operate indefinitely, adds Andrew. “However, at some time, it will just cease to function.” Changing your water filter on a regular basis

Accessories

A variety of accessories and add-ons have emerged as firms attempt to differentiate themselves in the filtration industry, including Bluetooth capabilities and sensors to monitor filter efficacy. While these might be visually pleasing bells and whistles, they are not absolutely required. In other cases, such as when replacing filters, the sensor is not required if you follow manufacturer directions. In the end, what counts is whether or not the filter itself is capable of eliminating the contaminants that you desire to be eliminated.

FAQs

Water filtration systems come in a variety of shapes and sizes, and none of them are necessarily better (or worse) at filtering out toxins than another. Based on how it was produced and approved, the same types of filters may remove a wide range of impurities. In order to avoid this, Rick Andrew suggests that you identify the kind of pollutants that you want to be eliminated rather than merely seeking for a filter that eliminates a large number of contaminants. If you are unaware of what is in your local water, you may obtain a water report to determine what is present.

Do water filters remove bacteria?

Despite the fact that the National Sanitation Foundation certifies filters that eliminate germs under a standard called P231,” Andrew explains that they are often built for activities such as camping, where you may need to drink water from a stream. If you have special worries about bacteria in your drinking water, make sure to get a filter system that has been certified specifically for bacteria removal.

Can you filter any type of water?

In a nutshell, certainly. Water filters may be utilized with both city and well water, as well as with both soft and hard (high mineral content) water. Simply be conscious of what it is that you are attempting to eliminate. A whole-house system meant to remove minerals from hard water, for example, will not function the same way as a pitcher designed to remove chlorine for flavor.

Do water filters remove fluoride?

Yes, there are some who do. If you have a preference, make sure to double-check the certification of your filter.

How long do water filters last?

Water filtration systems are only as effective as the filters that are included within them. Every filter is intended to be changed, and all certifications are performed with the filter’s long-term performance as a consideration. If your filter has to be updated every six months, NSF will test each filter to guarantee that it has a six-month life span before it is placed in service. The filtration system itself can endure for several years if the filters are updated on a regular basis.

Donna Currie has lived and worked in sections of the country where the water quality was ranked among the best in the country.and she has lived and worked in places where the water quality was rated among the worst in the country. Over the years, she has put a number of models through their paces and conducted extensive study on the rest.
