How To Install Pur Water Filter Cartridge

How to Replace a Pur Water Filter

Article in PDF format Article in PDF format The company PUR offers a variety of solutions for purifying water, however the filters lose their effectiveness over time as they become clogged with impurities. The method by which you replace the filter is dependent on the system you’re using. Soak the new filter in a plastic jug or dispenser that you keep in the refrigerator before screwing it in. Remove the old filter from any filtration devices that attach to your sink faucet before installing the new one in its place.

  1. 15 minutes after soaking the new filter in cold water, remove it from the water. In a clean container that is deep enough so that the filter may be completely submerged, place the new filter. Allow at least 15 minutes after filling the container with cold water before using it again. Excess carbon from the filter will lift out and separate during this period, preventing it from getting into your drinking water.
  • Additionally, soaking the filter makes it more likely that water will flow evenly when you use it. It is not recommended to use water that is hotter than 86 degrees Fahrenheit (30 degrees Celsius) since it may harm the filter.
  • Not recommended: Do not use third-party filters with your PUR pitcher or dispenser since they may not fit as well as they should or have not been tested as well
  • 2 To remove the old filter, turn it counterclockwise from the center. Remove the lid from the pitcher or dispenser and place it somewhere safe. Take out the pour tray, which is the blue plastic reservoir on top of the stove and pull it out of the way. Holding the cylindrical filter from the bottom, spin it counterclockwise until the filter is unhooked from the cylinder filter. The old filter should be removed via the top of the pour tray and disposed of in the trash
  • Please wait until the pour tray is completely empty before changing your filter
  • Otherwise, it may be difficult to remove or you may spill
  • And

  • s3 For 10 seconds, run the new filter under the faucet to clean it. When the filter has completed soaking, remove it from the container and place it directly beneath your faucet to drain. Turn on cold water and spin the filter so that it may be properly rinsed out before continuing. Shut off the water and shake off any surplus that may have accumulated in the filter after 10 seconds of operation.
  • It is not recommended to use hot water to rinse the filter since it may harm it.
  • 4 To secure the filter in place, screw it into the pour tray in a clockwise direction. Pulling the long, cylindrical section of the filter through the opening in the middle of the pour tray and pushing it all the way down until it stops working is the goal. Continue to spin the filter clockwise until you hear it click into place while holding it at the bottom. Check to see whether the filter pops out of the pour tray by tapping on the end of the filter with your finger. Before reinstalling the cover, place the pour tray back into the pitcher or dispenser to prevent spills.
  • If the filter does come loose from the pour tray, it is because you did not secure it correctly. Replace it and try turning it in the opposite direction as the first time. PUR filters for pitchers and dispensers are typically good for 40 gallons (150 L), or around 2 months of use.
  • 5 To reset your pitcher or dispenser, hold the Reset button down for 5 seconds (if it has one). Some of the more recent PUR pitchers and dispensers are equipped with sensors that alert you when it is time to replace the filter. Remove the filter and push and maintain pressure on the Reset button on top of the lid for 5 seconds right after you reinstall it. Once the sensor has been reset, a green light will begin to flicker on the lid.
  • Older pitchers or dispensers may not have an electrical display
  • This is especially true for older models.
  1. 1 Remove the filter system from your faucet by unscrewing it. The weight of the filtration system should be supported by your nondominant hand in order to prevent it from falling and breaking. In order to release the plastic locking nut that is securing the filter system to the faucet, turn it counterclockwise. Once you have completely unscrewed the system, carefully pull it away from the faucet and place it on a surface or a towel.
  • When you remove the filter system from the faucet, water may flow out of the faucet. Some kinds of PUR filtering systems may attach to the faucet using a snap-on mechanism. It may be necessary to pull it straight down from the faucet if it is unable to be unscrewed.
  • 2 Remove the old filter from the system by twisting open the top cover of the system. Maintain the filtering system in such a way that the rounded end of the huge cylinder is pointing up. Remove the top of the cylinder by spinning it counterclockwise, and then set the top cover aside for now. Remove the old filter from the system and dispose of it in the garbage.
  • The top cover is always located on the opposite end of the spout from which water is dispensed.
  • 3Insert the new filter into the system and secure the cap with a screwdriver. Make sure the narrower end of the filter is at the bottom of the filter and that the logo is facing the correct way up. Fill up any gaps between the filter and the filtration system with water until the filter is snug. Replace the top cover over the filter and screw it back into place to keep it in place, as shown. 4 Reattach the filter system to the faucet where it was removed. Keep the filtration system flush against the bottom of the faucet so that the threadings are completely horizontal
  • Otherwise, the seal will not be as tight as you’d like it to. Tighten the locking nut onto the faucet by rotating it clockwise and continuing to tighten it until it is hand-tight. Turn on the water and check to see that it is not dripping or leaking at the seam.
  • Instead of screwing it on, line it up with the faucet and apply hard pressure to snap it into place.
  • 5 For 5 minutes, run cold water through the filter system to clean it. Turning the handle on the right side of the filtration system causes the water to be diverted through the system. Allow the water to flow through the filter for 5 minutes to remove any residue that may have built up within, allowing it to function more efficiently. After that, you can begin using the filter as soon as it is turned on
  • Nevertheless,
  • PUR faucet filters are effective for up to 100 gallons (380 L) of water, or approximately 3 months of continuous usage. Do not pass water through the filter that is hotter than 100 degrees Fahrenheit (38 degrees Celsius), as this might harm it.
  1. Warning: When you first use the new filter, the water may splutter or appear hazy, but this will improve as you continue to run water through the filter. Advertisement

  • Many PUR filtration systems are equipped with electrical lights that alert you when it is time to replace your filter. Unless you notice a flashing green light, you do not need to update your filter. If the light blinks yellow or red, it means that the filter needs to be replaced immediately.

Thank you for submitting a suggestion for consideration! Advertisement

  • It is not recommended to use water that is hotter than 82 degrees Fahrenheit (28 degrees Celsius) in a pitcher or hotter than 100 degrees Fahrenheit (38 degrees Celsius) from a faucet since it might harm the filter. Only use the filter with water that is already safe to drink because it will not eliminate germs or illness
  • Otherwise, use a different filter.

Chrome is the color of choice.

The Best Faucet-Mounted Water Filter

  • Who this is intended for
  • What we looked for and tried
  • Our choice is: Filtration System for the Pur Advanced Faucet The rivalry between the two teams

In addition to providing filtered water on demand, faucet-mounted water filters have the advantage of being a convenient alternative for families that use a lot of drinking water every day or for those who wish to cook or wash dishes with filtered water in addition to drinking it. As a result of the higher water pressure in the pipes, faucet-mount filters are more successful at removing pollutants than most pitcher filters, even our top selections in that category. Furthermore, the filters last longer than pitcher filters, often three months or 100 gallons as opposed to two months or 40 gallons with pitcher filters.

  1. They cannot be fitted on faucets that have integral pull-out sprayers; they can only be installed on classic one-piece faucets.
  2. Most filter installations feature a switch that allows you to switch between using the filter and using the standard tap.
  3. If these disadvantages dissuade you from using a faucet-mounted filter, an under-sink filter may be a more suitable alternative.
  4. Notably, neither faucet-mounted nor under-sink water filters dispense water as cold as you would obtain from a pitcher kept chilled in the refrigerator.
  5. First and foremost, you may not require one.
  6. The CCR lists every contaminant that has been tested for in your water supply, as well as the level of contamination found and whether or not that level meets Environmental Protection Agency standards.
  7. Secondly, there should be no expectation that a single faucet, pitcher, or under-sink filter can provide a lasting solution to a chronic water problem such as increased lead levels.

Finally, water that tests clean in municipal pipes can still get polluted as it travels to and through your house, as was the case in Flint, Michigan, and Newark, New Jersey, respectively.

If you want to be absolutely certain about what is in the water that comes out of your faucets, we recommend investing in a home water testing kit.

ANSI/NSF certification indicates that a filter has been tested in an approved laboratory and has been determined to decrease a specified pollutant to levels below the EPA’s maximum allowable concentration for drinking water.

In order to be certified, they must still decrease the challenge-solution pollutant to a level that is below the EPA’s permissible standard.

There are just a few other ANSI/NSF-certified faucet filters available in North America, and none have anything like the number of certifications that this one has.

We brought in a model from each of the companies.

The Complete model, which we examined, allows you to control the water flow between three different settings.

Pur has two alternative housing options: a horizontally oriented housing (found on theBasic, Advanced, and Bluetooth Ultimate models) and a vertically oriented housing (found on the Basic, Advanced, and Bluetooth Ultimate models) (theClassic).

The Basic and the MineralClear are the two types of filters produced by Pur.

We put the Advanced model, which has a MineralClear filter, through its paces.

Once the filters were installed, we utilized them for many months, noting any positive and bad elements of each, ranging from their basic looks to their simplicity of installation to their dependability and durability, as well as any perceived influence on water quality and flavor.

When the findings of this method were combined with the filters’ ANSI/NSF certifications, the results revealed a clear winner.

Our pick: Pur Advanced Faucet Filtration System

Our pick

This is our top option for faucet-mounted filters: thePur Advanced Faucet Filtration System (Pur). It has been certified by ANSI/NSF to reduce, to levels below EPA limits, 71 contaminants in drinking water, including lead, mercury, multiple pesticides and industrial chemicals, and a dozen so-called emerging compounds of EPA concern, including pharmaceuticals, bisphenol A (BPA), and estrone, a form of the human hormone estrogen, among others. That’s a significant improvement over its competitor from Brita, which has 56 approvals, none of which are for new or developing chemicals.

For the record, the Pur, in addition to filtering the 71 certified contaminants, has also maintained its ability to improve the taste and smell of our Catskill tester’s sulfurous well water for several weeks after the whole house carbon-block filter that he normally relies on to control the issue stopped working.

The full list of pollutants for which the Pur faucet filters have been ANSI/NSF certified can be found in the owner’s handbook (PDF), and it includes several that you may already be thinking about, such as: toxic metals such as lead and mercury; a variety of volatile organic compounds (VOCs); a variety of pesticides, including 2,4-D; and 12 “emerging compounds,” which are increasingly showing up in the water supply and include the plastic additive BPA; the insect repellent DEET; and the widely used flame retardants TCPP and TCEP The filters have a three-month or 100-gallon capacity, and the housing includes a flowmeter so you’ll know when they’ve reached their capacity; a little LED on the housing changes from green to yellow (indicating that time is running out) to red when the filters have reached their capacity (time to replace).

  1. Installing the Pur Advanced is straightforward—but, once again, no faucet filter is compatible with faucets that include integrated pull-out sprayers.
  2. Pur offers a variety of adapters to accommodate the varied sizes and threading patterns found on most aerators on the market.
  3. The Pur Advanced faucet filter (and any other faucet filter) works by reversing a toggle on the housing, which sends water through the filter and out a separate dispenser, and then flipping it back the other way to send ordinary, unfiltered water out of the faucet.
  4. For starters, the filtered-water flow rate (0.52 gallon per minute) is lower than the standard faucet flow rate (normally about 2 gpm), so having the option to use the faucet itself when you need a lot of water quickly (filling a pot, for example, or cleaning the dishes) is convenient.
  5. You must also be cautious while switching to the filtering mode, as described below: In order to clean the pipes after pulling hot water from your faucet, turn the faucet to cold for a few seconds before continuing with the hot water.
  6. Photograph courtesy of Michael Murtaugh The Pur filter was able to withstand heavy usage without developing any difficulties, such as leakage, which was not the case with the Brita filter that we also tried, which was also successful.
  7. The filters reached their 100-gallon capacity in around six weeks, compared to the three-month rule of thumb recommended by Pur.

To that burden, our tester added frequent daily refilling of glasses and coffee pots. Something to keep in mind if your home consumes large amounts of water on a regular basis. Replacement filters are roughly $10 (Basic) or $11 (MineralClear) per filter, depending on the model.

Our pick

There are three different finishes available for the Pur Advanced model that we tested: polished chrome, brushed metallic gray, and a vibrant tropical blue dubbed seaglass. Each Advanced model is equipped with a MineralClear water filtration system. The otherwise identical Classic model is available in either black or white (and contains the Basic filter, which has the same ANSI/NSF certifications as the Standard filter). Our tester chose a chrome-finish Advanced because he liked the way it looked “almost deco,” but he was quick to point out that other finishes, such as the metallic gray version we photographed for this review, did not achieve the same result.

Despite the fact that our tester did not notice any difference, flavor enhancement is not as gimmicky as it may appear.

Flaws but not dealbreakers

It was determined by our tester that “the continual small pressure you apply to the filter’s valve in order to switch on the filtered water caused our faucet to start coming loose at its base on a few of occasions.” Another contributing aspect is that the beautiful chrome becomes filthy easily, so you’re always wiping it clean, which increases the amount of pressure on it.” he explained. When we saw it was happening, we just tightened the faucet base. I’m not sure if the same thing would happen with a better faucet, but it was a little irritation for us.

  • If the sink is shallow, for example, it may be difficult to get a glass beneath the spout if there is anything else in the sink basin.
  • Photograph courtesy of Michael Murtaugh We also put the Brita Complete Faucet Filtration System through its paces.
  • This also distinguishes it from Pur’s filters, which do not have the spray feature.
  • Pur’s faucet filters have a substantially higher number of ANSI/NSF certifications than the competition.
  • We discovered that the Brita dripped excessively throughout our testing, which resulted in a pink coating on the filter housing, which we believe to be caused by the bacterium Serratia marcescens, which is commonly found in moist sinks and showers.
  • Contrary to what the title on the Amazon product website says, the Waterdrop WD-FC-01 is only ANSI/NSF certified for chlorine reduction, as well as for taste and odor.
  • The same is true for the WD-FC-03 and WD-FC-06, which are quite similar but are made of stainless steel.

In addition, the Dupont’sWFFM100XCHandWFFM350XCHuse the same filter cartridge and are only certified for eight ANSI/NSF contaminants: chlorine, particle Class I, asbestos, lead, mercury, volatile organic compounds, cysts, and turbidity.

How to Replace PUR Water Filter Horizontal?

PUR provides a variety of water filtration devices, however when pollutants accumulate in the filters, the efficacy of the filters begins to deteriorate. Replace PUR water filter according to the filtration system that you’re using, as each system has its own set of requirements. Cleaning the new PUR filter into a dispenser or pitcher that you keep in your refrigerator should be done prior to screwing it onto the filter. For the systems that will be connected to the faucet in the future, you can easily remove the old filter and replace it with a new one by following the instructions on the package.

Why is it Important to Learn How to Replace PUR’s Water Filter?

If you follow these instructions, you should be able to replace the filter pitcher by yourself. It is critical to replace the pitcher’s water filter on a regular basis because it is an integral aspect of the product’s lifespan. The rationale behind this is self-explanatory. The sediments collected by the filters increase in size in direct proportion to the volume of filtered water used to collect them. When the old filters are no longer able to collect any further residues, such as lead, you will be forced to replace them with new ones.

You’ll want your pitcher to be performing at their highest level possible.

The greatest thing is that changing the filters only requires a few easy steps, which means that you can do it on your own without any assistance.

Method 1: Replace the Dispenser or the Pitcher Filter

Allow the replacement filter to soak for at least 15 minutes in a container filled with cold water before using it. Make sure that the new filter is placed in a container that is clean and has enough depth to completely immerse the filter. Allow 15 minutes after filling the container halfway with cold water to place the container aside. At this point, any remaining carbon from the filter will float to the surface and isolate, ensuring that it does not end up in your water while you are drinking it.

Filters can be damaged by using water that is hotter than 30 degrees Celsius (86 degrees Fahrenheit).

Step 2.

Rotate the filter counterclockwise to remove the old one and put in the new one. Remove the lid from the dispenser or pitcher and set it aside. Then you may pick up and take away the pour tray. This pour tray is a blue-colored plastic reservoir with a spout. To unhook the cylindrical filter, hold it by the bottom and twist it in the opposite direction of the clock. Remove the old filter by taking it out of the pour tray by the tip of the filter. If you change the filter before the pour tray is completely clear, it may be difficult to remove or the filter may spill.

Step 3.

Under the tap, rinse the new filter for a minimum of 10 seconds to remove any residue. When the filter has had enough time to soak, take it from the pot and place it below your faucet to use.

Allow cold water to flow through it and then twist the filter to completely clear it out. After 10-15 seconds, turn off the water supply and shake out any leftover waste in the filter, if any is present.

Step 4.

Cleaning the filter with hot water may cause it to get damaged, so be careful! The filter should be inserted into the pour tray in a clockwise manner to ensure that it is well covered. Push the long, cylindrical piece of the filter all the way down into the pour tray, as far as it will go from the opening in the middle of the filter. While holding the filter by the rim, turn the filter in a clockwise manner until you hear it click into place. To guarantee that the filter does not pop out of the pour tray, gently press on the end of the filter.

If the filter does come out, it indicates that you did not complete the task properly.

Step 5.

If your dispenser is equipped with a reset button, push and hold it for about 5 seconds. Filter pitchers made by PUR, for example, have sensors that can detect when the filter needs to be updated. After replacing the filter, press and hold the Reset button for about 5 seconds to return to the previous state. A flashing green light will be seen on the lid of the device after the sensor has been reset. On older pitchers, it is possible that an electronic monitor will not be accessible.

Method 2: Replace the Faucet Filter

By unscrewing the water filter system from the faucet, you may clean it. Hold the system’s weight in place with the aid of your other hand to keep it from collapsing and crashing to the ground. Turning the plastic nut counterclockwise will allow the filter system to be removed from the faucet. After completely unscrewing the system, carefully move it away from the faucet and place it on a kitchen surface or a towel to catch any drips. It is conceivable that water may pour out of the faucet as you are going through this process.

If it won’t unscrew, simply grab it by the handle from the faucet.

Step 2.

To remove the old filter, first open the top cover of the system by twisting it open. The filtering system should be set up in such a manner that the cylindrical end of the cylinder faces up. Remove the top of the cylinder by rotating it counterclockwise, and then set it away for later use. Remove the old filter from the filtration system and toss it in the trash when it has been removed. The top cover is usually put on the opposite end of the water spout from where the water is being dispensed.

Step 3.

Placing the new filter directly within the filtration system and securing the lid will ensure that it is properly protected. Please bear in mind that the filter’s narrower end is positioned at the bottom of the container and that the mark is pointing up. Position the filter in the system such that there is only a little amount of space available. Replacing the top lid with a screw over the filter will keep it protected from damage.

Step 4.

Reattach your filtration system to the faucet one more to complete the cycle. Tighten the system’s grip on the faucet’s base. If the threadings are not perfectly horizontal, the seal will be compromised, and this will prevent that from happening. Using a clockwise rotation, tighten the locking nut on the faucet until it feels hand-tight to the touch.

Turn on the water supply and look for any leaks or drips along the seam line. If the filtration system does not screw on, align it with the faucet and use considerable pressure to snap it on if it does not screw on.

Step 5.

Allow for a thorough 5 minutes of circulation of cold water through the system. In order to rotate the water within the filter, turn the handle towards the right end of the system. Allowing the water to circulate through the system will eliminate any residue and increase its overall efficiency. After that, you will be able to utilize your filter immediately after turning it on. For instructions on replacing the PURfaucet water filter, please see the video below.


Allow the cold water to circulate through the system for a minimum of 5 minutes before flushing. In order to rotate the water within the filter, twist the handle towards the right end of the system. Allowing the water to circulate through the system will eliminate any residue and enhance its overall operation. As a result, you will be able to utilize your filter immediately after activating it. For instructions on replacing the PURfaucet water filter, please see the video below:

Frequently Asked Questions (FAQs)

It is recommended that you do not use water that is hotter than 28°C (82°F) in the pitcher since it may cause damage to the water filter. The temperature of the water coming out of the faucet must not be more than 38°C or 100°F.

How would I know when to change the filter?

The majority of the water filtration systems that the firm sells are equipped with electronic lighting. These assist in determining whether it is appropriate to change the filter. When the indicator blinks green, it indicates that the filter does not need to be changed at this time. However, if you see a flashing red or yellow light, it is time to change the bulb.

Will the filter remove bacteria?

No, the filter is not capable of removing any type of illness or germs. In order to avoid this, you must only use water that is already safe and suitable for drinking.

12 Reasons Why Your PUR Water Filter Is Leaking – And How To Fix It

It has been demonstrated that PUR faucet filters and filter pitchers can filter out more than 70 pollutants, including lead and mercury. It is possible, however, that they will leak under certain conditions. PUR water filters may leak as a result of improper installation, a filter that is too loose or too tight, hot water damage, debris, or an adapter that is incompatible with the filter. Leaks can also be caused by an ill-fitting O-ring, a loose valve, an inappropriate pouring technique, or a broken filter.

Types of PUR Water Filters

Here’s a short glance at the many PUR faucet filters and filter pitchers that are now available. This page is intended for those who utilize the filters listed below. Filters for faucets:

  • Faucet Filtration Systems from PUR include the PUR Basic Faucet Filtration System, the PUR Classic Faucet Filtration System, the PUR Advanced Faucet Filtration System with MineralClear filter, and the PUR Bluetooth Ultimate Faucet Filtration System.

Pitchers for Filtering:

  • Among the products available are the PUR Basic 7-Cup Pitcher, the PUR Classic 11-Cup Pitcher with LED, the PUR Classic 18-Cup Dispenser, and the PUR Classic 18-Cup Pitcher with LED.

12 Reasons Why Your PUR Water Filter Is Leaking

Probably the most prevalent cause of a water leak is improper installation. Make sure there are no leaks by following the manufacturer’s instructions for your individual filter. Listed below is a step-by-step guide on how to properly install a PUR faucet filter and PUR filter pitcher. For a PUR faucet filter, follow these steps:

  • The aerator and washer should be removed from your faucet. If the aerator does not come off easily, you can use a rubber jar opener to pry it off. Locate the adapter in the PUR box that corresponds to your tap (see the next section for further information on adapters)
  • Tighten your adapter and make sure the washer is in place. Remove the device’s rear cover by twisting it off and inserting the filter inside. Check to see that the filter is centered and that the O-ring is in good working order. The filter will only be lightly fitted
  • Replace the rear cover with a new one. Depending on the type of your faucet filter, you may be able to attach the device to the tap with a single click
  • However, this is not always the case. Maintaining the level of the device on the tap will help it to install faster if your filter does not enable one-click installation. Maintain a level position for the filter and ensure that the PUR logo is facing you before tightening the mounting screw by rotating it counterclockwise. When the device is successfully installed, you will hear a ‘click’ sound.

For a filter pitcher, use the following formula:

  • Soak the filter in water for 15 minutes
  • Wash the pitcher and dispenser with soapy water and rinse it well
  • Pour cold running tap water over the filter and hold it there for 15 seconds. Invert the filter and place it in the pour tray, then draw the filter down. Twist it in the opposite direction of the clock to form a secure seal. As the filter is locked into place, you will hear a clicking sound.

2. Filter Not Tight Enough

If your PURfaucet filter has not been coiled firmly enough so that it ‘clicks’ into place, the water may seep around the filter and into the sink or bathtub. It must be snapped into position in order to provide effective filtration. It is possible that unfiltered water will seep into the filtered water reservoir in your PURfilter pitcher, if the filter is not sufficiently tight. Remove the filter and reapply it to correct the situation. You only need to turn it counter-clockwise till you hear the click sound.

3. How Water Damage

Temperature-related damage to your filter might cause it to leak or enable unfiltered water to get through. Due to the fact that the temperature of the water has an effect on both the filtering agent and filter weave inside the cartridge, this is the case. Thermally activated pollutants such as chlorine may be released throughout the process, which is a concern. PUR recommended that you never use hot water to flush out your filter. For PUR faucet filters, do not use water that is hotter than 100 degrees Fahrenheit (38 degrees Celsius).

4. Debris In The Filter Housing Area

If the filter housing area becomes blocked with debris, it may prevent water from flowing properly and create leaks. When dealing with devices that have a threaded housing area for their cartridges, this issue is very prevalent. The debris becomes entangled in the thread and causes leaks to occur. Remove the filter from your faucet’s filter housing to clean the area around it. To empty a filter pitcher, unscrew the pitcher’s lid and carefully remove the filter cartridge. Scrub the housing with soapy water and a toothbrush until all of the dirt has been removed from the surface.

After completely drying the housing, run it under water to remove any soapy residue from the surface.

To remove the cartridge from your filter pitcher, shake it a lot until you hear the grains inside the cartridge shift. After washing the housing, put it back in place. This will also improve the flow of water.

5. Lever Not Closing Properly

If the leak originates from the place where the faucet filter’s on/off lever meets the faucet, remove the device from the faucet and reinstall it. Remove the device by rotating the threaded mounting nut counter-clockwise until it is no longer visible. Remove the mount cover and twist the filter cartridge into place when it has been installed. Keep in mind that the device should stay horizontal during the installation procedure and that the PUR logo should be facing you. Then, with strong pressure on the lever, turn it on and off a couple of times.

6. Incompatible Adapter

Your PUR faucet filter comes with a set of adapters and washers, which you may use to install it. When you use the incorrect adapter with your faucet, you may have water leakage at the junction between your tap and filter device. In some cases, an adapter for externally threaded faucets, an adapter for internally threaded faucets, or no external adapter at all may be required depending on your plumbing fittings. Install your faucet filter without the need of an adaptor and see how it works. If it doesn’t work, you can try one of the adapters that have been given.

  • PUR also supplies a variety of other adapters.
  • The black rubber washer should be inserted into the threaded end of the adapter to provide a secure fit.
  • It is not necessary to use pliers or other tools to secure the adaptor.

7. O-Ring Problems

It is a rubber or plastic ring that is fastened to the filter cartridge and prevents the filter cartridge from moving. Its purpose is to seal a plumbing junction, preventing any air or water from escaping through the joint. O-rings that have been wrongly installed, on the other hand, might cause your filter to leak. Each faucet filter cartridge is packaged with an O-ring to ensure proper sealing. Once the cartridge has been removed, check to be that the O-ring is securely in place before threading it around the faucet.

If you suspect a defective O-ring in a cartridge that is only a few months old, you can purchase a replacement ring online (after specifying the model and dimensions of your cartridge).

8. Filter Too Tight

It is a rubber or plastic ring that is fastened to the filter cartridge and prevents the filter cartridge from rotating. When used to seal a plumbing junction, it is intended to ensure that neither air nor water may escape through the joint. Your filter, on the other hand, may leak if your O-rings are not properly secured. O-rings are included with the purchase of each faucet filter cartridge. Make sure the O-ring is tightly in place before threading it around the faucet once it has been removed.

A replacement O-ring can be purchased online in the event that an O-ring in a relatively recent cartridge is suspicious (after specifying the model and dimensions of your cartridge).

It may be necessary to change your cartridge altogether if your cartridge is outdated and close to its expiration date.

9. Incorrect Pouring Method

This applies to the pitcher with the PUR filter. If you notice that unfiltered water is leaking out of the pouring tray as you tip it to pour, you may need to adjust your pouring method. Make certain that the pour tray has been completely drained before pouring filtered water from the pitcher into the sink. As a result, there will be no spills or mixing of filtered and unfiltered water.

  • Always flush the filter before using it for the first time. Using cold water in the filtered position for 5 seconds before each usage will help maintain the faucet filter’s effectiveness.
