How To Clean A PUR Water Filter


Cleaning the PUR water filter is one of the crucial things you need to do to ensure the flow of purified and safe-to-drink water. Needless to say, doing it right is of great importance for your family’s health.

This article will show you the hassle-way free to clean your PUR filter, whether you have a dispenser, faucet mount, backpacking, or a refrigerator filter.

How to Clean a PUR Water Filter

No matter what type of filter you own, before you install it on your faucet or inside the dispenser or pitcher, it is highly recommended to clean it first. PUR recommends doing this so you can make your water filter even more effective at purifying your water.

But don’t worry. You don’t need to buy special equipment for this purpose. Cleaning the PUR filter couldn’t be simpler.

Follow these steps:

Step 1: If you already have an old filter that has been used for 3 months, replace with a new one. Here is the list of my favorite PUR water filters for your information.

While sometimes it is helpful for you to clean the old filter (in order to fix some issues such as problems with the light, etc.), the old filter should be disposed of after 2-3 months (or less if you use it extremely often or live in an area where the water is super polluted).

Step 2: Place the new filter in a glass and fill it with water. Pour in white vinegar that is equal to 1/3 of the amount of water.  The solution should go a few inches over the filter. Make sure that the filter is completely submerged.

Step 3: To get it cleaned thoroughly, the filter should be soaked for at least 5 minutes.

Step 4: Remove the filter from the water and run cold water directly over the filter’s top for at least 10-15 seconds.

Step 5: Let the filter air dry before re-installing it on your faucet or inside the pitcher.

If you and your family are enjoying clean water thanks to the PUR faucet filter, it may seem that cleaning the filter is somewhat a more complicated process. But even though there are certainly more parts involved here than that of a pitcher, the cleaning process is just as simple.

When replacing the filter or cleaning the debris from an old one, it is important to know that simply inserting the clean filter into its canister will not ensure purified water. If you have a PUR faucet filter you need to know how to clean the canister as well.

All right, let’s get your hands dirty. Follow these steps:

Step 1: Twist the cover off and remove the filter from the canister.

Step 2: If it is old, throw it away. Get the new filter and clean it properly, following above guidelines of how to clean a PUR water filter.

Step 3: Meanwhile, clean the canister thoroughly. Be careful to use something that is food and water safe for this purpose, and ensure that no dangerous chemicals involved.

You may go with mild dish soap, but I suggest vinegar instead.  Soak the canister in a bowl filled with 1 cup of vinegar and 3 cups of water for at least 3 minutes.

Step 4: Run cold water through it and get rid of any frit or debris with a sponge.

Step 5: Install the filter and canister onto your faucet. Run water for 5 minutes before drinking.

How to Clean a  PUR Water Filter Dispenser

The PUR filter dispenser is not only affordable, but it is also super convenient. It can be easily stored in your fridge and allow you to drink cold and purified water anytime. However, there is one downside to this useful appliance that it is prone to bacterial growth.

The upper part of the dispenser keeps the dirty water. However, over a certain time period, the bacteria present in the tap water can pile up inside your dispenser. That is why regular cleaning of the entire dispenser is highly recommended.

Step 1: Remove the old filter from the dispenser. Clean the new PUR water filter above guidelines of How to Clean a Pur Water Filter. Take the upper blue part of the dispenser off.

Step 2: Make a cleaning solution. You can either choose vinegar or bleach for this purpose. If using vinegar, use 3 parts of water and 1 part of white vinegar. If you are worried about the smell of the vinegar, add 1-2 tablespoons of lemon juice to neutralize the smell. If you want a more effective cleaning solution, mix a gallon (3.7 liters) of water with 2 to 3 teaspoons of bleach.

Step 3: Soak a sponge into the cleaning solution and clean the two parts of the dispenser (the blue part where you fill the tap water and the other one where the filtered water goes).

After wiping the dispenser, let it sit for about 2 minutes, but no longer than five.  The vinegar or bleach will sanitize and kill any bacteria.

The PUR backpacking filter has been a lifesaver for hikers. If you are an outdoor person and love to spend time in nature, then cleaning this PUR filter is something that you need to do regularly.

Step 1: Detach the glass fiber element and see if it needs to be replaced. If it refuses to pump then you should probably buy a new one. If it still works, then a good cleaning will do.

Step 2: Remove the handle of the pump and lubricate the O-ring with some silicone lubricant.

Step 3: Clean the main housing with water mixed with vinegar and let it sit for 2-3 minutes. Make sure to check the valve as dirt and grit are known to get wedged inside it.

Step 4: Reassemble the filter. Pump water-and-vinegar mix (the water-vinegar ratio is 3:1) through the filter if cleaning an old one, or use the guidelines of How to Clean a PUR Water Filter if it’s a new filter. Let it air dry.

How to Clean a PUR Refrigerator Water Filter

Usually found in the refrigerator’s base grill, the Pur refrigerator ice and water filters allow you to get rid of most of the contaminants from your fridge.

But although they are made to last for approximately 6 months, it is important to clean them regularly to ensure proper purification.

Now, let’s get down to the business. Follow these steps of how to clean a PUR refrigerator water filter:

Step 1: Remove the filter from your refrigerator and tap it over a bin to get rid of the piled-up dirt and excess debris.

Step 2: Make a cleaning solution of water and vinegar (3:1 ratio) and submerge the filter completely in it.

Alternatively, you can choose to soak it in a solution made of bleach (1 gallon or 3.7 liters of water mixed with 1-2 teaspoons bleach) or a cleaning mixture made of water and dish soap.

Let it soak for 5 minutes (if using bleach, 2 minutes are enough).

Step 3: Rinse well and run water through it for a few minutes. Make sure not to use hard water pressure to avoid damaging the filter.

Step 4: Let it air dry before pushing it back into place.


Cleaning the PUR water filter as well as its housing is an important step to fine water purification. A proper cleaning does not only sanitize and remove piled-up contaminants, but also improves the water flow and prevents clogging.

I clean my PUR filter once a week to keep those contaminants away from my glass. So I suggest you do the same.

Good luck with your cleaning! 🙂
