How To Unclog A PUR Water Pitcher Filter?

The best way to unclog a PUR water pitcher filter is to shake it or first wash it with warm water from the bottom for at least 30 seconds, then rinse it with cold water. This will help remove any debris or buildup that may be causing the clog. If this doesn’t work, you may need to change your filter.

Disassembly: Empty the pitcher and remove the lid. Gently pull out the filter by rotating it counterclockwise from its slot. Remove any large pieces of debris from the filter before disassembling it further.

Cleaning: According to the manufacturer’s instructions first shake the filter cartridge if it doesn’t work then the second option is to place the filter upside down under running warm water. Flush the exit ports, if there is anything causing the blockage, remove it. Rinse the filter with cool running water until it is clean. Shake the filter one more time before replacing it in the pour tray.

Reassemble: Insert the filter back into the slot of the pitcher. Fill the top reservoir of the pitcher with cool tap water. Look at the draining speed of the filter if it works in your case or not.

Reason For Slow Flow Of PUR Water Filter

Clogged Filter

Clogged Filter: A clogged filter can reduce the flow rate and decrease pitcher capacity.

Air Bubbles: If the pitcher has been recently filled, trapped air bubbles in the filter can reduce the flow rate until they are released.

High Mineral Content In Water: Minerals such as calcium and magnesium can reduce the flow rate of PUR filters, so using filtered or distilled water can help.

The Filter Is Old: An older filter may not be performing optimally; replacing it with a new one can help.

Leaks: If any of the connections are loose, water can leak out and reduce the flow rate. Tightening the connections can help.

Incorrect Filter Installation: Improperly installed filters can cause inefficient flow, so always make sure that filters are properly inserted into their slots.

Presence Of Contaminants: Contaminants such as rust and sediment can reduce flow rate; using filtered or distilled water can help.

Preventative Measures To Avoid Clogging

Change The Filter Regularly

Change The Filter Regularly: Depending on the type of filter, it should be replaced every 2-3 months for optimal performance.

Clean The Pitcher And Lid: Regularly wiping down the exterior of the pitcher and lid can help keep them free from dirt and debris that can cause clogging.

Use Filtered Or Distilled Water: Filtered or distilled water is free from minerals and contaminants that can reduce the flow rate of a PUR filter.

Avoid Overfilling The Pitcher: Overfilling the reservoir can reduce the flow rate, so make sure to only fill it up to the fill line.

Avoid Using Hot Water: Hot water can damage the filter which can affect its efficiency.

Why is Purchasing a Water Filter Essential?

Water filters are essential for ensuring that your drinking water is clean and free of pollutants, chemicals, and other contaminants. They can also improve the taste and smell of your water. By removing chlorine from tap water, filters protect against long-term health risks due to over-exposure to it.

What Are The Benefits Of Unclogging A PUR Water Filter?

How Do I Know If I Need To Replace The Water Filter?

  • If your PUR water filter has not been replaced in over two months, it is time to replace the filter cartridge.
  • A single filter should filter over 100 gallons of water, depending on the quality of the municipal or well water you are using.
  • The filter indicator light will remind you when it is time to replace the filter and can often be found on the lid of the pitcher.

Why Is PUR Water Filter Blinking Red After Filter Change?

If your PUR water filter is blinking red after you have changed the filter, it means that the filter is not connected properly. Remove the filter and make sure that it is inserted all the way in securely. If not, insert it firmly until it clicks into place. Once it’s secured, press down on the top of the filter to activate the filter. Your light should turn green indicating that the filter is working properly.


Having a PUR water filter is essential for getting clean, safe drinking water. However, it is important to keep your filter in good condition by unclogging and regularly replacing it. Taking the time to clean out debris, sediment, and other contaminants can help extend the life of your filter and improve its performance. Understanding how the different components of the filter work and what could be causing a reduced flow rate can help you troubleshoot any issues more quickly. With the right maintenance, your PUR water filter will keep providing clean drinking water for a long time.
