How to Clean a Paper Pool Filter

Maintaining a clean pool filter is an essential part of swimming pool maintenance. A clogged filter can reduce the efficiency of your pool's overall cleaning system and lead to unsanitary pool water. But how do you clean your paper pool filter? In this article, we'll walk you through five steps to help you clean your paper pool filter and keep your pool water crystal clear.

1. Turn Off Your Pool Pump

Before you start cleaning your paper pool filter, turn off your pool pump. This will ensure that no water is flowing through the filter during the cleaning process. If water is flowing through the filter, it can be challenging to clean it thoroughly. Turning off your pump will also prevent any accidents from occurring while you're working on the filter.

2. Open the Filter

Once your pool pump is turned off, it's time to open your filter. Paper pool filters typically come in two types: cartridge filters and DE (diatomaceous earth) filters. If you have a cartridge filter, remove the cartridge and set it aside. If you have a DE filter, remove the filter housing top and carefully remove the DE filter elements. Be careful not to damage the filter elements, as they are fragile and can be expensive to replace.

3. Clean the Filter Elements

Now that you've removed the filter elements from your paper pool filter, it's time to clean them thoroughly. You can use a garden hose to rinse them off, or you can soak them in a solution of equal parts water and muriatic acid for about 30 minutes. Muriatic acid is a powerful cleaning agent that can remove stubborn stains and buildup from your filter elements. Be sure to wear protective gloves and glasses when handling muriatic acid.

4. Rinse and Dry the Filter Elements

After you've cleaned your filter elements, rinse them off thoroughly with a garden hose. This will remove any remaining debris and cleaning solution. Once they're clean, let them dry completely before you reinstall them in your paper pool filter. It's important to let them dry completely to prevent mold and mildew from forming on the filter material.

5. Reinstall the Filter Elements and Turn On the Pump

Once your filter elements are clean and dry, it's time to reinstall them in your paper pool filter. Be sure to follow the manufacturer's instructions for reinstalling the filter elements, as this can vary depending on the type of filter you have. Once your filter elements are in place, turn on your pool pump and check for any leaks or other issues.


Cleaning your paper pool filter is an essential part of maintaining clean and sanitary pool water. By following these five steps, you can keep your filter clean and working efficiently. Be sure to clean your filter elements regularly to prevent clogs and other issues that can reduce the effectiveness of your pool's overall cleaning system. With a little effort and care, you can keep your pool water crystal clear and inviting for all your swimmers to enjoy.
