How Often Should You Clean Your Pool Filter Cartridge?

A clean pool is a happy pool, and one of the most important parts of keeping your pool clean is ensuring that your pool filter cartridge is clean and functioning properly. But how often should you clean your pool filter cartridge? Here are some helpful tips to keep your pool filter cartridge clean and your pool crystal clear.

What is a Pool Filter Cartridge?

A pool filter cartridge is an essential part of your swimming pool's filtration system. It's a replaceable filter element that traps dirt, leaves, and other debris from the water, keeping your pool clean and safe for swimming. The filter cartridge is typically made of spun polyester, which is designed to trap microscopic particles as small as 10 microns.

Why Should You Clean Your Pool Filter Cartridge?

A dirty pool filter cartridge can cause several problems that affect the overall quality of your pool water. A clogged filter can reduce the water flow to your pool pump, leading to lower efficiency and poor circulation that causes the pool's water to turn green. Additionally, a dirty filter cartridge can reduce the lifespan of your pool's pump and other essential pool equipment.

How Often Should You Clean Your Pool Filter Cartridge?

The frequency with which you should clean your pool filter cartridge depends on several factors, including the size of your pool, the pool filter cartridge's size, and the amount of use your pool gets. As a general rule, it is recommended to clean your pool filter cartridge every 4 to 6 weeks. However, if your pool gets a lot of use or an unusual amount of debris, you may need to clean your filter more frequently.

How to Clean Your Pool Filter Cartridge

Cleaning your pool filter cartridge doesn't have to be a complicated process. Here are some simple steps to follow to clean your pool filter cartridge:

1. Turn off the pool pump: Before you start cleaning your pool filter cartridge, make sure to turn off the pool pump and remove the filter cartridge from the filter housing.

2. Rinse the filter cartridge: Using a hose, rinse the filter cartridge with water to remove any loose debris or dirt. Make sure to rinse both the inside and outside of the filter cartridge thoroughly.

3. Soak the filter cartridge: After rinsing, soak the filter cartridge in a filter cleaner solution for approximately 12 hours. This will help to break down any stubborn dirt or debris that has stuck to the cartridge.

4. Rinse again: After soaking, rinse the filter cartridge thoroughly once again with a hose. Make sure to remove all traces of the filter cleaner solution.

5. Re-install the filter cartridge: Once clean, re-install the filter cartridge into its housing and restart the pool pump.


Keeping your pool filter cartridge clean is an essential part of maintaining a clean and healthy swimming pool. By cleaning your filter cartridge regularly, you can prolong the life of your pool equipment and ensure that your pool water stays crystal clear. Remember to follow the manufacturer's instructions for your specific pool filter cartridge, and if you're not sure about something, don't hesitate to ask a professional. Happy swimming!
