Your pool filter is an important part of the system that keeps your pool clean. Just as with other filters, it needs to be cleaned. How to clean it will depend on what kind of pool filter you have; it could be a cartridge, sand, or diatomaceous earth filter. Read on to learn the best way to clean pool filters. Keeping your pool filter clean will increase its useful life.

The cartridge filter is one of the easiest to clean. First, you need to make sure that you have everything you need to clean it, including the following:

Cartridge Filters: Cleaning the Filter
Once you have everything you need, cleaning the filter is a fairly straightforward process. Follow these steps to clean your filter:
- Turn your pool filter system off.
- Depressurize the system by removing the air. You will find an air relief valve on top of the filter (in most cases). Turn it slowly to remove the air from the system.
- Unhook the clamps on the side and remove the top of the filter now.
- Lift the filter straight out slowly and check it for any damage. You can also note how dirty it is. If you find rips or cracks, you will need to replace it altogether.
- You should start by spraying the cartridge with the hose. You can use the cleaning solution and the cleaning tool to make sure that you clean in the folds of the cartridge. If you need to soak the cartridge overnight, you can place it in the bucket with filter cleaning solution
- Check the o-ring on the tank that holds the filter. If it has any corrosion or looks worn out, you should replace it.
- Rinse the filter.
- Now you can put the filter back in the filter tank. Be gentle as you slide it right into place. You can put the lid back on the tank and clamp the sides.
- Turn the filter system back on. Open the air valve while you do this so you can make sure that you get all the air out of the system.
