It‘s important to keep your pool filter clean to ensure the water is clear and safe for swimming.

However, how often you need to clean the filter will depend on a few factors, such as the size of your pool and the type of filter you have.

Generally speaking, you should clean your pool filter at least once a week. But if you have a lot of debris in your pool, you may need to clean it more often.

And if you have a sand or DE filter, you‘ll need to backwash it every few weeks to remove the built–up dirt and grime.
