Keeping your pool filter clean is essential to maintaining the health and safety of your pool. A dirty pool filter can lead to an increase in bacteria, algae, and other harmful organisms, which can lead to a variety of health problems for swimmers. In addition, a dirty pool filter can cause your pool water to become cloudy and unappealing, which can discourage people from using it.

The frequency at which you need to clean your cartridge pool filter will depend on a variety of factors. Some of the most significant factors include the size of your pool, the number of swimmers using it, and the level of debris that enters the pool. In general, larger pools with more swimmers and more debris will require more frequent filter cleanings.
