Keeping your filter running properly is one of the best ways to maintain a clean and healthy swimming pool. When it’s working properly, a pool filter is able to remove organic wastes and contaminants, as well as dirt, debris, and algae. This not only keeps your water crystal clear and inviting for swimmers, but will also help to prevent bacteria and other harmful substances from building up in your pool. Pool filters come in all shapes and sizes, but the most common are Diatomaceous Earth (D.E.), and cartridge filters. Regardless of the type of filter you have, it will need to be routinely cleaned and thoroughly inspected to ensure that it is working correctly.
