Filters remove organic impurities such as dirt, leaves, grass, hair, and body oils from the water, keeping the pool sanitary, clear, and sparkling. The importance of proper swimming pool or spa filtration cannot be overstated. The reasons for filtration are obvious - clear water not only looks beautiful, but it is also necessary for health and safety reasons. Much of the material suspended in the water, derived from plant and animal sources provides food for bacteria and algae. It is these materials that must be removed if a pool or spa is to be maintained in a safe and sanitary condition.
