Hayward Perflex D.E Filters


Though sand filters are still the most popular filters for swimming pool owners, the D.E Filters run a very close second. The D.E stands for Diatomaceous Earth. This is a powdery substance that has microscopic openings that act like tiny little sponges that work to remove bacteria, contaminants and germs from your swimming pool. The inside components of the D.E Filter have elements that are coated with D.E and they call this a filter cake because it will strain the dirt, dust, algae from the water.Hayward Perflex D.E Filters
