DE Pool Filters

Diatomaceous earth pool filters offer the best filtration of all pool filter types. DE filters outperform sand and cartridge filters because they're able to filter debris as small as 3 microns! Your water will be clearer, and you may be able to use fewer chemicals and run the pump less.

Diatomaceous earth pool filters are highly effective in cleaning and clearing your pool water. DE is a porous powder with microscopic openings, which allow water to pass through but prevents bacteria and particles as small as 3 microns. This makes them the most effective type of pool filter on the market. Like most pool filters, DE filters use a pressure gauge to indicate that they require backwashing to prevent them from becoming clogged. DE swimming pool filters also need to have their powder replenished from time to time, especially after backwashing. When you're through backwashing a DE filter, a new application of DE filter powder is added to the filter by pouring it directly into the skimmer. To keep your DE pool filter working properly, an annual breakdown is necessary to thoroughly clean the DE filter grids. Looking for maintenance supplies? Pool Center also carries DE powder, replacement filter grids and other DE filter parts.
