Diatomaceous earth (D.E) filter DE filters are compact and filter out the smallest particles in comparison to sand and cartridge filters. The filter is backwashed similar to the sand filter, but unlike just backwashing alone, the filter always needs fresh DE powder added.
How does a DE filter system work?
The DE filter works by adding Diatomaceous Earth powder, which contains microscopic skeletons of diatoms, a type of algae, to the pool filter. The powder acts like a sponge and absorbs the dirt and debris particles that come through the pool filter and sifts them out using the skimmer box.
Are sand filters better than DE filters?
Sand filters are least effective but also the least expensive to buy and use. Cartridge filters are more effective but are more expensive to buy and use. DE filters are the most effective but are the most expensive to buy and use.
What is the purpose of DE in a pool filter?
When diatomaceous earth is introduced into the pool filter system, it coats the filter cloth. As water passes over the filter grids, the DE particles capture even the smallest suspended dirt particles. When cleaning is needed, the water flow is simply reversed.
What does DE filter mean?
A diatomaceous earth filter (DE filter) is composed of several grids that hold the diatomaceous earth powder. They are sometimes known in the business as “water polishers” since they are capable of filtering particles as small as three microns (in comparison, a grain of salt is about 90 microns in size).

Do not operate your filter pump without having the D.E. powder coating the grids, or you will see the filter pressure rise very quickly, and if left in this manner the grids can collapse or the fabric can become clogged or damaged. As the pressure gauge on a D.E. filter increases, flow rate decreases.
