DE Pool Filters

Diatomaceous earth or DE swimming pool filters are another style pool filter. DE swimming pool filters are considered the highest quality filter because they filter to the finest micron.

DE water filters contain grids inside the filter housing. The diatomaceous earth is poured into the housing, where it coats the grids. The fossilized diatoms act as tiny sieves, filtering out microscopic particles. Diatomaceous earth can filter out debris as little as 5 microns, or 5/1,000 of a millimeter.
