A porous powder consists of microscopic openings look like tiny sponges when magnified They are used to coat "grids" in the filter housing and act as tiny sieves allowing for the removal of debris as small as 1-2 microns.
Once the pressure rises, the filter is backwashed so that the caked media is sent to waste and the filter is then "recharged" with more D.E. powder.
Perflex D.E. filters clean pools fast, removing particles as small as two microns the first time through.
Its patented Flex-TubeTM design gives longer cycles between cleaning because the same D.E. filter powder is used over and over.
Plus, Perflex cleans without backwashing, saving hundreds of gallons of treated pool water.
An exceptional value as a replacement filter or for new pool installations.
