Cartridge Style Filter Overview
The crystal clarity of D.E. with cartridge convenience
Diatomaceous earth (D.E.) filters have always been recognized for providing the cleanest pool water. And
cartridge filters are popular for their convenience and easy-cleaning features. Now, Pentair has found a way
to bring you the best of both.
The new Quad D.E. Cartridge Filter features four easily accessible and removable cartridges. When water
passes through these cartridges, microscopic impurities like dirt, algae, and some forms of bacteria are filtered
out, giving you water that really sparkles.
The four-cartridge design greatly increases the filter’s internal surface area, meaning much greater cleaning
capacity per cycle without an increase in canister size. And cleaning couldn’t be easier. In fact, you have
three options...backwash and recharge like a traditional D.E. filter, remove and rinse off the cartridges, or
simply remove the lid, leave the cartridges in place, open the drain plug, and rinse.
You’ll even save money – water flows through the Quad D.E. so efficiently that with the correct pump you
use less energy.
The highest water clarity with the lowest amount of fuss
The Quad D.E. combination of diatomaceous earth (D.E.) in a convenient cartridge design means better
performance and longer periods between cleanings. Because D.E. removes the tiniest of contaminants –
particles as small as five microns – you can count on clean, crystal-clear water for years to come.
