EasyClean DE Pool Filter by Pentair Aquatic Systems.
Diatomaceous Earth (DE) is proven to be the most effective filtering medium for removing microscopic particles as small as five microns (which are invisible to the naked eye). With many pores and sharp corners, DE pool filters do a superb job of trapping this tiny dirt and debris. Thanks to its design, the EasyClean automatic regeneration filter makes it even easier to enjoy the added water clarity that only DE media can deliver. It's the simple, trouble-free, and highly effective pool filter.
Features of the EasyClean DE pool filter include:
EasyClean's coated DE cartridge traps dirt and debris. As the build-up on the cartridge element grows heavier, DE media and trapped particles can fall from the filter cartridge and settle at the bottom of the housing when the pool pump shuts off. Once of the pump switches back on, much of the fallen DE media rises again and embeds itself back onto the filter cartridge while the debris stays behind. This automatic regeneration delivers maximum cleaning performance without the need to manually clean the cartridge nearly as often.
