Perflex EC 65 DE Filter

Keep your pool water clean and clear with the Hayward Perflex EC65 Diatomaceous Earth (D.E.) pool filter. Engineered for dependable use on larger above-ground and semi-inground swimming pools, this system provides high-capacity filtration that removes fine particles from your water without the regular hassle of traditional backwashing.

Diatomaceous earth is a highly efficient filtration material. The Perflex EC65 removes microscopic debris, dust, and pollen as small as 1 to 2 microns, providing a deeper clean than standard sand or cartridge filters.

This filter features a patented Flex-Tube assembly paired with a built-in "Bump" handle. When dirt builds up and slows down your water flow, simply moving the bump handle up and down cleans the filter tubes uniformly. This reuses the active D.E. powder and extends the duration of your filtration cycle before you need to replace the media, saving you time and hundreds of gallons of treated pool water.

The main filter tank is injection-molded from high-strength thermoplastic to prevent corrosion and withstand continuous seasonal operation. It features an easy-access clamp assembly for internal maintenance and a self-venting design that automatically expels trapped air from the system.
