Product Description

Perflex extended-cycle diatomaceous earth (DE) filters provide superior water clarity and extended filter cleaning cycles without requiring backwashing.


  • Clean pools fast, removing particles as small as two microns the first time through.
  • Patented Flex-Tube design gives longer cycles between cleaning because the same D.E. filter powder is used over and over
  • Unique bump mechanism allows DE flex tubes to instantly and uniformly clean themselves of dirt and DE filter media
