Hayward Perflex EC65A Extended Cycle D.E. Pool Filter by Hayward

The exclusive Perflex Extended-Cycle gives you long filter cycles between cleaning – up to eight weeks depending on pool size and use. Because the same D.E. filter media is used over and over again, Perflex is a real work saver. And, it only takes minutes to extend the cycle.
Hayward Perflex Extended-Cycle Swimming Pool D.E. Filters clean swimming pools fast, removing particles as small as one micron the first time through. Its patented Flex-Tube 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. For sparkling, clean pools, step up to Perflex.
