The Hayward EC65 Perflex Extended Cycle DE Inground Pool Filter sets the gold standard for pool water filtration. It efficiently removes particles as small as 2 microns on the first pass. Unlike other DE filters, the Hayward Perflex features patented Flex-Tube technology, which reuses the same D.E. media for extended performance. The convenient bump handle helps clean the Flex-Tubes by removing excess dirt and filter powder, allowing for longer periods between maintenance. Enjoy crystal-clear water with the superior filtration power of the Hayward EC65 Perflex filter.
