Hayward Perflex W3EC50AC 25 Sq Ft Above Ground Pool DE Filter

The Hayward W3EC50AC Perflex Extended-Cycle 25 Sq Ft D.E. Filter cleans pools fast while removing particles as small as one micron the first time through. Using its patented Flex-Tube design, the Perflex gives longer cycles between cleaning because the same D.E. filter powder is used over and over. On top of that, the Perflex cleans without backwashing, saving hundreds of gallons of treated pool water. This filter is an exceptional value as a replacement filter or for new pool installations.
