Perflex^® Extended-Cycle by Hayward

Perflex® Extended-Cycle D.E. filters clean pools fast, removing particles as small as two microns the first time through. With a patented Flex-Tube design, the Perflex pool filter gives longer cycles between cleaning because the same D.E. filter powder is used over and over.

A D.E. filter is made from fossilized material called diatoms and can filter particles all the way down to 3-5 microns. This is pretty impressive because the width of a human hair typically ranges from 40-50 microns, so this filter will not have any issues cleaning out the smaller particles in your pool. For those who like to go late night swimming in a lighted pool, this is the filter you will want to use. Because this filter type can clean up even the smallest of particles, you will be more likely to see truly clear, crisp water being reflected in your pool. The D.E. filter uses a pressure gauge to indicate when it is time to backwash your product; typically when it reaches anything between 8-10 psi over its clean reading, you’ll know it time for a cleaning. While cleaning this filter, it is always a good idea to inspect for tears as any defect as such will call for a filter repair or replacement.
