Hayward DE Filters
Diatomaceous earth is a porous powder with microscopic openings
that when magnified look like tiny sponges. Clear water can pass through these
openings, but particles, as small as two to five microns, are trapped during the
first pass through the media. D.E. filters have internal elements that become
coated with D.E. It is this 'filter cake' that strains dirt, dust and algae from
the water.
Similar to sand filters, when D.E. filters become dirty, they are cleaned either
by backwashing, or regenerating and draining the clogged D.E. to the 'waste'
line. To restore filtration, a fresh 'charge' of D.E. is added to the filter.
For sparkling, clean pools; step up to Hayward D.E. filters.
Perflex Extended-Cycle D.E. filters clean pools
fast, removing particles as small as two microns 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.
