Hayward Pro-Grid Inground Pool Filter DE3620
This is the finest filter media available! Sand will filter down to 20 microns, cartridge filters down to 10 microns while Diatomaceous earth filters down to 5 microns! The Hayward Pro-Grid Inground Pool Filter DE3620 includes many advanced features, including an innovative Fully Automatic Air Relief with a double seal, which eliminates the need to manually vent the filter tank after system start-up. It also prevents back draining during pump shutdown.
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. This filter can be added to in-ground pool kits sold by Pool Warehouse!
