Pro-Grid™ Vertical Grid D.E. Filter


Serenity equips your pool with a Pro-Grid DE filtering system

What is DE? Diatomaceous earth is a porous powder with microscopic openings that when magnified look like tiny sponges. Clear water passes through these openings, but particles as small as 2 to 5 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. 

Pro-Grid™ vertical grid D.E. filters provide superior water clarity, efficient flow and large cleaning capacity for pools and spas of all types and sizes. Constructed with high-strength reinforced thermoplastic, Pro-Grid combines high-technology features and "service-ease" design for an unparalleled filtration value for both new pool and aftermarket installations.

In addition, Pro-Grid delivers low maintenance and dependable operation.
