More surface holds more dirt, so the filter runs longer between backwashes and cleanings. The internal flow path is refined to minimise restriction, so the pump needs less power to push the required flow, and that shows up as lower running costs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuilt to last on the pad\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe tank is chemical resistant polypropylene reinforced with fiberglass for strength.

Magnified, each grain looks like a tiny sponge, full of microscopic openings. Water passes through those openings but particles as small as two to five microns are trapped on the first pass. Inside the filter, the grids become coated with DE, and it is that filter cake that strains dirt, dust and algae out of the water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKeeping it clean\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLike a sand filter, a DE filter is cleaned when it gets dirty, either by backwashing or by regenerating and draining the clogged DE to the waste line.
