Pentair FNS Plus DE Filters

FNS® Plus Filters feature the same, superior curved grid design as the FNS®, but with a fiberglass reinforced polypropylene body for advanced chemical resistance and superior strength.

Filtering with diatomaceous earth (D.E.) gives you water that really sparkles. That’s because D.E. filters remove the tiniest of contaminants…particles as small as 5 microns. (An average grain of sand is 1000 microns!) Even though these particles can’t be seen individually, collectively they greatly affect water clarity.

Water passes through a series of D.E. coated grids. Under a microscope, D.E. looks like a collection of tiny sponges. And just like a sponge, water can pass through, but microscopic impurities like dirt, algae, and some forms of bacteria can’t. FNS® Plus D.E. Filters have been designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. Our exclusive internal design has been refined to minimize flow restrictions, and therefore requires minimal pumping power to achieve a needed flow rate. That means lower utility costs.
