Pentair FNS Plus 24 Sq. Ft. DE Filter (valve not included) (180006)

FNS® Plus Fiberglass D.E. Filters are fiberglass reinforced polypropylene of advanced chemical resistant materials for superior strength and reliability. The top manifold design features the Service-Ease grid pack for convenient one-at-a-time grid servicing.

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 1,000 microns). Even though these particles can’t be seen individually, collectively they greatly affect water clarity.

Here’s why D.E. filters work so well. 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 filters have been designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. Our 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.
