Pentair FNS Plus Fiberglass D.E. Filter | 60 Sq. Ft. | EC-180009

The filter that delivers crystal clarity. 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). 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.

 

The culmination of 40 years of pool filter experience. FNS Plus filters have been designed with curved grids to maximize filtration area. Its 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. In addition to providing the clearest water possible, FNS Plus filters were also designed for easy maintenance and long-term reliability.
