Filtering with diatomaceous earth (D.E.) gives you water that really sparkles. Thats 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 cant be seen individually, collectively they greatly affect water clarity.
Heres why diatomaceous earth 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 cant.
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.
In addition to providing the clearest possible water, FNS Plus was also designed for easy maintenance and long-term reliability. So you can count on it to keep your pools water clean and crystal clear for years to come.

How a D.E. Filter Works:
When diatomaceous earth (D.E.) is introduced into the filter system, it coats the filter cloth. As water passes over the filter grids, the D.E. particles capture even the smallest suspended dirt particles. When cleaning is needed, the water flow is simply reversed.
