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.

Here's 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 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 fl ow 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 pool's water clean and crystal clear for years to come.

? Curved vertical grids provide maximum filter surface area for greater dirt-trapping capacity and longer periods between cleanings.
