Filtering with diatomaceous earth (D.E.) gives you water thatreally 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.
The 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. In addition to providing the clearest water possible, FNS Plus filters
were also designed for easy maintenance and long-term reliability. So, you can count on them to keep your pool's water clean and crystal clear for years to come.
