Fiberglass D.E. Filter
By Pentair Pool Products

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.

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 ow
restrictions, and therefore requires minimal pumping power
to achieve a needed 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.
