When good, better or best isnÆt good enough

Filtering with diatomaceous earth (D.E.) results not just in clean water, but water that really sparkles. ThatÆs because D.E. filters remove particles so small, they are measured in micronsàparticles the human eye canÆt even detect but noticeably affect water clarity. DE filters remove the tiniest of contaminants for water thatÆs truly crystal clear.

D.E. filters not only filter better, they make your life easieràif two goals are met. First is to maximize the filtration area. More filter area means longer periods between cleanings. Second is to design a system that requires the least amount of pumping power to achieve a needed flow rate. Because lower pumping requirements mean lower utility costs.

ThatÆs why all Pentair D.E. filters feature curved grids to maximize surface area. ItÆs why their internal design has been refined to minimize flow restrictions. No wonder more than 2 million Pentair filters have been installed by pool professionals.

With the FNS Plus D.E. filter, youÆll enjoy sparkling clear water from the most effective filtration system you can buy. And because theyÆre designed to extend the time between cleanings, you spend more time enjoying your pool and less time maintaining it.
