Filtering with the Pentair FNS Plus DE Filter 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 filters are fiberglass reinforced polypropylene of advanced chemical resistant materials for superior strength and reliability. The top manifold design features the Service-Ease grid pack for convenient one-at-a-time grid servicing.
