About this Product
Product Information:FNS Plus filters are fiberglass reinforced polypropylene of advanced chemical resistant materials for superior strength and reliability. Filtering with diatomaceous earth (D.E.) gives you water that really sparkles, because D.E. filters remove the tiniest of contaminant, particles as small as 5 microns (An average grain of sand is 1000 microns.). Even though these particles cannot be seen individually, collectively they greatly affect water clarity.
The top manifold design of the FNS Plus D.E. Filters features the Service-Ease grid pack for convenient one-at-a-time grid servicing with with curved vertical grids to maximize filtration area, enabling better performance and longer periods between cleanings. Here is 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. Just like a sponge, water can pass through, but microscopic impurities like dirt, algae, and some forms of bacteria cannot.
The exclusive 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.
