The Pentair FNS Plus 48 Sq. Ft. D.E. Filter delivers superior water clarity, strength, and reliability for residential pools. Designed with a fiberglass-reinforced polypropylene tank, this filter is built to handle tough pool environments while resisting chemicals and corrosion. With 48 square feet of filtration area and a high-flow design, it provides powerful performance and crystal-clear results for pools of various sizes.
This filter uses diatomaceous earth (D.E.) media, known as the most effective pool filtration method, trapping particles as small as 5 microns. The large internal grid system allows maximum water flow while maintaining low operating pressure, extending the life of your pump and reducing energy costs.
Maintenance is made simple with a convenient top-mounted clamp ring, quick-access service cover, and easy-to-use drain port. Certified to NSF/ANSI standards, the Pentair FNS Plus ensures safety, reliability, and professional-grade performance.
