Quick Overview

The Pentair 180007 FNS Plus 36 Sq Ft DE Swimming Pool Filter gives pool owners an easy way to switch to the incredibly superior filtering abilities of diatomaceous earth. Filters using diatomaceous earth result in water that is cleaner and more clear than traditional sand and cartridge filters.

The FNS Plus has a corrosion resistant reinforced plastic casing allowing it to stand up to the harshest weather environments. The eight DE grids inside are curved to allow greater surface area for more effective filtering and each grid has integrated handles for easy removal. The efficient design of the FNS Plus uses large external fittings and low-restriction internal plumbing to maximize the efficiency of your pool pump. The FNS Plus can filter particles as small as 1 micron including dust and pollen giving your pool water purity that cartridge filters simply cannot match.
