The Pentair FreeFlo cartridge filter is a low maintenance, easy-to-use and cost-effective cartridge filter for small to large sized swimming pools (20,000-100,000L).

The FreeFlo Cartridge filter range combines top-end filter performance with low maintenance.

FREEFLO cartridge filters feature large filter areas, which ensure even water distribution, peak filtration performance and longer filter cycles.

The dependable design uses special filter elements to capture tiny particles from your pool water; particles as small as 8 microns. (An average grain of beach sand is 1,000 microns!) Plus, cleaning is a breeze. Open the top, remove the cartridge element, hose it off, and the FreeFlo filter is ready to go to work again, cleaning your pool water.

The corrosion-resistant construction of FREEFLO cartridge filters provides long service life and durability. FREEFLO cartridge filters are capacity-matched with the Pentair range of pool pumps, forming a total pool filtration system built to last.
