FNS® Plus Filters

More Surface Area for Better Pool Filtration and Less Maintenance

FNS Plus Pool Filters are designed with curved grids to maximize filtration area. More filter area means better performance and longer periods between cleanings. The internal design has been refined to minimize flow restrictions and, therefore, requires minimal pumping power to achieve a needed flow rate. This vertical-grid, D.E. filter is made of fiberglass-reinforced polypropylene for superior strength and reliability.

Where to Buy

Watch Before Opening or Cleaning

Pentair FNS Plus Filters have a large filter area for increased dirt capacity, and if the pressure gauge shows that the system is running at 10 PSI higher than its starting pressure, it is time for a cleaning. To ensure your pool cartridge filter is clean, you'll need to watch this safety video and gather a few tools before diving in. Be sure to consult a pool professional before performing maintenance or attempting pool filter cleaning on your own, or call a servicer outright if you're unsure of how to clean a pool filter.
