Product Description

The Posi-Clear RP Cartridge Filter gives you everything you could ask for in a filter. It delivers top-of-the-line cartridge performance to keep pools sparkling clear, trapping particles as small as 20 microns (an average grain of sand is 1,000 microns). The new side entry design optimizes flow for nearly 50 percent greater efficiency than any other single cartridge filter on the market, earning it the Pentair® Eco Select® Brand for our most environmentally responsible equipment choices. Cleaning is a breeze - just open the top, remove the cartridge, and hose it off. And, its durable fiberglass tank ensures exceptionally long life. The Posi-Clear RP is the ultimate in convenience, and delivers refreshingly clear pool water.

I'm looking to replace an old sand filter. I have an 8,000 gallon in ground pool with a 1hp Max E Pro pump, would you recommend this filter over the star rite PLM 100? Thanks!

A  Answered on 2/6/2018 by InyoPools Product Specialist Lennox H.

Hi, Patrick. I will recommend the PLM Series filter over the Posi-Clear RP filter. The media that is used in the PLM filter holds more dirt, offers an overall better filtration.

Hi, LagyG. This filter can be used to filter a 35,000 gallon pool using a 1.5HP variable speed pump is the max flow rate does not exceed 100 GPM.
