Pentek GS-10 PRF – Final-Stage RO Carbon Polishing Filter

Pentek GS-10 PRF – Final-Stage RO Carbon Polishing Filter

Complete your Pentair RO system's filter service with the Pentek GS-10 PRF granulated activated carbon polishing filter. Used as the fourth and final filtration stage in the Pentair GRO-2550 system, this replacement cartridge gives RO-treated water a final carbon polish before drinking.

Its role is different from the stage 1 sediment prefilter, stage 2 carbon prefilter and stage 3 RO membrane: this is the finishing filter, intended to help improve the taste and odour of your drinking water.
