Pentek Gs-210ro-MF Inline Reverse Osmosis Post Filter - Hollow Fiber & Carbon | Pentair

The Pentek GS-210RO-MF is an inline reverse osmosis post filter that combines hollow fiber membrane technology with Pentair's Fiberdyne carbon media to deliver an added layer of protection after RO filtration. This dual-technology design reduces heterotrophic bacteria and chlorine, giving RO systems a final polish stage that goes beyond standard carbon-only post filters.

Each GS-210RO-MF cartridge is manufactured to meet Pentair's strict factory performance requirements prior to shipment, and the inline design simplifies retrofitting or upgrading existing RO systems without major plumbing changes. The cartridge is NSF/ANSI Standard 53 certified to reduce cysts such as Cryptosporidium and Giardia by mechanical means, adding meaningful protection to the final stage of drinking water treatment.

With 1/4" FNPT threaded connections, the GS-210RO-MF is designed for straightforward installation into compatible undersink RO systems as a post-filter upgrade or replacement.
