Pentair FreshPoint GRO-475 Reverse Osmosis System

The Pentair FreshPoint GRO-475 is a high-production 5-stage tankless reverse osmosis system rated at 475 gallons per day -- among the highest production rates in residential under-sink RO systems. The tankless design eliminates the pressurized storage tank and replaces it with a 1.8-liter buffer reservoir and a high-efficiency booster pump, delivering filtered water on demand at full kitchen faucet flow pressure rather than the reduced flow of tank-pressurized RO systems. Stage 1 is a polypropylene sediment pre-filter. Stage 2 and 3 are carbon block pre-filters protecting the RO membrane. Stage 4 is the 475 GPD TFC RO membrane (NSF/ANSI 58 certified). Stage 5 is a carbon post-filter for final taste polishing. NSF/ANSI 58 certification covers reduction of TDS, lead, nitrates, arsenic, fluoride, barium, radium, and other health contaminants. The LED display indicates filter life status for each stage. A dedicated chrome faucet is included.
