The 3MRO401 Reverse Osmosis Drinking Water Filtration System helps provide cleaner, better tasting water through reverse osmosis filtration. 3MRO401, replaces the Water Factory SQC4, offering multi-stage filtration, incorporating separate sediment and chlorine taste & odor filters for excellent membrane module protection, a sanitary, encapsulated reverse osmosis membrane, and carbon block post-filter for superior flow from a dedicated faucet.

The 3MRO401 system is powered by residential line pressure - no electricity required. The system helps conserve water, shutting down when the storage tank is full and turning back on to refill the tank. Replacement filters are easy to change - twist on, twist off, no mess.
