The 3MRO401 Reverse Osmosis Drinking Water Filtration System helps provide cleaner, better tasting water through reverse osmosis filtration. The 3MRO401 offers multi-stage filtration, incorporating separate sediment and chlorine taste & odor filters, a sanitary, encapsulated reverse osmosis membrane, and a 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 when water is drawn from the tank. Replacement filters are easy to change - twist on, twist off, no mess.

The system is ready to use, shipping with a faucet, storage tank, reverse osmosis membrane, sediment filter pre-filter, granular carbon filter, and carbon-block post-filter.
