The 3M 3MRO401 Reverse Osmosis Drinking Water System will provide you and your home with clean, great-tasting water through advanced RO filtration. This multi-stage filtration system rigorously filters out contaminants by running your water through four filters, including a sediment pre-filter (3MROP411), a GAC filter (3MROP412), the RO membrane module (3MROM413), and a carbon block post-filter (3MROP416). This efficient system can produce up to 18.95 gallons of clean, fresh water per day!


This eco-friendly system is powered by your residential line pressure, meaning no electricity is required to operate it! It also helps conserve water by automatically shutting down when the storage tank reaches capacity, and turns back on the refill. The compact 3MRO401 System is easily installed under the sink, and can be used with the included drinking water faucet for cooking and drinking water applications (designer faucets also available). Replacing your filters is easy and mess-free; simply twist them in or out of their place. This filtration system has been optimized for reduction of select volatile organic compounds, and is tested and certified against NSF/ANSI Standards 42, 53, and 58 for the reduction of substances specified in the performance data sheet.
