The 3M Aqua-Pure 3MRO301 Under Sink Water Filter System 04-04506 is a reverse osmosis, Level 1 system. The 3MRO301 features a micron rating of 5 that is ideal for reducing chlorine taste and odor, sediment/particulate, arsenic, barium, cadmium, chromium, copper, radium, selenium, turbidity, TDS, and lead. Built with a space-saving design for easy installation, the system's cartridges are also easy to install and remove. The 3MRO301 also comes with a dedicated faucet that adds additional performance compared to full flow and dedicated faucet systems. Besides delivering great tasting water, the 3MRO301 saves water, as it shuts down when storage tank is full and turns back on to refill the tank.

Note: System tested and certified by NSF International against NSF/ANSI Standard 42 and 58 for the reduction of claims specified on the Performance Data Sheet.
