The 3M™ Under Sink Reverse Osmosis Replacement Water Filter Cartridge 3MROP412 is a carbon based reverse osmosis replacement water filter cartridge that is for use with the NSF certified 3MRO401 and 3MRO501 reverse osmosis systems.

This cartridge, as part of these systems, adds an additional level of chlorine taste and odor reduction. Our 3MRO401 and 3MRO501 systems install under the kitchen sink and deliver cleaner, clearer, better tasting drinking water through a dedicated drinking water faucet. These systems provide water filtration on demand for drinking water, coffee, tea, baby formula, etc. and for cooking purposes as well. Our universal system design allows for use on both chlorinated (municipal) and non-chlorinated (well water) systems.

3MRO401 and 3MRO501 Systems Features:

2.4 gallon/9.1 liter storage tank, 0.6 gpm/2.3 lpm flow rate, 18.95 gpd/71.7 lpd production rate (3MRO401), 36.78 gpd/139.2 lpd production rate (3MRO501), ¹/₄" push-in connection,
40 to 100 psi/276 to 689 kPa pressure range and 40 to 100 °F/4.4 to 37.8 °C temperature range.

To maximize system performance and efficiency, regularly scheduled maintenance including replacement of the filter cartridges at the required interval, at the rated capacity, or sooner if a reduction in water flow occurs is required. Filter life is dependent on actual use and incoming water quality.
