Our 3M™ Under Sink Reverse Osmosis Replacement Water Filter Cartridge 3MROP411 is a multi-stage 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, is considered to be the prefilter and reduces particulate, chlorine taste and odor and lead. 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. Features for the 3MRO401 and 3MRO501 systems include: 2.4 gallon/9.1 L storage tank, 0.5 gpm/1.9 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.

Our 3M™ Under Sink Reverse Osmosis Replacement Water Filter Cartridge 3MROP411 is easily changed via the SQC (Sanitary Quick Change) design. A simple quarter turn to release the cartridge and another quarter turn to install the replacement is all that’s needed, no mess with spilled water. Everything is self-contained in the cartridge. Also included in the system is a built-in shut-off valve that allows for changing the Sanitary Quick Change filters without shutting off the water supply.

To maximize system performance and efficiency, regularly scheduled maintenance including replacement of the membrane 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.
