3M (3MROP411) Sediment Filter for 3MRO401 & 3MRO501 RO Drinking Water
3M 3MROP411 Sediment Pre-Filter Cartridge
The 3M 3MROP411 sediment filter is the first stage of defense in your 3M reverse osmosis system, capturing rust, silt, sand, and particulate down to 5 microns before they reach the RO membrane. This meltblown polypropylene cartridge uses a proprietary twist-lock design for tool-free replacement every 12 months, protecting downstream components and extending membrane life in 3MRO401 and 3MRO501 systems.
Filter Performance and Operating Parameters
| Model Number | 3MROP411 (also 3MROP411-20A) |
| Filter Type | Meltblown sediment pre-filter |
| Micron Rating | 5 micron nominal |
| Service Flow Rate | 0.6 GPM maximum |
| Operating Pressure | 40–125 psi |
| Temperature Range | 40–100°F (cold water only) |
| Replacement Interval | 12 months or as needed |
| Connection Type | Proprietary twist-lock (3M RO systems) |
| Contaminant Reduction | Sand, silt, dirt, rust, sediment, particulate |
Designed for 3M RO Systems
The 3MROP411 sediment filter is engineered exclusively for use in the 3M 3MRO401 and 3MRO501 reverse osmosis drinking water systems. This pre-filter cartridge is also compatible with legacy Cuno Water Factory SQC systems using the same proprietary housing (Cuno 47-55706G2). The twist-lock design ensures proper fit and sealing in 3M under-sink RO units installed in residential and light commercial applications. Not compatible with standard 10-inch or 20-inch universal housings.
3M maintains third-party NSF testing and certification standards across its residential water treatment product line, backing the 3MROP411 with the same engineering rigor applied to commercial filtration systems.
