COMPATIBILITY & APPLICATIONS
System Compatibility
The Omnipure CSM5621 is engineered to fit Water Factory Systems (WFS) and 3M Water Filtration reverse osmosis units that use the SQC quick-change format. It directly replaces CUNO part number 47-55710G2 and is compatible with CUNO 47-9298G2. This filter functions as the final polishing stage in under-sink RO systems, removing any residual chlorine taste or odor from the purified water after it exits the storage tank and before it reaches your dispensing faucet. Ideal for residential point-of-use drinking water systems requiring proprietary quick-change cartridges.
💧 The quarter-turn SQC design means no tools, no mess, and no direct contact with filter media during replacement. Mark your calendar when you install this filter so you stay on schedule with the 6-12 month service interval.
