Water Factory SQC 4 Replacement Filters

The CUNO/WaterFactory 4 stage RO system by 3M uses sediment and GAC pre-filters to reduce chlorine, chlorine by-products and sediment before the membrane filters out impurities larger than .001 microns. The carbon block post filter treats for taste and odor. Be aware that 3M has started to update some of the older part numbers to part numbers starting with 3M but are the same as prior part numbers. You can find and order all your filters at once in our replacement kits below. For less expensive generic replacements, please look at our Omnipure CSM brand.
