Our 3M™ HF-S Replacement Filter Cartridges combine chlorine taste and odor reduction with sediment and scale reduction and provide protection from the harmful effects of chlorine corrosion and scale. The cartridges are sanitary by design, to help maintain food service best practices. Our innovative Sanitary Quick Change (SQC™) design is an industry first for this application and allows for fast and easy cartridge change-outs without having to contact the filter media or the need for a filter wrench. The 3M™ High Flow SQC is one of the industry's most advanced water filtration system features, making change-outs fast and with just a 1/4 turn to remove the old and replace the new, minimizing the possibility of leakage and contamination. 3M™ Water Filtration Products Replacement Filter Cartridge, Model HF90-S materials are FDA CRF-21 compliant.* Some HF-S filters are designed to be 99.99% effective at removing water-borne heterotrophic bacteria and cyst by membrane filtration. With built-in scale inhibition on some models, they also reduce the ability of calcium and magnesium to precipitate on the evaporator plates as hard scale.
