Replacement Filter Cartridge, 3M Water Filtration Products, HF40-S

The cartridge comes with an O-ring seal that makes the installation easier, using just a twist! The HF40-S cartridge is efficient at reducing the taste and odor of chlorine, as well as removing sediment and preventing scaling. All this is possible because of the HF40-S's Propriety Inhibitor. The cartridge features a Sanitary Quick Change (SQC) system; preventing any contact with the filter media during the change-out, ensuring absolutely clean water. The HF40-S cartridge does not require any pre-installation. It is rated at 0.2 microns level, has a flow rate of 2.1 gpm, and a capacity of 25,000 gallons. The HF40-S, 56133-05, cartridge is NSF 42 certified and sets a high benchmark in the niche of water filter cartridges.
