3M Under Sink Full Flow Water Filter System 3MFF100 is 3M’s state-of-the-art drinking water system with a capacity of up to 6,000 gallons. This system provides water filtration on demand for drinking and for cooking purposes. It is NSF certified to reduce particulate, chlorine taste and odor, parasitic protozoan cysts, lead, and select volatile organic compounds (VOCs) such as benzene and p-Dichlorobenzene. A key feature of this water filter is that it is designed to flow at the rate of your faucet (up to 2.5 gallons per minute) - minimizing loss of water pressure commonly seen with using water filters. Advanced triple stage filtration process to help provide cleaner, clearer, better tasting drinking water. First stage nonwoven media captures the larger particles, then in the second stage, the pleated sub-micron membrane reduces particles as small as 0.2 micron, and finally, the carbon block reduces chlorine, taste, and odor and select VOCs that may be present in the drinking water. Filter change-outs take a few minutes with the easy Sanitary Quick Change (SQC) design.
