This under-sink water filtration solution delivers great tasting, filtered water right to your existing kitchen or bathroom faucet. 3M Under Sink Full Flow Water Filter System 3MFF100 is 3M’s state-of-the-art system with a capacity of up to 6,000 gallons. This system provides water filtration on demand for drinking (water, coffee, tea, baby formula) 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.The 3M Aqua-Pure 3MFF100 is easier to install than dedicated faucet under counter drinking water systems because it connects to your existing faucet. It does not require a separate faucet or any holes to be drilled into your countertop. It requires minimal under sink space. Filter change-outs takes a few minutes with the easy Sanitary Quick Change (SQC) design. The head assembly has a built-in shut-off valve that allows for changing the filter without shutting off the water supply. The universal system design allows for use on both chlorinated (municipal) and non-chlorinated (well water) systems. Includes a filter-head assembly, filter and mounting screws (installation requires some household tools and additional plumbing components. Please read user instructions). To maximize system performance and efficiency, replace every 12 months, at the rated capacity, or sooner if a noticeable reduction in flow occurs. Filter life is dependent on actual use and incoming water quality.
