Our 3M™ 3MDW301 Under Sink Dedicated Faucet Water Filter System is engineered to deliver cleaner, clearer, better tasting drinking water by filtering out contaminants that affect taste, odor and safety. We include everything needed for most installations such as a polished chrome dedicated faucet, quick-connect fittings, an attached mounting bracket and tubing. Also included is a built-in shut-off valve that allows for changing the Sanitary Quick Change (SQC) filters without shutting off the water supply. The valve helps conserve water by turning off the water when the storage tank is full and turning it back on as needed, to refill the tank. The universal system design allows for use on both chlorinated (municipal) and non-chlorinated (well water) systems. Other features include:

0.75 gpm/2.839 lpm flow rate
1,000 gallon/3,785 liter capacity
25-125 psi/172-862 kPa pressure range
40-100°F/4.4-37.8°C temperature range

Form Meets Function
3M™ 3MDW301 Under Sink Dedicated Faucet Water Filter System adds a touch of class with our gracefully arched, contemporary styled decorative drinking water system faucet. We use only high grade, quality materials, such as polished chrome, lead-free brass, and merge it with high style to help bring cleaner, clearer better tasting drinking and cooking water from 3M.

To maximize system performance and efficiency, we recommend regularly scheduled maintenance combined with replacement of the filter cartridges (every 12 months) and membrane cartridge (every 24 to 36 months) or when water quality and/or reduction in water flow rates becomes an issue.
