A faucet mount drinking water system is a low cost, hassle-free way to filter the water coming into your kitchen. A quality faucet filter can remove sediment, chlorine, cysts, linden, asbestos, mercury, and other pollutants that may find their way into some tap water. You get clearer, better tasting water that doesn't smell like there is something desperately wrong with your plumbing. Which 9 out of 10 Americans think is a good thing. The only guy that doesn't is Daryl, and nothing pleases him.
