Filter contaminants such as lead and chloroform, along with the taste of chlorine, from your tap water with a water-filtering pitcher or a faucet-mounted system. You'll also save money over buying bottled water, and the energy used -- and the pollution created -- to produce, ship, and dispose of all those plastic containers. Try the Brita Deluxe Pitcher (shown; Target.com, $24.99). Other models include the PUR Ultimate and the Shaklee Perfect pitchers. Faucet-mounted filters ($20 to $60 at home centers) are easy to install; they simply screw onto the faucet, and a valve lets you choose to bypass the filter (for example, when washing dishes).
