Moen now offers faucets treated with “Microban antimicrobial protection,” which the company says prevents bacterial growth on surfaces. Faucets treated with Microban also feature the company’s Spot Resist stainless finish, which is supposed to keep the surface clean-looking by resisting fingerprints and water spots. These finishes are available on the Ashville two-handle center-set bathroom faucet ($100) and the Walden single-handle kitchen faucet ($160).
