The Vevor faucet mount water filter is designed to purify and soften tap water for cleaner, better-tasting water in your kitchen or bathroom. Its carbon fiber filtration helps reduce chlorine, lead, sediment, rust, fluoride, and other impurities while improving taste and odor. The filter features two water modes so you can quickly switch between purified water and regular tap water as needed. Its compact ABS construction fits most standard faucets and installs in minutes with the included adapters. This package includes one filter unit and three filters for convenient everyday use.
