The Waterdrop TSA under sink water filter system features 8-stage deep filtration with three filters to reduce PFAS, PFOA/PFOS, chlorine, fluoride, heavy metals, rust, and more, delivering cleaner, better-tasting water. Recommended by National Geographic, it has a compact, space-saving design with quick-connect fittings for easy DIY installation in 3 minutes and 3-second filter replacement. Built with durable, age-resistant materials, it passes rigorous pressure and durability tests to prevent leaks or cracks, while its upgraded filtration area minimizes clogging risks. With filter lifespans of up to 18 months, the TSA ensures long-lasting performance for municipal tap water, though it is not designed for well or hot water.
