The Waterdrop TSU-W Ultrafiltration Under Sink Water Filter System delivers clean, healthy water straight from your tap through a powerful 0.01-micron ultrafiltration membrane that removes 99.9% of bacteria, chlorine, PFOA, PFOS, and other contaminants. Its compact, space-saving design fits neatly under most sinks, while the integrated leak-proof waterway and NSF/ANSI 372 lead-free certified materials ensure long-term reliability and safety for your family.

Operating with zero wastewater and no electricity, the TSU-W is as eco-friendly as it is efficient — and with filter lifespans of up to 24 months (PP 6 months, CT 12 months, UF 24 months), you'll spend less time on maintenance and more time enjoying purified water. When it's time for a change, front-panel indicator lights and an audible beep alert you, and the twist-and-pull design makes filter swaps a one-step, tool-free process. Use more, save more — and never compromise on water quality again.
