UF-3 Water Filtration System
Three-Stage Under Counter Ultra Water Filtration System
Reduces harmful chemicals and odor in water by 99.8%
The Watts Premier UF-3 Water Filtration System utilizes three-stage filtration to ensure you get cleaner, healthier drinking water straight from the tap. In addition to reducing lead, chemicals, and chlorine taste and odor, the UF-3 uses Hollow-Fiber technology to trap and remove even the tiniest particles from your water. Featuring a patented space-saving design that is perfect for houses and apartments, the UF-3 can be installed in a matter of minutes. Capable of running at low water pressures, this system does not require a separate water holding tank, does not alter the pH of the water, and does not require electricity, allowing a continuous, on-demand supply of premium quality drinking water directly to your tap. Includes three pre-installed filters, a parts bag, and a brushed nickel top-mount, twist faucet.
