The Waterdrop 10UA Under Sink Water Filter System is engineered to provide safer, better-tasting water without the complexity of bulky filtration setups. Designed to connect directly to your kitchen faucet’s cold-water line, this under-counter system installs in as little as three minutes using twist-and-lock construction and push-to-connect fittings—no drilling required.
Certified to NSF/ANSI 42 standards, the Waterdrop 10UA effectively reduces chlorine, lead, PFAS (including PFOA and PFOS), and other contaminants responsible for bad taste and odor, while preserving essential minerals such as calcium, magnesium, and potassium. Unlike systems that strip water completely, this filtration process maintains mineral balance for healthier hydration.
An upgraded filtration area provides up to 20 times greater dirt adhesion capacity, improving filtration efficiency while significantly reducing the risk of clogging. Each filter delivers up to 12 months of service life when used with municipal water, making it a cost-effective solution for households, apartments, offices, RVs, and rental properties.
Replacement filters are affordable and easy to change, taking just seconds to swap out. The compact, modern design fits neatly under most sinks without sacrificing storage space. Backed by Waterdrop’s after-sales assistance and prorated performance support, the 10UA offers dependable performance and peace of mind for daily water needs.
