The Waterdrop X8 Under-Sink Reverse Osmosis System provides fast, intelligent, and space-saving filtration for daily drinking and cooking. Tested and certified by IAPMO R&T against NSF/ANSI 42, 58, and 372, and tested by SGS, it uses 9-stage filtration with a 0.0001 μm RO membrane to help reduce chloride, lead, TDS, fluoride, PFOA, PFOS, sand, salt, unpleasant tastes, odors, and other impurities. With a capacity of up to 800 gallons per day and a 2:1 pure-to-drain ratio, it produces two cups of filtered water for every cup of wastewater. The smart faucet displays real-time TDS information, while the filter-life reminder indicates when replacement is needed. The RO filter can last up to 24 months, depending on water quality and usage. Its tankless design saves up to 70% of under-sink space, and filters can be replaced in about three seconds without tools. An electrical outlet is required beneath the sink, and faucet installation requires drilling the countertop.
