The Waterdrop WD-M6CG countertop reverse osmosis system features an 8-stage filtration process with a 0.0001μm RO membrane, effectively reducing TDS, PFOA, PFOS, nitrate, fluoride, arsenic, lead, and more, and is tested by a third-party laboratory. It quickly heats or cools water to 59℉ or 203℉, with a Favorite Mode to save preferred temperature and volume settings. The system infuses essential minerals like K⁺, Ca²⁺, Na⁺, Mg²⁺, Sr²⁺, and Zn²⁺ for a balanced taste. It includes a large 185oz tank with separate 135oz tap and 50oz waste water compartments, maintaining a 3:1 pure-to-drain ratio. Equipped with smart touch controls, an NFC one-tap guide, and a detachable 40oz glass pitcher, it offers installation-free convenience for kitchens, offices, or RVs. | Waterdrop | | M6CG Cold and Hot Reverse Osmosis System Countertop Water Filter, 8-Stage Mineralization, EXTRA M6RFG Filter | Black | Best Buy
