The Waterdrop G3P600 is one of the most popular tankless reverse osmosis systems on the market: 8 filtration stages, 600 GPD of flow, and a slim 18.1" x 5.7" x 17.7" chassis that leaves most of the under-sink cabinet usable.

PP cotton and carbon-block pre-filtration feed a 0.0001-micron RO membrane that reduces PFAS, fluoride, lead, chromium, arsenic, iron, nitrates, chlorine, and total dissolved solids, with post-carbon polishing for taste.

A smart faucet displays water quality in real time, and filter changes are tool-free twist-outs from the front of the unit.
