The Waterdrop G3P800 is a 10-stage tankless reverse osmosis system rated at 800 GPD — fast enough to fill a cup in about 6 seconds and keep a busy kitchen supplied all day. The tankless chassis frees up cabinet space and eliminates tank stagnation.

PP cotton and carbon-block pre-filtration protect a 0.0001-micron RO membrane that reduces PFAS, fluoride, lead, chromium, arsenic, iron, nitrates, chlorine, and chloramine, with post-carbon polishing for taste. An LED-equipped smart faucet reports live water quality.

Filter changes are front-access twist-outs — no tools, no disconnecting the unit.
