Watch how the world's best-selling under-sink RO system fits, works, and performs.
A high-flow tankless design delivers 600 gallons of pure water per day — fast enough to fill a glass in seconds and keep a busy household supplied, with no bulky pressure tank under the sink.
An industry-leading 2:1 drain ratio means far less water wasted than conventional RO systems — better for your bills and the environment, without compromising purity.
Independently certified to NSF/ANSI 42, 53, 58 & 372 — covering chlorine & taste (42), health-effect VOCs (53), reverse osmosis & TDS (58) and lead-free materials (372) — removing chlorine, heavy metals, PFAS, VOCs and emerging contaminants.
A dedicated remineralisation stage adds back calcium, magnesium and essential minerals after filtration — so your water isn't just pure, it tastes great and supports your health.
Full independent test results — exactly what the G3P600 removes, and to what standard.
