What customers say
Users consistently praise the Waterdrop G3P600 Tankless RO System for its superior water quality and convenient tankless design. The purified water is frequently described as crisp, clean, and refreshing, a noticeable upgrade from tap or bottled options. Its space-saving under sink footprint and on-demand continuous flow are significant advantages. The system's high flow rate ensures quick filling of pitchers and pots.

Know before you buy
Not at all. The G3P600 features a high-speed 600 GPD flow rate, which provides a steady, instant stream of filtered water directly from the tap without the need for a bulky storage tank.
The system includes a smart faucet with a built-in filter life indicator. It monitors your usage and provides real-time alerts so you know exactly when to swap out the CF, CB, or RO filters.
This model features an efficient 2:1 pure-to-drain ratio. For every two cups of purified water produced, only one cup of water is sent to the drain, making it significantly more eco-friendly than traditional RO systems.
The G3P600 is designed for straightforward DIY installation. Most homeowners can complete the setup using standard tools, and the filter replacement process is tool-free and designed to be quick and mess-free.
The 8-stage filtration process is highly effective at reducing lead, chlorine, heavy metals, and cysts. It uses a 0.0001μm membrane to ensure your drinking water is clean and safe.
With dimensions of 18.11 x 5.67 x 17.73 inches, the tankless design is compact enough to fit comfortably under most standard kitchen sinks. We recommend measuring your available space before purchase to ensure a proper fit.
