Know before you buy
The unit measures 18.11" x 5.67" x 17.73". Because of its tankless design, it is significantly more compact than traditional RO systems, but you should measure your cabinet height and width to ensure there is enough clearance for the hoses and filter access.
Yes, the G3P600 requires a standard electrical outlet under your sink to power the internal pump and the smart monitoring features of the faucet.
Most traditional RO systems have a ratio of 1:3 or 1:4, meaning they waste a significant amount of water. The G3P600 is much more efficient, producing two gallons of purified water for every one gallon sent to the drain.
The system is designed for straightforward DIY installation, and most users find they can complete the setup in under an hour. You will need basic tools like a drill for the faucet hole and a wrench, but no specialized plumbing experience is required.
The system features a smart faucet with an integrated LED indicator. It provides real-time alerts when your filter life is running low, so you don't have to guess or track the usage manually.
The G3P600 is designed to operate within a pressure range of 14.5 to 87 psi. If your home's water pressure falls within this range, the internal booster pump will ensure a consistent 600 GPD flow rate.
