Know before you buy
Not at all. The tankless design actually allows for a rapid 600 GPD flow rate, meaning you get a steady, instant stream of purified water without waiting for a tank to refill.
The system includes a smart faucet with an integrated LED indicator. It monitors your water quality and filter life in real-time, changing colors to alert you exactly when a replacement is needed.
The system is designed for a straightforward DIY installation that typically takes about 30 minutes. It fits standard under-sink configurations and comes with all necessary connection ports.
This ratio is highly efficient compared to traditional RO systems, which often waste much more water. For every two cups of purified water produced, only one cup is sent to the drain, making it a much more eco-friendly choice for your home.
The 0.0001μm RO membrane is highly effective at reducing up to 99% of common contaminants, including lead, PFAS, and chlorine. It is NSF/ANSI 42, 58, and 372 certified, ensuring it meets rigorous safety and performance standards.
Yes, because the system uses an internal pump to achieve its high flow rate and efficiency, it requires a standard electrical outlet under your sink for operation.
