Know before you buy
The system measures 18.2 inches deep, 6.25 inches wide, and 16.72 inches high. Its tankless design is specifically engineered to save space, but you should measure your cabinet height and depth to ensure there is enough clearance for the unit and plumbing connections.
Yes, the system requires an electrical connection to power the smart faucet, real-time TDS monitoring, and the high-flow pump. Ensure you have a standard power outlet available under your sink before installation.
The filters are rated for 2,200 gallons of usage. The system features a built-in filter change indicator on the faucet, which will alert you when it is time to swap them out, typically every 12 to 24 months depending on your local water quality and usage volume.
This ratio indicates that for every three gallons of purified water produced, only one gallon is sent to the drain. This is significantly more efficient than traditional reverse osmosis systems, which often waste much more water during the filtration process.
The X16 is designed for DIY installation and includes clear instructions for setup. However, if you are not comfortable working with under-sink plumbing or electrical connections, hiring a professional is recommended to ensure all seals are secure and the system is functioning correctly.
No, the X16 includes an 11-stage filtration process that remineralizes the water to achieve a balanced pH of 7.5±. This results in a crisp, refreshing taste that is more alkaline than standard distilled or plain RO water.
