Who This Water Filter Is Best For
A premium pick for families that want very fast tankless RO filtration, alkaline remineralization, strong exact-model testing, and smart faucet monitoring without stepping up to the X16's 1600 GPD capacity.
Choose the X12 when you want premium X-Series filtration and smart features but do not need the X16’s maximum 1600 GPD output.
