The Casa Waterdrop X16 is a tankless reverse osmosis system that tucks under the sink and runs water through an 11-stage filtration process for cleaner drinking water at the tap. Its compact, tankless design frees up cabinet space and lends itself to a manageable DIY installation. A smart digital faucet displays filter status so you can keep an eye on upkeep at a glance. Built for steady household use, it delivers filtered water on demand without the bulk of a storage tank. Installation Manual Installation Video Questions on sizing, finishes, or installation?
