Media Attention

It also has a remineralization feature, that packs in all the minerals you’d usually find in a bottle of mineral water. It is the perfect solution for families looking for the benefits of bottled water, without the extra cost and plastic waste.

The water filtration system has an efficient 3:1 water ratio that helps to conserve water resources. (By comparison, other tankless RO water-to-wastewater ratios are typically around 1.5:1 or 2:1.).

This system takes it a step further with UV sterilization, a built-in TDS meter on the faucet itself, and a remineralization cartridge to ensure the outflow is a perfectly alkaline 7.5 pH.

While most point-of-use RO filters service one faucet, the X12 Pro also provides filtered water to your dishwasher, your sink's cold-water supply, or an ice maker. You could even filter water for a bidet, if you're willing to do the plumbing.

Between the smart faucet, balanced pH, UV sterilization and sleek design, the Waterdrop Filter X12 feels like the future of home hydration.
