WD-M6H delivers instant hot water at perfect temps: 113°F for formula, 185°F tea, 199°F coffee, 203°F oatmeal.
The WD-M6SL adds beneficial minerals such as K⁺, Ca²⁺, Na⁺, and Mg²⁺, which lightly alkalize the water and help enhance the flavor, making it suitable for daily drinking and cooking.
Enriched with K⁺, Ca²⁺, Na⁺, Mg²⁺, Sr²⁺, Zn²⁺, and H₄SiO₄, this system delivers natural-tasting mineral water, hot or cold, for the whole family.
All M6 models provide reliable RO filtration, user-friendly operation, safe drinking water, consistent performance, and NSF/ANSI 58 & 372 certified.
The filter features a 0.0001μm RO membrane and LED Function. It reduces microplastics, TDS, PFOA, PFOS, nitrate, fluoride, lead, and more, providing you with healthy water.
This system has a 185oz tank (135oz tap, 50oz waste) with a 3:1 pure-to-drain ratio, keeping water fully separate for safe use.
Our 40oz detachable glass pitcher helps prevent chemical harm. It's perfect for storing in the fridge, cooking, or pouring water for pets. The glass pitcher is from the Maxblue brand.
Smart voice alerts let you know when to replace filters, refill or empty the tank, and guide first-time setup easily.

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.
The Waterdrop X12 is a high-capacity tankless under-sink system from one of the best-known makers of reverse osmosis filters. Practically speaking, the high daily capacity allows the X12 to deliver water more quickly than lower-capacity systems when you open the faucet.
