Reverse osmosis
The Waterdrop Filter X12 is a tankless reverse osmosis system that delivers up to 1200 GPD of purified water. Its 12-stage filtration, smart digital faucet, and alkaline remineralization ensure safe, great-tasting water for large households.
The Waterdrop Filter X12 reverse osmosis system is built for households that want a truly high-end approach to water filtration. It gives families a reliable way to maintain safe, healthy, and great-tasting water every day, pairing strong purification performance with the convenience of a fast, efficient under-sink system.
A high-speed system that keeps up with daily life
The X12 pushes out an impressive 1,200 gallons of clean water per day, dramatically reducing wait time when filling bottles, prepping meals, or keeping up with a household that never stops using the kitchen. Even at peak hours, the system maintains steady output, making it ideal for busy homes.
11-stage filtration with added alkaline remineralization
Despite the higher clean-water output, the X12 does not compromise on water purity. It pushes water through 11 filters, including a robust 0.0001 μm RO membrane, to remove TDS, PFOA, PFOS, chlorine, lead, and over 1,000 impurities usually found in tap water.
Even better, the system goes one step further by restoring beneficial minerals for balanced pH and better taste, resulting in not just cleaner water but healthier hydration.
A more efficient pure-to-drain ratio
Older RO systems are notorious for wasting water. Waterdrop Filter solves that with a 3:1 pure-to-drain ratio, which cuts down on waste and helps reduce long-term utility costs. You can save up to 1200% of precious water resources compared to traditional RO systems.
Smart monitoring at the faucet
The X12 comes with a digital faucet that shows water quality and filter status in real time. It can alert you when filters need changing and lets you quickly adjust settings like water volume.
The Waterdrop Filter X12 will be discounted to $899 this Black Friday, giving you a $400 savings off its list price.
