Waterdrop X Series Reverse Osmosis System, X12

The Waterdrop X12 is an 11-stage tankless reverse osmosis system built for households that want maximum output from an under-sink footprint. Its 1200 GPD flow rate fills a glass in seconds and keeps up with cooking, coffee, and refill bottles without a storage tank taking over the cabinet.

The multi-stage design combines PP cotton and activated carbon pre-filtration with a 0.0001-micron RO membrane and post-carbon polishing, reducing PFAS, lead, fluoride, arsenic, nitrates, chlorine, heavy metals, and total dissolved solids.

Filter changes are quick twist-out swaps, and the front panel tracks filter life so there is no guesswork.
