Waterdrop X12-Basic Reverse Osmosis System

The Waterdrop X12-Basic delivers the same 11-stage, 1200 GPD tankless reverse osmosis performance as the X12 in a streamlined package focused purely on purification. It is an under-sink system for households that want top-tier flow and contaminant reduction without extra dispensing features.

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

Tankless design saves cabinet space, and twist-out filters change in minutes.
