The Waterdrop X16 is the flagship of the X Series: an 11-stage tankless reverse osmosis system rated at 1600 GPD — enough continuous flow for large households, entertaining, and serious cooking. A built-in mineralizing stage adds back trace minerals for balanced, great-tasting water.

PP cotton and activated carbon pre-filtration protect a 0.0001-micron RO membrane that reduces PFAS, lead, fluoride, arsenic, chlorine, nitrates, heavy metals, and total dissolved solids.

Front-access twist-out filters and electronic life tracking keep maintenance simple.
