The Waterdrop K19-SFK is a 7-stage countertop reverse osmosis system with built-in remineralization — delivering purified water enriched with beneficial minerals for a naturally balanced taste. Certified to NSF/ANSI 42, 58 and 372, it reduces PFAS, lead, fluoride, arsenic, chlorine and dissolved contaminants at 75 GPD. No under-sink installation required — the K19-SFK connects to your faucet and sits on your countertop. The remineralization stage adds calcium and magnesium back to the RO-purified water. Replacement filter: WD-K19RF.
