The Waterdrop K19-SFK Countertop Alkaline Reverse Osmosis Water Filter System is a powerhouse when it comes to filtration. It uses an 5-stage precision RO system with a 0.0001-micron membrane to remove a wide range of contaminants. According to the manufacturer and third-party testing, it effectively reduces:

Total Dissolved Solids (TDS)
PFOA and PFOS (forever chemicals)
Chlorine
Fluoride
Arsenic
Lead
Chromium-VI
Barium
Salt
Sediment
Microplastics
Odors and unpleasant tastes

It’s also NSF/ANSI 58 and 372 certified, meaning it meets rigorous standards for contaminant reduction and lead-free materials. Plus, it includes alkaline remineralization, which adds beneficial minerals back into the water for a smoother taste and a pH around 7.5+

MAIN PURPOSE

The Waterdrop K19-SFK Reverse Osmosis Water Filter is designed to deliver purified alkaline drinking water with ease and flexibility. Ideal for kitchens, offices, or RVs, this system enhances taste and hydration through advanced filtration and convenient countertop use.
