The Waterdrop 600 GPD-Alkaline Tankless Undersink Reverse Osmosis System is a powerhouse when it comes to filtration. It uses 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+
