Expert-Backed Review Summary

The Waterdrop G2 Reverse Osmosis System brings advanced 7-stage purification into a compact, tankless under-sink design. Certified by NSF/ANSI 372 for lead-free materials, it uses a composite filter structure to effectively reduce TDS, PFAS, PFOA, PFOS, vinyl chloride, monobutyl ether, and other contaminants for cleaner, safer drinking water. Delivering up to 400 GPD, it fills a cup of purified water in just 12 seconds—far faster and more stable than traditional RO systems.

Its tankless design maximizes under-sink space, prevents secondary contamination, and integrates electrical and water circuits for safer, quieter, leak-resistant operation. With a highly efficient 1:1 pure-to-drain ratio, it cuts water waste by 300% compared to typical RO units. Installation takes under 30 minutes, and the twist-and-pull filters swap out in just three seconds. Two filters come included, making this system ready to use right out of the box.
