Waterdrop G3P800 review: specs, upkeep, and fit

The G3P800 is one of Waterdrop's prominent under sink reverse osmosis systems. Its main appeal is a tankless design with high published output and a smart faucet.

What Waterdrop publishes

Waterdrop lists the G3P800 with a smart display faucet, 800 GPD capacity, a 3:1 pure to drain ratio, and indoor use. Its current product comparison lists CF replacement at six months, CB at twelve months, and the RO filter at twenty four months.

Certification

Waterdrop lists the G3P800 with NSF/ANSI 42, 53, 58, and 372 certification references. When a specific contaminant is the reason you are buying a filter, check the current performance data and certification listing for the exact reduction claim.

Who is it for?

The G3P800 makes the most sense for someone who wants an under sink tankless system and values high output. It needs cabinet space, plumbing, and electricity, so renters or people who want a portable system may prefer a countertop design.
