AquaTru Carafe (AT100)
Pros
- Certified to NSF/ANSI 42, 53, 58, 372 and 401, including PFOA/PFOS
- Purified water touches only glass
- WaterFilterGuru's top-scoring countertop RO
- Lowest price among certified units
- Optional mineral filter adds minerals back
Cons
- Small capacity means several refill cycles a day
- Filters rated for 600 gallons, so cost per gallon is higher than the Classic
- Owners report some failures, leaks and weak support
The best-documented countertop RO we found. It has certification that names its models, strong independent test results and a glass carafe. Daily convenience is its weak spot.
