Verdict

Scores 8.75/10, tied for 17th of the 20 RO systems we track. At $499.99 it costs more than the category median of $459.99. Brio publishes its own test data, but we found no certifier listing for its reduction claims; 12 of the 20 RO systems have one. Its cartridge cost of about $340 a year is 1.7 times the $205-a-year median of the 19 RO systems with a stated cartridge cost.
