"Certified" means the model is listed in the NSF, WQA, or IAPMO public database as reducing Chromium-6 — not just "tested to" a standard.
Two ways to fix it
Pick the path that fits you
You can start cheap with a no-install filter, or solve it permanently with an installed system that costs far less per gallon over time. Both options below are certified to reduce Chromium-6.
