"Certified" means the model is listed in the NSF, WQA, or IAPMO public database as reducing Copper — 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 Copper.
