Water filters certified to remove Chromium-6
'Erin Brockovich' chemical. Carcinogenic when ingested. No federal MCL specific to Cr6 (regulated under total chromium); CA has a 10 ppb limit.
"Certified" means the model is listed in the NSF, WQA, or IAPMO public database as reducing Chromium-6 — not just "tested to" a standard.
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.
