Water filters certified to remove Selenium
Essential trace element but toxic in excess; MCL 50 ug/L. Hair/nail loss, nerve damage.
"Certified" means the model is listed in the NSF, WQA, or IAPMO public database as reducing Selenium — 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 Selenium.
