Treatment, if a finding establishes a need

What can carry a PFHxS reduction claim

  • Reverse osmosis

    Semi-permeable membrane separation removing dissolved minerals, heavy metals, and persistent fluorinated chemicals down to 0.0001 microns.

  • Activated carbon (GAC)

    Highly porous adsorption media targeting chlorine, disinfection byproducts, volatile organic compounds, and organic chemicals.

  • Anion exchange

    Synthetic polyvalent resin beads that exchange unwanted dissolved ionic contaminants for harmless benchmark ions.

What does not help

Boiling does not remove a dissolved chemical compound and can concentrate it. Many pitcher and refrigerator filters carry no verified claim for a compound like this at all.
