Values are from the published EPA record; a contaminant that was never tested is shown as pending, never as a pass. Above the action level is a regulatory trigger for the system, not a measurement of any single home.
What can carry a lead reduction claim
- Reverse osmosis
Semi-permeable membrane separation removing dissolved minerals, heavy metals, and persistent fluorinated chemicals down to 0.0001 microns.
- NSF/ANSI 53NSF/ANSI 53 lead-certified filters
- Replacing lead service lines
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.
A finding establishes the need, the need names the capability, the capability requires a verified certification. No product appears before that sequence completes. Filter Finder →
