Certified filtration

Filters certified for these contaminants

Each filter below holds independent NSF/ANSI health certification for every contaminant this system reported above its health goal. Products are surfaced by certification match, not commercial arrangement.

Recommended hardware links are affiliate placements. Products are surfaced solely because they hold independently verified NSF/ANSI health certifications for the detected contaminants; commercial rankings never override objective scientific data.

A note on your home’s plumbing

Utility data is aggregated at the water-system level and cannot account for plumbing-specific contamination such as legacy household lead service lines. A point-of-use lab test is the only way to verify contamination introduced by your home's plumbing.
