Affiliate disclosure

If you buy through these links, we may earn a commission at no extra cost to you. It never changes what we mark as certified.

Store buttons appear on product pages, always with this notice beside them. When a store or brand affiliate program approves VerifiedFilter, the links to that store may carry a tracking tag, and a purchase made through them may earn us a commission. As of 16 Oct 2026, no program has approved the site yet, so the store links carry no tracking tags.

What commissions never change

• The label on a claim comes only from a certification listing (or its absence). No brand can pay for a label.
• Which products appear for your water depends only on what their listings certify.
• We don’t show prices, and we don’t accept free products in exchange for coverage.
