Affiliate disclosure

How this site makes money

Water Filter Score is reader-supported. Some product links on this site are affiliate links: we use the Amazon Associates programme, and if you buy through one of them we may earn a commission — at no extra cost to you. As an Amazon Associate we earn from qualifying purchases.

Affiliate status never changes a result

Every ranking, verdict and number on this site is produced from published data before any buy link is attached. A product being available on Amazon, or carrying a higher commission rate, never moves a row, a score or a recommendation. If it did, the site would be worthless to the person reading it.

What we are not

Water Filter Score is an independent comparison tool. We are not affiliated with, endorsed by, or connected to any manufacturer, brand, or certifying body named on this site. We restate published figures with attribution and claim no endorsement by their sources.

This disclosure is made in accordance with the U.S. Federal Trade Commission’s Guides Concerning the Use of Endorsements and Testimonials in Advertising, and with the Amazon Associates Operating Agreement.
