PRIVACY POLICY
Last updated: October 1, 2026. This policy explains what information FilterTier may collect, how it may be used, and the choices available to visitors.
We may collect information you voluntarily submit through forms, questionnaires or other interactive tools, such as contact information, water-source details, home size, treatment preferences and other information you choose to provide. We may also collect standard technical and usage information such as device type, browser, pages viewed, referral source, approximate location, IP address and interactions with the site.
Information may be used to operate and improve FilterTier, personalize filter recommendations, measure site performance, understand how visitors use the site, respond to inquiries, prevent abuse, maintain security, and improve our research, comparison tools and content.
FilterTier may use cookies, analytics tools, advertising or attribution technologies, embedded content, hosting providers and other third-party services. These services may collect information according to their own privacy policies. Browser settings and privacy controls may allow you to limit or block certain cookies or tracking technologies.
Some links may be affiliate or referral links. FilterTier may receive compensation if you purchase through certain links. Compensation does not change the methodology used to evaluate products, and brands cannot purchase a higher WaterScore or ranking position.
We may share information with vendors and service providers that help operate the site, process forms, provide analytics, host content, prevent fraud or perform related services. We may also disclose information when required by law, to protect rights or safety, or in connection with a business transfer. We do not state that personal information is sold unless that practice is specifically disclosed.
We retain information for as long as reasonably necessary for the purposes described above, subject to legal, operational and security requirements. No internet service can guarantee absolute security, but reasonable measures may be used to protect information.
You may choose not to submit optional information. You may also use browser privacy settings or applicable opt-out controls for cookies and similar technologies. Where applicable law provides additional privacy rights, requests may be submitted through the contact method provided on the site.
FilterTier is intended for a general audience and is not designed to knowingly collect personal information from children.
We may update this Privacy Policy as the site, tools or legal requirements change. The effective date at the top of this page will be updated when material changes are made.
Questions about this policy can be submitted through the contact options made available on FilterTier.
FilterTierEvidence-first whole-home water treatment comparisons built around your water, your house and your priorities.
FilterTier provides independent comparison and educational information, not medical, plumbing, engineering or legal advice. Product claims, certifications, specifications, prices, warranties and availability can change; verify current details with the manufacturer and use water testing and a qualified professional when appropriate. Some outbound links may be affiliate/referral links, which may earn FilterTier compensation without changing the price you pay or the scoring methodology.
