Corrections Policy

Our Commitment to Accuracy

FilterTested is committed to publishing accurate, research-backed information about water filtration systems and related technologies. We rely on manufacturer specifications, NSF/ANSI certifications, independent lab reports, and peer-reviewed research to inform our editorial analysis. Despite our rigorous process, errors can occur, and we are dedicated to correcting them promptly and transparently.

Types of Corrections

We categorize corrections based on the nature of the error:

Factual Errors

Incorrect statements about water contaminants, health standards, or regulatory requirements. These are corrected immediately once verified and noted with a correction statement.

Product Specification Errors

Incorrect flow rates, filter capacities, dimensions, or compatibility claims. We verify these against the manufacturer's official documentation and NSF/ANSI certification listings before publishing corrections.

Methodology Errors

Errors in how we describe our research process, rating criteria, or comparison methodology. These corrections may affect how readers interpret our recommendations and always receive prominent correction notices.

Source or Citation Errors

Broken links, misattributed quotes, or incorrect references. These are corrected and, where possible, the original source is restored or replaced with an equivalent authoritative source.

Visible Correction Notes

All material corrections are published as a visible correction note at the top of the affected page. Each correction note includes:

• The date the correction was published
• A description of the error and what was changed
• Thanks to the reporter (if they choose to be identified)
