Corrections and Updates

What this corrections log is for

This page is the official, public record of factual corrections and substantive editorial updates to AirPurifierFAQ content. It exists so readers and sources can see what we changed, why, who authorized the change, and where to find the prior version when available.

We log corrections that affect the accuracy, recommendation, or interpretation of content: corrected measurements or specifications, clarified or withdrawn recommendations, factual errors about manufacturers, and any change to safety- or health-related text. Routine copyedits that do not change meaning (minor grammar fixes, cosmetic formatting, or CMS-only style updates) are not listed here unless they affect the article’s accuracy or readers’ decisions.

Definitions: minor versus substantive corrections

• Minor correction — cosmetic edits, punctuation, grammar, or non-meaningful reformatting. These are generally not recorded in this log unless they interact with a substantive point.
• Substantive correction — any change that alters a factual claim, product specification, measurement, price-dependent recommendation, quoted source, or a safety/health-related statement. Substantive corrections are always logged with a short explanation and approver.
• Retraction or reversal — when we remove or reverse a prior recommendation or conclusion, we publish a flagged log entry that explains the basis for the reversal and links to both the original and corrected content where feasible.

Public corrections log

The table below lists recorded corrections, most recent first. Each entry includes the date, the article title (linked), the URL, a one- or two-sentence summary of the correction, the type (minor/substantive/retraction), who approved the change, and a link to the prior archived version when available. Each log row has a stable permalink that can be cited.

How corrections are made (editorial workflow)

1. Discovery — errors may be reported by readers, authors, manufacturers, staff, or detected by internal monitoring.
2. Verification — an editor reviews the evidence. For technical or safety-related items we consult an external subject-matter expert as needed; for medical or clinical claims we follow the expedited review process described in our Medical Disclaimer.
3. Approval — the responsible article editor documents findings and proposes a remedy. Substantive corrections require sign-off from a senior editor; retractions or major reversals require the editor-in-chief’s approval.
4. Publication — the corrected article is updated and, where appropriate, an inline editor’s note is added to the article explaining the change and date. A public entry is added to this log with a permalink to the archived prior version when possible.
5. Archiving — previous versions are retained according to our retention policy and linked from the log entry when legally and technically possible.

How to request a correction

Please submit correction requests using the form on our Contact Us page. To help us act quickly, include the following:

• Article URL and the exact quoted text that you believe is incorrect.
• A concise explanation of the error and how it should read.
• One or more reliable supporting sources (links to primary documents, manuals, or reputable third-party sources). For medical or safety claims include the relevant source and any professional credentials you represent.
• Your name and contact email so we can acknowledge receipt and follow up.

We acknowledge receipt of correction requests within three business days and provide status updates until the issue is resolved.

Transparency, retention and privacy

Log entries remain public and permanent on this page. We do not remove a correction entry; if an entry is superseded by a later update we publish a linked superseding entry that explains the change. We retain archived page versions for at least five years and provide links to archives when legally and technically possible; in some cases legal or technical constraints may prevent us from publishing an archived snapshot.

Personal data submitted as part of a correction request is handled under our Privacy Policy and will not be published without consent. For legal notices or formal claims, see the address and procedures in our Terms of Use.

Escalation and unresolved disputes

• If you disagree with a correction outcome, request a second review and provide any additional evidence; the request will be reviewed by a different senior editor.
• If a dispute remains unresolved, it may be escalated to the editor-in-chief. We will append a public note to the log entry describing the dispute and its status.
• Formal legal or regulatory claims should be delivered as described in Terms of Use; such notices are handled under our legal procedures and may be summarized in the log when appropriate.
