Editorial Policy

Last updated: January 2026

Our Standards

Clean Air Spaces is committed to providing accurate, practical, and unbiased information about indoor air quality. This document explains how we create and maintain our content.

Research and Sources

How We Research

Our content is based on:

• Peer-reviewed scientific research
• Government and regulatory agency publications (EPA, ASHRAE, etc.)
• Industry standards and specifications (AHAM, HEPA standards)
• Technical documentation from manufacturers
• Established principles of physics and engineering

What We Avoid

• Manufacturer marketing claims without verification
• Anecdotal evidence as primary support
• Outdated research that's been superseded
• Studies with significant conflicts of interest

Accuracy and Corrections

Fact-Checking

We verify claims before publishing and cite sources where appropriate. However, we're not perfect. If you find an error, please contact us.

Updates

We periodically review and update content. Articles include "last updated" dates. Significant changes are noted.

Corrections

When we make factual corrections:

• We fix the error promptly
• Significant corrections are noted in the article
• We don't silently change substantive content

Independence

Editorial Independence

Our editorial content is independent from advertising and affiliate relationships. Advertisers and affiliate partners have no influence over:

• What topics we cover
• What we recommend
• How we evaluate products or technologies
• Our editorial conclusions

No Pay-for-Play

We don't accept payment for positive coverage. We don't guarantee recommendations in exchange for advertising.

Limitations

What We're Not

We're informational, not professional services. We don't replace:

• Medical advice from healthcare providers
• Professional air quality testing
• Engineering assessments of HVAC systems
• Legal advice on tenant rights

Uncertainty

Air quality is complex. Where evidence is mixed, uncertain, or evolving, we say so. We don't pretend to have answers we don't have.

Affiliate Content

Some of our content includes affiliate links. This relationship is disclosed in our affiliate disclosure. The presence of affiliate links doesn't change our editorial standards—we recommend what we believe works, regardless of whether we earn from the recommendation.
