About Clean Air Wiki

The Clean Air Research Team is a editorial group specializing in indoor air quality analysis. We evaluate air purifier specifications against industry standards — including AHAM certification, HEPA filtration grades, and CADR testing protocols — to help consumers make informed decisions.

Our team includes researchers with backgrounds in environmental science, consumer product analysis, and technical writing. We are not affiliated with any air purifier manufacturer, retailer, or trade organization.

Air purifier marketing is often vague, inconsistent, and difficult to compare across brands. Proprietary filter names, inflated coverage claims, and missing CADR data make it hard for consumers to evaluate products objectively.

Clean Air Wiki exists to solve this problem. We standardize how air purifier data is presented — using consistent units, transparent cost calculations, and clear methodology — so you can compare products on equal terms.

We focus on three principles:

• Spec-based evaluation — Every assessment is grounded in published specifications, not subjective impressions
• Transparency — Our methodology, data sources, and assumptions are fully documented
• Editorial independence — No manufacturer can pay for placement, favorable coverage, or inclusion

Product database — We maintain a curated database of air purifiers available in the United States, with standardized specifications including CADR ratings, noise levels, filter types, and running cost estimates.

Comparison tools — Our side-by-side comparison tool lets you evaluate up to three products using consistent metrics and standardized cost calculations ($0.16/kWh, 8 hours/day usage).

Guides — In-depth, structured guides covering specific use cases (allergies, smoke, pets), technologies (HEPA, carbon filtration), and decision factors (room sizing, running costs).

Q&A — A community question-and-answer section where users can ask specific questions about air purifiers and indoor air quality.
