About David

David Wilson is the Comparison Editor at The Air Purifier Guide. His work focuses on head-to-head product comparisons, long-term ownership cost reports, and energy efficiency analysis. David brings an engineering mindset to product evaluation — he cares less about marketing claims and more about measurable performance data over time.

With a background in mechanical engineering from Georgia Tech, David understands the physics behind air filtration at a technical level. His comparison articles break down exactly how different filter technologies (HEPA, activated carbon, UV-C, ionizers) perform against specific pollutants, using manufacturer data and independent test results.

Background & Expertise

• Education: B.S. in Mechanical Engineering, Georgia Institute of Technology
• Specialization: Product comparison methodology, filter lifecycle cost analysis, energy efficiency calculations
• Technical focus: HEPA filter grades (H13 vs H14), activated carbon adsorption capacity, ACH (Air Changes per Hour) calculations
• Industry standards: References AHAM AC-1, ASHRAE 62.1, and EPA indoor air quality guidelines

Comparison Methodology

"A fair comparison means testing two products against the same criteria, in the same conditions, with the same metrics. If I can't put a number on it, it doesn't go in the comparison table."

David's comparison articles follow a standardized framework: CADR per dollar, noise-to-airflow ratio, 5-year total cost of ownership, filter availability and pricing, and smart feature utility. This methodology allows readers to make objective decisions based on their specific priorities.
