About AirFilterGuru
Independent air purifier analysis built on verified data and technical specifications, not manufacturer claims.
Our Mission
AirFilterGuru exists because most air purifier reviews recycle manufacturer marketing copy without scrutiny. Our analytical team conducts deep-dive research into certified performance data, independent lab reports, verified CADR ratings, and long-term owner feedback — then cross-references everything against published technical specifications. Our goal is simple: help you breathe cleaner air without wasting money on the wrong product.
The People Behind the Reviews
Sarah holds a PhD in Environmental Engineering from MIT and spent 8 years at the EPA studying indoor air quality before founding AirFilterGuru in 2019. She leads our technical analysis framework and oversees all product evaluations.
Marcus is a certified HVAC engineer with 15 years of experience in air filtration systems. He designed our data verification protocol and ensures all CADR figures and performance claims are cross-referenced against certified sources.
Priya is a registered nurse and allergy specialist who brings a clinical perspective to our analysis. She synthesizes long-term owner feedback from allergy and asthma sufferers to assess real-world effectiveness beyond the spec sheet.
Our Research Methodology
Every product we analyze goes through a standardized 8-step evaluation process developed with input from environmental engineers and HVAC specialists.
We source CADR ratings exclusively from AHAM-certified test results and independent third-party lab reports — never from manufacturer self-reported figures.
Our team performs a detailed breakdown of filtration technology, airflow mechanics, filter media grades, and stated coverage claims against verified CADR benchmarks.
We cross-reference manufacturer coverage claims against AHAM's 2x and 5x air change formulas to assess whether stated room sizes are realistic or inflated.
We analyze decibel ratings from independent acoustic tests and verified owner reports across all speed settings, flagging discrepancies from manufacturer specs.
We aggregate structured feedback from verified owners across multiple platforms, weighting responses from allergy and asthma sufferers for clinical relevance.
We evaluate wattage data across all speed settings from verified sources and calculate annual running costs at the US average electricity rate.
We model total cost of ownership over 3 years, factoring in replacement filter pricing, filter lifespan, and energy costs to surface the true long-term value of each unit.
We revisit every ranking annually to incorporate new certified test data, updated owner feedback, and comparisons against new market entrants. Ratings are updated when the data changes.
Editorial Independence
AirFilterGuru is reader-supported. When you buy through our affiliate links, we may earn a commission at no extra cost to you. This is how we fund our testing program. However, our editorial process is completely independent of our affiliate relationships — we have never and will never adjust a rating, ranking, or recommendation based on affiliate commission rates. Products are ranked solely on performance. Our lowest-ranked products often have the highest affiliate payouts; our top picks are chosen on merit alone.
