About PureAirPick

PureAirPick exists because most air purifier recommendation sites bury the metric that matters most — CADR — in favour of vague language like "covers up to 500 sq ft" or "99.97% efficiency." Those claims are nearly impossible to compare across brands without standardised testing.

Our Methodology

Every purifier we cover must have an AHAM-verified CADR score (Clean Air Delivery Rate), or we note clearly when it doesn't. CADR is tested independently by AHAM and measures how many cubic feet of clean air a purifier delivers per minute across three pollutant types: smoke, dust, and pollen.

We supplement CADR data with manufacturer specifications, independent lab tests (where available), and community feedback. We do not use proprietary brand metrics (like "CleanSense IQ" or similar) as primary comparison data points.

Data Sources

Our primary data sources are: the AHAM Verifide directory (2,000+ tested models), manufacturer specification sheets, RTINGS.com where available, and Amazon product listings for pricing and dimensions.
