AirVerdicts Puts Indoor-Air Purchases Through the Math
A research site with calculators and comparisons for air purifiers, dehumidifiers, humidifiers, and HVAC filters.
Field notes
AirVerdicts treats indoor-air equipment as a measurement problem rather than a generic product-ranking exercise. Its sizing workflow converts room volume and a target air-change rate into required clean-air CFM, while its ownership tool adds electricity and replacement-filter costs. The site also includes a wildfire smoke planner comparing an EPA-style CADR target with published DIY air-cleaner results. The homepage reports 36 research pages and five live calculators, with comparisons anchored to manufacturer specifications.
