Our Methodology

We test each air purifier in a sealed 250 sq ft room with a particle counter, measuring PM2.5 reduction over 1 hour. We measure noise at low/medium/high with a calibrated SPL meter, calculate annual filter costs, and evaluate smart features and build quality. No manufacturer has editorial influence.
