I then run the purifier on its highest acceptable noise setting (below 65 dB for occupied space use) and measure PM2.5 concentration every 10 minutes

Heres exactly how I evaluate air purifiers: Test Environment Primary Test Space: 728 cubic foot room (approximately 12 13 8 ceiling) Secondary Test Space: Sealed 4 cubic foot acrylic smoke box for controlled tests Ambient Conditions: 68-72F, 40-50% humidity, baseline ambient noise 28-30 dB Equipment Used TSI AeroTrak 9306 Particle Counter ($4,500 professional-grade unit, not a consumer sensor) Measures PM1, PM2.5, PM10 with laboratory accuracy Extech 407768 Sound Level Meter (Type 2, calibrated) Measures decibel levels to within 0.1 dB Kill-A-Watt P3 Power Meter Tracks energy consumption to 0.01W precision Smoke Source: Standardized incense sticks (for repeatability across tests) and actual cigarette smoke (for real-world validation) The 5 Core Tests I Perform Test 1: Smoke Box Speed Test I fill a sealed 4 cubic foot acrylic box with dense smoke until visibility is near zero (PM2.5 typically exceeds 1,000 g/m)
