Real-world AQI testing and long-term filter evaluations to help you breathe cleaner air at home.
Each air purifier was tested in room sizes from 150 to 500+ sq ft. We artificially raised room AQI levels above 999 using incense sticks and timed how quickly each purifier brought the air back down to safe levels. We also evaluated real-time display accuracy, noise levels, filter lifespans, and long-term replacement costs.
