Real-world testing based on CADR, filtration speed, replacement filter costs, and value for money.
To evaluate real-world air cleaning performance, each air purifier was placed in controlled test rooms ranging from 150 to 500 sq ft. The AQI was elevated above 999 using incense smoke, and purifiers were timed to measure how quickly they brought the air down to safe, breathable levels. Replacement filter availability and long-term costs were also factored into final rankings.
