What separates the best air purifiers for smoke on this page?
Three units, three different answers. The Levoit Core 600S scores 8.4 and costs $299.99. It cleared our test room to 90% in 9 minutes, is rated for 635 sq ft, and runs an app with scheduling, an air-quality graph and auto mode. The trade-offs: 58 dB on high, and filters every 6–8 months at $55.
The Winix 5500-2 scores 8.3 at $249.99. Its granular carbon filter removed cooking smell in our test where thin filters did not, and it cleared to 90% in 15 minutes. It is rated for 360 sq ft and regularly sells well below $200. Two catches: the PlasmaWave ioniser, which you should turn off, and a low setting louder than the Coway.
The Coway Airmega 400 scores 7.6 at $449.99. It cleared our room in 8 minutes, the fastest here, and its low setting is 22 dB. Rated coverage is 1,560 sq ft, and its dual filters last a year. It is heavy and boxy, and the filters run $130 a year.
