|---|---|---|---|
| Smoke CADRAHAM's smoke CADR measures how fast smoke particles are removed. IQAir, Shark, Honeywell and Winix's 9800 don't publish one; those score at the lowest published value in the category. | 435 CFM | 352 CFM | 40% |

| Smoke or VOC filter offeredYes when the maker sells a smoke-, toxin- or VOC-specific filter for this model (e.g. Coway Intense Smoke+, Levoit Smoke Remover, Blueair SmokeBlock, Winix SmokeGuard, Rabbit Air Toxin Absorber), or when gas filtration is the main filter (IQAir). | Yes | Yes | 15% |
