| Spec | Blueair Blue Pure 311i+ Max | Levoit Vital 200S | Weight |
|---|---|---|---|
| Smoke CADRSmoke is the hardest of the three AHAM CADR tests, so we use it when listed. Levoit lists one headline CADR, and we use that. Shark, Honeywell, Molekule and IQAir don't publish an AHAM CADR, so those cells are blank and score at the lowest published value in the category. | 339 CFM | 250 CFM | 40% |
| CADR per wattComputed by us: smoke CADR divided by the maker's rated or maximum power. Higher means more clean air for the electricity, which matters for a machine that runs all day. | 8.9 CFM/W | 5 CFM/W | 15% |
| Quietest settingThe lowest listed noise level, usually sleep mode. Makers measure at different distances, so treat differences of 1–2 dB as a tie. | 23 dB | 23 dB | 10% |
| Loudest settingNoise at top speed, which is what you hear when you run it hard for smoke or cooking. Left blank when the maker lists only the minimum. | 50 dB | 54 dB | 10% |
| Carbon or odor stage includedYes when the filter in the box includes an activated-carbon or deodorization stage, per the maker. HEPA alone traps particles but not odors or gases. | Yes | Yes | 10% |
| Main filter lifeThe maker's 'up to' figure for the main HEPA filter. Makers assume different daily run times (noted on each product), so this is a rough guide to running costs. | 9 months | Not listed | 15% |
