Levoit Vital 200S-P vs Blueair Blue Pure 311i Max
Two medium-room candidates with different shapes. Coverage, placement and replacement filters matter more than a generic winner.
Levoit: shallower cabinet
The Vital's published depth is 8.5 inches. Shortlist it where depth is tight, while allowing the manufacturer's required clearances.
Blueair: larger listed coverage
The 311i Max specification section gives 439 ft² at 4.8 ACH, compared with 388 ft² for the Vital. Recheck the exact model and room.

What the coverage difference means
At the same stated 4.8-ACH basis, the published areas differ by 51 ft². For a 400 ft² room, only the Blueair's listed area clears that simple area check. Higher ceilings or a connected room can change the requirement; this is a shortlist screen, not a performance guarantee.
Blueair's page title mentions 465 ft², but the technical specification section and FAQ list 439 ft². This comparison uses the technical section and flags the discrepancy rather than quietly adopting the larger number.
Do not calculate an airflow percentage advantage from the CADR row: Levoit's cited list does not identify the test pollutant. Use the room-size guide to understand the limits of area and CADR claims.
Shape may matter more than a few inches of height
The Vital is wider and shallower; the Blueair is closer to square. Mark out both footprints in the intended location. Leave room to remove the filter and keep each air intake clear according to the relevant manual.
Both noise ranges start at 23 dB, but that does not establish equal airflow at the quietest setting. The different maxima also do not establish which unit is quieter at matched cleaning performance.
Filter cost: one purchase is not one year
Levoit's published interval produces an illustrative $49.99–$99.98 annual filter budget. Blueair's $44.99 filter works out to about $59.99 annually only if it lasts exactly nine months; more frequent changes cost more. These are arithmetic scenarios, not tested running costs. Neither includes electricity.
The $5 difference in filter price is not enough to name an ownership-cost winner. Check availability and whether the selected offer includes recurring delivery. See the complete filter-cost comparison.
