The catch
Levoit Vital 200S-P
The reviewed figure is generic, so no smoke-specific CADR was established
Side by side
Levoit Vital 200S-P vs Blueair Blue Pure 211i Max: Blueair adds rated smoke airflow, but quiet-mode output is unverified
Quick verdict
When a larger room needs the published 435 smoke CFM, choose the Blue Pure 211i Max. For a smaller suitable room where the shallower body and washable mesh suit the space, choose the Vital 200S-P. Vital's generic 250 CFM and the 23 dB minimum on both don't establish matched quiet-mode smoke performance.
Before you buy
Why, and what it costs you
A 500-square-foot room calls for a like-for-like airflow basis
Take a 500-square-foot room with an 8-foot ceiling and a five-air-change target. It needs about 333 smoke CFM. Blueair's published 435 smoke CFM covers that on a nominal, maximum-speed basis. Vital's current page gives a generic 250 CFM and a 388-square-foot room label, which means that source can't offer a matching pollutant-specific smoke check on its own. If this larger-room math is what's driving the purchase, go with Blueair. Vital is still the smaller-space option when its room label and shallower body fit the job.
Where this comes from
Multiply 500 by 8 by 5 and divide by 60 to get 333.3 CFM. Don't divide 435 smoke CFM by 250 generic CFM to build a performance ratio.

How we worked this out
Multiply 500 by 8 by 5 and divide by 60 to get 333.3 CFM. Don't divide 435 smoke CFM by 250 generic CFM to build a performance ratio.
Neither quiet headline says what nighttime capacity is
Each maker publishes a 23 dB figure at the low end, yet neither is linked to a verified overnight CADR in these sources. So you can't say either one cleans the same room more quietly. In a smaller bedroom with pet fur near the intake, Vital's washable mesh and 8.5-inch depth could be handy. Blueair wraps washable fabric around a wider 14.4-inch-square body. Pick the upkeep style and footprint that suit you, then check that the fan speed is tolerable. Neither will clear settled fur off a sofa.
How we worked this out
The source comparison sets the equal minimum sound headlines side by side only to expose the operating condition that is missing. Filtering particles out of the air and removing hair already lying on furniture are separate jobs.
A compact body has value without implying better filtration
Vital's nominal 15.6-by-8.5-inch footprint comes to 132.6 square inches. Blueair's 14.4-inch square is 207.4. That is about 36 percent less body footprint for Vital, before clearances. Go with Vital when the smaller room and the wall space match what it is designed for. Go with Blueair when you need the verified higher-capacity smoke sizing. Footprint and prefilter shape say nothing about which filters more quietly or more effectively.
How we worked this out
15.6 times 8.5 is 132.6, and 14.4 squared is 207.36. That works out to a body-footprint reduction of about 36.1 percent, leaving out ventilation clearance.

Blueair Blue Pure 211i Max
Works with your numbers435 CFM of verified clean-air delivery works out to about 10.9 air changes per hour in this room. Hitting the 5 ACH target takes 200 CFM.
This uses each model’s pollutant-specific CADR at top speed and a target of five air changes per hour. Quieter settings clean less air. Raw airflow and one-change coverage claims are never swapped in.

Trade-offs
What each pick costs you
With Levoit Vital 200S-P
- The current room label reads 388 square feet at 4.8 air changes
With Blueair Blue Pure 211i Max
- The 23 dB minimum is a different condition from maximum output
Change of plan
When the answer changes
An 8.5-inch-deep body fits a smaller suitable room
Go with Levoit Vital 200S-P. Clean the mesh prefilter by washing it as directed. The reviewed figure is generic, so no smoke-specific CADR was established.
A larger room calls for pollutant-specific smoke CADR
Go with Blueair Blue Pure 211i Max. Look after the washable fabric prefilter on the outside. The 14.4-inch-square body takes up more floor space.
Decision guide
How to decide
Pick the Blue Pure 211i Max when a larger room needs its published 435 smoke CFM, and the Vital 200S-P for a smaller suitable room where the shallower body and washable mesh suit the space. Vital's generic 250 CFM and the 23 dB minimum on both don't establish matched quiet-mode smoke performance.
A 500-square-foot room calls for a like-for-like airflow basis
With an 8-foot ceiling and a five-air-change target, a 500-square-foot room requires about 333 smoke CFM. Blueair's published 435 smoke CFM supports that nominal maximum-speed calculation. Vital's current page lists generic 250 CFM and a 388-square-foot room label, so that source alone gives no equivalent pollutant-specific smoke check. When this larger-room calculation drives the purchase, choose Blueair. Vital stays the smaller-space option if its room label and shallower body suit the job. 500 multiplied by 8 multiplied by 5, divided by 60, gives 333.3 CFM. Dividing 435 smoke CFM by 250 generic CFM would manufacture a performance ratio, so don't do it.
Neither quiet headline says what nighttime capacity is
Each maker publishes a 23 dB lower sound figure, but in these sources neither is tied to a verified overnight CADR. So neither can be called the quieter way to clean the same room. In a smaller bedroom with pet fur near the intake, Vital's washable mesh and 8.5-inch-deep shape may be convenient, while Blueair's washable fabric wraps a wider 14.4-inch-square body. Pick the maintenance format and space that work for you, then confirm a fan speed you can tolerate. Neither removes settled fur from a sofa. The source comparison uses equal minimum sound headlines only to show the missing operating condition. Filtering airborne particles and removing hair already on furniture are different jobs.
A compact body has value without implying better filtration
Vital's nominal 15.6-by-8.5-inch footprint comes to 132.6 square inches, against 207.4 for Blueair's 14.4-inch square. Before clearances, that saves about 36 percent of body footprint. Go with Vital when the smaller room and wall space fit its intended role, and with Blueair when the verified higher-capacity smoke sizing is necessary. Neither the footprint nor the shape of the prefilter proves quieter or more effective filtration. 15.6 multiplied by 8.5 equals 132.6, and 14.4 squared equals 207.36. The body-footprint reduction is about 36.1 percent, with ventilation clearance excluded.
What this page can’t tell you
- Label the generic 250 CFM separately, because it can't stand in for a smoke-CADR field in a calculator.
