Side by side
Blueair Blue Pure 311i Max vs Levoit Vital 200S-P: Blueair weighs less to move, Vital takes less depth along a wall
Quick verdict
The Blueair 311i Max wins on the larger published room rating and on being a lighter unit you may move regularly. The Vital 200S-P is the choice when a shallow rectangular cabinet fits better along a wall. App control and washable prefilters come with both, so let the room and placement decide before convenience features do.
Before you buy
Why, and what it costs you
The advantage in area comes to about 13%
At the same stated air-change rate, Blueair gains 51 sq ft.
Where this comes from
439 − 388 = 51 sq ft. 51 ÷ 388 = 13.1%. It compares capacity and does not reflect a measured difference at quiet settings.

In practice
Differences you will notice
The advantage in area comes to about 13%
At the same stated air-change rate, Blueair gains 51 sq ft.
How we worked this out
439 − 388 = 51 sq ft. 51 ÷ 388 = 13.1%. It compares capacity and does not reflect a measured difference at quiet settings.
Levoit is shallower but wider
Vital is shallower by four inches and wider by 3.1 inches.
How we worked this out
Depth: 12.5 − 8.5 = 4 inches. Width: 15.6 − 12.5 = 3.1 inches. Both are before ventilation clearance.
Blueair lightens the load to lift
Published dry weight is 5.4 lb less.
How we worked this out
13.2 − 7.8 = 5.4 lb, which is roughly 41% below Vital's weight. Handle comfort and one-handed safety are not established by it.
Plug in your numbers

This checks hard limits only. Personal preferences are left out of the math.
Blueair Blue Pure 311i Max
Works with your numbers283 CFM of verified clean-air delivery works out to about 7.1 air changes per hour in this room. Hitting the 5 ACH target takes 200 CFM.
Levoit Vital 200S-P
Check this one yourselfWe do not have a comparable verified smoke CADR for this exact model.
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.

Spec by spec
Where they really differ
| Spec | Blueair Blue Pure 311i Max | Levoit Vital 200S-P | In practice |
|---|---|---|---|
| Room rating at 4.8 ACH | 439 sq ft in technical specifications | 388 sq ft | Because the current Blueair title is different, this comparison relies on its technical table. |
| Cabinet width and depth | 12.5 × 12.5 in | 15.6 × 8.5 in | Space is used differently by a narrow round shape and a shallow rectangular shape. |
| Height | 19 in | 19.8 in | Compared with the floor-plan difference, the difference in height is small. |
| Published weight | 7.8 lb | 13.2 lb | Weigh the lifting and second-outlet access. |
| Rated power | 32 W | 50 W | These are rated inputs. They do not show consumption at equal airflow. |
| Prefilter | Washable exterior fabric prefilter | Washable internal prefilter | Go with the maintenance access and look you like better. |
Trade-offs
What each pick costs you
With Blueair Blue Pure 311i Max
- The exterior prefilter can be seen and needs regular upkeep
With Levoit Vital 200S-P
- There is 5.4 lb more to move
Change of plan
When the answer changes
At the stated rating assumptions, the room sits between 388 and 439 sq ft
Go with Blueair Blue Pure 311i Max. The published capacity that applies belongs to Blueair.
Keep cabinet depth under 10 inches
Go with Levoit Vital 200S-P. That physical limit is cleared by Vital's shallower body.
Decision guide
How to decide
Pick the Blueair 311i Max for the larger published room rating and a lighter unit that may move regularly. Pick the Vital 200S-P when a shallow rectangular cabinet fits better along a wall. Both come with app control and washable prefilters, so settle the room and placement before looking at convenience features.
Begin with your room and skip the headline
At 4.8 ACH, Blueair's current technical table gives 439 sq ft and Vital gives 388. The one-hour coverage headlines don't mean the same level of repeated circulation for either, and a quiet mode won't necessarily deliver the rated maximum.
Sketch the footprint on your floor
Blueair has a more circular 12.5-inch footprint, and Vital is broad and shallow. A narrow alcove can favor Blueair, whereas a wall beside a walkway may favor Vital. Intake and exhaust must stay unobstructed on both.
Consider the chores you'll really do
Access to the washable prefilters works differently on each. Blueair's fabric cover also forms part of its look, while Vital's prefilter sits behind its panel. Both have app control, so that doesn't settle this pair by itself.
What this page can’t tell you
- Blueair's page title currently shows a different area than its technical table does. No comparison of airflow at matched noise, health effects or odor removal is claimed.
