Main trade-off
Levoit Vital 100S-P
The 222 sq ft room label limits its larger-room role.
Head-to-head
Levoit Vital 100S-P vs Core 400S-P: Core handles a larger room target, both already have the app
The short answer
Choose Vital 100S-P for a smaller room where its shallow body and washable prefilter make placement and upkeep easier. Choose Core 400S-P when your room exceeds Vital's published 222-square-foot rating at 4.8 air changes per hour. Both have VeSync control, so an app requirement alone does not justify the larger purifier.
Before you choose
The reasoning and the trade-offs
A 300 sq ft room changes the size decision
At the maker's stated 4.8 ACH basis, a 300 sq ft room is above Vital's 222 sq ft label and below Core's 358 sq ft label. Core is the candidate to size further for that room. This is not a promise that a quiet fan mode reaches the same coverage.
What this is based on
300 - 222 = 78 sq ft above Vital's label. 358 - 300 = 58 sq ft below Core's label. Both published area figures use 4.8 ACH.
Main trade-off

Winner by situation
Start with what you need it to do
I am sizing a 300 sq ft room against the stated 4.8 ACH labels
Vital is below that area. Core's label covers it, subject to ceiling height, placement and fan setting.

What matters in practice
The differences that matter
A 300 sq ft room changes the size decision
At the maker's stated 4.8 ACH basis, a 300 sq ft room is above Vital's 222 sq ft label and below Core's 358 sq ft label. Core is the candidate to size further for that room. This is not a promise that a quiet fan mode reaches the same coverage.
How we reached this conclusion
300 - 222 = 78 sq ft above Vital's label. 358 - 300 = 58 sq ft below Core's label. Both published area figures use 4.8 ACH.
The smaller footprint is not the narrower cabinet
Vital's bounding base occupies about 79.4 square inches, versus 116.6 for Core, but Vital is 1.8 inches wider. A shallow wall-side position can favor Vital while a narrow opening can favor Core. Neither calculation includes required airflow space.
How we reached this conclusion
12.6 × 6.3 = 79.38 in². 10.8 × 10.8 = 116.64 in². Core is 12.6 - 10.8 = 1.8 inches narrower.
A washable prefilter does not remove the replacement budget
Vital lets you rinse its separate prefilter. Core calls for dry cleaning of the outer surface. Both still need their main filter replaced, so choosing Vital for washability does not turn the complete filtration system into a permanent filter.
How we reached this conclusion
Vital's product page lists a washable prefilter and a separate main filter. Core's US manual instructs brushing or vacuuming and prohibits washing the combined filter.

Levoit Vital 100S-P
Needs a manual checkNo comparable verified smoke CADR is stored for this exact model.
Levoit Core 400S-P
Fits these inputs231 CFM of verified clean-air delivery gives about 5.8 air changes per hour here. The 5 ACH target needs 200 CFM.
This uses maximum-speed, pollutant-specific CADR and a five-air-changes-per-hour target. Quieter settings deliver less clean air. It does not substitute raw airflow or a one-change coverage claim.

Meaningful differences
What changes the fit
| What changes | Levoit Vital 100S-P | Levoit Core 400S-P | Why it matters |
|---|---|---|---|
| Published room rating at 4.8 ACH | 222 sq ft | 358 sq ft | Compare the same circulation rate and account for ceiling height. |
| Published CADR | 143 CFM | 231 CFM | These are the current generic CADR labels, not a pollutant-specific head-to-head test. |
| Cabinet width and depth | 12.6 × 6.3 in | 10.8 × 10.8 in | Vital is shallower, while Core is narrower. Intake clearance is extra. |
| Height and weight | 16 in and 8.6 lb | 20.5 in and 11 lb | Check handling and vertical clearance separately from floor area. |
| Prefilter maintenance | Separate washable prefilter | Brush or vacuum the outer filter surface | Core's combined filter must not be washed. |
| Air-quality interface | Indicator rings and VeSync app | Numeric PM2.5 display and VeSync app | Both offer remote settings. The onboard readout differs. |
What you give up
Every choice has a cost
If you choose Levoit Vital 100S-P
- The cabinet is wider than Core despite its smaller base area.
If you choose Levoit Core 400S-P
- It needs more depth, more height and a heavier lift.
Recommendation switch
The decision flips if...
Your room is above 222 and at most 358 sq ft on the published 4.8 ACH basis
Choose Levoit Core 400S-P. Core offers the relevant larger label. Verify ceiling height and fan setting.
A washable prefilter is mandatory
Choose Levoit Vital 100S-P. Vital supplies one.
You need both a washable prefilter and the 300 sq ft published room-size requirement
Choose neither. Each meets only one of those requirements in this pair.
What matters in practice
How to make the call
Measure the room before choosing a body shape
Use the connected space the purifier will actually serve, not just the area beside it. The current 4.8 ACH labels separate these models meaningfully. A doorway to another occupied room, high ceiling or low-speed operation may require more airflow than the floor-area label suggests.
Lay out the intake space
Vital is lower and shallower, but Core is narrower. Tape the cabinet outlines on the floor and then add the manual's clearance. A unit pressed into a cupboard or behind furniture can lose the placement advantage that made it attractive.
Choose the maintenance routine you will follow
A removable washable prefilter can be convenient in a shedding-pet home, provided it is fully dry before refitting. Core's outer surface needs brushing or vacuuming. Keep the correct replacement filter in the budget and use the model-specific instructions rather than treating every Levoit filter alike.
What this comparison cannot tell you
- No matched-noise cleaning, health-outcome or electricity test was performed. Generic CADR labels are not silently treated as smoke CADR.
- The site's room calculator uses pollutant-specific CADR where available and a 5 ACH target. Its result can differ from the manufacturer's 4.8 ACH room label.
