Levoit Vital 100S-P vs Core 400S-P: Core can serve a larger room target, and both already come with the app

Quick verdict

In a smaller room, the shallow body and washable prefilter make the Vital 100S-P easier to place and keep up, so pick it there. Once your room exceeds Vital's published 222-square-foot rating at 4.8 air changes per hour, pick the Core 400S-P. VeSync control comes with both, so needing an app doesn't by itself justify the larger purifier.

Before you buy

Why, and what it costs you

The size decision shifts with a 300 sq ft room

On the maker's stated 4.8 ACH basis, a 300 sq ft room is larger than Vital's 222 sq ft label and smaller than Core's 358 sq ft label. That makes Core the candidate to size further for that room. It is no promise that a quiet fan mode reaches the same coverage.

Where this comes from

300 - 222 = 78 sq ft over Vital's label, and 358 - 300 = 58 sq ft under Core's label. Both published area figures are based on 4.8 ACH.

The catch

Levoit Vital 100S-P

Its 222 sq ft room label limits what it can do in a larger room.

The catch

Levoit Core 400S-P

The combined filter on it cannot be washed.

Which one fits

Pick the situations that sound like you

  • I'm checking a 300 sq ft room against the stated 4.8 ACH labels

    Vital falls short of that area. Core's label covers it, depending on ceiling height, placement and fan setting.

In practice

Differences you will notice

The size decision shifts with a 300 sq ft room

On the maker's stated 4.8 ACH basis, a 300 sq ft room is larger than Vital's 222 sq ft label and smaller than Core's 358 sq ft label. That makes Core the candidate to size further for that room. It is no promise that a quiet fan mode reaches the same coverage.

How we worked this out

300 - 222 = 78 sq ft over Vital's label, and 358 - 300 = 58 sq ft under Core's label. Both published area figures are based on 4.8 ACH.

Smaller footprint does not mean narrower cabinet

Vital's bounding base takes up about 79.4 square inches against 116.6 for Core, yet Vital is 1.8 inches wider. Vital can suit a shallow spot along a wall, and Core can suit a narrow opening. Neither calculation counts the airflow space that is required.

How we worked this out

12.6 × 6.3 = 79.38 in² and 10.8 × 10.8 = 116.64 in². Core is narrower by 12.6 - 10.8 = 1.8 inches.

A washable prefilter doesn't cancel the replacement budget

You can rinse the separate prefilter on the Vital. Core calls for dry cleaning of its outer surface. Each still needs its main filter replaced, so picking Vital for washability does not make the whole filtration system a permanent filter.

How we worked this out

The product page for Vital lists a washable prefilter and a separate main filter. Core's US manual says to brush or vacuum and forbids washing the combined filter.

Plug in your numbers

Can either purifier keep up with your room?

This checks hard limits only. Personal preferences are left out of the math.

Levoit Vital 100S-P

Check this one yourself

We do not have a comparable verified smoke CADR for this exact model.

Levoit Core 400S-P

Works with your numbers

231 CFM of verified clean-air delivery works out to about 5.8 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 100S-P

  • Despite the smaller base area, the cabinet is wider than Core's.

With Levoit Core 400S-P

  • More depth, more height and a heavier lift come with it.

Change of plan

When the answer changes

On the published 4.8 ACH basis, your room is over 222 and no more than 358 sq ft

Go with Levoit Core 400S-P. Core carries the larger label that applies. Confirm the ceiling height and fan setting.

You need a washable prefilter

Go with Levoit Vital 100S-P. Vital provides one.

You need a washable prefilter and the published room-size requirement of 300 sq ft

Neither model fits. In this pair, each model satisfies just one of those requirements.

Decision guide

How to decide

Pick the Vital 100S-P for a smaller room where the shallow body and washable prefilter ease placement and upkeep. Pick the Core 400S-P when your room is larger than Vital's published 222-square-foot rating at 4.8 air changes per hour. Both have VeSync control, so an app requirement alone is no reason to buy the larger purifier.

01

Settle the room measurements before the body shape

Measure the connected space the purifier will really serve and not just the area next to it. The current 4.8 ACH labels set these models meaningfully apart. A doorway into another occupied room, a high ceiling or low-speed operation can call for more airflow than the floor-area label suggests.

02

Mark out space for the intake

Core is narrower, while Vital is lower and shallower. Tape the cabinet outlines on the floor, then add the clearance the manual calls for. Squeezing a unit into a cupboard or behind furniture can cost it the placement advantage that made it attractive.

03

Pick the upkeep routine you'll stick with

In a home with shedding pets, a removable washable prefilter can be convenient as long as it is fully dry before it goes back in. Core's outer surface needs brushing or vacuuming. Budget for the correct replacement filter, and follow the model-specific instructions instead of treating every Levoit filter alike.

Check these before you buy

  • For every coverage figure, check the room area, the ceiling height and the circulation rate behind it.
  • Set aside intake clearance on top of the stated cabinet dimensions.
  • Verify the exact replacement filter and follow its instructions for washing or dry-cleaning.

What this page can’t tell you

  • No cleaning test at matched noise, health-outcome test or electricity test was performed. Generic CADR labels are never quietly treated as smoke CADR.
  • This site's room calculator relies on pollutant-specific CADR where it exists, with a 5 ACH target. The result can differ from the manufacturer's 4.8 ACH room label.
