The catch
Levoit EverestAir-P
Independent testing backs up its strong particle removal, though the current filter isn't presented as formally HEPA-certified.
Side by side
The EverestAir-P is the better buy if you want wheels, a slim shape that suits a wall, adjustable discharge and particle data at multiple sizes. When clean-air delivery matters most, the Core 600S-P moves more air and is the stronger choice.
Before you buy
EverestAir's published CADR is a generic 354-CFM figure, whereas Core 600S carries a certified 391-CFM smoke CADR. Because the pollutant labels differ, no like-for-like percentage advantage can be drawn.
Where this comes from
Ranking by percentage needs the same pollutant and operating basis. The records on hand contain no matching smoke figure for EverestAir.

The catch
Even with strong tested particle performance, RTINGS does not classify the current filter as formally HEPA-certified.

Levoit’s two large-room smart purifiers go head to head on airflow, placement, sensing and mobility.
This one comes down to cadr and placement first, then to the limits of your own setup.
Day to day
Relying on automatic air cleaning in a dark bedroom? Core 600S's light-sensor behavior can hold Auto mode to speeds below high and turbo. Pick it when that quieter automatic routine suits the room, and keep its maximum CADR out of any claim about sleep speeds. EverestAir's controls may still work for your routine, but the reviewed evidence includes no equivalent low-speed delivery measurement, so there is no direct nighttime winner.
What matters now is which setting you can use in the dark. The EverestAir generic CADR and the Core 600S smoke CADR as listed should also keep their different measurement labels.
Beside furniture, EverestAir's 8.5-inch depth can help where Core 600S's 12.3-inch depth is awkward. But EverestAir is wider at 18.9 inches and has an adjustable outlet. Choose it only if the wider opening and the discharge direction stay clear as well. Choose Core 600S if a squarer spot on open floor works better. Neither body measurement is a license to slide the purifier tightly into an enclosed shelf.
Width, depth and airflow direction all get checked together here. A shallow body helps only if the intake, the outlet and filter-removal access are still available where it will sit.
Which one fits
Levoit EverestAir-P lists “Casters and adjustable discharge” for mobility and outlet, while Levoit Core 600S-P lists “No casters and fixed top discharge”. This matters if you will lift it, move it, take it somewhere or put it away after each use.
A prefilter that is easy to get to traps coarse hair ahead of the main filter.
In a room of the right size, its verified particle airflow and filter path are a good match for airborne pollen.
Airflow aimed at dust can cut down particles while they are still in the air. Dust that has already settled stays where it is.
Extra ceiling height raises the room volume, and its verified airflow leaves more headroom to handle that.
Levoit EverestAir-P lists “354 CFM, generic manufacturer CADR” for cadr, while Levoit Core 600S-P lists “391 CFM smoke CADR”. Extra published output only helps when your room, surface or workload needs the headroom. On its own, it does not prove better results.

Plug in your numbers
This checks hard limits only. Personal preferences are left out of the math.
We do not have a comparable verified smoke CADR for this exact model.
391 CFM of verified clean-air delivery works out to about 9.8 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.

Levoit, LAP-EL551S-AUS
This premium rectangular Levoit delivers strong large-room airflow and adds wheels, an adjustable outlet and unusually detailed particle sensing.

Levoit, LAP-C601S-WUS
This cylindrical smart purifier moves enough air for a large room while taking up little floor space, and its VeSync controls are polished.

Spec by spec
| Spec | Levoit EverestAir-P | Levoit Core 600S-P | In practice |
|---|---|---|---|
| CADR | 354 CFM, generic manufacturer CADR | 391 CFM smoke CADR | Higher published output is useful only if your room, surface or workload calls for the extra headroom. It does not, by itself, prove better results. |
| Placement | Slim body, casters, adjustable outlet | Compact cylinder, fixed top outlet | Fit can be a hard limit, so measure your space and mounting points before anything else. |
| Sensor display | PM1, PM2.5 and PM10 | PM2.5-focused status | Setup and everyday use depend on it more than the core physical job does. |
| Mobility and outlet | Casters and adjustable discharge | No casters and fixed top discharge | It counts if you plan to lift it, move it, travel with it or store it after every use. |
