Levoit is producing some of the best air purifiers out there. This time, I will do an in-depth comparison of the Levoit EverestAir and the Core 400S air purifiers.
These two air purifiers characterize totally different design principles; the Core 400S is cylindrical, the EverestAir is rectangular, both are very powerful, and are equipped with plenty of smart features.
The Levoit EverestAir has a CADR of 360 CFM (612 mÂł/h), while the Levoit Core 400S has a CADR of 260 CFM (442 mÂł/h).
We tested their performance, noise levels, and power. Keep reading and find out the real differences between these two air purifiers.
Our Verdict
Frankly, whichever of these two models you choose, you won’t go wrong. However, based on all the tests, the Levoit EverestAir proved to be a better choice than the Core 400S.
Still, the Core 400S is somewhat more affordable, easier to maintain, and also a very good air purifier.

Performance Test – Comparison
In accordance with their room coverage, I tested the performance of these two air purifiers in rooms of different sizes.
The Levoit EverestAir covers rooms up to 558 sq. ft. (52 m²), while the Levoit Core 400S covers rooms up to 403 sq. ft. (37 m²).
Particle Removal Tests - Comparison
We placed the Levoit EverestAir and Levoit Core 400S in two separate tests and measured their performance using the Temtop laser particle meter.
However, the most important test is the one in a room of 560 sq. ft. (52 m²). In just 60 minutes of operation at maximum speed, the Levoit EverestAir improved air quality by 96%, while the Core 400S improved air quality by approximately 94% in the same test.
In addition, the Levoit EverestAir also showed a somewhat better result in neutralizing bad odors and in smoke removal tests, and is overall slightly more efficient than the Core 400S.
Noise Level Test – Comparison
When it comes to the noise test, the first thing to compare is the number of fan speeds, and what’s interesting here is that both devices have five fan speeds.
We tested the noise levels at each speed individually and compared the results. At the lowest speed, the Levoit EverestAir produces noise of 40.1 dBA, while the Levoit Core 400S is somewhat louder, producing 42.1 dBA.
Noise Levels - Comparison
Comparison of noise levels at all fan speeds between the Levoit EverestAir and Levoit Core 400S air purifiers.
At maximum speed, the situation is somewhat different. The Levoit EverestAir produces noise of 63.2 dBA, while the Levoit Core 400S produces noise of 59.9 dBA.
| Fan Speed | Levoit EverestAir (dBA) | Levoit Core 400S (dBA) |
|---|---|---|
| Sleep Mode | 40.1 dBA | 42.1 dBA |
| Speed 1 (Low) | 41.2 dBA | 43.6 dBA |
| Speed 2 (Medium) | 46.5 dBA | 47.8 dBA |
| Speed 3 (High) | 53.3 dBA | 55.4 dBA |
| Speed 4 (Turbo) | 63.2 dBA | 59.9 dBA |
If we compare the noise levels at each speed individually, we can see that the Levoit EverestAir is somewhat better optimized at almost all speeds except at max speed.
However, given that both devices are generally quiet and the differences aren’t huge, I would say the result of this test is a draw.
Operating Costs – Comparison
When comparing power consumption, the first thing worth mentioning is that the Levoit EverestAir has a 70W motor, while the Levoit Core 400S has a 38W motor.
If you were to use these two devices at max speed, 24 hours a day, for a period of one month, your electricity bill would increase by approximately $5.34 in the case of the Levoit EverestAir, and by approximately $3.06 in the case of the Levoit Core 400S.
Monthly Power Consumption Cost - Comparison
Comparison of monthly power consumption costs for the Levoit EverestAir and Levoit Core 400S air purifiers at all fan speeds.
In addition to this cost, there is also the cost of replacement filters, which are somewhat longer-lasting in the case of the EverestAir, but are also somewhat more expensive.
| Fan Speed | Levoit EverestAir (W + $/month) | Levoit Core 400S (W + $/month) |
|---|---|---|
| Standby | 1.6W ($0.14) | 0.9W ($0.07) |
| Sleep Mode | 4.8W ($0.42) | 3.3W ($0.28) |
| Speed 1 (Low) | 9.3W ($0.82) | 5.8W ($0.5) |
| Speed 2 (Medium) | 13.9W ($1.22) | 8.8W ($0.77) |
| Speed 3 (High) | 23W ($2.02) | 16.1W ($1.41) |
| Speed 4 (Turbo) | 60.9W ($5.34) | 35W ($3.06) |
All in all, I think it is more than obvious that the Levoit Core 400S is more affordable to maintain on an annual basis. It uses long-lasting filters, which are much more affordable, and consumes much less energy than the EverestAir.
