Levoit manufactures some of the best air purifiers out there. In this case, I will make an in-depth comparison of Levoit EverestAir and Core 400S air purifiers.
These two air purifiers feature completely different design principles; What is Core 400S cylindricalEverestAir i a rectangleboth are very powerful, and equipped with many smart features.
Levoit EverestAir has CADR of 360 CFM (612 m³/h)while the Levoit Core 400S has CADR 260 CFM (442 m³/h).
We tested their performance, noise levels, and power. Read on and find out the real difference between these two air purifiers.
Our Decision
In fact, whichever of these two models you choose, you won’t go wrong. However, based on all tests, the Levoit EverestAir proved to be a better choice than the Core 400S.
Still, the Core 400S somehow affordableeasy to maintain, and an excellent air purifier.

Performance evaluation – Comparison
Along with their room settings, I tested the performance of these two air purifiers in rooms of different sizes.
Levoit EverestAir includes rooms up to 558 sq. ft. (52 m²)while the Levoit Core 400S covers rooms up to 403 sq. ft. (37 m²).
Particle Removal Test – A Comparison
We put the Levoit EverestAir and Levoit Core 400S through two separate tests and measured their performance using a Temptop laser particle meter.
However, the most important test is that in the room of 560 sq. ft. (52 m²). In just 60 minutes of high-speed operation, the Levoit EverestAir improved air quality by 96%while the Core 400S improved air quality by approx 94% in the same test.
In addition, Levoit EverestAir also showed a slightly better deodorizing effect and in the emissions test, and is overall less efficient than the Core 400S.
Sound Level Testing – A Comparison
When it comes to sound testing, the first thing to compare is the number of fan speeds, and the interesting thing here is that both devices have five fan speeds.
We tested the noise levels at each speed and compared the results. At low speed, the Levoit EverestAir produces a sound of 40.1 dBAwhile the Levoit Core 400S is loud, it’s productive 42.1 dBA.
Noise Levels – Comparison
Comparison of noise levels at all fan speeds between Levoit EverestAir and Levoit Core 400S air purifiers.
At high speeds, the situation is different. The Levoit EverestAir produces a sound of 63.2 dBAwhile the Levoit Core 400S produces a sound 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 |
| Speed4 (Turbo) | 63.2 dBA | 59.9 dBA |
If we compare the noise levels at each speed, we can see that Levoit EverestAir has been improved at almost all speeds except high speed.
However, given that both devices are generally quiet and the difference is not significant, I would say the result of this test is a draw.
Operating Costs – Comparison
When comparing power consumption, the first thing to mention is that the Levoit EverestAir has it 70W motorwhile the Levoit Core 400S has 38W motor.
If you were to use these two appliances at high speed, 24 hours a day, for a period of one month, your electricity bill would increase to approx. $5.34 in the case of Levoit EverestAir, and approx $3.06 in the case of the Levoit Core 400S.
Monthly Energy Costs – Comparison
Comparison of monthly energy consumption costs for Levoit EverestAir and Levoit Core 400S air purifiers at all fan speeds.
In addition to these costs, there is also a cost to replace the filterslonger lasting in the case of EverestAir, but also more expensive.
| fan speed | Levoit EverestAir (W + $/month) | Levoit Core 400S (W + $/month) |
|---|---|---|
| stand by | 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) |
| Speed4 (Turbo) | 60.9W ($5.34) | 35W ($3.06) |
Overall, I think it’s more than obvious that the Levoit Core 400S is more affordable to keep every year.. It uses filters that last longer, are more affordable, and use much less energy than EverestAir.
