Levoit EverestAir

Levoit Everest Air

The Levoit EverestAir is a medium sized air purifier with a large coverage area. With 2 air changes per hour, it can cover an area of 1,395 sq. ft. Plus, it comes with a plethora of features and options to fully customize the device. The touch buttons and VeSync app allow the user to fit the EverestAir to their needs. Furthermore, it has solid purification performance bringing PM2.5 down to 0.1.


  • Incredibly easy to set up, use, and maintain
  • Excellent performance; brought PM2.5 to 0.1 and PM10 to 0.2
  • Large coverage area, 1,395 sq. ft.


  • Wheels do not rotate


Easy to use HEPA air purifier
  • Design - 94%
  • Performance - 98%
  • Quality - 90%
  • Usability - 96%
  • Value - 90%


One of the biggest reasons to buy the Levoit EverestAir is the usability. The various features and settings allow the device to be hands-off or hands-on depending on your needs. Additionally, this great usability is paired with great purification performance. In our tests PM2.5 was brought down to 0.1 while PM10 was reduced to 0.2. All of this comes packaged with a large coverage area.

Purification Performance

For the purification test, we set up the Levoit EverestAir in a medium sized room (~14’ x ~10’) in our office. We took a baseline measurement of the current air quality before starting the test, turned on the EverestAir, and set it to the max fan speed.

After 1 hour, we took an additional measurement of the air quality which we then used to compare to the baseline. This comparison helps us determine the performance of the Levoit EverestAir.

Starting Baseline

  • PM2.5: 1.1
  • PM10: 2.1
  • Particles: 264
  • AQI: 3

After 1 Hour

  • PM2.5: 0.1
  • PM10: 0.2
  • Particles: 10
  • AQI: 1

The Levoit EverestAir was able to reduce PM2.5 to 0.1 and PM10 to 0.2. This performance is excellent, however, it would have been nice to see PM10 at 0.1.In general, we are looking for the 4 key data points we measure to be as close to 0 as possible.

Below, we’ve included information on the testing criteria and what defines good vs. bad air quality.

Air Quality Pm 25 Index

In order to get these measurements, we used the Temtop LKC-1000S+ professional air quality detector. This device allows us to get precise readings and performance bearings before and after the test.

The Filters

A major factor to the EverestAir excellent performance are the filters. These include:

  • Pre-filter
  • HEPA filter
  • Activated carbon filter

First, the pre-filter catches the larger particles floating in the air, like hair or dust.

Next, the HEPA filter does the majority of the cleaning, capturing particles as small as 0.3 microns.

Finally, the activated carbon filter works in tandem with the others, removing VOC’s and odors from the surrounding air.

Noise Test

To test the noise levels of the Levoit EverestAir, we set it up in a medium sized room where we took a baseline measurement of the current noise level with a sound meter.

After measuring the ambient noise levels, we ran the EverestAir on its lowest and highest fan speed for 30 seconds and measured the generated noise from about 3’ away. During the testing time, we measure the minimum and maximum recorded sound levels, as well as the average decibels generated for the duration of that 30 seconds.

Baseline16.6 dB21.8 dB36.4 dB
Low Fan Speed17.5 dB30.8 dB24.9 dB
High Fan Speed39.4 dB53.2 dB46.0 dB

On average, the Levoit EverestAir has a noise range of 24.9 – 46.0 dB. The quietest setting should be sufficiently silent to not disturb anyone during the night, generating 24.9 dB of sound on average. On the highest setting, the average decibel generated is 46.0 dB, which is considerably louder, but nothing too alarming.

Common noise levels:

  • 20 dB – rustling leaves
  • 30 dB – whisper
  • 40 dB – quiet library, babbling brook
  • 50 dB – refrigerator, moderate rainfall
  • 60 dB – normal conversation, dishwashers
  • 70 dB – traffic, showers
  • 80 dB – alarm clock, telephone dial tone

Usability Tests

Overall usability for the Levoit EverestAir is fantastic. It has a lot of similar features that other Levoit air purifiers have, with a few extra.

One of the more interesting features on the EverestAir is the inclusion of adjustable vents. With a touch of a button you can lift or lower the top-seated vents to direct airflow. It can be a nice addition, but ultimately doesn’t affect purification performance. 


Setup for the Levoit EverestAir takes a single person 5 minutes, not including app setup. This is largely due to the few included pieces in the box.

Here is what’s included:

  • Levoit EverestAir air purifier
  • 2-in-1 HEPA/Carbon filter (pre-installed)
  • Power cord
  • Manuals

To set up the device you simply need to plug in the power cord and plug in the device. Please note: make sure to remove the packaging surrounding the pre-installed filter before plugging in the device.

Controls & Display

Once the Levoit EverestAir is running you have a few means to control it.

First, on top of the device is a display and touch buttons. Displayed on top is the current air quality (measured by internal sensors), filter life information, and other basic device info. It gets this information via a three channel laser dust sensor located inside the device. 

The touch buttons give you access to a number of features, including:

  • Sleep mode
  • Auto mode
  • Turbo mode
  • Cycle through air quality information
  • Check filter life
  • Fan speeds
  • Adjust vent angle
  • Set a timer
  • Turn on/off device

These buttons are responsive and easy to interact with, no complaints here. 

Levoit App

For further control you can connect to the VeSync app. The connection process is easy, simply follow the in-app instructions, which shouldn’t take longer than 10-15 minutes. With the app, you can access all the same features on the physical touch buttons, and even more.

These features include:

  • Air quality information
  • Purification reports
  • Auto mode
  • Auto mode settings
  • Custom scheduling
  • Custom timers
  • Voice commands
  • Smart scenes

The app is easy to navigate and use, and is a great addition for those who set up the air purifier to exactly fit their needs.


For maintenance, there is nothing out of the ordinary with the Levoit EverestAir. You will need to replace the filters, which tend to last 6-12 months, depending on usage and environment. Both the HEPA filter and carbon filter come as a singular unit, replacing them will happen at the same time.

In addition, you will need to occasionally clean the pre-filter, which can be wiped clean or washed (remember to dry before re-installing). You’ll also need to infrequently wipe the sensors clean to make sure they work optimally. 

Size & Coverage Area

In terms of size, I would consider the Levoit EverestAir a medium sized air purifier. It stands on wheels, but they don’t rotate 360°, so moving the device around can be a little tricky.

Here are the exact dimensions of the Levoit EverestAir:

  • Width – 8.5”
  • Length – 18.9″
  • Height – 23.2″
  • Weight – 20.3 lbs.

The EverestAir covers up to 558 sq. ft. with 5 air changes per hour (ACH), and an area of 1,395 sq. ft. with 2 ACH. While the Levoit’s CADR comes in at 360 CFM.

Should you buy the Levoit EverestAir?

I would recommend the Levoit EverestAir if you’re looking for the following features:

  • Fantastic usability: From beginning to end the EverestAir was as simple or complicated as I wanted it to be. Setup is incredibly easy, and maintenance is simple. After that the Levoit has all of the options and features so the user can set it up exactly how they want. With the inclusion of the app, the EverestAir can become incredibly hands-off/on all according to your needs. 
  • Great purification performance: While performance wasn’t perfect , its results are nothing to scoff at. Bringing PM2.5 down to 0.1 is phenomenal. While PM10 could be brought down a little lower, 0.2 is still fantastic. 
  • Purification while you sleep: For those worried about a loud device while they sleep, they don’t have to worry about the EverestAir. While it can be loud at its maximum setting, it can become incredibly quiet at its lowest setting. This can be easily accessed via sleep mode, which also dims the display on the device.
