Levoit is one of the leading names in the air purifier space due to the popularity of its Core Series of air purifiers (the 200S, 300S, 400S and 600S). We have tested all of these air purifiers in our test lab, and they scored very nicely – especially considering they are often much cheaper than competitors.
I first got an email from a reader asking about the Levoit EverestAir in October last year. We had many units scheduled for testing and review at the time, but the idea of a premium model from Levoit interested me, so I added the EverestAir to our list of upcoming reviews.
While the Levoit Core series is all about performance, the EverestAir has the same level of performance in a much more unique and better-looking design.
The EverestAir is currently the only model in this new category from Levoit. It comes with a high CADR of 360 CFM, meaning it can clean the air 4.5 times in a room sized up to 600 sq. ft.
CADR isn’t the only way to evaluate an air purifier, though — our testing showed that the EverestAir performed better than units with a bigger CADR (more on that below).
We recently posted the Levoit EverestAir review on YouTube, so if you prefer to watch rather than read, check it out:
All this to say, here at HouseFresh, we do not rely solely on manufacturers’ claims or suggest any air purifiers until we thoroughly evaluate them.
Using our own testing data allows us to compare units like for like, so we can tell you whether you should go for it or just consider a better/cheaper alternative instead.
The lowdown on the Levoit EverestAir
As always, let me start by sharing the main pros and cons I have identified for the Levoit EverestAir including findings from all my experiments and details from my experience using this unit at home for six months:
What we really like
What we think could be better
On paper, the EverestAir is a high-performing device, so we expected it to perform well in our home lab tests. It is one of Levoit’s most expensive units at $499.99, but we predicted it would fall short of the Levoit Core 600S in terms of performance.

If Apple designed air purifiers
The Levoit EverestAir broke the mold Levoit has gotten us used to, taking some inspiration from modern consumer electronics.
The design of most Levoit air purifiers is pretty standard and generally heavily inspired by existing lines. Looking at the Core series, you’ll quickly grow bored of the same white, boxy look with rounded edges.
But that’s not what the EverestAir is all about…
When looking at the unit from the front, I immediately got Blast Mini vibes:
But all that changes the moment you turn the unit around and find a sleek silver back panel:
The design lines are reminiscent of what we like in the Dyson air purifier combo: a touch of futurism. The key difference here is that the EverestAir not only looks good, but it also does a fantastic job at cleaning the air. Point for Levoit.
Most high CADR air purifiers have to be big so that they can house the enormous fan. But the engineers at Levoit have managed to provide large CADR in a smaller body. Just to give you an idea of size, we took a photo comparing the EverestAir against the powerful IQAir Healthpro Plus:
The Levoit EverestAir has a much more manageable size, yet it performs at a high level. But I have to say that this is not a small unit. The good news is that Levoit gave it wheels to make it easier to move from room to room:
With the EverestAir, Levoit has brought the Apple design aesthetic everyone knows and loves to the world of air purifiers.
I particularly like the combination of a white front panel with silver for the main body and the black glass-effect plastic used for the control panel:
In terms of the controls available in the EverestAir, from left to right, you get touchscreen buttons for sleep mode, auto mode, turbo, fan speed, fan angle, timer and on/off button.
In the middle of the panel, you will see a screen where you can display filter info (filter life % so you know when it’s time to replace the filter) and also air quality information (PM1, PM2.5 and PM10 particles in the air).
That’s right. Air quality info on your display.
The EverestAir comes with a three-channel laser sensor that detects dust particles of PM1.0, PM2.5 and PM10.
We were impressed by how quickly the screen changed when we started burning incense next to it to release pollutants into the air. When we turned on the unit, we could quickly track the speed at which the EverestAir was cleaning the air:
The best part? The air quality sensor in the Levoit EverestAir matched what we could see in our trusted PurpleAir Indoor Sensor, which uses an industrial-grade particle sensor. 👏👏👏
Before I move on to discussing air filtration technology, I have to mention the Levoit VeSync mobile app. It is super handy to be able to add my new EverestAir to my already existing account, allowing me to control the settings of this unit in addition to all the other Levoits I’ve got placed in different rooms around my house:
Filters that can deal with anything
Like other filters from Levoit, the 3-stage filtration technology in the EverestAir combines a washable pre-filter, a main filter and pelleted activated carbon.
This large filter can deal with both pollutants and smells:
One side of this filter features a high-quality main filter to tackle the tiniest airborne particles:
The other side features a honeycomb activated carbon filter:
I was very impressed by the filter’s size, quality and amount of activated carbon.
For tackling odors or chemicals, you need a good amount of carbon in your air purifier’s filter, so it is great to see such a large quantity of activated carbon pellets included in the EverestAir’s filter.
Just to show how big the filter is, I took a comparison photo showing the size difference between the EverestAir and the IQAir HealthPro Plus:
During our performance test, we saw that the VOC levels were reduced much quicker than units with smaller levels of carbon: the EverestAir brought VOC levels back to baseline in 160 minutes — it takes many other air purifiers most of the day to achieve this.
Changing the filters on the Levoit Everest is easy as they are accessible from the front. You can see how easy it is in our video below:
As with all brand-new air purifiers, the filters for the EverestAir will come in plastic bags. Make sure to remove them before you switch them on, or they won’t be able to do anything to remove pollutants from your air.
The EverestAir cleared our test room in 14 minutes
As with all the air purifiers we review here at HouseFresh, we timed how fast the Levoit EverestAir could remove incense smoke particles from the air in our home lab.
In our 728 cubic ft home lab, we simulate particle pollution and VOCs with an incense stick and use a Purpleair Indoor Sensor to monitor particulate levels. We then activate the air purifier at its maximum speed and measure the duration required to reduce the room’s air quality to a PM1 level of zero.
This is what happened when we performed this air cleaning test on the Levoit EverestAir:
The results we saw with the Levoit EverestAir blew us away. We repeated the test three (3) times because we couldn’t believe what we were seeing.
Air cleaning performance test results
We expected good results with a CADR of 360 CFM but assumed it would be the same as the Alen BreatheSmart 75i at 24 minutes and certainly not faster than the Levoit Core 600S.
But we were delighted to see even better air cleaning performance results than the CADR we expected:
I didn’t stop there. In addition to testing the air cleaning performance when running at its top fan speed, I also ran the test at the lowest fan speed, and the EverestAir delivered: this air purifier cleared all traces of incense smoke in our test room in just 25 minutes.
When comparing the EverestAir against all of the other Levoit air purifiers we have tested, you can see how it clearly defeats most of them when it comes to air cleaning speed, only outbeat by the Smart Air Blast Mini (12 minutes):
For those with larger rooms or large ceilings, the EverestAir will be more than capable of keeping the air clean. However, I would still push for a specialist air purifier for significant issues like VOC or chemicals like the AustinAir Healthmate, as they have much larger carbon filters,
Noise levels test results
It hits up to 57.8dB using the Turbo mode but is much quieter at the lower fan speeds, going as low as 39.1dB, which sounds like no noise to my ear.
Don’t just take our word for it, have a listen for yourself as we go through the different fan speeds in the video below:
The cost to run an EverestAir: $173.57 per year
The cost to run the Levoit EverestAir is similar to other large air purifiers like the Blue Pure 211+ and Alen 75i
1. Electricity costs = $73.58 per year
Energy costs always seem to go up, so it’s essential to be aware of the long-term costs as air purifiers, in most cases, will be run continuously to keep the air clean. The Everest hit 69.8 watts using its turbo at the highest speed and went down to 9.85 watts at the lowest fan speed.
The energy usage is higher than that of other smaller units, but it makes sense when you consider the performance. It compares well with similar big units like the IQAir Healthpro Plus, which pulls a whooping 145.2 watts.
When comparing wattage usage to performance, the EverestAir is one of the most efficient air purifiers on the market.
2. Filter costs = $99.99 per year
Many smaller air purifiers need their filters replaced every six months, so they can quickly add up to nearly $100 per year. While the filters for the EverestAir are not cheap, considering you can replace them every 12-15 months, the cost is very much in line with even the budget air purifiers we recommend.
This chart shows how the costs stack up against other Levoit air purifier filter replacement costs:
As of writing this review, you can get two filters for under $99.99 if you don’t get the genuine ones from Levoit, bringing costs down to nearly $65.98 per year.
Bottom line
As of August 2023, we have a new HouseFresh Best Air Purifier award winner.
Levoit has been creating very efficient air purifiers that perform well for a reasonable price, and it makes sense that they would create something for the premium market.
You will get more power for your money with the Levoit Core Series, but the EverestAir beats them hands down for looks. We tested running this air purifier at the lowest fan speed, and it still cleaned our room in 25 minutes at 39.1 dB — which was silent to my ear.
It’s an easy air purifier to live with, but it doesn’t come cheap.
SOURCES
We calculated yearly costs associated with running the Levoit EverestAir 24 hours a day, 365 days per year utilizing the Appliance Energy Calculator developed by the U.S. Department of Energy using the national average of of $0.12/kWh as of June 2024.
