Levoit EverestAir: Is This High-End Purifier Worth It?

Full Review

The Levoit EverestAir is a large air purifier with a CADR of 360 CFM (612 m³/h), placing it firmly in the category of devices designed for large rooms.

Although it’s rated for spaces up to 558 sq. ft. (52 m²), I believe it can handle slightly larger rooms as well—something our tests have confirmed.

Its many smart features, including an air quality sensor, auto mode, and smart app support, are just some of the standout features this purifier offers.

However, the somewhat higher initial price may be a barrier for some buyers. Keep reading to see how it performed in our tests and whether it’s worth the investment.

How We Tested the Levoit EverestAir?

1. For the filter efficiency testing, we used the Temtop LKC-1000S laser particle meter, which measures PM2.5 (µg/m3), PM10 (µg/m3), Particles (per/L), and HCHO (mg/m3) in the air, and also calculates the AQI.

2. We placed the Levoit EverestAir in a 560 sq. ft. (52 m²) room. Then, we recorded the initial air quality values using the Temtop laser particle meter and let the Levoit EverestAir run at maximum speed.

3. After 60 minutes, we measured the new values using the Temtop laser particle meter and saved the data.

4. Next, we placed the Levoit EverestAir in a glass box, which we then filled with smoke. Then, we measured how much time was needed for the air purifier to remove all the smoke from the box.

5. Using a special noise measurement tool, we tested the air purifier’s noise level at all speeds. We measured the noise level on the dBA scale.

6. Finally, we measured the power usage at all speeds using an energy meter, after which we calculated how much it would cost to use the device at a particular fan speed for one month. For reference, we used an energy price of $0.12 per kWh.

The Levoit EverestAir is a massive air purifier—one of Levoit’s largest models, right alongside the Core 600S.

With a CADR of 360 CFM (612 m³/h), it offers large coverage, making it ideal for open spaces and larger rooms.

It uses rectangular filters, features an easy-to-clean pre-filter, and has adjustable air vents. All these features contribute positively to its overall efficiency.

We tested its performance in two different rooms, and I’ve also used it in my own home. What stood out to me is that the Levoit EverestAir is a true beast—one of the “fastest” air purifiers I’ve tried. It improves air quality in a matter of seconds.

Testing in a 560 sq. ft. (52 m²) Room

We placed it in a 560 sq. ft. (52 m²) room, which is almost exactly the size this air purifier is recommended for — making it a perfect test environment.

In just 60 minutes, running continuously at maximum speed (Turbo mode), the Levoit EverestAir improved air quality by 96%. We measured the results using a Temtop laser particle meter.

Compared to other air purifiers with similar CADR, the Levoit EverestAir ranks very high (see the chart). For example, the AirFanta 3Pro also achieved a 96% improvement in the same room.

However, the Levoit Vital 200S reached a 92% improvement under identical conditions.

Overall, I would say the Levoit EverestAir is a highly efficient air purifier that can drastically improve the air quality in your space, almost instantly.

When it comes to noise, one thing I really like about this model (and many other Levoit purifiers) is that it offers five fan speeds plus auto mode.

Considering its CADR, I’d say it’s very well optimized for noise.

At the lowest speed, the Levoit EverestAir produces 40.1 dBA, which is quite good — ideal if you plan to use it in a bedroom or any quiet space.

At the maximum speed, it reaches 63.2 dBA. That’s noticeably louder, but still within the range of similar air purifiers. For comparison, the Levoit LV-H134 hits 70.3 dBA at max speed, which is too loud in my opinion.

I’d also point out the Levoit Core 400S, which is exceptionally well-optimized at maximum speed. It produces only 59.9 dBA, though it also has a smaller CADR than the EverestAir.

Overall, I’d say the Levoit EverestAir is well-optimized for noise, especially when you consider its CADR-to-noise ratio.

When it comes to power consumption, the Levoit EverestAir uses a 70W motor but delivers a large CADR.

Still, I’ve seen several air purifiers with smaller motors that achieve similar or even higher CADR values than the EverestAir.

If you were to run this air purifier at maximum speed, 24 hours a day for an entire month, your electricity bill would increase by about $5.34, which actually places it relatively low in terms of operating cost compared to similar models.

For example, the Blueair 311i Max would cost only $2.42 under the same conditions.

In addition to electricity costs, there’s also the expense of replacement filters, which need to be changed approximately every 12–15 months. To be honest, the EverestAir’s replacement filter is slightly more expensive than those for comparable air purifiers.

In conclusion, I think Levoit could optimize the EverestAir a bit more. Keeping the high CADR while lowering the motor’s power consumption and reducing the price of the replacement filter would make it an even better overall package.

Filtration Technology

The Levoit EverestAir uses a rectangular filter located behind the front panel of the device.

It relies on a three-stage filtration system consisting of a pre-filter, a main filter, and an activated carbon filter.

The EverestAir doesn’t use an ionizer or any filtration technology that could potentially generate ozone, making it completely safe to use.

All of its filters are high quality, which is confirmed in our performance tests.

Pre-filter

The pre-filter is the first stage of filtration. It’s a washable filter that looks similar to a mosquito mesh.

This filter doesn’t need to be replaced unless it gets damaged.

It captures larger particles such as dust, lint, fibers, hair, and pet fur. By doing so, it extends the life of the main filter and improves overall filtration efficiency.

I recommend cleaning the pre-filter at least twice a week — or even more often if you use the EverestAir in a home with pets.

Main Filter

The main filtration stage, the particle filter, is the second layer of filtration and the most important one in this air purifier.

This filter captures small airborne particles such as dust, pollen, mold spores, smoke, and similar.

It removes PM2.5 particles and even smaller particulate matter, helping keep the air in your home safe from tiny, invisible contaminants.

Activated Carbon Filter

The final filtration stage is the activated carbon filter, which is pellet-based and contains 400 g of carbon pellets.

This filter effectively adsorbs bad odors, VOCs, smoke, and similar pollutants.

In our tests, it performed well in removing smoke and unpleasant odors, but I believe it would do even better with a larger amount of carbon. In fact, some smaller Levoit air purifiers use the same, or a very similar, amount of carbon pellets.

How to Replace the Levoit EverestAir Filter?

I’ve already explained how the filter info feature works, so I won’t repeat it in detail again.

It’s essentially a filter reset indicator that notifies you when it’s time to replace the main and activated carbon filter combo, which is typically every 12–15 months.

However, I strongly recommend cleaning or washing the pre-filter at least twice per month, or even more often if you’re using the air purifier in a home with pets. This helps maintain optimal filtration performance and extends the lifespan of the other filters.

Setup and Installation

The Levoit EverestAir comes almost ready to use. Even though the filter is already installed inside the device, you still need to prepare it before first use.

Remove the filter from the unit, take off the plastic packaging, and place the filter back inside.

Next, connect the power adapter to the back of the device, place the air purifier in your desired location, plug it in, and turn it on. That’s the entire setup procedure.

P.S. Never block the air inlets or outlets, as doing so can restrict airflow and potentially damage the motor or the purifier itself.

Design

Frankly, this is the best-designed and most modern Levoit air purifier I’ve tested, and I’ve bought and tried almost all of them.

It’s made of high-quality plastic, the finish is excellent, everything fits perfectly, and overall, the build quality is outstanding.

The EverestAir is white on the front, with silver details on the back, and features a black control panel and top air outlet vents.

It’s a robust device, weighing 20.3 lb (9.2 kg), but fortunately it has wheels on the bottom and a slot at the back, making it easy to move from room to room.

Although the EverestAir’s design somewhat resembles Levoit’s Vital series, I still think the EverestAir looks more modern and is built with higher-quality materials than most other Levoit air purifiers.

Controls and Indicators

At the top of the device, you’ll find the control panel, which includes all the essential controls and indicators.

The touch-sensitive buttons are easy to use and well-placed. Here, you’ll find buttons for power, sleep mode, auto mode, turbo mode, air info, filter info, fan speed, vent angle, and the timer.

In addition, the panel displays air-quality indicator rings, real-time air-quality data, and the filter wear percentage. There’s also a Wi-Fi indicator.

Overall, the control panel is advanced, but I still recommend connecting the EverestAir to the VeSync smart app for the best experience.

Airflow

The Levoit EverestAir pulls air in through the openings on the front cover.

The air then passes through the three-stage filtration technology and exits through the fan grilles on the top.

I have to point out that I really like the air outlets on this model. They’re adjustable louvers that allow you to tilt and direct the airflow however you prefer.

You can choose between vent angles of 45º, 60º, 75º, and 90º. By default, the vents are set at a fixed 75º angle.

This is an extremely useful feature, especially for a large air purifier like this. You don’t need to move the entire device if the airflow direction isn’t ideal; just adjust the clean-air outlet angle and you’re good to go.

Size and Dimensions

The Levoit EverestAir is a truly massive air purifier; it takes up noticeably more space than something like the Levoit Core 600S.

Its dimensions are 18.9 × 8.5 × 24.5 inches (48 × 21.6 × 62.2 cm), and it weighs 20.3 lb (9.2 kg).

Although it’s not a lightweight or compact purifier, I like that it comes with wheels on the bottom. Unfortunately, they’re fixed, which means you can only roll the device left and right in a straight line.

What’s in the box?

When you purchase the Levoit EverestAir, you will get 1x device, 1x pre-installed filter, a user manual, and a power adapter.

Features Overview

The Levoit EverestAir comes with plenty of smart features, which I’ve already mentioned a few times.

These features not only make everyday use easier but also provide useful air-quality insights and allow you to automate the device’s operation.

Air Quality Sensor & Indicator

The Levoit EverestAir uses the AirSight Plus™ 2.0 laser dust sensor, which is a three-channel sensor capable of measuring PM1.0, PM2.5, and PM10 particles.

The sensor is located on the side of the device and detects particles in real time. Importantly, it’s working even when the air purifier is turned off, allowing you to check air quality at any time through the VeSync smart app.

It also integrates with other features such as Auto Mode, the air-quality indicator, and the smart app to deliver a fully automated experience.

On the display, placed at the center of the control panel, you’ll see the “clean air percentage,” an algorithmic estimate of overall air cleanliness.

Indicator Color	Clean Air Percentage Range	Air Quality	Auto Mode Fan Speed
Blue	90–100%	Very Good	Sleep Mode
Green	80–89%	Good	Low
Orange	70–79%	Moderate	Medium
Red	0–69%	Bad	High

By pressing the Air Info button, you can switch the data shown on the screen to view PM1.0, PM2.5, and PM10 concentrations (µg/m³).

Additionally, the ring around the display changes color based on the current air quality.

Overall, it’s a fantastic feature set, especially for anyone who wants automation and clean air with minimal effort.

Auto Mode

Auto Mode is another feature that works in combination with the air-quality sensor.

When activated, the air purifier automatically adjusts the fan speed based on the current air quality in the room. If the air becomes more polluted, the purifier increases the fan speed; as the air quality improves, it lowers the speed again.

Keep in mind that the Levoit EverestAir does not use Turbo Mode while operating in Auto Mode.

Sleep Mode

When switched to Sleep Mode, the air purifier lowers the fan speed to its minimum and dims all display lights within six seconds.

The only light that remains on is the filter indicator, but only when it’s time to replace the filter.

Light Sensor

This sensor simply detects the amount of light in the room. If the room is dark, it automatically dims all the indicators on the device.

Additionally, if the air purifier is running in Auto Mode and the room is dark, it won’t switch to Speed 3 or Turbo Mode.

Filter Info

The filter indicator lights up when it’s time to replace the old filter. This is typically between 12 and 15 months, but it depends on your environment and how often the purifier is used.

If you want to check the current filter wear, you can do so through the smart app or by pressing the Filter Info button, which will display the remaining filter life percentage.

Timer

The timer is a useful feature, though I believe many users won’t rely on it often since the VeSync app offers a far more advanced timer and scheduling options.

The built-in timer works by letting you choose how long the device should run before turning itself off. You can set it anywhere between 1 and 12 hours.

Warranty

The Levoit EverestAir comes with a two-year warranty.

To ensure you receive full warranty protection from Levoit, I strongly recommend registering your device directly on Levoit’s website.

VeSync Smart App

I’ve explained the VeSync app many times — in fact, in every review where I covered a Levoit air purifier with smart features, I described how the app works.

And the key point hasn’t changed: the VeSync app is still one of the best on the market.

Connecting the Levoit EverestAir to the VeSync app is simple, and the benefits you get afterward are significant.

Once connected, you gain access to a completely new level of control.

First and most importantly, you can remotely control the device from anywhere. You also get more detailed, visually appealing, and historical air-quality data.

In addition, the app lets you adjust Auto Mode sensitivity and advanced scheduling, timers, voice control, and much more.

I’ll say it again: connecting the Levoit EverestAir to the VeSync smart app is a must.
