Levoit EverestAir air purifier: two-minute review

Air purifiers designed for large rooms tend to be big and bulky – but the Levoit EverestAir Air Purifier is an exception to that rule. It's a slim machine that can fit into tight spaces, and fit flush against a wall, but which packs enough power to use in extra-large spaces.

Inside, you'll find a 3-stage filtration system that includes a washable pre-filter, and a H13 True HEPA filter and an activated charcoal filter combo. I have an open plan home with no walls separating the living room and kitchen, and the EverestAir did an excellent job of purifying the space quickly and effectively, including clearing my neighbor's cigarette smoke. In fact, this is one of the most effective air purifiers I've ever reviewed – and I've tested over 50 of the best air purifiers on the market.

The mode I used most often was Auto, where a laser dust sensor scans for airborne particles and increases or decreases the fan speed as necessary. There's also a Sleep mode and a Turbo mode.

The control panel includes plenty of options, but they're clearly presented and the information is easy to navigate and digest. The air quality score, along with color-coded rings, provide you with an at-a-glance overview. At the touch of a button, you can also cycle through readings for specific particulate matter, such as PM 1.0 (fine dust and microtoxins), PM 2.5 (dust, smoke, and pet dander) and PM 10 (pollen, ash, and airborne allergens). There's no remote control, but you can control the EverestAir from a distance using the companion app, which includes options to turn the device on or off, switch modes, create a schedule and more.

Normally, the airflow on an air purifier is in a fixed position. However, the Levoit EverestAir has adjustable vent angles, which is ideal for directing the clean air to suit the position of the purifier. Cleverly, when the air purifier is not in use, the vents close completely to keep dust out.

That's the short version – read on for my full Levoit EverestAir review.

(Image credit: Future)Levoit EverestAir review: price & availability

• List price: $499
• Available: US

The Levoit EverestAir has a list price of $499.99 and is available to purchase direct from Levoit US via Amazon. While Levoit does have a presence in the UK and Australia, at time of writing this model wasn't available in either territory.

The Levoit EverestAir replacement filter is rather expensive ($99). However, it only needs to be replaced every 12-15 months with normal use… so you could think of it like a $50 filter that needs to be replaced every 6 months, if that helps.

In the air purifier market, the Levoit EverestAir is considered a mid-range purchase. It's more expensive than the Levoit Core 300S, which is TechRadar's top budget air purifier choice. On the other hand, it's significantly less pricey than the likes of the Dyson Purifier Big+Quiet Formaldehyde BP04. For me, the features, functions, and build quality certainly justify the price, and it delivers strong value for the money.

Levoit EverestAir review: design

• Sleek, compact design with easy filter access and wheels for moving
• Vents can be angled to suit the position of the purifier
• Can be controlled via touchscreen buttons, a companion app, or voice

Air purifiers can be bulky, but the Levoit EverestAir Air Purifier has a sleek design that's less than 9 inches / 22.9cm wide. When I'm working at my desk, it's usually positioned in the tight space between my desk and sofa.

The EverestAir has a white front, stainless steel back, and black top, and the design is unique enough that visitors to my home often point to the machine and ask what it is. (For context, I also have a TruSens air purifier that looks like a speaker, and a Bowers & Wilkins Zeppelin speaker that looks like a football, so you can understand how it's easy for guests to get confused.)

As well as looking stylish, it's very functional. Levoit has added wheels underneath, which make it easy to roll the whole thing around (it weighs 20.7lbs / 9.4kg, so it's not really heavy, but I wouldn't want to pick it up). Some purifiers have to be turned upside down to access and remove the filter. However, with this air purifier, I merely need to gently pull the panel door and it comes off immediately.

I also appreciate the fact the vents are adjustable, enabling me to customize my airflow. By touching the Angle icon, I can choose to set the vent angle to 45 degrees, 60 degrees, 75 degrees or 90 degrees. So if I put the air purifier under my kitchen island, I can angle the vent so the clean air flows out and away from the island rather than blowing upwards into the bottom of the countertop.

(Image credit: Future)

On the top of the purifier you'll find a touchscreen control panel. With white text and icons on a black background, the display panel is clear and easy to read, and the contrast is sharp enough that the items are visible in bright light as well as no light. On the left hand side of the panel, you'll find options to toggle between three special modes (Sleep, Auto and Turbo), as well as buttons to access 'Air info' and filter info. To the right of the control panel are the controls for speed, vent angle, and the timer function, as well as the on/off button.

Of course, you don't have to use the touchscreen panel for control if you don't want to. You can also adjust settings using the companion app, where you'll find options to turn the purifier on or off remotely, change the mode, create a schedule, explore air quality, or check on remaining filter life. There's also support for voice control via Amazon Alexa or Google Assistant.

Levoit EverestAir review: performance

• User-friendly display with useful information
• Cleans air quickly and effectively, even in large spaces
• Auto mode works well to detect pollutants

One unique feature of the Levoit EverestAir is that it provides a clean air score as a percentage. The air purifier works this number out based on the concentration of particles and changes in detected particles during the purification process. Keep in mind that the clean air percentage is based solely on particles, not odors or gases. Typically, in my home, the score is between 98% and 99%.

By default, the Air Info button displays the clean air score as a large percentage, in the center of the control panel, and surrounded by rings that are color-coded to indicate air quality. The ring is blue when the air quality is very good, green when it's good, orange when the air quality is moderate, and red when the air is bad.

Press the Air Info button again and it'll show you PM (particulate matter) information. One press shows PM 1.0 (fine dust, micro-toxins), a second press shows PM 2.5 (dust, smoke, pet dander), and a third press shows PM 10 air info (pollen, airborne allergens).

(Image credit: Future)

When the air purifier is in Auto mode, it will automatically detect a change in the air's quality and boost or lower the airflow in response. There have been plenty of occasions where I've noticed a change in fan speed, looked down to see what was happening, and noticed that the air quality indicator rings had turned orange. That usually means my neighbor is smoking, and the air purifier is working hard to clean my air.

The Levoit EverestAir does an excellent job of removing pollutants from the air. That's due, in part, to the combination of filters. The washable pre-filter captures dust, lint, hair, and pet fur. I love to see pre-filters on an air purifier, because they help to extend the lifespan of the filter.

Behind the pre-filter is the H13 True HEPA main filter, and it is designed to trap such pollutants as fine dust, smoke, pollen, and pet dander. Lastly, the high-efficiency activator carbon filter is what makes the air smell so clean. The carbon absorbs smoke, fumes, and odors, ranging from secondhand smoke to smells from food and pets.

(Image credit: Future)

The average air purifier has a CADR (clean air delivery rate) in the 200 range. However, the Levoit EverestAir has a much higher CADR: 354 CFM (cubic feet per minute). In my bedroom, the air purifier can clean/change the air around 5 times per hour when it's on the highest setting and my bedroom door is closed. In the living room, which is open to the kitchen and the steps leading downstairs, it cleans the air around twice an hour.

The Levoit EverestAir does an excellent job of clearing odors. This is due, in part, to the activated carbon filter, which is specifically designed to absorb odors. One pleasant surprise I discovered as I was testing: most air purifiers have to be set on high to clean the air and remove odors. However, even on a medium setting, the Levoit EverestAir effectively cleans the air.

For the purposes of this review, I recorded how long it took for the purfier to clear the smell of second-hand smoke in various spots in my home. It completely removed smoke from my bedroom in roughly 10 to 12 minutes, and took 20-30 minutes to clear the smell from my large, open-plan living space.

(Image credit: Future)

Don't let anyone fool you. Air purifiers on high tend to be noisy. On Turbo, this one gets quite loud as well – although not as loud as many others that I've tested. The noise level ranges from 24db on the lowest setting to 56dB on the Turbo setting.

If you're looking for a setting that creates minimal disturbance, you'll want to activate Sleep mode. This turns off the display and uses a fan speed that is lower than the Low speed. It's great for people who like to keep the air purifier running all night, but are easily bothered by lights and noise. However, I tended to use a higher setting overnight.

As a general rule, I'm quite happy to manually operate the control panel on the top of the machine. However, for testing purposes, I also downloaded the app to my smartphone and controlled the air purifier by this method. The app was easy to set up and integrated seamlessly, providing the same level of control as the touch controls.

Regarding maintenance, every two to four weeks, I've wiped the exterior with a dry cloth, and vacuumed the pre-filter. On other occasions, I've also rinsed the pre-filter in the sink, and washed it with a damp cloth and liquid detergent. Every three months I use the vacuum cleaner attachment to clean the dust sensor on the side of the air purifier.

The process for changing the filter is really easy and entails removing the front cover, removing the old filter, cleaning any dust or hair with a vacuum hose, and inserting the new filter.

Buy it if...

You want a purifier you can tuck out of the way

The Levoit EverestAir Air Purifier has a slim design that doesn't take up much space, and it can fit into tight spaces and still work effectively. Also, since the vents are adjustable, you can angle them so the clean air is directed out into the room.

You want a purifier for a larger space

The Levoit EverestAir has a higher-than-average CADR (clean air delivery rate) to quickly remove pollutants from the air, and the pre-filter, HEPA filter, and activated charcoal filter combine to trap particles of various sizes.

You want something you can control from afar

The EverestAir can be controlled remotely, via the companion app, and it's also possible to set a schedule. If you're in the same room, there's support for voice control.

Don't buy it if...

You have small kids

Admittedly, many air purifiers may not be ideal to use around curious toddlers and small kids. My primary concern with the Levoit EverestAir is the adjustable vents, since their tiny fingers may get caught in the vents if they accidentally tap the adjustment button.

You're on a budget

While there are plenty of air purifiers that cost more than the Levoit EverestAir, there are also cheaper and simpler options that might be absolutely fine if you're on a budget or only need something for a relatively small space.

You want something simple

The Levoit EverestAir is very user-friendly, but there are nine different items on the display panel. Not everyone wants that level of insight or control – and there are plenty of simpler options if that includes you.

How I tested the Levoit EverestAir purifier

I've been using the Levoit EverestAir in my home for the past two years and 5 months. My house was built in 2016 and includes an open living room/kitchen and two bedrooms, and a HVAC system. During this time, I've used the EverestAir in the living room/kitchen to clear cooking smells and second-hand smoke from my neighbor. I’ve also used it – to great success – in my bedroom.

For this review, I made note of how quickly it responded to and cleared pollutants. I also explored all the various special modes and control options, including digging into the companion app. I compared my findings to other air purifiers I've tested – I've reviewed over 50 different models in my years as a consumer tech journalist – to get a feel for how it compares to the wider market and if it offers good value for the money.

• First reviewed October 2025

After more than two years of use, I'm still impressed by the Levoit EverestAir's ability to clean air efficiently and get rid of odors.

To me, as a video editor, being able to shoot, edit, and share a short film all from a small handheld device has always been these slabs of glass’ revolutionary concept. I’ve been editing and experimenting with them since I downloaded iMovie for the iPod Touch.

Since then, I've tested out all the best video editing apps, with some focusing on simplicity, while others try to cram a desktop video editor into a phone. There’s truly something for everyone. Even Adobe was on the scene with Rush.

But there's a new Adobe app in town that, I think, might be a massive game-changer for creators on the go. Adobe Premiere, also known as ‘Premiere on iPhone’, likely to differentiate it from its desktop big brother, Premiere Pro.

Adobe Premiere on iPhone: Pricing & plans

• Most tools are free. What isn’t are the AI features and online storage, but if you already have a subscription with Adobe, it’s possible it could now include this new app, meaning you won’t have to fork out more of your precious money to take full advantage of Premiere.

Competing in the mobile market is hard, what with most apps being sold for so little… How can you expect to make a profit? That doesn’t seem to be too much of a concern for the mighty Adobe, as they’ve released Premiere on iPhone for free (henceforth just referred to as Premiere for simplicity). You can download it by clicking here.

Yes, there are in-app purchases in the form of monthly and annual subscriptions. These unlock some features on the app, including online storage, and likely a certain number of generative credits each month.

Do be aware however that these unlocked features can also be accessed simply by login into your Adobe ID, and if you already subscribe to one of their other plans, you might not even need to pay for an additional subscription.

For instance, I have access to the Creative Cloud All Apps package, and I’ve encountered no limitation in my use of Premiere. I realise this is quite nebulous: as of this writing I haven’t received a response from Adobe about what you get with a Premiere Mobile subscription, and which other subscriptions grant you the same access to this new app.

Adobe Premiere on iPhone: Interface

(Image credit: Adobe // Future)

• An excellent, well polished interface, which makes it easy to control, while getting out of your way when editing, letting you see only what you need to see, when you need it.

Although Adobe refers to this app as ‘Premiere on iPhone’, it’s a bit of a misnomer as it’s also designed to work perfectly on iPad. Sorry Android users, you’ll have to wait a little longer for yours; it’s coming, but it’s just not quite ready.

On iPhone, just like Rush was, you’ll be working exclusively in portrait orientation. The iPad is way more flexible, and the interface will work in either portrait or landscape.

When you first launch the app, you’ll be greeted with a handful of tutorials, and a series of 8 icons at the top of the screen. Any project you’ve worked on will appear beneath them, represented by large thumbnails.

These icons allow you to start a new project, either one from scratch, or by choosing some clips from your Photos library. You also have dedicated tools, like being able to extract audio from a file, adding captions, or even access AI tools such as generating an image, turning a photo into a video, or expand an image beyond its original borders.

Once you’re working on a project, the screen is divided into two parts. The top section is for a Preview of your film, and the lower part represents the Timeline. There’s a very handy slider to the left which lets you resize both sections, which is a very clever addition, especially when your project becomes very complex with multiple layers, and you need to see all of them to fine tune your edit.

At the bottom is a contextual toolbar: by default, this is where you get to add additional video clips, audio files and titles. Tap on a clip in the Timeline, however, to reveal adjustment tools instead; tap on an edit point to see a paltry number of transitions. It’s a simple concept: you only see the tools you need when you need them.

You’ll also find a handful of icons at the top of the screen, and perhaps the most interesting one offers you various aspect ratios for your project. By default, it’ll take on the format based on the first clip you add to it, but if this isn’t right for you, this button enables you to override that.

Overall, the interface is simple, uncluttered and clean, and allows you to control your project with ease.

• Score: 4.5/5

Adobe Premiere on iPhone: Video editing

(Image credit: Adobe // Future)

• The interface is designed to make editing easy and fluid, and it works great, offering you surprising frame-accurate precision, whether you’re on an iPad or iPhone.

Editing is really nice and fluid. You can effortlessly zoom in and out of your project, select a clip, trim it, move it around, the works. I did mention when the app was announced, that it felt a lot more like Apple’s Final Cut Pro (FCP) than Adobe’s desktop Premiere Pro. The clips’ rounded look for one.

The fact clips reorder themselves when you drag one to another location, reminded me very much of Final Cut’s magnetic timeline. I’m obviously biased as I love the magnetic timeline, as it allows you to edit much quicker in my opinion, and here, it makes it so easy to work using only a finger or two. Also, just like FCP, the layers aren’t numbered; new ones appear as you need them. Good to see Adobe being comfortable with being inspired by its competitors, for the benefit of its users.

When it comes to altering clips, you have a handful of tools at your disposal. With them, you can change their speed, reverse them, alter their opacity, create a freeze frame, or perform some colour correction, among others. It’s all done through icons and sliders, and that interface resize tool I mentioned earlier to see more or less of the viewer and timeline, works great for this too, as you can see those parameters, your Timeline and the Viewer all at the same time, even on an (large) iPhone.

Some tools, such as Transitions and Adjust also have an ‘apply to all’ button which greatly speeds up your workflow if you wish to paste the same effects across the board. It’s impressive and very well done. Working with Premiere was slick and smooth, even on a 7 year old iPhone XS.

• Score: 4.5/5

Adobe Premiere on iPhone: AI

(Image credit: Adobe // Future)

• A good selection of AI tools which, along with the usual generative text prompts, are designed to enhance your project in useful and creative ways, especially the ‘generate sound effect’ one.

A sleek interface is already a big plus, and you get that for free, without having to log in to or create an Adobe ID. But if you don’t mind opening your wallet, or if you’ve already got an eligible subscription, then Adobe offers a string of very impressive tools, most based on some kind of AI.

Take ‘Enhance Speech’. It’s designed to improve the quality of spoken audio if you recorded something with a lot of background noise. It works extremely well, enriching the quality of the spoken audio immensely. You’re also offered a couple of sliders so you can choose how much of the background noise to keep.

You also have the ability to generate images and stickers, but perhaps the most impressive AI tool is ‘Generate Sound Effect’. On the surface, it looks like any other AI feature: you’ve got a text prompt where you input the description of what you hope to get, but what sets it apart is the optional extra: you can use your voice to ‘perform the sound’, and the AI will base the effect on your performance. It works surprisingly well, and could become quite addictive.
