IQAir Atem X: two-minute review
I’ve had the IQAir Atem X Air Purifier since April 2024 – and it has never once disappointed me. The real standout is the design. This sleek, stylish Swedish air purifier looks like something you’d find in New York’s Museum of Modern Art (MoMA). It’s large, but the fact you can place it flush against the wall means it won’t get in the way.
Since I have a smoking neighbor, I take air purifiers seriously, and often I’ve wished I had more than 3 or 4 speeds to choose from. The IQAir Atem X has 8 speeds, so I can always find the most effective speed that’s not so loud enough that I need to wear ANC headphones. It also boasts much higher-than-average CADRs (clean air delivery rate), which make it suitable for use in large spaces.
The purification uses ‘HyperHEPA’ filters (ed’s note: I’m confirming if this is true HEPA, but will assume not) and ‘impactors’ (equivalent to pre-filters). I have an open plan home, so there are no walls to separate the living room and kitchen, but the IQAir Atem X removes my neighbor’s tobacco smoke, and my occasional kitchen odors, very efficiently. This is even more impressive considering there’s no activated charcoal filter. It’s really hard to believe that something so beautiful can work like a beast to remove odors so quickly.
You can control the Atem X using the touch controls that sit on the back side of the purifier but are still very easy to access, or via a useful companion app. However, there’s no voice assistant support for those who prefer to go completely hands-free.
The main sticking point for many people will be the price. This is a very expensive purifier, and the replacement filters don’t come cheap, either. However, if you want something functional and beautiful, and are happy to invest to get it, it’s an excellent choice. So, that’s the short version – keep reading for my full IQAir Atem X review.
IQAir Atem X review: price & availability
- List price: $1,399
- Available: US online, various other countries via dealers
The IQAir Atem X is available to buy online in the US from the IQAir website or through Amazon. At listing value it prices $1,3999. It’s additionally obtainable in varied different nations, however usually through sellers.
The air air purifier makes use of three HyperHEPA filters at a time, and the alternative pack is $199, which is among the many most costly filters I’ve ever encountered. Fortunately, the filter pack solely must be changed yearly if you happen to’re utilizing the air purifier commonly, or perhaps much less usually if it is not getting used as a lot.
In the air air purifier market, the IQAir Atem X is taken into account a premium buy. It’s considerably costlier than my favourite air purifier, the Levoit EverestAir, which has an inventory value of $499.99 and is comparable in efficiency. Price-wise, the IQAir Atem X is similar to the Dyson Purifier Big+Quiet Formaldehyde BP04, which retails for $1,199.99 on the time of publication.
The IQAir Atem X is an especially good air air purifier, and the assorted capabilities, user-friendly options, and high quality construct assist justify the worth. However, it’s extremely costly – and particularly if you happen to issue within the ongoing price of filters – and might not be in everybody’s price range.

IQAir Atem X review: design
- Stylish, minimalist design with recessed touch controls and smart controls
- Pre-filters and ‘HyperHEPA’ filters, but no activated charcoal filter
- Adjustable airflow
The AQAir Atem X Air Purifier is large, but it doesn’t look bulky. That’s because it has a slim, minimalist design. In fact, I think this air purifier looks like a work of art; something you’d see at New York’s MoMA. I love appliances that aren’t easily identifiable, and the Atem X definitely falls in this category. Guests always ask what it is – especially since there are no controls on the front.
IQAir is a Swiss company, and the air purifier is actually made in Germany. The Atem X reflects Swiss design sensibilities in the clean lines and uncluttered look. For example, the power cord is retractable, so any excess can be hidden. Also, the front of the air purifier is completely free of controls – they’re located in the back, and also recessed, so even from a back view, they’re unobtrusive.
The Atem X comes with a detachable wheel base, which makes it easy to transport, but is the only part of the air purifier that looks clunky. I’ll be honest with you here: the wheel base is somewhere in my garage and I couldn’t locate it for the review. Because I knew I would only use the air purifier in my living room/kitchen space (it would be overkill in one of the bedrooms), I never bothered installing it.
There’s a leather handle on the back of the air purifier that makes it easy to move short distances. However, it weighs 28.7 lbs / 13kg, so if you need to move it frequently or transport more than a few feet, it would probably be a good idea to attach the wheel base.
Around the circumference of the Atem X, three-quarters of the grilles are for air inlet, and one quarter (at the top) is for air outlet. The direction of the airflow can be changed to flow towards the left or towards the right of the top of the purifier.
As well as being aesthetically pleasing, the air purifier is also quite functional and user-friendly. The recessed controls are on the back, directly underneath the outlet grille. I never encounter a problem trying to access them – and honestly, I think that placing them on the back contributes to the beauty of the air purifier and prevents it from looking utilitarian).
They include the power button, smart mode (to switch between the manual fan speed settings and automatic fan speed control), light button (to turn the control panel lighting on or off), Wi-Fi button, filter status, and Ethernet status. There are eight options on the fan speed slider, and this is also where the air quality index color is displayed (when not changing the fan speed).
The air quality indicator colors are as follows: green for good, yellow for moderate, orange for unhealthy or sensitive groups, red for unhealthy, purple for very unhealthy, and flashing purple for hazardous.
The IQAir Atem X can also be controlled via a companion app. Attached to the back of the stand is an ID card that contains the QR code to scan and download the app, the Certification of Performance, and the serial number. In addition, the company recommends using the card to pry off the air purifier’s front cover when it’s time to replace the filters (and I can confirm the card works much better than a butter knife or flat-head screwdriver, which could damage the panel).
The filtration system includes three ‘impactors’ – equivalent to pre-filters – which are designed to trap large particles, lint, and fibers. Underneath the impactors are the main filters, called HyperHEPA (editor’s note: I’m confirming with IQAir, but assume these are not true HEPA filters). These are designed to seize hair and dander, pollen, mud mites, airborne mildew, viruses and micro organism.
Rather surprisingly at this value level, there isn’t any activated charcoal filter. As a common rule, I’m inclined to dislike air purifiers that do not comprise activated charcoal, as a result of that tends to be the ‘secret sauce’ that removes the odors. For instance, my Alen BreathSmart 75i has a giant, heavy odor filter and I can really shake it and listen to the activated charcoal inside. However, this does not appear to influence the Atem X’s capability to clear odors, as I’ll get into within the Performance part.
Fortunately, this is not a kind of air purifiers that must be turned upside-down to take away the filters. However, the method is extra concerned than some opponents. After prying the quilt off, it’s worthwhile to unlock the locking levers and rotate the air air purifier to take away the grilles and the three filters.
The impactors are on the opposite facet of the grilles, and they need to be vacuumed with a brush attachment each time the air filters are modified. However, I vacuum each the air filters and impactors no less than month-to-month. Depending on how soiled the impactors get, they need to be rinsed underneath working water after which totally dried earlier than reinserting.

IQAir Atem X review: performance
- App provides a lot of helpful information
- 8 speeds and three special modes provide plenty of control
- Cleans air quickly and is quiet in use
As a general rule, I’m perfectly content to control the IQAir Atem X using the onboard controls – especially since I can easily reach it while sitting at my desk. However, for testing purposes, I downloaded the app to my smartphone and spent some time controlling it from there.
The app is chock-full of helpful information. For example, it shows both the daily and the hourly weather forecast in my area, as well as the humidity level. The app also provides health recommendations based on the local air quality, such as “enjoy outdoor activities”, and “open your windows to bring clean, fresh air indoors”.
With the air purifier, the app measures such pollutants as PM2.5 (fine particles), PM10 (larger particles), and carbon dioxide levels, as well as humidity levels, and the temperature in the room.
Inside the app, I can turn the air purifier on and off, and adjust the fan speed, brightness levels, lock the control panel, view remaining filter life, and use smart mode. There are actually three smart modes I can select from in the app – and they’re not available on the onboard controls.
Quiet mode ensures the fan speed does not exceed level 5. Balanced mode ensures the max fan speed does not go higher than level 7. During periods of high pollution, Max mode changes the fan speed accordingly, with no limit on fan speed. In Smart mode, the air purifier’s fan will automatically adjust based on pollutants detected.
I love having 8 fan speeds, so I can set the purifier precisely to fit my comfort level. I tend to use level 4 or 5, as this removes polluted air quite well, while still being relatively quiet. (For example, the noise level is around 44dB on the 4th speed, compared to 65dB when it’s set on 8).
There’s a reason why I can set it at a lower rate and still clean the air. That’s because the average air purifier that’s considered good (not to be confused with just the average air purifier) has a CADR in the 200 range. However, the IQAir Atem X has CADRs of 417 for dust, 422 for tobacco smoke, and 454 for pollen. This means that it cleans air at a much faster rate. (It’s more normal for a purifier to just have one CADR, which would usually either be an average of the rates for dust, tobacco smoke and pollen or the highest of those three.)
For example, when I walk into the living room and my neighbor has been smoking – I set the air purifier fan on 8, it removes the smoke and odors in less than 10 minutes (usually only 7 or 8 minutes). And then I set it back to 4 or 5 to maintain the clean air.

How I tested the IQAir Atem X
I used the IQ Air Atem X in my condo-style apartment (open living room/kitchen, 2 bedrooms, built in 2016, HVAC) for a year and a half. During this time, I used it primarily in the living room/kitchen area, to clear cooking smells and second-hand smoke from my neighbor. I don’t need that much power in my bedrooms – and I don’t want to push it from room to room.
For this review, I noted how it responds to various pollutants and how quickly it removes them. Since I work from home and sit at my desk at least 8 hours a day – usually more – and my desk is close to the kitchen, I’ve had plenty of opportunities to test it with various cooking odors, especially when I’m writing and not paying attention to what I’m cooking. As a consumer tech journalist, I’ve reviewed over 50 different air purifiers, and I drew upon my experience to get a feel for how the IQAir Atem X compares to the wider market and if it is a good value for the money.
