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.
Underneath its fashionable exterior, the IQAir Atem X works harder than the most utilitarian of air purifiers. This is one of the very best air purifiers I've used, and I've tested over 50. The only model that I've been more impressed by is the Levoit EverestAir, and it's a narrow margin.
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.
(Image credit: Future)IQAir Atem X review: price & availabilityThe IQAir Atem X is available to buy online in the US from the IQAir website or via Amazon. At list price it costs $1,3999. It's also available in various other countries, but typically via dealers.
The air purifier uses three HyperHEPA filters at a time, and the replacement pack is $199, which is among the most expensive filters I've ever encountered. Fortunately, the filter pack only needs to be replaced once a year if you're using the purifier regularly, or maybe less often if it's not being used as much.
In the air purifier market, the IQAir Atem X is considered a premium purchase. It's significantly more expensive than my favorite purifier, the Levoit EverestAir, which has a list price of $499.99 and is comparable in performance. Price-wise, the IQAir Atem X is comparable to the Dyson Purifier Big+Quiet Formaldehyde BP04, which retails for $1,199.99 at the time of publication.
The IQAir Atem X is an extremely good air purifier, and the various functions, user-friendly features, and quality build help justify the price. However, it is incredibly expensive – and especially if you factor in the ongoing cost of filters – and may not be in everyone's budget.

IQAir Atem X review: designThe 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.
(Image credit: Future)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.
(Image credit: Future)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).
(Image credit: Future)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 capture hair and dander, pollen, dust mites, airborne mold, viruses and bacteria.
(Image credit: Future)Rather surprisingly at this price point, there's no activated charcoal filter. As a general rule, I'm inclined to dislike air purifiers that don't contain activated charcoal, because that tends to be the 'secret sauce' that removes the odors. For example, my Alen BreathSmart 75i has a big, heavy odor filter and I can actually shake it and hear the activated charcoal inside. However, this doesn't seem to impact the Atem X's ability to clear odors, as I'll get into in the Performance section.
(Image credit: Future)Fortunately, this isn't one of those air purifiers that needs to be turned upside-down to remove the filters. However, the process is more involved than some competitors. After prying the cover off, you need to unlock the locking levers and rotate the air purifier to remove the grilles and the three filters.
The impactors are on the other side of the grilles, and they should be vacuumed with a brush attachment whenever the air filters are changed. However, I vacuum both the air filters and impactors at least monthly. Depending on how dirty the impactors get, they should be rinsed under running water and then thoroughly dried before reinserting.
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".
(Image credit: IQAir)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.
(Image credit: IQAir)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).
(Image credit: Future)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.

Buy it if...You like customization options
Most air purifiers give you 3 to 5 speeds, but the IQAir Atem X provides 8, and you can also adjust several other settings as well.
You want to clean a large space quickly
With some of the highest CADRs on the market, the IQAir Atem X is great for use in large spaces.
You want an air purifier that looks good
Some air purifiers look like something you'd find in a hospital, and although the IQAir Atem X is white, it does not have that sterile, clinical look. The Swiss-design is actually quite beautiful.
Don't buy it if...You want a quick and easy filter replacement process
It's not hard, but there are several steps involved in disassembling the IQAir Atem X, including prying the cover off, unlocking the locking levers, rotating the air purifier to remove the three filters, and pressing down to remove the impactors. Compare this to some air purifiers that only require pulling the magnetic cover forward, and then pulling out only one filter pack.
You're on a budget
You're getting into an arm-and-a-leg territory (possibly a kidney) to purchase the IQAir Atem X Air Purifier. There are certainly less expensive options on the market to choose from, and if you're only cleaning a small space, it's overkill.
You want to use voice assistants
Although there's an app, which is quite easy to use, if you want to be totally hands-free, you may prefer an air purifier that is compatible with Alexa or Google Assistant.
How I tested the IQAir Atem XI 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.

The Acer Aspire Go 15 is an affordable Windows laptop with a spec that should prove capable enough for everyday use.
Considering its 15.6-inch form, it has a sleek and slender body. It’s also quite thin and light, which makes it easier to carry around than expected. The light silver finish and minimal aesthetic also imbue the Aspire Go 15 with some style, although there are a few unsightly angles that mar its appearance somewhat.
It isn’t built to the same high standards as the best laptops, much less many of the best Ultrabooks, either. The materials aren’t premium, and its construction isn’t as reassuringly solid as I would’ve liked. The lid isn’t the most stable, either, and its downward protrusion means it lifts up the rear of the unit when opened beyond 90 degrees, which is a design choice I’m not particularly fond of due to its impractical nature.
On a more positive note, there’s a decent selection of ports, including three for USB-A, one for HDMI cables, and one for Ethernet connections. There’s only one USB-C port, though, and no SD card reader.
(Image credit: Future)The everyday performance of the Aspire Go 15 is very good, handling light productivity and entertainment workloads with speed. However, more intensive tasks such as gaming fare worse, given that it lacks a dedicated GPU. Light gaming is still possible, though, and both fan noise and temperatures are kept to a minimum.
One of the most disappointing aspects of the Aspire Go 15 is its display. Its grainy finish can be distracting, while colors can look a little washed out in some cases. Worse still is the restrictive viewing angle, with images and scenes becoming totally obscured when the display is set even slightly beyond optimal bounds.
The battery life of the Aspire Go 15 is quite good, though, lasting close to 12 hours during our movie playback test. However, there are quite a few rivals that can outlast it, such as the Dell 14 Plus.
Considering its price, the Aspire Go 15 represents a very good value, offering a more affordable alternative to the best Windows laptops that cost a good bit more. There are also better-performing Chromebooks for less money, such as the HP Chromebook Plus 15.6-inch, which also has a better display, but if you can live with its display, the Aspire Go 15 is one of the best budget laptops going and well worth adding to your shortlist.
Acer Aspire Go 15 review: Price & AvailabilityThe Aspire Go 15 starts from $299.99 / £299.99 (about AU$450) and is available now. A range of Intel and AMD CPUs are available to choose from, while RAM and storage capacities range from 8GB to 32GB and 128GB to 1TB, respectively.
This is a good starting price for a Windows laptop, but for this outlay, you’ll have to settle for a weak spec. My review model was considerably more powerful than the base model, and priced closer to some strong rivals.
However, it still undercuts other affordable Windows machines, such as the Dell 14 Plus. We found this laptop to be an excellent value, though, thanks to its fast performance and enduring battery life, while its light design even makes it a worthy alternative to some of the best MacBooks.
If you’re willing to look beyond Windows machines, the HP Chromebook Plus 15.6-inch is another enticing proposition. This is cheaper than the Aspire Go 15, but has a stronger performance and a superior display that doesn’t suffer from the same issues. No wonder we think it’s one of the best Chromebooks around right now.

A wide selection of spec configurations are available, with both Intel and AMD processors. There is a mix of PCIe 3.0 and 4.0 SSDs depending on the spec, so some drives will run slower than others, and that's not always immediately apparent when looking at retailer specs sheets.
It also doesn't include the latest Wi-Fi and Bluetooth standard, but Wi-Fi 6 is fast enough for most people's needs, while the inclusion of an Ethernet port is welcome.
Overall, for their various price points, these are about the specs one should expect.
The Aspire Go 15 is a basic but smart looking laptop, with extraneous details kept to a minimum. The light silver finish of my review unit helped to impart some elegance, too, although a few unsightly juts and angles spoil its otherwise smooth contours. While the Aspire Go 15 is quite wide, it’s relatively light and pleasingly thin, which makes it easier to carry around than you might imagine for a 15.6-inch laptop.
Build quality isn’t exactly the greatest, though, with cheap looking – and feeling – plastics that flex to an inauspicious degree. Thankfully, the keys feel more premium: they’re solidly fitted and have a prominent texture that’s satisfying to touch.
(Image credit: Future)The lid is also better made than the rest of the unit, featuring a solid yet smooth hinge mechanism. I welcomed how thin it was, too, although I was less keen on its bottom protrusion. This causes the rear of the Aspire Go 15 to lift off ground when opened to angles beyond 90 degrees – a deliberate design choice but one that feels unintuitive and can result in loose fabrics and other materials underneath the chassis getting caught, which isn’t ideal.
There was a reasonable selection of ports on my Aspire Go 15 review unit. I welcomed the three USB-A ports, spread across both sides for added convenience. There was also an HDMI port and an ethernet port: increasingly rare sights on modern laptops, and again ones I was glad to see. There’s only one USB-C port, though, and no SD card reader, both of which are mild shames.

For everyday tasks, the Aspire Go 15 is very capable. It can handle light productivity, from word processing to spreadsheet creation, without much if any slowdowns. It also had no problem streaming 4K content. I didn’t experience any midway buffering pauses or stuttering, for example.
However, the viewing experience is marred by the quality of the display. It has a noticeably grainy finish, which can be distracting at times. Colors can also look washed out.
What’s more, the display darkens considerably if the angle isn’t set just right, to the point of near-total blackness sometimes. Thankfully, once you’ve found the optimum position, there are next to no reflections visible on screen.
Since there’s no dedicated GPU installed in the Aspire Go 15, it isn’t particularly great for creative and gaming workloads. Cyberpunk 2077 is playable on the lowest preset, but naturally, you’ll have to make do with some rough visuals and uninspiring frame rates.
(Image credit: Future)The game is even passable on Medium settings and upscaling, but you’ll have to contend with even lower frame rates and more input lag, rendering the experience less than enjoyable.
Mercifully, though, I experienced little fan noise from the Aspire Go 15 during such intensive workloads, never elevating above a faint whir. It also stayed commendably cool, with certain portions of the body reaching lukewarm temperatures only.
Another highlight of the Aspire Go 15 is its keyboard. The aforementioned keycap texture helps them feel more tactile, as does the surprising amount of dampening of the switches, despite their short travel and very low profile.
What’s more, they’re snappy and responsive, which only improves their typing prowess. And despite featuring a number pad, the layout doesn’t feel cramped. Those number pad keys are relatively small, though, but they’re still eminently usable. So overall, if you’re looking for one of the best laptops for writing, the Aspire Go 15 could well be a contender for you.
The touchpad is less pleasant to use, though. While it’s smooth enough for easy gestures and swiping, it’s not as large as those in other 15-inch laptops, which compromises its navigation abilities. Also, clicks and taps lack feedback and even rattle at points, which further hampers their functionality.
The battery life of the is quite impressive. It managed to last close to 12 hours when playing a movie on a continuous loop. It’s also quick to charge, taking about two hours to fully top up.
The HP Chromebook Plus 15.6-inch achieved a similar score. However, others in this sector can outlast it by quite some distance, including the Dell 14 Plus, which lasted over 13 hours when we ran a similar test.

How I tested the Acer Aspire Go 15I tested the Acer Aspire Go 15 for several days, using it for working, entertainment, gaming, and general browsing.
I also connected various peripherals to it, and ran our series of benchmark tests to assess its overall performance. I also tested its battery life by playing a movie on a continuous loop until it expired.
I have plenty of experience testing all kinds of laptops, from everyday workhorses to high-end specialist machines. I’ve also reviewed Chromebooks and other computing devices, such as tablets.
