IQAir Atem Earth Air Purifier Review


Verdict

Air purifiers are designed to improve your indoor air quality, but almost all of them contain plastic components that are not good for the environment. However, the IQAir Atem Earth is one of the first known air purifiers that’s housed entirely in sustainably forested beech wood, with a natural finish. And true to the Swiss aesthetic, it also has a beautiful, minimalist design. In addition, the air purifier has an ENERGY-STAR certification for energy efficiency. Plus, the higher-than-average CADRs (clean air delivery rates) allow it to remove polluted air much faster than most air purifiers.

  • Beautiful design

  • Made with sustainably-sourced beech wood

  • Better than average CADRs

Introduction

The IQAir Atem Earth is one of the first air purifiers to be housed entirely in sustainably-forested beech wood with a natural finish (free from paint or varnishes, which tend to be harmful pollutants). It’s something we tend not to think about, but if you do stop and think, the appliance you’re using to remove pollutants from the air could actually be contaminating your air as well. The Atem Earth avoids this – but at a steep cost.


Design and features

  • ENERGY STAR certified for efficiency
  • Both manual and app control 
  • 6 fan speeds

The IQAir Atem Earth arrived in a large branded carboard box. It had taken some knocks from being tossed and thrown around during the shipping process, but fortunately, the air purifier was securely packed to prevent damage. 

The Atem Earth is simply beautiful – no surprise, since it’s Swiss-made, and they take their design aesthetics quite seriously. The housing is a conical shape in beech wood with a natural finish

The vegan leather strap on the top makes it easy and combined with the handle (a vegan leather strap), the air purifier is modern, stylish, and sustainable.

Besides plastic parts, energy efficiency is another issue with air purifiers, which can require a considerable amount of electricity to operate. However, the Atem Earth is ENERGY STAR-certified, and annual energy use is 295 kWh/year in a 572 sq. ft. room. If you’re not familiar with the ENERGY STAR, it’s a symbol of the U.S. Environmental Protection Agency indicating that an item is designed to provide cost-saving energy efficiency.

On the top of the air purifier is the air outlet and the control panel. Air comes in through the main body, which sits on the base. 

The touchscreen control panel includes several icons: 

The power button/indicator turns the power on, and puts the air purifier in standby mode

Fan speed indicators reveal the current speed

Fan speed buttons are plus and minus signs used to increase and decrease speed; there are 6 total speeds

The smart mode/indicator, when activated, automatically adjusts the fan speed based on current air quality

The Wi-Fi button/indicator is used to connect the air purifier to a Wi-Fi network

The light button/indicator turns on/off the lighting on the control panel 

The air quality indicator rings are in the middle of the control panel; they can compare air quality on the inside of the home (inner ring) with the air outside (outer ring)

The schedule indicator lights up when an air purifier schedule has been set on the app

The lock indicator lights up when the control panel has been activated on the app

The Atem Earth’s replacement filter is $100, which is expensive; however, with normal use, it should only need to be replaced every 12 months.

To change the filter, the air purifier needs to be turned upside down and then change the direction of the locking levels to open them.

Then the bottom lid can be taken off, revealing the filter.

The combination filtration system consists of the HyperHEPA filter on the outside, and the activated carbon on the inside.

On the side of the air purifier is a tag containing the Atem Earth’s QR code. Scanning this allows me to begin the Wi-Fi connection process, and then connect to the IQAir AirVisual app, so I can control the air purifier remotely. Usually, controlling an air purifier by app provides convenience. However, with the Atem Earth, it is essential, since there are some functions that can only be activated and controlled through the app.

For example, only in the app can I set up an outdoor air comparison, access smart mode, set a schedule, lock the control panel, and get detailed info about remaining filter life.

Performance

  • CADRs are excellent across the board
  • HEPA and activated carbon
  • 3 smart modes

The IQAir Atem Earth’s CADRs are as follows:

  • PM2.5: 376
  • Smoke: 369
  • Dust: 382
  • Pollen: 423

These clean air delivery rates are much higher than those found in the average “good” air purifier, which is usually in the high 100s to mid 200s. As a general rule, the higher the CADR, the faster the air purifier can clean the air.

These high CADRs are a result of the air purifier’s filtration system. The medical-grade HyperHEPA filter can capture ultra-fine particles – and the company states that it can also trap biological contaminants and viruses (although I can’t prove that, so I don’t list it as a feature). On the inside of the HyperHEPA filter is the activated carbon, which controls gases and odors. I can indeed confirm that the air purifier does a marvellous job of removing large and small pollutants and odours.

I have a smoking neighbor, and when the Atem Earth is set on 6 – the highest fan speed – it quickly removes polluted air from whatever room I’m in.  However, when she’s not smoking, the air purifier is usually set on 3.

The reason I don’t just leave it in smart mode is that I’ve noticed (like most air purifiers) the Atem Earth doesn’t automatically pick up smoke and fumes coming from a distant source. That’s why I don’t test air purifiers by burning a match or lighting something right next to it. All air purifiers worth their salt can detect a match that’s 12 inches away, and detect the smell of burnt food coming from the kitchen.

However, when I smell tobacco smoke from my neighbor, my eyes start either burning or itching (depending on what she’s smoking), I’m coughing, my nose is either stopped up or running, and the air quality indicators on the vast majority of the over 50 air purifiers that I’ve tested (including the Atem Earth) will still show that the air is in the good range. That’s why I don’t trust the smart/automatic settings. However, by keeping the fan speed on a level 3 or 4, if said neighbor starts smoking when I’m in another room, that smoke isn’t building up in my absence.

Even though I don’t use automatic modes, I should note that there are three smart modes on the Atem Earth: quiet mode limits the maximum fan speed to 4; balanced mode limits the max fan speed to level 5; and max mode has no limit on the maximum fan speed when it detects a high level of air pollution in the room. 

Should you buy it?

You want to reduce your environment impact

According to IQAir, the Atem Earth Air Purifier has five times less plastic than conventional purifiers. Also, it has a 25-year repairability guarantee, which is unheard of, so you won’t be throwing this away any time soon.

You want something cheaper

This air purifier is very expensive and you can get similar purification results with cheaper products.

Final Thoughts

The Atem Earth is a great choice for so many reasons. It’s a sustainable air purifier that still manages to be modern and stylish, and it’s also an energy-efficient choice. The medical-grade HyperHEPA filter, combined with activated carbon, quickly removes polluted air. 

At just under $1,000, the Atom Earth is not for everyone, and probably not for most people. Although it’s energy efficient, I doubt that you’ll recoup your investment in electricity savings. However, if money is no object- or you do have a grand budgeted for an air purifier – it’s an excellent choice to thoroughly purify your home.

If Game Two of their first-round playoff series with the Denver Nuggets saved the 2025-26 season for the Minnesota Timberwolves, Game Three showed why it should be saved. 

The Timberwolves were a different beast while decisively thumping the Nuggets, 113-96 Thursday night at Target Center, in a game that wasn’t nearly that close. These Wolves were the mythical creature we’d heard about in preseason lore, purposefully locked and loaded to be both marauding and staunch. They owned both ends of the court, gleefully transferring back and forth from irresistible force to immovable object. 

A quartet of Timberwolves deserve special mention, but it begins with Jaden McDaniels. After his team had toppled Denver to even the series at a game apiece Monday night, McDaniels used the sizable chip on his shoulder to etch some graffiti into the public discourse, casually castigating the most prominent Nuggets players by name as “bad defenders” in a matter-of-fact manner that had the media compelling him to confirm what he had just said. 

Trash talk is fleetingly fungible in the jaundiced social environment of 2026, functioning more like coupons than currency in that it needs to be rapidly leveraged before its expiration date. The common perception naturally was that McDaniels was calling out the Nuggets. But in a more subtle, profound way, he was also putting his teammates on notice. 

All season long the Timberwolves have procrastinated on their full potential, frequently demonstrating that their preseason talk about maturity and commitment was cheap. By contrast, those words uttered by McDaniels were expensive. He had just picked a fight with the opponent, leaving open the question of how many of his teammates would join him in the fray. 

That he would lead the charge was established early, after the Timberwolves’ top two scorers, Anthony Edwards and Julius Randle, had each missed a pair of open looks against Denver’s bad defenders in the game’s first 90 seconds.  

With the game still scoreless, the NBA’s best pick-and-roll combo, Nikola Jokic and Jamal Murray, were clustered around the foul line with Minnesota’s best defenders, McDaniels and Rudy Gobert. As they jammed up Jokic, McDaniels picked the ball loose and started sprint-dribbling the other way. To no one’s surprise, Donte “Ragu” DiVincenzo was also on his horse in transition, receiving a pass from McDaniels and then lobbing it back for a Jaden slam against a hapless Murray and Murray’s late-arriving teammate, Cam Johnson, who committed the foul that allowed McDaniels to finish with the “and-1” free throw. 

On the Timberwolves next offensive possession, McDaniels muscled his way to two offensive rebounds, feeding Ragu off the first one for a missed three-pointer, which he corralled for the second one and executed the putback in traffic. It was McDaniels 5, Nuggets 0, setting the tone for a game in which not only did the Wolves never trail, but never let the lead go under double digits after McDaniels made a consecutive pair of driving layups eight minutes into the game. 

“Spectacular. I thought his activity offensively in the first quarter was outstanding,” said Wolves coach Chris Finch after the game. “He was inspirational.” 

Among the most inspired were McDaniels fellow wing players, Ragu and Ayo Dosunmu. Ragu is exactly the kind of player who will have your back in a squabble, and his galvanized performance seemed borne of satisfaction that someone else had clarified the mission. As usual, the Timberwolves were at their best with him on the court: +20 in the 32:54 he played, -3 in the 15:06 he sat. 

“He makes so many hustle plays, momentum plays, different styles of plays.” Finch raved. “He’ll make a shot, get a transition bucket, he’ll rebound, get a steal, blow something up. So many different plays. He’s just a basketball player.”

Then there was Ayo, whose fearless, blazing, bee-lines for the bucket were quicksilver kryptonite for a Nuggets defense that is neither swift nor rugged. “I’ve been waiting for him to wake up a little bit in this series,” Finch accurately observed. “The downhill mindset that he played with all season for us was back.”

Back with the sort of multipurpose propulsion that leaves witnesses with giddy whiplash. Ayo led the team with 25 points and 9 assists in 32 minutes of time-lapse hoops, the lone blemish being three clanks from long range. Why chuck treys when you can so easily undress players in the paint? Ayo was 10-for-12 on two-pointers and none of those dozen shots came from anywhere but beneath the rim. Five of his nine dimes likewise yielded layups or dunks, which means he personally accounted for 30 of the 68 points in the paint by the Timberwolves on Thursday, doubling up the Nuggets’ 34.

Which brings us to the non-wing in Game 3’s ring of honor, Rudy Gobert. For the third straight game, Gobert blunted the supposed advantage Denver had with the magical playmaker Nikola Jokic at the controls. Suffice to say that in the last five quarters, Jokic has shot 8-for-33 from the floor. If that continues, the Nuggets are toast in this series. 

When I asked Finch after the game if the herculean job Gobert was doing on Jokic made planning his defense simpler and better thus far, he replied, “Rudy is making all of us look good right now with his defense.” 

Amen.

If there is an asterisk on this game, it would be the absence of Denver’s brutishly versatile power forward Aaron Gordon. Nuggets coach David Adelman should be given a lot of credit for his honesty and transparency in dealing with the media during his first full season at the helm, but it came back to bite him and his team during the pregame presser, when he was clearly rattled and dejected by the sudden unavailability of Gordon, whose playing status went to “probable” to “out” in a period of a few hours due to a chronic calf strain. 

Gordon is far and away his team’s best defender, making the timing of his injury especially troublesome in the wake of McDaniels laying down his marker. Rattled is a good way to describe the entire team’s performance in the first quarter, an emotional wounding that needs to heal as fast as Gordon’s body if the Nuggets are going to be competitive in a series that had dramatically been flipped on its head over the past three days. 

That the Timberwolves played with such dominance despite mediocre outings from Ant and Randle would be a good thing for both of those current cornerstones to keep in mind. Ant was beset by foul trouble and Randle had a solid second quarter, but it stood out that neither player fully embraced what so often works on offense when the Wolves are at their best: Push the pace, move the ball, move without the ball, and make quick decisions. Ant and Randle can still be first among equals and blend into that catechism if they stay attuned to the possibilities of a greater good, one that all of sudden doesn’t have to end with them being postseason fodder for the Spurs or the Thunder. 

Not when you’ve got three wings at a collective peak, with a chaser of Rudy semi-clowning the Joker.
