Atem Desk Air Purifier for Home, Office, Desktop, Small Room up to 150 sq ft, HyperHEPA Filter for Bacteria, Viruses, Allergens, Pets, Asthma, Pollen, Dust, Swiss Design, Made in Germany, Black

I own two IQAir Health Mate Pros, which are the most effective air cleaners available, but a little bulky for trying to take on an airplane. When this came out, I had to give it a try. Happy to say that I've traveled with it three times, just packed in a bag, and it has given me blissful sleep on the pillows, sheets, and mattresses where I was staying. You need to set this up close to your head. It's not meant to clean the room, but to produce a zone of clean air around your head. On the highest of the three settings, it's audible, but that's about all. On the two lower settings the sound is barely noticeable. The quirks: (it wouldn't be IQAir without quirks) First, you plug the cord into the side of the unit and into the wall. You may need an extension cord in some hotel rooms, to run the power from the outlet to your face. The cord is reasonably long, but for some hotel rooms may just not be long enough. So bring an extension cord. The stand is actually cool. But, when you attach the disc-shaped unit to the stand, it doesn't really CLICK into place. Rather, it SLIPS into place. Result: If you try to pick up and move the unit, the stand may fall off. It'd be nice if it had some kind of positive attachment to the lozenge. I have no idea, obviously, how long the filter will last. I do know that I'm really glad to have this, and believe it will open up a world of travel that I thought I had lost. Edit: After a few months of ownership, I decided to try using this in my bedroom, every night, to help me sleep. The good news is that it works as well at home as it did in a hotel room. The bad news is that the filters don't last long at all. I run it on the highest speed, 3, for about 8 hours each night, and after about a month I'm starting to clog up and wake up coughing. Nor is it a slow decline. Rather, one night I'm fine, one night I struggle, and then it's hopeless. Too bad. But if you look at the filters you can see that they are rather small, without much surface area, and so it's no surprise that they fill up quickly. Once again, others whose allergies are somewhat less savage than mine may get more out of each filter. But this will be my travel filter rather than every day. I will not reduce the rating, because this was an unknown rather than an expectation, and this will still be the ultimate travel air purifier. But if you use it for travel, you may want to track the number of hours use, and when you get near to 250, swap it out if you're about to go on the road. Edit #2: The really interestingly-shaped filter sits inside this thing wrapped around the top and the back side, which I realized might cause problems with filter longevity. Why? Because dust can settle out of the air directly onto the filter, by traveling down. Unlike the big tall house-sized units that I also reviewed. So I started putting a plastic bag over the unit when not in use. Good news! Doing this about doubles the filter life for me. Going from one month to two months per filter is definitely worth it, given that all I do is put a trash bag over the thing. It still costs me about a dollar a night, but my sleep is so much better that it's worth it. Edit #3: After about a year of use I noticed that filter life was starting to tank. When you change a filter, you'll notice a second, smaller lift-off cover that has a little curved piece of styrofoam under it. This is the muffler, to reduce the already miniscule amount of sound the unit produces. Trying to clean this made it worse, but removing it entirely resolved the problem, and the unit is barely louder. So you may want to consider ditching this. It doesn't seem to be a replacement part, but I plan to go to the hardware store, buy matching foam, and cut out a replacement. I'll let you know.

This is an excellent air purifier! I have used it 24 hours a day for over 30 days. It maintains the PM 2.5 level in my 20 sq ft bedroom at 0 - 1 particle effortlessly on the lowest setting and is very quiet. While using air-conditioning or heating, it maintains sweet and fresh air. Amazing difference in air quality. Great product.

We bought this product after much research hoping to have a unit which would clear a small area of VOC (dryer sheets, fabric softener, perfumes, deoderants, etc...). We know the filter shipped with the Atem was not designed to help with VOC so be also bought the replacement activated charcoal filter which should help with VOC. What a huge dissapointment when we turned it on and "Morning Mist" (name your poison) wafted from the machine. Maybe they dip it in something to cover the smell of the plastic or circuitry or maybe the filter has a scent impregnated in it to give the impression of "fresh air" but if you are trying to avoid or rid your personal space of chemical smells, this will not do it but actually make it worse. We are willing to spend just about anything to help with this problem and the Atem is about 10x more expensive than all other personal air purifiers. It probably does a good job of filtering the air from dust and pollen but it does emit a smell (think truck stop urinal cakes) that obviously nobody on the design team had an issuse with. We had high hopes. It is nicely designed and small enought to travel with but the toxic smell is a deal breaker and headache maker.

I own two of the Atem desk and have the car version as well. I decided to get two desk models since I work from home and needed something in my office to help reduce pollen counts further (I have a few floor models filtering most of the house). But I also got one so that I can get a decent night sleep during allergy seasons. There isn't much to these devices, they push air through a hepa filter and it has smarts to link up to your cell phone. They have a feature that can use your phone's proximity to turn the unit on and off but unfortunately it's based on Bluetooth connectivity so unless you have EMI shielding in your walls that proximity sensing will not work well. What I mean is if you want the filter to turn on when you enter and off when you leave the room that doesn't work since these things will pick up a Bluetooth signal anywhere inside a normal size house. I'm sure they could improve it based on signal strength but the application doesn't have settings like those. If you are familiar with the floor filter models also keep in mind the hepa filter doesn't last anywhere near as long in this unit (nor should you expect it to). Luckily the hepa filters are cheaper for this unit so it probably evens out in the long run.

I brought this air purifier for my sons room as he had bad allergy. I wasn't sure if it would be enough for the room, but we have it for a week now and it's working great. The size is perfect for the room not too big or too small. I love the modern design with the hand touch on & off on the side. It was easy to setup - my 10 years old son put it together. We have it sit on top of their book case between the beds and so far I haven't see any dust in the room - with 2 boys in the room it usually get dusty even a day after we clean. Best part, my sons have stop coughing - no allergy - YES! The price is not cheap but definitely worth the money - I going to have to save up to get one for my room next.

Definitely works far better than any other purifiers, but the problems and quirks mean I'll be returning: A persistent rattle noise has emerged; the temperature gauge is usually off by +3-5 F; open the iOS app and the fan speed reduces slightly then returns to normal once I exit the app, rendering any changes to fan speed not quite right; can't figure out how to update firmware in the app; opened the unit per instructions from customer support but then refuses to click back together as it did when first assembled; customer support was responsive but disorganized (received two simultaneous but different email responses from two different support reps, then my case was quickly closed at 24 hours after I hadn't yet replied). Again, I would be keeping this for the filtration and superb design and compactness, but 99% of my Chinese-made devices have fewer problems than this German-made machine. Go figure.

We purchased this system because we wanted a smaller air purifying unit for our bedroom and as a portable device for travel. So far, we haven’t had the opportunity to take it on a trip yet, but we have noticed a significant increase in air quality since we’ve started using it. I routinely struggle with allergies this time of year and the iqair Atem has really helped with that. Its really easy to use - just tap the side to turn it on and off. But the most notable feature for me is how quiet it is - you hardly notice that it’s there. I’ve really been enjoying my purchase and would wholeheartedly recommend it if you’re looking for a smaller high quality air purifying system.

My apartment has carpet and my allergies always act up. I am very sensitive to dust! I have bought a few air purifiers before but they have always been so loud and never really worked. This air purifier is everything that I wanted! The fan noise is barely noticeable. It has a bluetooth function and an app (you can turn off the blue light in the app if you are sensitive to light when you're sleeping). Setting up the machine was really easy. It took less than 3 minutes to set it up. Turning on the machine just takes a tap on the side and you can also tap the side to change the fan speed. It also came with a bunch of power outlets so you can use it anywhere in the world. The vertical stand is great because it can fit on my computer desk without taking much space. I will probably buy the bigger one for my living room next. Overall I am very satisfied with this air purifier and would recommend it to anyone that has allergies!
