This is a wonderful air purifier. I've had it running constantly since I received it a couple of weeks ago. It started making a big difference in a couple of days. My allergy symptoms have virtually disappeared (indoors at least). It is obviously removing the pollen, dust and mold from the air in my home. I can see the difference with the dust, and I can feel the difference with the other allergens. The gas/odor filter also works very well. A neighbor's cooking smells are often unpleasant and strong -- this filter made them disappear. The unit is very quiet on the middle and lower speeds, and not bad on the higher speeds. This Swiss-made air purifier appears to be very well made. The materials and construction appear to be high quality. It is an expensive item, but if you live in a region where there is year round pollen, dust and mold, and you are allergic to it all, this is definitely worth the investment. But BEWARE: if you do not purchase this item directly from the manufacturer, or if you select a seller on the Amazon site that is not an authorized dealer, your unit will have no warranty at all. The seller I selected when I bought this unit on Amazon was an Authoruzed dealer, but somewhere along the way, my unit was sold by a different seller that was not even on the Amazon list of sellers. That dealer was not authorized by IQAir. I resolved the issue after speaking with an IQAir rep, who was very professional and attentive. She authorized their basic 1-year limited warranty, but could not offer me their free upgrade to a 10-year warranty. I accepted this offer so I have one year of coverage on this expensive machine, and I did not have to go through the hassle of returning the unit to Amazon, getting a refund, finding another (authorized) seller, and ordering another machine. This air purifier is absolutely worth the investment, but at that price, there should be a warranty. Avoid this problem by either buying direct from the manufacturer or making sure before you buy on Amazon that the seller you select is the one who is your actual seller, and that seller is an authorized dealer. I personally prefer to shop using Amazon Prime. I got my unit at the promised time, very well packaged, and in perfect condition. The seller, when I contacted them by email, was very helpful, but unfortunately was not an authorized dealer. They offered to provide a warranty themselves, but I wanted my warranty directly from the manufacturer. If you prefer, as I did, to buy on Amazon, I think you can go to the IQAir website to find out which Amazon sellers are authorized dealer. I have suggested to Amazon that they make sure someone doesn't switch sellers on you, and that they make it very clear that you are, or are not, buying from an authorized dealer, and the impact that can have on your warranty.

I absolutely love IQ Air. The quality is superior to that of any other air purifier I’ve ever owned. This is my second IQ Air. The best part is that the addition of great quality is their convenience app, which tells you the air quality both outside and inside your home. IQAir GV may seem significant as it’s about 3’ x 14”, the moment you plug it in, you know help is on the way for the quality of air in your place. After about an hour, a massive difference in the air quality is noticeable. Allow your app an hour to update the air quality in your home. With the automatic settings, the speed will adjust as needed, either lowering it when necessary or increasing it when required. It is super quiet. It makes sleeping very easy and much more comfortable knowing that the air is clean and being monitored. The ease of use was crucial when I decided to purchase another IQ Air; the app tells you which filter needs to be replaced. The good news is you have over a year for some of the filters before needing to replace them. The convenience, the quietness, and the fact that it keeps the room cleaner with less dust all enhance my sleep quality. I highly recommend this product for anyone with allergies who wants to improve their quality of life.

I got this because I live downtown in a 30 floor hi-rise with a common vent that spews not only all the heat in the winter and air conditioning throughout the summer but also the germs illnesses and everything else that anyone has living on any of the 29 floors below me. I also developed chronic sinusitis and I was sick all winter every winter. On top of that, being downtown, soot and all other kinds of emissions came through the leaky, rattling old windows that spanned from wall to wall and from ceiling almost down to the floor. Gorgeous view of the city but terrible on my health. I bought this and the reduction in dust in the apartment was amazing. I had sinus surgery that clean out a massive infection and I started getting well very fast. For the next 18 months I was sick only twice and got well without any antibiotics. about a year and a half ago, the landlord finally put in new windows that made everything air tight. I have no idea why but only this winter did my bedroom get so stuffy at night it would wake me up. So I started leaving a window open a bit and did so throughout the apartment. Thinking it was foolish to "clean the incoming air" with the IOAir -- I turned it off. Within 6 weeks I was sick twice (and i am now ), my room became incredibly dusty again and the smell in my room was never fresh. SO I just turned it back on at high speed. But before I did, I changed the pre-filter because it was time. I could not believe the soot and everything that came out of the old one. A young woman with me became instantly sick with sneezing. Well the filter has been changed, the machine has been on at high speed for several hours and the air smells fresh again. But I am now working in my study -- a room I have not been in for the longest time -- and the air does not feel great. So I am back -- to purchase a second unit for my study, a replacement filter and the PF40 kit IQAir Coarse Dust Pre-Filtration Kit ti add another layer of filtration to the bottom of my original unit. I will never, EVER, turn off this unit again. I plan to get one for every room in the apartment (i.e., two more -- one for the living room and one for the dining room.) It's expensive but I guess that really good product that really works is expensive....and worth it.

Very happy with this air purifier. Also got the AirVisual Pro monitor. Well packaged and received in pristine condition. Both integrated easily with my home WiFi. Most interested in PM2.5 and on initial start up it was at zero. Started cooking bacon in my convection oven and the reading spiked to 120 purple range. The purifier on auto picked up speed and cleansed the air in no time. Many cool features in the app. I'm very impressed with this tech.

Based in UAE, been using the Atem X air purifier for almost 2 months now and there is really a significant and noticeable improvement in the indoor air quality in our room. As someone who is very sensitive to dust, it helped with my frequent sneezing. I can spot less dust in my home furnitures. The design/controls are great specially the option for quiet function. It does not disturb our sleep but still effective & high power. I love that I can easily control it using my phone. Will definitely also have it for my living area.

Der beste Luftreiniger für mich. Bei meiner Gesundheit mache ich keine Kompromisse. Würde immer wieder auf IQAir gehen dafür.

It's easy to set up and the app is excellent. Works well, runs quietly and looks great. It's certainly a bonus that it can be placed against a wall. The base with casters snaps on if you want it to be mobile. It doesn't come cheap but the improved air quality, and the obviously excellent build quality of the device, are worth it.

The purifier looks good and comes ready to use out of the box. No need to install the filters like in other models. Pairing the unit with the phone app was easy, instructions were clear. The app is well designed and intuitive, easy to use, made configuring the unit a breeze. The unit has a quite mode of operation which is very useful if the unit is located near you or if the room is on the small side - this takes care of your ears by not raising the motor power too high! I took a star due to some features missing from the app: although the unit measures the content of PM2.5 and CO2 continously, it does not allow to program the unit to turn on if one of those parameters goes outside a threshold, and to turn it off when the air gets clean enough. This means you still need to use some external logic and devices if you care to have the air purifier turned on when the air gets dirty without having to keep the unit on at all times (just using up the filter for nothing). I am surprised this feature is missing, cheaper brands have been offering it for 5 years or more! Also, even if this model has a wired network option, the option is not shown either on Amazon or on the manufacturer's own website! This is important for people who don't have a wifi network or who don't want to keep one turned on everywhere. All in all, this a very new and welcome addition to IQair's air purifiers portfolio, pushing them forward in the modern world of intelligent devices (those using thier other air purifier products like the bigger HealthPro line understand what I mean).
