GC MultiGas XE

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 recently purchased the Atem X as I was concerned about the air quality, seeing as I live in the city. Although it was a little pricey, the quality and functionality make this purchase worth it!1) Monitoring your Indoor Air Quality Remotely is HUGEThe Atem X comes standard with an air quality sensor that monitors your AQI ( Air Quality Index), PM2.5 concentration, and CO2 concentration as well as the Temperature and humidity. You can view these readings remotely on IQAir's Air Visual App so when you're not at home and concerned about your indoor air quality, you can remotely control the Atem X to start purifying your air manually.Story Time: I was out and about the weekend after I had purchased my Atem X and noticed that my indoor air quality was at a whopping 150 the outdoor air quality is in the 60-80 range. I knew there was something wrong because the Air Visual App shows me the indoor and outdoor AQI in a side-by-side comparison. Long story short, my bad indoor AQI was a combination of my sister burning something in the kitchen, and my Central AC for the house being clogged up from a bad filter. Without this Atem X, I wouldn't have been able to act on the bad indoor AQI. With the touch of a button, I turned my Atem X on MAX and it cleaned the air quality right away!2) Smart Mode is a game-changer!The Atem X has a smart mode that can adjust its fan speed based on your Air Quality. Smart mode has 3 different levels, Quiet, Balanced, and Max. I usually keep it on Max as it allows the unit to use all of the available fan speeds to clean your air as needed, which I recommend.3) No oscillating fan feature, but Atem X's fan is better!I was kind of disappointed that this air purifier/ fan combo did not include an oscillating fan feature. However, once you start using the Atem X you realize that the way this system fans your area is superior to a regular oscillating fan. The Atem X blows air throughout your entire room/ space by increasing circulation with IQAir's flexible air rotation technology. Long story short it blows the air at an angle and the higher the fan speed, the more you feel it throughout the entire room vs. having to wait for the oscillating fan to hit you!
