IQAir HealthPro Compact XE Air Purifier - 2-Pack - Compact HyperHEPA Fration for Rooms up to 2480 sq ft - Allergens, Smoke, Dust, Mold, Pet Dander, Swiss Made, WiFi Enabled

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.

There are two aspects to the "XE" purifier: 1) the actual mechanical unit and it's purifying abilities, and 2) the app control.1) The air purifying capabilities of this is incredible. We've used cheap air purifiers before and never noticed much improvement. That all changed when we got the HealthPro XE. The quality of the air in the house changed dramatically. Crystal clear. Within hours the "old house smell" was completely eliminated. Pet orders gone. And using an air quality meter confirms that the particles in the air across multiple sizes are pretty much completely eliminated. I was surprised at how quiet it is for it's effectiveness. At first I was skeptical that it would do much given the low velocity of the air coming out of it, but I was wrong. Absolutely incredible, and I am absolutely looking for an excuse to buy another one.2) The app control works fine, shows indoor vs outdoor air quality, let's you setup schedules or use the "balanced" mode which automatically detects air quality and adjusts fan speed accordingly. We found that balanced mode does not work for orders, though as these are no necessarily particles. With balanced mode, it will keep the fan fairly low and only occasionally increase the speed when we cook something, for example. But with the lower speed, odors are more noticable in the air, even though we've confirmed that the PM1, 2.5, and 10 are all at zero ppm. So, we tend to just keep it at a higher fan speed at all times to get the full effect of mountain fresh, crystal clear air.Ok, maybe I'm being a tad hyperbolic. The air coming from the purifier isn't quite the same as fresh mountain air. It does have a slight oder from the filters themselves. Hard to describe...kind of like a clinical smell you'd find in a hospital where these are used. But it's not offensive, and overall the air quality is noticably better / different than without using it.Only downside is that the app doesn't seem to connect to the device when not connected to the same WiFi network. E.g., I can't turn the purifier on/off when away from the house. It'd be great if we had remote control over the Internet instead of just the local network.I think every house and apartment should have one of these to improve air quality. Seriously, if you can afford it, don't look any further. You will not regret it.

This is the perfect purifier. You’ll notice a huge difference within 30 minutes. I had a sewage line burst in my basement near the multigas purifier and it managed to filter all of the VOCs in the area and kept my other room down there from getting fumes in it. I will say after the sewage burst and I carpet cleaned the hell out of everything. Steam cleaned used all kinds of cleaners and so on. It saturated the 12 pounds of carbon and I had to replace it 3 weeks after this incident. But unless you have extreme VOCs like that you won’t have to deal with what I dealt with
