IQAir HealthPro Plus XE Air Purifier - 3-Pack- Smart HyperHEPA Filtration for Large Rooms up to 3375 sq ft - Viruses, Allergens, Smoke, Mold, Dust, Pet Dander, Swiss Made, WiFi Enabled

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.

Pricey but well worth it high quality product definitely worth buying never thought air purifiers were worth anything ut was definitely wrong highly recommend

Came with purple ink marks on corners (see pictures). I wiped it off thinking it's just normal but asking LLMs it looks like this is not normal for a premium product. One edge had some scuffs that I could not wipe off. Using the unit I had mixed feelings. It solved my allergies but gave me a weird cough / throat dryness. I don't want to take chances so will ask them to replace.

2nd unit I ordered for bird room. 1st one lasted a long time

One of the best items I have ever purchased related to air purifiers.

Great air purifier, but the company practice is really scummy. The hardware supports air filter quality monitor of 2.5 and 10 sized particles, but they have it partially DISABLED (2.5 only) (this makes it hard to tell if it’s doing its job, as some particles are NOT that small so it seems like the air is good quality, even if there could be an air quality problem from larger particles). It still says on their page you can request the data (since it’s yours, you should be able to!) so you can view it or manually graph it, but they have since REMOVED that ability too. So the ability to capture and record the information is there, and its gathered and viewable to them, but not only do they not add it to the app, they actively REMOVED your ability to access the data in ANY form. Love the hardware, but cant give this a good review because of the absolutely scummy business practice. They have the functionality already made for their other devices, it would be as easy as enabling that functionality for this device, but they want to artificially gate it behind their other products, because $1200 isn't enough for them I guess.

Get the full size model - with three filters - the two filter compact model does not remove odors well.

After waiting several days, we received a machine that appears to have been previously used, despite the fact that it costs over $1,000. Additionally, we were informed that a direct replacement is not possible. This is very disappointing and not the level of product condition we expected.
