IQAir GC MultiGas XE Air Purifier - 3-Pack – Smart MultiGas Filtration for Spaces up to 3375 sq ft - Chemicals, Odors, VOCs, and Particles, Swiss Made, WiFi Enabled

I had an issue with a stranger smell in my bedroom that I did not know how to deal with, so much so I was considering breaking my lease and changing apartments. Instead, I bought this to clean the air and it solved my problem entirely. Also great getting the peace of mind with the air quality readings. Strongly recommend!

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.

The media could not be loaded. I got this multicast air purifier because I have chemical sensitivity and it’s severe and when something gets in the air and bothers me it makes me sick and stays in the air for a long time. So I got this to help clear the air faster and keep the air fresh and clean for me. I also have bad allergies and allergic things so this so far is helping me a lot I think it smells fresh and clean. Although I’m still trying to get past the new chemicals of the machine it self but I put it in a far room for now so it can clean its own smalls out of the air before it gets to me and it’s been ok so far.I love the app and how it revels up at even lower levels and says it unhealthy for sensitive groups at that point makes me feel like someone gets me. I can control from the app and turn it on a manual fan setting or balanced where it runs on low until something gets in the air and it ramps up. I love that it can tell at the low levels even that it needs to clean the air more so the fan goes on full blast. This is a great machineThis video is when it detects something and turned up all the way to high levels this is standing right at it so the sound being right at it sounds like this.

I've been working with a professional air quality tester who is helping me track down what is causing my serious allergies in my house. He recommended that I purchase an IQAir HealthPro Plus unit to help give me some relief from my allergies as we work to determine their source.After receiving the unit, I followed the instructions and got the unit running. I left it running for over 5 hours and planned on running it much longer, however my allergies increase greatly. I could tell the unit was just stirring up the air.The next day the professional air quality tester got out his commercial grade Particulate Matter (PM) reader. This thing costs $5500 and $500/year to calibrate. It uses laser sensors to read the particulate matter counts at a large range of sizes.We ran a series of tests: 1 at the input of the HealthPro and 6 more around the top of the unit where it outputs the filtered air. We did this at the highest fan speed. This is the same testing IQAir claims they do in their documentation when you receive your unit.We saw only a consistent ~40% reduction in PM. This is nothing close to the 99% reduction that IQAir rated my specific unit as being able to achieve. So, the reality is that the unit is stirring up 60% of the allergens and blowing them around the room.I scheduled a "virtual appointment" with IQAir to discuss the problem. The IQAir representative did not show up for the meeting after waiting for about 10 minutes. I reach her instead on the online chat on IQAir's website. She said we was stuck on a call. She never attempted to reach out to me. I decided to call IQAir's support.Support proceeded to tell me I wasn't using the unit correctly. They said I needed to *open the windows* on my house for the unit to filter properly. Seriously? Open the windows? I informed them that it is 20 degrees outside (and I’m not sure how this filter could work to filter out wildfire smoke if the windows have to be open). I asked why the unit would require the windows to be open. Support wasn't too clear on this point but it sounded as if they were saying the unit cannot keep up with the possible influx of new allergens and i need fresh air coming into the house to help reduce the allergens. This makes no sense to me. Either the filters work at 97-99% or they don't. I was taking all the PM measurements right at the input and output of the unit, not just any place in the room.Nowhere in the IQAir literature do they mention this sort of limitation or best practice of needing to "open the windows."The call ended with support.Later, IQAir’s representative who missed the virtual meeting then called me and sent me back to support, I mean why not, I love punishment. I next spoke with a second person at support and told them the problem again. This time they gave me a whole new story. They ask how big the room was that I tested the unit in and I told them 12x12. Support said I had the unit on too high for the room size and that this would cause the unit to be unable to filter the air passing through the unit properly. I have no idea how the room size could impact the filters since the amount of air passing through the unit would be the same regardless of the room size; it all has to do with how much air the unit’s fan is pushing through the unit, not the size of the room. I asked support if they could explain the relationship of room size to airflow but they couldn’t. I asked them what room size they use in testing, but they didn’t know.So, now I had two completely different answers from support that both make no scientific sense. However, both answers blamed me for the problem by implying that I didn’t use the unit properly. I will again note that nowhere in manual does IQAir tell you that room size can be too small nor that you need to open the windows. Somehow users are supposed to know these obviously important things; but honestly I think these items would make it difficult for anyone to take IQAir seriously and they refuse to print them.In the end, IQAir did offer a full refund and return, which I will be taking advantage of; though the first support representative didn’t even offer this. Only the second one.This leaves anyone considering buying this unit a huge question as to how IQAir makes their claims of any level of filtration. Open windows and only in large enough rooms appear to be factors that must be considered…if you don’t believe in science!
