GC MultiGas XE

I noticed an immediate difference in the Air. It smelled cleaner if that is a thing to say. I bought this as an upgrade from my current air filtration unit in my bedroom that just didn't feel like it was doing much. I have a couple indoor cats and felt my units were not keeping up with all of us being in the bedroom and sleeping. I now come home from work and the walking in the house, it feels and smells clean and fresh. I am sleeping much better at night now. It does have a noise factor but compared to my older other brand units, it is really quiet and they also have a turn the light panel off feature. I love the phone app and tracking the filters status and how it is working. The initial investment is expensive but the ongoing filters seems really reasonable compared against other brands.

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.

This air filter is indelible! It removed thar damp musty odor from my basement office. My filters lasted around 10 months before an alarm told me it was time to change them. I turned the unit off and ordered replacement filters. the few days this filter was off the musty odors returned immediately! As soon as it was up and running , no more odors, and clean air!

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!

The IQAir XE Series: HealthPro Plus Air Purifier - Smart HyperHEPA performs exactly as it should. Programming is easy. However, it is a bit noisy, so we have placed it in the most central location away from the television. This unit is the size of a piece of furniture, so keep in mind where you want to place it so that it has clear space around it. My respiratory health has been much better over the year since we placed this in our home.

This is a great device. Very reliable and piece of mind. The app lets me access all of the 4 Plus XEs I have throughout the house.

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.

I like the machine for all the reasons stated by others: it works, it's powerful enough, the filters seem to be high quality and intelligently designed, etc. I did alot of research online and I'm glad I did, the world of air purifiers is a confusing one. But this has not disappointed.However, like several other customers I had the dreaded "what is that funky paint/chemical smell coming from the machine?" moment happen a few days ago. I've only had it 3 weeks, but I had read the reviews on here so I knew something was up and that it wasn't just me. I now finally understand what causes it.I spoke with a very helpful fellow at IQAir and he explained that it was probably the V5 filter (i then took apart the machine and tested each filter one at a time in the machine - start with the pre-filter, then add in the V5, then the HEPA - and smelled the air output with each one - yep it was the V5).What happens with the V5 filter is it contains charcoal and it soaks up stuff in the air (odors, chemicals, etc.) whether the machine is running or not. So where the machine is stored, how long it is stored, how it's shipped, the kind of container (styrofoam, plastic?) it is stored and shipped in, etc. can mean that the filter gets lots of "usage" before it ever shows up at your door.The purifier came in a cardboard box inside of a cardboard box, but the filters were not individually wrapped, so I'm pretty sure that it got stored in a warehouse somewhere for too long and just soaked up stuff. Maybe forklift exhaust. :)I called Amazon to get some help. They handle customer service for the actual seller, Mr Vac and Mrs Sew. I explained the problem and they offered me a partial refund on the cost of the purifier, which was enough to get a new V5 filter .So there it is. Now for a few possible solutions that I hope the seller and the manufacturer read and put into practice:- The best solution by far is for IQAir to individually wrap and seal each filter before putting them in boxes and shipping them to re-sellers. Then add a step to assembly where the purchasers take each filter out of the sealed wrapper and put them in the purifier. The machine is pretty simple, adding this step wouldn't be much of a bother for the consumer.IQAir can't control what re-sellers do and where they store things. Yet, if a consumer has this problem, as many of us have, we tend to associate it with the product, that means the IQAir brand takes a hit and I think they should change this process in order to preserve what is otherwise a very superior product.- The next best solution would be alot more work and seems kind of silly, but...the re-sellers would need to be careful about where they store these machines and for how long. They would need a freshness date of some sort and to be stored in a "clean room". I know, it's ridiculous. But it's the only alternative to the first solution I could think of.Again, overall a great machine, but there is one clear improvement they could make and I hope they do.

Great and superior air filter. Very silent. When there is odour from the kitchen, the fan gets faster automatically and returns to slow pace when filtering is done. Perfect for gaz, smells and pollution. I use it next the cats litter. Very efficient. There is a filter monitoring for when one of the three filters needs to be replaced.

Excellent quality

First, it came early so yay! Second, this machine is incredible. I’ve seen it in hospitals, dentists and other medical places. It’s so nice to know the wildfire smoke is not in my home thanks to this baby! Your house smells CLEAN!!!! Sure it’s expensive, but can you put a price on your lungs? Absolutely not.If I want my house to smell like a clean hospital room, I’ll crank it to 6 for 15 minutes! Boom incredibly clean! So so so pleased! Thank you iq air, for making top notch quality products! You have my business for life xoEdit: it’s been 8 months or so, I put a picture on the pre filter and this is what it filtered out of my house. Nasty! I feel so much better knowing I have this machine!

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

The real deal! Excellent!
