Stopped working after 4 months. Seller did not offer a warranty. I called the head office and an investigation on the seller has commenced. The company only has an email address to reach out to them.

Donde puedo arreglar mi Airdoctor?

This machine has been excellent so far. I use it in my second hand store and it has done an excellent job to improve our air quality. I have an employee who has health issues and was concerned about Covid etc so she is the main reason why I bought the machine. I am not 100% positive that it will remove everything from the air but we are happy with it. It is very quiet and doesn't take up a lot of space and so far hasn't required any maintenance. This is a good value for the money and I would recommend this machine to everyone.

Bought this to try and clean out an apartment unit that was absolutely pungent with second/third hand cigarette smoke from the neighbor. What pulled me in was the promise of the large treatable area (over 1000 sq ft) and the ultra HEPA filter that filters particles smaller than usual - small enough to filter smoke particles. With that and the ionizing feature and the coconut carbon filter, I thought I'd be set. Upon setting up the purifier in the unit's living room, I, like a few others, noticed a plastic-y smell the first time I turned it (and a second unit I also tested) on...but it went away within a day. I was going to leave it on "Auto" mode but the air quality light went from red to blue in less than two minutes (turning the fan on the lowest setting)...even though the place was clearly contaminated with who-knows-what from the smoke seeping in...so I manually left it on high. The entire apartment unit is only ~850 sq ft, so I expected it to be able to filter everything...and it definitely helped...but I just didn't get the quality I was expecting. The unit still smelled pretty bad upon entering, and I couldn't stand to be in it for more than about 40 minutes before feeling ill (which is a big improvement over not being able to stand it for 10 minutes previously). So I thought, okay, maybe the space is just too open and/or the contaminant (which renews itself quite frequently) is just too strong. So I gave up and put it in the bedroom, which is no more than 300 sq ft, but also along the wall shared with the smoking neighbor. Left there for two days on the second highest setting and with the ionizer on...it completely transformed that room and its closet into a livable space. I was astounded. My clothes, which previously reeked of cigarette smoke, actually went back to smelling good...no trace of smoke at all. It was amazing. There is now, at least, one room in the apartment where I can breathe without complications. Unfortunately, I don't have the funds to dish out for 2-3 more of these to fill the apartment unit with, so I'll likely be keeping one of these and returning the other (and moving out!). Though, speaking of funds, you can find these off Amazon for almost half the price advertised on the AirDoctor website if you just search around a bit.

Does a great job including smells which other purifiers were not very good at that we had. Not sure how contaminated air has to be to get a higher fan level (you can do manual if you like) but even in rooms we know the air quality could be better we still get the blue light for good air. Called the company and they walked me through some tests to make sure the sensor was working and it passed the tests with no problems. So I think the air has to be very dirty before color would change and resulting in the fan automatically increasing the speed. I would recommend using manual mode and choosing your fan speed for the room. Very easy to use and directions simple and understandable.
