The Awair is beatifully designed and packaged and the app is excellent. The quality of the sensor data seems good, and the charting and recommendations in the app are really well done.

It wasn't until I decided I should put them side by side to see how the first edition stacks up with the second that I realized that the readings are ALL OVER THE PLACE! I've noticed that the 1st generation consistently rated indoor pollution and dust much worse than the 2nd generation, even though the 2nd generation was supposed to be more sensitive. I couldn't even get the temperature to line up.
I went to their website hoping I could call tech support to see if there is an update to firmware I could download only to realize they don't even have a phone number listed. I have to fill out a form and wait for someone to contact me back. Days later, I finally got a message that tells me they "calibrated" my units. As far as I could tell, they just made sure all of the units under my account that have the same name, like "Master Bedroom" or "Kids' Room" show the same reading. However, if I put a "Master bedroom" unit next to a "Kids Room" unit, the readings are still vastly different. I know for sure my chemical and dust level are incorrect with at least two of my machines because it's sitting in a room which I never open the window but is dust piled because it's carpeted and is my dog's favorite room to hang out. They told me that I have to wait a few days for the data to normalize. When I did wait for it, nothing changed. Now, i've gone past Amazon's return period because i waited for Awair's website to reply and waited for the readings to normalize.
I really want this to be a fluke because I really wanted a device like this to work. But I can't think of any reason why these readings would be so off from each other, and that they can "calibrate it" so that machines with similar room names would end up having similar readings.
Update: 1/23/19 Several months later and after many back and forth, I finally got to speak with a real human beyond email. They had sent me a replacement 2nd edition some time ago, but the chemical and dust reading is still suspiciously low. After today's call, they said they will send a replacement 1st and another replacement 2nd edition. I'll update my findings. My feeling is that their 1st edition is overly sensitive or dust can accumulate so it read more dusty over time. However, it does work, and shows fluctuations. I think their 2nd edition is trash with useless dust sensor and chemical sensor that is not sensitive enough.
I contacted customer service and they told me that I would have to send in both units for replacements. The fact that *both* of my units experienced this issue does not give me confidence that the replacement units will function reliably into the future. So I returned both.
NOTE: If you need customer service, be aware that there is no phone number to call. You can only contact their "customer success" team 10-6PM Pacific on M-F *via email*. This is absolutely appalling for a product that costs $200.
CO2 levels make a BIG DEAL in the quality of sleep. Sometimes I will need to open the window to bring down CO2 levels and it always seems to make a big difference.
The mobile app (at least on Android) is really well-done with charting over time and notifications when issues arise AND when they are resolved. I've got a $200 hand-held sensor that measures VOC, humidity, temperature and particulates. It aligns very good with this unit.
I would not hesitate to recommend this unit for anyone, not just those with respiratory issues. It will help guide you on how to optimize your air quality and home and it is a bit fun to get your air quality into the 90+ values.
Accuracy is great as well. I compared it with some other instruments I own as well as with the local reported values outside and Awair is pretty spot in.
Finally when I opened the box I was surprised with how small it was. I guess I was expecting something bigger?
It’s powered by USB so I have it plugged into my USB outlet. So no big bulky converter. Just a small USB-C cable that is hidden behind this thing.
I’m glad I waited for the 2nd generation of this product. It works really well and is gorgeously designed.
My experience so far has been that the units are all pretty good at picking up particulate. (When my neighbor smokes while I have an open window, I can easily see the spike on the affected units.) I haven't done a detailed comparison of PM2.5 readings, so I won't focus too much here.
Temperature and humidity also seem to be accurate. (For the reviewer commenting on a 7% difference in humidity readings, that's actually pretty reasonable. Humidity readings are always a bit finicky, especially if different rooms / units are not at the same temperature.)
Where I've really noticed a problem is with the CO2 readings.
From my observations, there are simply units with good CO2 sensors and units with bad ones. (Details below.) I've ordered 8 units so far (with 3 waiting to return) and will likely need one more replacement. Based on this, I would *not* order from the manufacturer. Make sure you buy from a store with an easy return policy, and *test* the units before the return period is up.
On the good units, what I see is that the CO2 readings, when the unit is first plugged in, quickly settle to something at least close to reality. (If you have open windows, the readings should be in the low- to mid-400s.) Over the next week, as the units "calibrate" themselves (scare quotes very much intended), the readings become quite close between the units. Accuracy is nothing like the AirVisual Pro (which I highly recommend in that regard), but is more than good enough for normal use.
On the bad units, CO2 readings usually start fairly high, but quickly settle to exactly 400 ppm and sit there. (400 seems to be the minimum reading these will show, which makes sense, since short of running a CO2 scrubber in your house — which would be slightly ridiculous — you're not going to ever see something much below that.) What appears to happen then is that the "calibration" process simply boosts the signal from the sensor slowly until the readings bottom out close to 400.
If you have only a single unit, this is honestly probably fine. It will tell you when CO2 readings are lower or higher, but *will not* provide accurate readings. As I said, the "calibration" process seems only to boost the signal to make the minimum reading hover slightly above 400, which makes sense since there's really no way for the unit to know what the actual reading is at any given time. All it can do is guess that the lowest reading should be around 400. (This is likely why Awair recommends you expose the unit to "fresh air" at least once a week, as that would provide a somewhat accurate baseline for the CO2 and VOC readings.)
The result is that, as CO2 levels climb on one of the faulty units, the unit *massively* overestimates CO2 concentration. I regularly see CO2 readings well into the 700s on the 3 faulty units I've tested so far. On the units with working CO2 sensors, and on a nearby AirVisual Pro, I rarely see readings above 500 ppm.
Out of curiosity, I did compare serial numbers between the working and faulty units. Based on the range of serial numbers I've received, it *looks* like they're assigned in-order (and are simply hexadecimal). Unfortunately, there's no real pattern to the units with faulty and working CO2 sensors. It truly appears to be random. (Maybe there's an issue with one production line?) With a failure rate of 4 out of 9 units, buyer beware.
UPDATE the Awair has serious build quality issues. The first unit arrived with one LED out on the display. Amazon was quick to exchange. The second unit has been working great until just recently (lasted 2 months) where it sounds like the fan in the unit is going as its making a grinding noise. Amazon is refunding me but I'm not sure if I want to buy this unit again. I want an air quality monitor but I am not sure I can trust Awair anymore.
Honestly it's way too big too. I don't live in a big apartment and this thing claims too much space for what it really is. It's kinda overly embellished with things that don't really add to the functionality. The unlabeled bar graph, and 80s alarm clock styling are a little too bed bath and beyond for my taste, so I ended up tucking it away somewhere where it's probably not getting a great sample of the air.
On a positive note, I can say that the alerts are still interesting to me, but I feel like even they're kinda becoming uninteresting.
I just wish it did more with the data, outside of telling me that a level is high.. Also I wish it were like 5x smaller and 2x less expensive.
I was surprised to see the readings for particles rise and air quality drop after I turned on my oil diffuser - the air quality dropped from around 87% good down to low 70% range! I had been using the diffuser as a mini humidifier at night (with some kind of “sleep better” oils in it) but have since stopped! I use a regular cool air humidifier now and readings are back in the green.
So the short summary is that while I think the device does a decent job of identifying events (e.g., if you burn an egg, it'll register the VOC increase), the actual readings are nonsense. There's very little literature about how VOCs are measured (if you look in the Q&A there's a "contact us" response but no actual answer), but it's clearly done via some software calibration - so unless it calibrates and baselines well (which is doesn't), the readings are completely unreliable. Do yourself a favor and run as far as you can from this thing. Try a Foobot or uHoo - they can spike too, but they seem to self correct after time don't screw up as bad as Awair.
Oh, and Awair customer support is awful too - they take days to respond. Promised to reset a device - and then never did and instead threatened to close the support ticket a few days later.
1. It suggested I buy house plants, so I bought a hundred dollars worth. 2. Would everybody a have the money to buy a 2nd unit? 3. I bought some other filters, activated charcoal for filtering out voc, and etc. Other reading were off also. Lastly, I immediately researched voc. Long term exposure can cause cancer, kidney/liver failure. I bough my 1st unit for peace of mind and got anything but.
