I had one for a year, but began seeing suspiciously high TVOCs when my furnace turned on. So I got a second one, then performed the TVOC calibration in the app, and they were within 20% ppb of each other consistently, which is actually quite good for TVOC sensing. The rest of the metrics were within 1%.
BUT, I was still seeing high TVOCs correlated with my furnace turning on. After trying new filters, and venting rates, I finally tried to dehumidify the air intake into the furnace. BINGO. The TVOCs dropped to from a having peaks of 3000 ppb to about 400 ppb (its been a few weeks now).
It turns out that our exceptionally cold and wet winter in California makes combustion of the humid air “run rich”, meaning that there was a higher fuel-to-air ratio. This leads to uncombusted hydrocarbons in the exhausted air.
I am so glad I had this device to even know that this was a problem to fix.

Don't buy - tricky VOC readings, and short historical data retention
I used to hold a positive opinion of their air quality monitors, which is why I made the unfortunate decision to purchase seven of their devices and scatter them throughout my home. However, my perception has taken a nosedive due to the significant issues I've encountered this year. Here are my observations:1. Tricky VOC Readings:When I acquired a new device from Awair this year, I conducted an alcohol drop test to assess its performance. A reasonable device should display a noticeable increase in VOC readings in response to the alcohol drop.During the test, I put the new device (the one named Roaming) side by side to an old device in the Dining Room (as shown in the picture), then dropped one droplet of alcohol in front of them. I also dropped another droplet of alcohol in front of the device in the South Bedroom.To my astonishment, both of the old devices in separate rooms provided identical readings (38820, as indicated in the picture) during the test. Is it sheer luck that two drops of alcohol coincidentally triggered precisely the same VOC level on both devices, accurate to 4+ digits?Also, the new device consistently displayed significantly lower VOC readings. For instance, in the screenshots from the second picture, the two devices positioned side by side have their VOC readings for the same alcohol drop differ by a whopping 32000 units. Additionally, you can observe from the picture that the right device (the new one) responds to VOCs more slowly than the old one and remains stuck at a 'perfect' VOC reading (a single dot).This happened to a device I purchased this year, and a replacement they sent to me later. I didn't bother asking for another replacement.2. Reduction in Historical Data Storage:Initially, these monitors allowed for the storage of one year's worth of historical data in the cloud.However, they have since reduced this capacity to just one month. Unfortunately, their app lacks a feature for local data storage, and their so-called 'export' feature forces users to export data device by device, through quite a few button presses. This can be quite a hassle for individuals like me who own multiple devices from this company.
