I myself bought an air quality monitor, and am happy I did (uHoo). I have several gas appliances and was concerned about NOx and other possible gases. It turns out everything is about normal, except that CO2 levels in the basement tend to get elevated. I had no idea that this was something that happened. I now make sure to try and air it out down there once in a bit and take breaks more often, since that is where my office is set up.
- c0nsumer 6y agoI bought a CO2 meter for work, with the intention of taking it into (small) conference rooms once in a while to see what happened to the CO2 there. What I found surprised but pleased me: The CO2 levels at my desk are quite low, spike at night when HVAC is off (when the building is empty), but generally during daytime are about the same as being at home with windows open in a suburban area. Granted, it's been more than a year since I've sat at my desk... But still, it was nice to know.
- paulryanrogers 6y agoHow reliable are those devices? Last I looked only the professional ones ($150+) could guarantee independently verified results. Consumer stuff often depended upon calibration and might vary wildly even between two different devices by the same manufacturer.
- dbsmith83 6y agoThe one I have is from https://getuhoo.com/home https://getuhoo.com/home and was around $300. For CO2, it looks like resolution is 1 ppm with a tolerance of ±50 ppm or ±3% of reading (higher of the two). I can't speak to how well it is calibrated since you would need other devices to compare with.
