A few people have asked me how we’re measuring our air quality. We’re doing it with an Elitech Temtop M10 air quality monitor that we picked up on Amazon for about $80.
I really like the Temtop M10. It’s a nice size (a tad bigger than a macbook pro power supply) with a clean design and easy feature set. There’s no wifi or apps or anything like that, just a simple unit with a clear LCD screen and single button that lets you cycle through the various readings (AQI, HCHO, PM2.5, and TVOC.) The LED at the top changes colors from green to read depending on the air quality.
This air quality monitor is rechargeable (comes with USB cable) and seems to run for about 5-6 hours on battery but I keep it plugged in except when doing spot checks in other rooms or outside.
You can get this monitor on Amazon for about $80. If you’re only interested in measuring the wildfire smoke, you could probably get the $60 P10 model which is limited to measuring PM.25 particulates and doesn’t measure formaldehyde or volatile organic compounds. (Though I think wood smoke does contain formaldehyde so if that’s a concern, go with the M10 model.)
