I was a bit worried about air quality in my shop where I run the laser and a CNC machine. I found this inexpensive air quality monitor in Amazon and I have been really happy with it so far. Just posting in case anyone else is concerned about their air quality.
I also have the Lightburn file for the different ranges of PM2.5 and PM10
