@josh I’d like to get a monitor or two. Hope you don’t mind that I share a few things here. One issue I have is that many monitors seem to be “smart” devices and I wonder if they work when wi-fi is down. And are VOC readings more reliable now? Everybody and their mom has a “best air quality monitors” article on their website, but they seem to have stopped mentioning the unreliability of VOC readings, and none are looking at PurpleAir?
