I've wondered if air quality was an issue where I live but wanted to also be able to do something about it so I bought and air purifier with an air quality sensor (Winix D480). It mostly kicks up in the morning but I have no idea what is causing it to think the air quality is bad. For those who've gotten a real sensor how do you track what's actually causing the air quality issues so you can do something about it? I live close (1400ft / 444m) to a major highway so I've wondered if that could be a "source" but no idea how to tell.
