I spent $800 on a portable air quality monitor and it completely changed how I feel about chemtrail theories

Back in May I dropped $800 on a PurpleAir monitor to keep track of stuff inside my house after all that smoke from the Canada fires drifted down. At first I just wanted to know when to close windows. But then I started comparing my outdoor readings to the government data from the EPA site near my house in Portland. My monitor showed spikes in particulate matter that their station missed by hours sometimes. That got me looking into how they measure things and where they put their sensors. Now I don't buy the whole chemtrail thing being a secret government plot but I do think they downplay air quality issues more than they let on. My readings were 30 points higher than theirs on three separate days last month. Has anyone else here run their own tests and seen big differences from official numbers?

I read a study that found personal monitors often read 20-40% higher than government stations.

Wait isn't that basically saying the personal ones are just wrong all the time though... like if they're always higher then they're not really giving you useful data compared to the official stations. The problem is people trust their little device on their porch more than the government setup down the street, but if that study is right then you're just panicking over fake numbers. I saw something similar that said the difference comes from where you put the monitor, like right next to a hot driveway or under a tree can mess with the reading big time.
