Something may be doing over my head, but I have to ask: is this a fart/diaper joke?

No, my neighbors weed smoke was coming through her closet and raising particulate matter. He’s moved out but we’ve kept the automation and it also cranks up the air purifier.

I did hear about the farting causing VOCs to rise and that kind of happens with us too.

My guess would be to prevent smoking or vaping

may have a CO2/pollen/particulate detector, and/or child could have asthma/allergies.
