I think there are masks you can use outside too. You can also check which times of day/days are worst. And which streets. You can carry the laseregg around for local measures.
- bearforcenine 7y agoPurpleAir also makes an indoor air quality sensor that measures particulate matter: https://www2.purpleair.com/products/purpleair-pa-i-indoor https://www2.purpleair.com/products/purpleair-pa-i-indoor Not sure how it compares with Awair or laseregg. I have no affiliation with PurpleAir, but they are pretty popular in Utah.

So may be better solution are local laboratories with calibrated equipment Masks are tricky. Most "light" masks are for huge particles and can't defend against most of dangerous chemicals Military and science masks are working good against some chemicals and do not protect from another. Except solutions with O2 tanks on your back
