Does anyone have a sense of where the damage is done regarding PM? I live in SF and our apartment is a block away from a busy road and a gas station, both of which concern me.
Not to mention the wild fires of late depositing ash all over our yard.. Also, being a SF apartment, there isn't A/C so we leave the windows open on hot days.
Is there data around whether an active air filter running in a closed room before we go to sleep will help? Should it just run constantly? Is there any good method to actually lower the amount of PM I'm inhaling?
