And the first and most important is track your local air quality.

So the best thing to do is to just be aware that air pollution can cause harm and then where to look for that.

I've got a couple things on my phone.

I have the airnow.gov app and it sends me alerts because I've programmed it to when the air pollution is In my area is actionable to me that and I'll talk about what I would do if there was an actionable alert that came to me.

But it also moves around with me because my phone moves around with me.

So if I'm on vacation, I also can get pollution alerts from other places where and then you can make informed choices about what you're going to do.

An informed choice if the air quality was unhealthy for me, I got kids, is I might ask the kids to not play outside.

You want to look for a fan with a rating of MERV or MERV 13, Stewart said, because these will help filter particle pollution.
