The persistent haze of smoke from the wildfires burning around the Northwest has led many people to wear face masks to protect their lungs. But health officials say many of those masks aren’t doing what the wearers think they are.
As the days of thick, smoky air drag on, you’re seeing more people wearing those little paper masks you can get at the hardware store. Dr. Jim Shames has seen them, too. But, he says, while those masks may filter out some of the ash that’s floating around people need more protection than that.
