Wildfire smoke can make the sky look dramatic, but health experts say the more serious threat is often invisible. Tiny particles carried in the haze can affect the air people breathe and raise health concerns, even for those staying inside.
Officials recommend remaining indoors when smoke levels are high, but that alone may not be enough. Smoke can still find its way into a house through small openings, and some cooling systems can pull polluted air from outside if they are not set properly.
To improve indoor air during wildfire events, experts advise using an air filter or putting together a simple homemade filter. They also say to check window air conditioners to make sure they are not drawing in outdoor air, and to seal drafts around the home so less smoke can slip inside.
These steps can help create a cleaner indoor space while smoky conditions persist outdoors. During wildfire episodes, reducing the amount of polluted air that enters the home can make indoor sheltering more effective.
