That smoky haze can still make you cough even when you're inside your car driving with the windows closed.
Ash and pollen that collects on the windshield make its way into the air inlet until it reaches your cabin air filter.
Fresno mechanic Rusty Rasmussen says they're not designed to keep out fine particulate matter but they are helpful in trapping dirt, pet dander, and pollen.
"In our current situation they're going to get more exposure to the soot and ash that's in the air," he says.
So it's important you have them checked or changed.
Clogged cabin filters restrict air flow.
"Sometimes you'll find pet hair, lint, bugs," says Rasmussen. "Sometimes it will get so bad it will create a whistle from the air restriction. And then depending on what kind of stuff is on it, it can create sort of a funky smell."
Rasmussen says air filters under the hood as well as the cabin filter are often overlooked.
