Smoke got you down? Just wait until your car or truck start to react to the smoke and ash. There is one and maybe even a second air filter in your vehicle. The first and most critical is the air filter which removes dust, dirt and ASH that is in the air the engine breathes. The other (and sometimes there are two) are called cabin air filters which filter the air that comes into the cabin of the car and with which we air condition and breathe. Make sure you have these critical air filters checked to ensure your car and your lungs can operate at full capacity. The last big forest fire we had here in northern Colorado we pulled out lots of really dirty, black filters and expect to see more soon. For top performance, you need all the air you can get into your engine and not have it restricted by smoke and ash residue. Same for your lungs!
