Question:
My car has a bad odor when I run the heater or air conditioner. My friend said I might need a new cabin air filter – what's that?

Morgan Park Auto Service Answer:
A cabin air filter is a special filter that cleans the air that comes into the Chicago drivers' passenger compartments – or cabin – of their vehicles. Most new vehicles sold in IL now have a cabin air filter. A cabin air filter catches dust, pollen, spores and other pollutants before they can get into your cabin. It's kind of like the filter on your furnace in your Chicago home, cleaning the air you breathe inside your vehicle.

As Chicago drivers can imagine, it eventually gets filled up and can even start to get smelly. So – you just have it replaced. Now some are really easy to access and others are tougher to get to. Your friendly and knowledgeable Morgan Park Auto Service will be able to take care of it for you.

Your 's owner's manual likely has a recommendation for when to replace the cabin air filter. If you live and drive in IL where there is a lot of dust, pollen or pollution, the filter will fill up more quickly. Of course, if you're getting a bad odor, bring it to the attention of your friendly and knowledgeable Morgan Park Auto Service service advisor.
