Symptoms of a failing Cabin Air Filter

Bad smells

Are we on the Old Town Road? No? Then why does it smell like it in your car? Look, I shouldn’t have to break this down for you, since you presumably read the description above. But a cabin air filter keeps dirt, dust, and other particles from entering your car. So, if your filter isn’t doing it’s job, you’re likely going to pick up on some funk odors.

Scheduled maintenance

Your two favorite words in the world! You’re just such a huge fan of scheduled vehicle maintenance, aren’t you? If you rarely look at your maintenance schedule, you should probably break that habit. Because if you do, you might just save a ton of money. When it comes to cabin air filters, there is always a specified timeframe that is outlined by the manufacturer. We trust them, and you should too.

Visibly dirty

Look. I know you’re probably not checking your cabin air filter on the daily, but it wouldn’t hurt you to give it a try. Considering the filter is white when it’s nice a new, you’ll definitely notice when it’s dirty and covered in dust, dirt, and other debris.

Poor heater and A/C performance:

A severely clogged cabin filter can also cause a reduction in the performance of your heating and air conditioning systems. I’m sure I don’t need to tell you that your lack of heating or AC will cause some discomfort for you and your passengers.... This alone is a good sign that you should replace your filter.
