The cabin air filter is the first thing that gets overlooked because you don’t really think about it until you take your car to a dealer or a shop. But when you do, it’s the first thing they recommend you change. Just the way your engine needs to have clean air, your passengers need to have clean air too. The cabin air filter not only filters the air that’s coming from the outside, but it also cleans the air that’s being circulated inside the cabin. So, when you are running your air conditioner, you’re not actually taking fresh air from the outside, you are recirculating the air that’s inside.
Here is All You Need To Know About Cabin Air Filter
Please note that not all cars have cabin air filter. Only 80% of the cars built after year 2000 have cabin air filters.
Will a Dirty Cabin Air Filter Affects The AC Performance
Yes. A dirty cabin air filter will affect the AC performance. Why? Because when the cabin air filter gets dirty, the airflow is significantly reduced. The little holes that the filter has are meant for air to circulate through them into the cabin. When they get dirty, they get clogged and very little air can pass, or no air at all. At this point you need to change your cabin air filter or clean your old one and reuse it.
Almost half of the vehicles that come equipped with a cabin air filter are located inside the glove compartment on the passenger side of the vehicle under the dashboard. Simply opening the glove box door, removing or dropping the door will expose the location of the cabin air filter. There should be a plate that can be pushed and pulled out. So, gently remove the old cabin air filter and replace it with a new one.
What Happens If You Don’t Change Your Cabin Air Filter
Did you know that maintaining your cabin air filter is just as important as getting your engine oil changed? Let’s face it. When thinking of car maintenance, the quality of air in your car is usually the last thing that comes to mind.
Two things can happen if you don’t change your cabin air filter:
- Overtime your cabin air filter will get dirty and it won’t be able to hold the allergens, pollutants and unwanted airborne particles, which means all of the above will enter the cabin and you and your passengers will be exposed to them.
- If your cabin air filter is dirty, your AC performance will significantly reduce. You won’t get cold air in the summer and you won’t be able to defrost your windshield in the winter.
Where Is The Cabin Air Filter Located
On most of the cars, the cabin air filter is located behind the glove box. At some cars, it might be located under the hood. Just open the glove box compartment and empty it. Grab the sides of your glove box and squeeze them together and the glove box door will fold down. You will see the cabin air filter frame. There are no screws, you just have to pull it out.

How Do You Know If Your Cabin Air Filter is Bad?

Can You Drive Without Cabin Air Filter
Technically, yes. You can drive your car without cabin air filter installed. But should you do so?

How Often Should I Change My Cabin Air Filter

It is recommended that you change your cabin air filter at the same time you change your engine air filter.

Pull out the frame and discard the old cabin air filter and insert the new cabin air filter into the frame.

Make sure that your cabin air filter is not damaged before reinstalling it.
