Why Is Changing Cabin Air Filters Important?

When it comes to auto maintenance, most drivers tend to forget or not bother with replacing their filters, specifically the cabin air filter. Even though this filter doesn’t directly affect your vehicle’s functionality, it can cause an unfavorable atmosphere inside your car. Here are several reasons why you should change your cabin air filter on time:

  1. Bad Odors - Since the cabin filter is responsible for keeping out dirt, dust, and other pollutants, leaving it to build up can cause a stench. It might smell musty and overall unpleasant whenever you turn on the A/C or heat. Therefore, changing your cabin air filter can help deliver odorless, clean air to the passenger cabin.
  2. Increase Allergies - Air filters trap pollen and dust, which can be harmful to you. If you or your family members have sensitivities to these air pollutants, it can be very uncomfortable for you or them to be inside the car.
  3. Foggy Windows - A dirty cabin filter will clog up the HVAC system. Therefore, it can impact the airflow toward your windshield and windows. If your windows have trouble clearing out, you may want to take a look at the filter.
  4. Poor HVAC Performance - As mentioned above, a clogged cabin air filter may make your overall HVAC system work harder than it needs to. For example, it can cause the motor to overwork to supply the cabin with heat or air. If you want the smooth operation of the HVAC system, simply remember to change this filter periodically.

If you’re not sure how often you should swap the cabin air filter out, you can look at the owner’s handbook for a recommended interval or have it inspected by the technician during your next oil change.
