However, you may want to consider a lot of factors to make this decision. The frequency of changing the filter will be higher based on road conditions, driving habits, and the condition of the HVAC system, just to name a few.

If you notice that the air conditioning system is not working properly, chances are that you need to replace the filter.

Besides, if the HVAC system produces nasty odors or you hear a whistling sound from the air intake, or your HVAC system is not producing enough cool air or hot air, you may want to check this part and replace it.

It is important to note that if you drive in extreme temperatures, such as a desert, you may want to replace the cabin air filter more frequently. In the same way, if you drive through polluted areas on a regular basis, it will require more frequent replacement.
