What happens if you don’t change the cabin air filter enough?
As air comes into your car, the cabin air filter sifts out any dust, pollen, smog, mold, and other junk to keep it from entering your vehicle. It's important to change the cabin air filter regularly—these are some problems that can arise if your filter is overdue for maintenance.
Health Troubles
If dirty air is allowed to enter the cabin of your vehicle, all of the dirt, dust, and foreign particles can decrease the air quality in your car making it harder to breathe and even damaging your interior. A good rule of thumb is to change the cabin air filter every February before spring allergy season arrives but after winter salt and dirt are gone. The new filter will help prevent pollen from making its way into the cabin which can cause you to start sneezing, or worse.Malfunctioning HVAC System
A dirty cabin air filter will also reduce the amount of air flowing from the vents, making the HVAC system work harder than necessary and potentially burning out the motor before its time. That drop in airflow can also affect the temperature of the cabin—both the heat and AC depend on a strong, steady flow of air passing through the heating system.Read more about A/C maintenance and repair.
