Do you hear a whistle sound coming from the cabin air intake ducts? Is the airflow weak, even when the heating or air conditioning is high? If so, it may be time to replace your cabin air filter. This small pleated filter is made of multi-fiber paper cotton or other engineering material and is usually located behind the glove compartment. It helps remove harmful contaminants, such as pollen and dust, from the air you breathe inside the car. If you notice that your car has an unpleasant odor or that airflow has decreased, it's time to consider replacing the cabin filter.
Before entering the passenger compartment, outside air is directed through this filter to trap contaminants inside the filter and prevent them from entering the interior of your vehicle. One of the first signs that you need to replace the air filter is weak ventilation airflow into the cabin. This may be due to buildup in the filter itself, which is common if you drive on dusty roads or live where there is a higher level of air pollutants, such as pollen. If the air conditioner blows weakly even with the highest fan setting, the filter may be clogged.
The main sign of a problem is smell. If there is a musty smell that you can't attribute to anything else, this could be a sign that the air filter is dirty or clogged in some way. Cabin air filters that are blocked or clogged do not allow air to pass easily, and that can cause a strange high-pitched groan behind the dashboard or even cause the air conditioning system to sound louder. According to Prokopenko, the air filter is “one of the most overlooked maintenance items in a car”.
If you are driving in heavily polluted areas or traveling on dirt roads, you should change your cabin air filter every 5,000 miles. Recommendations for when to replace a cabin air filter vary by manufacturer, with some saying every 12,000 or 15,000 miles, others more and frequency may depend on how much you drive and where. In your car's owner's manual, you can find mileage marks for recommended cabin air filter changes, although they vary by vehicle type and manufacturer.
