There’s a risk that a motor could burn out prematurely, leading to more expensive repairs and potentially impairing climate control functionalities.

Effects of a Clogged Cabin Air Filter

When a cabin air filter becomes clogged, it leads to a series of problems impacting air quality and vehicle function. I’ll discuss how airflow is reduced, contaminants build up, and the potential for damage increases.

Reduction in Air Flow

A clogged filter can drastically reduce the airflow through the HVAC system.

I have found that this limited airflow often results from accumulated pollen, dust, and debris blocking the filter’s pleats.

This blockage can make it feel like very little air is coming through the vents, despite the fan or blower motor working overtime.

Buildup of Contaminants

When the filter is congested, its ability to trap pollen, smoke, odor, and other contaminants is compromised.

This means that instead of capturing these pollutants, the filter may allow them to enter the car’s interior, directly affecting the air quality.

I’ve noticed that particularly in high pollution areas, a clogged filter can lead to a noticeable increase in dirt and dust inside the vehicle.

Potential for Damage

A filter left unchanged can result in more than just discomfort.

The strain on the HVAC system from a weak airflow can cause serious damage.
