Cabin Air Filter Servicing in Towson, MD

Similar to the furnace filter in a house, the cabin air filter helps clean the air that is brought into the cabin from outside the vehicle. This is an often-overlooked component of the vehicle’s HVAC system that provides relief to individuals with allergies and helps reduce odors in the cabin.

A cabin air filter is a pleated filter made from paper cotton, fabric and other materials. It is usually located behind the glovebox, depending on your car’s make and model. It works to remove pollutants, such as dirt, dust, smoke, exhaust gas, and pollen, from the air you breathe while in the car. The fan or fans of the HVAC system pull external air into the vehicle, pushing it through A/C elements, regulating its temperature, and blowing it through the filter. It cleans the air as it moves through the system and blows into the car.

Problems with your cabin air filter can affect the quality of the air in your vehicle. A clogged or damaged filter can cause the air system’s blower motor, which pushes the air through the vents, to malfunction.

Some common signs of a bad cabin air filter include:

    • Reduced air flow through vents
    • Whistling noise from air vents
    • Strange odors inside the car
    • Increased fan noise

Every part of your car’s A/C system needs to be in optimal shape in order for it to function properly. In general, an air conditioning repair technician should change your cabin air filter every 12 months or 12,000 miles, unless your owner’s manual states otherwise. However, depending on your driving conditions and the current climate and season, you may need to change it earlier or more often. Bring your car into Hollenshade’s, and our mechanics will keep your cabin air filter clean and functioning at its best.
