The cabin air filters inside a vehicle’s HVAC system plays an integral part in the car’s HVAC system. It is the sole component that keeps you from inhaling the contaminants and particles suspended in the air outside.
There is plenty that can go wrong when the air filter is in bad shape. For instance, overtime, the air filter will need replacement due to an overload of dirt and debris. Make sure to bring it in so we can advise a maintenance schedule for you.
This will have an impact on the cabin’s cooling capacity and the performance of the HVAC system will become noticeably poor. For a better understanding of the filter’s role, you have to get thorough information on how the HVAC system functions.
Cabin Air Filter for your Vehicle
Your vehicle’s climate control system drags fresh air into the vent that you can find under the hood. This vent locates near the engine bay. The vents in your car are designed separately and compartmentalized away from the combustion engine so that they can stay safe from the heat.
Keep in mind that their position is in the base of the windshield. This is where the car experiences the most air pressure when driving. This is important because the system needs a high supply of air to work. Once this air enters through the vents, it enters into the heater box.
The heater box contains all the integral components of the climate system. These include all the heating and cooling elements such as the blower motor and more importantly, the cabin air filter. As the air enters through the vent and into the heater box, the first point of contact for the air is the cabin air filter.
The cabin air filter is a layered component that has plenty of tiny insertions and materials that help trap contaminating particles of the air. For instance, it traps dirt, spores, mold and other large particles first. It is also equipped with an activated charcoal section, absorbs the odor causing contaminants that help keep your cabin odor free. This part of the filter helps eradicate any bad outside smell from entering the car.
Blower Motor
From the cabin air filter, the air passes into the blower motor, which regulates the pressure of air by dictating the amount of air that is being pulled from the air vents. If you moderate the fan speed inside the cabin, then the resisters of the blower motor are at play. From there, the air channels through the heat exchanger. This is also known as the evaporator, and this component is where most of the heating and cooling takes place.
As you can see, your vehicle’s heating and cooling system is very complex and the cabin air filter initiates the ventilation process. Having an air filter that is worn out will therefore lead to many issues concerning air quality.
