What is a Cabin Air Filter?
A cabin air filter is a component located in the HVAC (Heating, Ventilation, and Air Conditioning) system of your vehicle. It is designed to remove pollutants, allergens, and other particles from the air that enters the cabin, providing you with a more comfortable and healthier driving experience. The cabin air filter is different from the engine air filter, which is responsible for cleaning the air that goes into the engine.
Signs It's Time to Replace the Cabin Air Filter

- Reduced airflow from the vents: If you notice a decrease in the amount of air coming from the vents, it could be a sign that the cabin air filter is clogged and needs to be replaced.
