Air Filter vs. Cabin Filter: What's the Difference?
An Air Filter cleans intake air for engines, while a Cabin Filter purifies the air inside a vehicle's cabin.
The Air Filter is responsible for ensuring that the air pulled into an engine is free of contaminants, ensuring optimal combustion and engine health. On the other hand, the Cabin Filter focuses on ensuring that the air circulating inside a vehicle's passenger compartment is clean, free of pollutants, and allergens.
The Air Filter is typically located in the engine bay and is part of the engine's intake system. In contrast, the Cabin Filter is usually found behind the glovebox or under the dashboard and is a part of the vehicle's HVAC system.
While the Air Filter ensures that harmful contaminants like dirt and dust don't enter the engine, potentially causing damage, the Cabin Filter ensures that passengers are not exposed to external pollutants like pollen, smog, or dust.
Regular checks and replacements are essential for the Air Filter to ensure the engine runs efficiently. The Cabin Filter, too, requires periodic replacement to maintain air quality inside the vehicle.
A clogged Air Filter can reduce engine efficiency and increase fuel consumption. Simultaneously, a dirty Cabin Filter can worsen allergies, reduce the efficiency of the HVAC system, and leave an unpleasant odor in the car.
