Air Filter vs. Cabin Filter: What's the Difference?
Edited by Sumera Saeed || By Sawaira Riaz || Published on October 25, 2023
An Air Filter cleans intake air for engines, while a Cabin Filter purifies the air inside a vehicle's cabin.
Key Differences
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.
