Why does my Subaru have 2 air filters?

Why Subaru Has 2 Air Filters
Subaru vehicles are equipped with two air filters for different purposes:
1. Engine Air Filter: The engine air filter helps keep contaminants from entering the engine and should be replaced every 15,000-30,000 miles in normal driving conditions. It is essential for maintaining the engine’s life, increasing fuel efficiency, and reducing emissions.
2. Cabin Air Filter: The cabin air filter helps to clean the air you breathe inside the vehicle and should be replaced every 15,000 miles. This is important for ensuring clean air inside the cabin, especially for adventurous Subaru owners who may encounter more dust, pollen, and insects during off-road trips.
Both air filters serve distinct purposes in maintaining the vehicle’s performance and ensuring a clean and healthy driving environment.
