Engine Air Filter vs Cabin Air Filter

The cabin air filter focuses on interior air quality, reducing allergens and particulate matter that impact occupants. Both filters contribute to overall vehicle health: a clogged engine filter can reduce power and efficiency, while a blocked cabin filter strains the HVAC system. At Larry H.
