Engine Air Filter vs Cabin Air Filter

The 2021 Toyota Mirai benefits from two distinct filtration systems that serve different purposes: the engine (intake) air filter protects the fuel-cell and propulsion-related components by preventing particulates from entering critical airflow paths, while the cabin air filter ensures the occupant compartment receives clean, allergen-minimized air. Maintaining both filters is essential for safety, comfort, and efficiency. In practical terms, a clogged intake filter can reduce range and increase strain on the vehicle's systems, while a neglected cabin filter decreases HVAC performance and passenger comfort. At Larry H. Miller Toyota Peoria, our certified technicians inspect both filters during routine appointments and recommend OEM replacements when needed. We emphasize transparency — you’ll receive clear diagnostics and an estimate before any work begins. To protect warranties and long-term vehicle value, have both filters checked together and take advantage of our service specials and available service financing.
