Engine Air Filter vs Cabin Air Filter

The 2021 Lexus RX 450h has two critical filtration roles: the engine air filter safeguards engine and hybrid component performance, while the cabin air filter protects interior air quality for occupants. The engine filter prevents dust, pollen, and road debris from entering the intake system, preserving the RX 450h’s horsepower, fuel economy, and emissions control. The cabin filter traps pollen, allergens, and particulates so passengers enjoy cleaner air inside the vehicle. At Stevinson Lexus of Frederick we explain these differences clearly and show you the physical condition of each filter during service. Our certified technicians use OEM parts to maintain factory tolerances; this attention to detail helps prevent performance loss and recurring repairs. Regular inspection and timely replacement of both filters are simple, cost-effective steps that protect long-term vehicle value. To arrange a combined inspection and replacement with transparent pricing and warranty coverage, schedule appointment online and review current service specials.
