Engine Air Filter vs Cabin Air Filter

Understanding the distinction between the engine air filter and the cabin air filter on your 2018 Lexus LS 500h helps prioritize proper maintenance. The engine air filter prevents dirt and debris from entering the intake, protecting turbocharged or naturally aspirated components (the LS 500h’s 3.5L V6) and helping maintain fuel efficiency and performance. The cabin air filter, in contrast, improves interior air quality and passenger comfort by removing pollen, dust, and particulates before they enter the cabin. Both filters are inexpensive preventive measures compared to the potential cost of engine repairs or degraded HVAC performance. At Stevinson Lexus of Frederick we install OEM filters and provide documented inspections so you understand the condition and value of each service. Repairs covered under warranty must be performed at a certified dealership to preserve coverage; our factory-trained technicians and clear pricing ensure long-term savings and peace of mind.
