Engine Air Filter vs Cabin Air Filter

Understanding the difference between the engine air filter and the cabin air filter on your 2020 Lexus RX 450h helps protect both vehicle performance and passenger comfort. The engine air filter filters intake air for combustion, preserving horsepower, fuel efficiency, and hybrid system longevity; a clogged engine filter can reduce acceleration and increase fuel use. The cabin air filter, by contrast, filters the air you breathe inside the vehicle, capturing pollen, dust, and odors. Both filters play distinct roles but are equally important to maintain—ignored filters can lead to bigger, costlier repairs or reduced comfort. At Stevinson Lexus of Frederick we inspect both filters during routine maintenance and recommend OEM replacements performed by certified technicians. Choosing dealership service often provides better immediate pricing and greater long-term savings thanks to accurate diagnostics, proper installation, and valid warranties.
