Engine Air Filter vs Cabin Air Filter

The cabin air filter, by contrast, protects the HVAC system and the occupants from pollen, dust, and airborne contaminants. Maintaining both filters helps preserve the refined driving experience that Lexus owners expect while preventing avoidable repairs and preserving resale value. At Stevinson Lexus of Frederick in Frederick, CO, our certified technicians evaluate both filters during routine inspections and provide transparent recommendations based on OEM standards and local driving conditions.
