What It Helps Address

• Odor intrusion from nearby vehicle exhaust where odor-reducing media is applicable in the line

Replace the cabin air filter at the interval recommended by the vehicle manufacturer or during HVAC service if airflow or cabin air quality declines. Confirm the filter dimensions, style, and housing design before installation. For HD truck and commercial vehicle maintenance, compare the old filter to the WP10278 panel shape and size to ensure correct placement in the HVAC filter tray.
