If the cabin air filter in a 2008 Toyota Highlander is not changed, it can become clogged with dust, pollen, and debris, leading to reduced air quality inside the vehicle. This can cause the heating and air conditioning systems to work harder, potentially leading to decreased efficiency and increased wear on these components. Additionally, passengers may experience unpleasant odors and reduced airflow, making for an uncomfortable driving experience. Over time, neglecting to change the filter may also lead to potential issues with the HVAC system.
I have found that the filter should be changed around 90K in normal use and 60K in severe conditions. Toyota Tech.
