1. Reduced Airflow: If airflow from the vents has decreased significantly, it may indicate a clogged filter.
2. Unpleasant Odors: Foul smells can occur if the filter has become damp or contaminated.
3. Increased Dust or Allergens: If you notice more dust inside your car or experience increased allergy symptoms, it might be time for a change.
4. Noise from the HVAC System: Unusual noises when the fan is running may suggest an obstructed or damaged cabin filter.
