Is it necessary to replace the cabin filter (also known as the pollen filter) in a vehicle?

Question

DentroTest · Accepted Answer

Yes, the cabin filter is a wear-and-tear item with limited capacity. Its function is to ensure interior air quality and protect occupants from particles such as dust, soot, and pollen. The correct answer states it should be changed especially at the beginning of spring, as this is the season with the highest concentration of allergens, and the filter needs to be clean to be effective. A saturated filter reduces airflow (making it harder to demist windows) and can cause driver fatigue or allergic reactions. The other answers are incorrect because these filters do not 'self-clean,' and their replacement depends on usage and mileage (generally every 15,000-30,000 km or 1 year), not on a mandatory technical inspection every six months.
