What does the car cabin filter do?
When the car is moving, a great deal of air enters the passenger compartment through the vents of the heating, ventilation, and air conditioning system. This air contains dust, abrasive particles, soot, plant pollen, harmful gases, etc. Inhalation of these substances can cause respiratory problems and allergies. The cabin filter helps to solve this problem by cleaning the air supplied to the cabin.
Can I drive without the cabin air filter?
Removing the cabin filter won’t cause critical damage to the car. However, uncleaned air will get inside. Since the passenger compartment space is enclosed, the concentration of harmful substances in it can be several times higher than outside. In addition to harm to health, this may cause premature clogging of the heater core, as well as increased dust concentration in the car interior.
How often should I change the cabin filter?
This part should be replaced on average every 15,000 km or once a year regardless of the mileage. It also needs to be changed in case of reduced ventilation efficiency, bad odours in the car interior, and windows fogging up.
A clogged filter element may cause the heater and air conditioner to malfunction. Although the air is properly heated and cooled, its flow is weak. This creates an increased load on the passenger compartment fan, thus leading to its premature breakdown. However, despite the strong connection between engine cooling and air conditioning systems, the efficiency of the former is not affected by the condition of the cabin filter.
