Cabin Filters

The air that enters the interior through the heating, ventilation, and air conditioning system is cleaned by the cabin filter, a feature present in the majority of recent models of cars. It collects dust, pollen, and other airborne particles that can be uncomfortable to ride in a car, especially if you have allergies or other respiratory issues.

Manufacturers have different recommendations for how frequently to replace cabin filters; some advise every 12,000 or 15,000 kilometres, while others recommend replacing them more frequently, depending on how much and where you travel. The maintenance schedule in your owner’s manual should be reviewed. The cabin air filter may need to be changed yearly or perhaps more frequently if you commute in heavy traffic in a location with poor air quality. That might also be the case in an environment like a desert where there is a lot of dust to filter out.

Reduced airflow through your temperature control system, such as when you crank up the fan too high and get more noise than results, are some indications that you need a new cabin air filter. Bad scents that linger are another. Although you might be able to check the air filter yourself, you should have it checked at least once a year even if you don’t have any warnings.

The owner’s manual for your car should have instructions on how to remove the glove box’s screws and access the cabin filter that is situated behind it. Other cabin air filters can be found either under the hood, where fresh air enters the climate control system or under the dashboard, both of which may be difficult to access.
