So, what is a cabin air filter, exactly? Essentially, it’s a filter that’s designed to trap dust, pollen, and other airborne particles before they enter your car’s cabin through the ventilation system. The filter is typically made of pleated paper material, but can also be made of other materials like activated carbon, which can help trap unpleasant odors and harmful gases.

The cabin air filter is responsible for trapping all kinds of particles, from microscopic allergens to larger debris like leaves and bugs. Over time, the filter can become clogged with these particles, which can reduce the airflow into your car’s cabin and lead to a musty or unpleasant odor.

That’s why it’s important to replace your cabin air filter on a regular basis. How often you need to replace it can vary depending on the make and model of your vehicle, as well as driving conditions like dust and pollution levels. As a general rule of thumb, it’s a good idea to replace your cabin air filter at least once a year or every 12,000-15,000 miles, whichever comes first.
