What is an in-cabin microfilter?

An in-cabin microfilter is an essential feature in modern vehicles that helps maintain clean and fresh air inside the car. This filter is designed to trap and remove dust, pollen, pollutants, and even some odors from the air circulating through the cabin. By effectively filtering the air, it helps to provide a healthier and more comfortable environment for both the driver and passengers. The in-cabin microfilter is particularly beneficial for individuals with allergies or respiratory sensitivities, as it helps to reduce the presence of airborne irritants.

What does an in-cabin microfilter actually do?

The filter prevents dust, pollen, and other airborne particles from entering the passenger compartment, while allowing air to enter and circulate freely. This helps to keep the air in the cabin fresh and clean. The in-cabin microfilter is typically located in the vehicle’s HVAC system, which is the system responsible for controlling the temperature and airflow in the cabin. 

 

In addition to protecting passengers from dust, pollen, and other airborne particles, the in-cabin microfilter also helps to extend the life of the vehicle’s HVAC system. By trapping the dirt and pollen, it helps to reduce the amount of wear and tear on the system, which helps to ensure that the system will last longer. It is important to replace the in-cabin microfilter regularly, as the filter will become clogged with dirt and pollen over time. Nissan typically recommends that the filter be replaced every 10,000 to 15,000 miles or once per year.
