What We Do

  • Inspect the cabin air filter(s), which can be in difficult to reach locations, and determine if it requires replacement. Some cars use two filters.
  • Educate you about the cabin air filter, and replace it if you desire.

Why We Do It

  • A cabin air filter cleans air entering your car through the car’s air, heater, and air conditioner vents.
  • The concentration of unfiltered pollutants inside your vehicle can be more than six times higher than the outside air.
  • Removes air pollutants that can cause health problems.
  • The Bottom Line: Replacing the cabin air filter(s) is good for the health of the vehicle’s occupants.

What Does the Cabin Air Filter Do?

The cabin filter in your vehicle is responsible for filtering the air before it enters the vehicle’s cabin. The cabin air filter catches pollen, dust, dirt and other impurities from the air, keeping the air purified for the vehicle and its passengers. It’s important to keep the cabin air filter clean so when the heater or air conditioner is running, the air being emitted is quality air. The cabin air filter should be replaced every 15,000 to 30,000 miles or as needed.

How Does a Micron Cabin Air Filter Work?

Filters out 99.5% of airborne dust, pollen mold spores, and bacteria particles (as small as 2 microns). Electrostatically charged fibers polarize particles in the air and captures them in the filter medium.
