Keep the inside of your vehicle fresh with the FRAM CF10372 Cabin Air Filter. It's made with a combination of carbon and baking soda to clean the outside air as it comes into the cabin through the vent system. Odors are absorbed and 98 percent of dust, pollen and other particles and allergens ranging in size from five to 100 microns are captured. Putting in a fresh air filter at regular intervals (once a year or every 15,000 miles) not only maintains the breathing quality inside the vehicle but also helps ensure that the defrosting system and air conditioning continue to work efficiently. It's easy to install in a location behind the glove box. This car cabin air filter is compatible with the Mazda 6 manufactured between 2003 and 2008.
