FRAM Fresh Breeze Cabin Air Filters prevent road dust dirt and pollen particles from entering your vehicle’s air conditioning heating and ventilation system. FRAM Fresh Breeze is the only cabin air filter that uses ARM & HANMMERTM baking soda to absorb odors. Activated carbon embedded in the filter freshens the air before you breathe it. The air outside your vehicle can be up to six times dirtier than the air outside. Protect your family from dirt dust and allergens with a FRAM Fresh Breeze Cabin Air Filter.
