Bacteria are just about the #1 problem in Auto odor. This is a Great product that is best sold in the Dealership’s Fix Ops department (i.e. - SERVICE). Over the course of a year, if your vehicle's AC system is left untreated, it will become host to a variety of moisture loving bacteria. Bacteria, such as Serratia, causes odor. Upon engaging the AC system, the exhaust fans blow those foul odors into the air your family breathes. AIRSEPT’s 15 year patented treatment prevents odor and bacteria at the source leaving the auto smelling as fresh as
the day they bought it.
