ATP RA-3  Carbon Activated Premium Cabin Air Filter
ATP Carbon Activated Premium Cabin Air Filters offer the highest level of protection.  Outside air flowing thru the vents often contains impurities and even obnoxious odors (like diesel fumes).  The ATP Premium Filter has a static electrical charge which traps particles before they enter the passenger compartment.  Activated carbon then absorbs obnoxious odors resulting in cleaner air for you and your family.
