Purolator Heavy Duty Cabin Air Filters are used to trap bacteria, dust, pollen and exhaust gases that come through your vehicle's ventilation system. They work in the same way as your home's furnace filters by cleaning the air before it enters the cabins' interior through the vents. Cabin air filters are particularly beneficial for people with allergies and trap up to 100% of harmful pollutants before you inhale them.
By greatly reducing the amount of dust and pollutants entering the cab, Purolator Heavy Duty Cabin Air Filters help the windshield, dashboards, heating, ventilating and air conditioning systems to stay cleaner.
