Luber-finer cabin air filter helps trap bacteria, dust, pollen and exhaust gases that come through your vehicle‘s ventilation system. Cabin filters are particularly beneficial for people with allergies. Luber-finer cabin air filters should be replaced according to owner's manual guidelines. You may want to change the filters on a seasonal basis because of the pollutants created in different seasons. The importance of cabin air filters maintenance is simple. Think of them as an air filter that cleans air before it enters the cab‘s interior through the heating, air conditioning or fresh air systems. The filters remove allergens and pollutants before they get into the cab and before the driver and passengers can inhale them. Our filter traps virtually all pollen and dust particles that may cause allergic reactions. Roadside air contains significant numbers of contaminants such as pollen, dust, diesel soot and smog. These contaminants are two to six times more concentrated inside the cab than outside. The filters greatly reduce the amount of dust and pollutants entering the cab, so inside glass, dashboards, heating, ventilating and air conditioning systems do tend to stay cleaner
