"Many airborne particles found inside cars are less than one micron in diameter. Yet, these fine particles, according to research, pose health risks because their small size can penetrate the deepest portions of the lungs," said Matt Trerotola, vice president and general manager of DuPont Nonwovens. "Every day the average American spends 100 minutes in a car going to work, school or running errands. With DuPont Premium Interior Air Filters, drivers and their families can now spend that time breathing cleaner air."
The air inside the vehicle may contain more particles than the outside air because it draws in vehicle exhaust, fine road dust, pollutants, allergens, and other harmful airborne particles through the fresh air vent. Approximately 40% of new cars built in the U.S. today are equipped with interior air filters, while more than 70% of cars made in Europe and Asia now include such filters, sometimes referred to as cabin air filters. Similar to furnace or air conditioning system filters for the home, in-car air filters need to be changed regularly to be most effective.
