SAN JOSE, CA--North American sales of automotive aftermarket filters will increase by 30 percent during the next 6 years, from $1.3 billion in 2000 to $1.7 billion in 2007.

According to a report by Frost & Sullivan, automotive filter sales will increase because of the growing number of cars on the road and an increase in the average number of miles that people drive each year.

Sales of cabin air filters will be particularly strong. By 2005, 80 percent of new vehicles sold in North America will be equipped with such filters. "Because cabin air filters are expected to be replaced every 3 years, this market should see very strong growth," says Matthew Bickford, an analyst with Frost & Sullivan.
