Poor quality air makes you tired, irritates your eyes and respiratory tract. Cabin air filters from MANN-FILTER ensure improved comfort and fresh air in your car, as they almost completely free the air entering the vehicle of dust, pollen, soot and other pollutants: precisely those substances which are causing health problems for more and more people, especially asthmatics and those with allergies. Like all filters, however, MANN-FILTER cabin air filters also have to be changed regularly. As a general rule, they should be serviced at one-year intervals or after every 15,000 km travelled. Misty windows, a stuffy cabin and a malfunctioning air conditioning system are also sure signs that replacement is necessary. Next time you are changing your cabin air filter, play it safe and choose a patented high-tech filter from MANN-FILTER. Our products are a perfect fit and of verified original equipment quality. Detailed installation instructions mean that assembly is quick and easy.
