Air filter for the interior of motor vehicles
摘要:
An air filter includes a housing having an air inlet and an air outlet. A filter element is insertable into the housing. The filter element includes a filter medium folded in an accordion-like manner, as well as a surrounding seal for sealing off a pure-air area. The air inlet of the housing has the same cross-section as that of the filter element. Holders are arranged on the housing via film hinges. The holders operate to fix the filter element in an installed position in the housing.
