Abstract
A vehicle cabin filter assembly comprising a filter module and a further filter module positioned downstream of the filter module. Each filter module comprises one or more filter elements. The filter elements of the filter module are pleated at a first pleat pitch and comprise a gas filter element. The filter elements of the further filter module are pleated at a second pleat pitch and comprise a particulate filter element. And the second pleat pitch is smaller than the first pleat pitch.
