A vehicle cabin filter assembly 10 has a filter module 30 and a downstream further filter module 20. The filter modules both comprise one or more filter elements 32, 22, with the filter elements of the filter module pleated in a first direction and including a gas filter element (37, fig 6) such as granules of adsorbent, whilst the filter elements of the further filter module are pleated in a second direction and include a particulate filter 45. The first and second pleat directions are nonparallel, and may be perpendicular. The filter elements of the further filter module may be at a different pleat pitch (P2, P3, fig 6) to the filter elements of the filter module. The assembly may also include an additional filter module 40 that features an additional particulate filter 42, the additional filter module being located upstream of the filter module. A vehicle (1, fig 1) using the filter assembly is also claimed.
