Abstract: In heating or air conditioning equipment for the passenger compartment of a motor vehicle, the equipment being connected to the bulkhead on the passenger compartment side and covered by a dashboard provided with a glove compartment and having an air filter located on the air inlet side, it is proposed that, for easy insertion and removal of the air filter, the latter should be aligned at least approximately horizontally and located adjacent to the glove compartment insert. After the insert or a partial region of it has been removed or pivoted away, the air filter can be inserted and removed through the glove compartment opening.
