The invention relates to a support which can hold filters intended to collect the dirt due to the suction of mechanical air extraction vents. This support consists of a rigid base (1) which is self-adhesive on its rear surface, the base being pierced with a round hole (2). On its front surface we will find, on its lateral edges and its bottom edge, guide rails (3) which are used to hold the filter in place, a filter which will have the shape of the rigid base. This support can be fitted on all the types of mechanical extraction vents existing on the international market. <IMAGE>
