La cartouche de filtre à air (15) comprend une première enveloppe ou enceinte (20, 120) de filtrage d'air sensiblement en forme de sac ou de poche, dont les dimensions sont conçues pour en permettre l'insertion ou l'enfichage dans l'orifice de ventilation, cette enveloppe ou enceinte étant configurée pour retenir la peluche et/ou les fibres en suspension dans le courant d'air (f). La cartouche de filtre à air (15) comprend également une deuxième enveloppe ou enceinte (20, 120) de filtrage d'air, sensiblement en forme de sac ou de poche (30, 130), qui est montée ou enfoncée en creux à l'intérieur de la première enveloppe ou enceinte (20, 120) de filtrage d'air de façon à être traversée sensiblement par le même courant d'air (f) que celui qui traverse la première enveloppe ou enceinte (20, 120) de filtrage d'air. En outre, la cartouche de filtre à air (15), qui est configurée de façon retenir la peluche et/ou les fibres en suspension à l'intérieur du courant d'air (f), est mécaniquement couplée coulissante à la première enveloppe ou enceinte (20, 120) de filtrage d'air.
