L'unité de génération de particules chargées (4) et le capteur de particules chargées (5) sont agencés côte à côte dans une direction croisant la direction de l'écoulement d'air de sorte que l'électrode de détection (51) du capteur de particules chargées (5) et l'électrode de charge positive (42) ainsi que l'électrode de charge négative (41) de l'unité de génération de particules chargées (4) ne soient pas en face les unes des autres.
