A diffuser device ( 1 ) for volatile substances comprises a motor unit ( 2 ) and a refill unit ( 3 ) which can be assembled with each other. The motor unit ( 2 ) comprises a fan ( 6 ) for sucking in air comprising a body ( 60 ) and an electric motor (M 1 ) which drives a plurality of blades ( 62 ) in rotation, electrical power supply means ( 4, 5 ) for the motor (M 1 ) and a structure ( 20, 21 ) to support the fan ( 6 ) and the power supply means ( 4, 5 ). The refill unit comprises a refill of volatile substances ( 9 ), air filtering means ( 90 ) and a support structure ( 30 ) for the refill ( 9 ) and the filtering means ( 90 ). The filtering means ( 90 ) are situated upstream of the fan ( 6 ) to filter all the air sucked in by the fan ( 6 ). A laminar air flow generated in the fan body ( 60 ) strikes the refill ( 90 ) to favour diffusion of the volatile substances.
