Abstract: The invention relates to a comfort management system (1), in particular for a motor vehicle, said system being designed to diffuse, into a passenger compartment, a volatile substance designed to neutralize or attenuate an existing olfactory perception that a person could have in this passenger compartment.

Abstract: An antimicrobial purification device for ventilation, heating and/or air conditioning systems diffuses a volatile purification agent. The antimicrobial purification device includes an air filter (1) having a frame (2) holding a filtering agent (3). The filter (1) comprises at least one means for integrating substrate (5) holding the purification agent, consisting of a housing (4) holding the substrate (5) positioned in the frame (2) of the filter (1) or in a container mounted on this frame (2). A cap (6) sealing the housing (4) is fitted with a pin (18) to pierce a protective cover (19) in order to diffuse the purification agent as required.

Abstract: This invention relates to an air treatment device using a volatile treating agent contained inside of a permeable container (1) and a cap (4) closing the container (1). The cap (4) comprises a reservoir (12) containing the active agent.
