The device surveils its surroundings, adjusting filtration power as necessary. As the diffuser is activated -- it breathes, collecting pollutants in the room.

The conical ceiling diffuser borrows formal language from that of a ceiling rose, a classical plaster ornament commonly fixed to ceilings above chandeliers, that serve as a way to conceal wiring. The new ceiling diffuser is put back into conversation with the ceiling rose by articulating a vernacular which is highly ornamental, with hollows and cavetto that collect dust and dirt from the air.
