The invention relates to a paper roll support for use as a room air freshener, in particular for toilet paper rolls, with an internal space and a longitudinal axis (14) extending horizontally in the operating state. It is proposed according to the invention that a movable membrane element (54) extending along the longitudinal axis of the paper roll support (10) be arranged in the internal space (50), said membrane element subdividing the internal space into two chambers (72, 74), wherein the membrane element (54) is arranged in such a way that it moves about the longitudinal axis of the paper roll support (10) in the operating state on rotation of the latter in such a way that the volumes of the chambers defined by the membrane element (54) vary inversely, and wherein the chambers (72, 74) optionally have closable connection openings (82) for air exchange with the surrounding environment. The invention additionally relates to a system consisting of a paper roll support and a paper roll mounted thereon, a paper roll holder and use of a paper roll support.
