An emanator (24, 60) for a volatile material comprises an elongate element having a first plurality of fibres (12, 68) distributed along its length and extending therefrom or substantially perpendicular thereto. The emanator further comprises a fluid pathway for the conveyance of volatile material along the emanator. The pathway comprises one or more second fibres (14, 64) substantially extending in a direction along the length of the element. A system (22, 72) for releasing a volatile material into a room comprises at least one such emanator, a fluid reservoir (26, 74) for a volatile material and a fluid delivery system (28, 76) for delivering fluid from the reservoir to the emanator.
