A system for diffusing a composition includes a base that defines a first opening and a second opening and which encloses a space, the space comprising at least a portion of a composition reservoir and a diffusing element. The composition reservoir may be associated with the first opening and configured to receive the composition at the first opening. The composition reservoir may also comprise a sloped wall associated with a diffusing element, the diffusing element configured to diffuse the composition at the second opening. The diffuser system may further comprise a salt formation.
