Abstract
Apparatuses, systems, methods, and computer program products are disclosed for a diffuser and one or more removable diffuser covers. A removable diffuser cover comprises one or more decorative features. A cavity in a diffuser cover is shaped to receive a complete diffuser. A complete diffuser comprises a diffuser element that disperses a liquid into air within a diffuser chamber and a lid shaped to at least partially enclose an upper opening of the diffuser chamber. One or more openings are positioned to receive a dispersed liquid from a lid of a complete diffuser within a cavity and to allow the dispersed liquid to pass to an exterior of a removable diffuser cover.
