Abstract
Apparatuses, systems, methods, and computer program products are disclosed for a diffuser and interchangeable cover. A complete diffuser includes a diffuser element that disperses a liquid into air within a diffuser chamber of the complete diffuser. A complete diffuser includes a lid shaped to at least partially enclose an upper opening of a diffuser chamber. A cover is removably couplable to a complete diffuser over a diffuser lid so that a dispersed liquid passes through one or more openings in the cover. A cover includes one or more decorative features having a different external shape than a complete diffuser that receives the cover.
