An apparatus having a transducer configured to be modulated and transduce a liquid and form a simulated flame. The transducer may be piezoelectric transducer driven by a modulated drive signal that has varying power levels such that a liquid transduces to a mist, and also such that the transducer controls and shapes the mist to create a vapor plume. The plume is illuminated by a colored light source generating the simulated flame. A wick or a nozzle may present the liquid to the transducer. The wick may have different shapes i.e. helical, tiered, and include intertwined or braided fiber optic cables of varying colors, or LED lights/tubes. The transducer may have multiple openings, perforations, notches, and/or impressions to shape the plume and creating the effect of a dancing flame.

A humidifier for treating humidified air with germicidal light is provided. The humidifier includes a water reservoir, an atomizer to atomize a supply of water, and an ultraviolet light source to expose the atomized water to germicidal light. The ultraviolet light source extends vertically within a cylindrical channel to irradiate the atomized water dissipating upwardly from the atomizer. The water reservoir can include a carbon filter and a hardness-removing module for removing containments and metal oxides from the water supply. A control panel indicates the remaining useful life of the ultraviolet light source, the carbon filter and the hardness-removing module based on historical humidifier usage and water quality levels.
