A typical embodiment of the invention reduces the load on an air conditioner and provides more efficient evaporative cooling, humidification and filtering. Improved cooling and humidification is the result of an ultrasonic fog generator which reduces liquid droplet size to about ten microns for flash evaporation. A silica-containing filter, moreover, has an affinity for mechanically unfilterable residual calcium-containing particulate matter that is entrained in the humidified air, in order to extract this matter from the treated air.

Apparatus for humidifying and evaporatively cooling the air in a room, comprising: an enclosure having an inlet port for receiving room air; a fogging chamber in said enclosure, communicating with said input port; an outlet port communicating with said fogging chamber for returning air to the room; a circulating fan for creating a draft of air through said inlet port, fogging chamber, and outlet port; an ultrasonic fogging device disposed in said fogging chamber, the fogging device including: a nozzle having an elongated open-ended passageway formed therein for receiving a supply of compressed air and an opening which communicates with said passageway through which a supply of water can enter the passageway; a parabolic resonator cup spaced from and facing the opening of the nozzle passageway; manually adjustable mounting means for said resonator cup for manually adjusting the spacing between said resonator cup and the opening of the nozzle passageway; said fogging device being oriented in said fogging chamber such that said spacing is transverse the direction of air circulation through said chamber; and a filter disposed in said enclosure in the path of the humidified and cooled air from said fogging chamber, said filter containing silica to combine with calcium-containing residue in the humidified air.
