Abstract
A common wall mounted forced air duct register humidifier that has an easily replaced and maintained water bowl and includes a drum fan that has blades along its length to facilitate air movement to assure evaporation of the liquid placed in the bowl and an air deflection surface that partially deflects the air coming out of the forced air duct register into the water bowl to assure adequate evaporation.
