Abstract
A humidifier includes a housing with a substantially open top portion. Water can be added to the humidifier by pouring the water into a water reservoir through an open top. The water is pumped from the water reservoir to an upper portion of the humidifier where it is dispersed into the environment by a flow of air. The humidifier may include both an ultrasonic nebulizer and a heater to provide a warm mix of cool mist and hot vapor. Alternatively, a warm mist can be provided by dispersed water from an ultrasonic nebulizer in combination with warm air. The humidifier may also solely provide a cool mist from an ultrasonic element, or the water can be dispersed using a wicking filter.
