Abstract
The present invention is a family of portable humidifiers. Each of the portable humidifiers has a housing, a number of wick assemblies, and a fan. The housing has an air inlet, an air outlet and a reservoir for holding water. The number of wick assemblies are positioned within the housing to contact the water in the reservoir. The wick assemblies are arranged in parallel between the air inlet and the fan. The fan is provided within the housing for creating an airflow. The airflow enters the air inlet, passes through the wick assemblies for adding moisture to the airflow from the water in the reservoir, and exits through the air outlet. The number for at least one of the portable humidifiers is different from the number for another of the portable humidifiers. Preferably each of the portable humidifiers includes a wick frame seated within the reservoir for supporting the wick assemblies. Each of the wick assemblies preferably has a wick element and a button.
