Abstract
An evaporative humidifier includes a base having a portion defining a reservoir for holding a quantity of water. A housing is mounted on the base over the reservoir, the housing having an air inlet and an air outlet. A cylindrically shaped wick filter with a permeable support is seated in the reservoir and extends up into the housing. The cylindrically shaped wick with permeable support filter has an open top end and a sidewall. A color change indicator strip is provided on the inner portion of the sidewall. The color change indicator strip provides a signal when the filter requires changing due to the extent of use and immersion of the filter in water. A fan is mounted inside the housing for drawing air into the housing through the air inlet, then into the center of the cylindrically shaped wick filter through the open top end, then out through the sidewall of the cylindrically shaped wick filter with a permeable support and then out of the housing through the air outlet. A heater is also mounted inside the housing for heating the air drawn into the housing prior to passage through the cylindrically shaped wick filter with a permeable support.
