A humidifier pad assembly for a humidifier that is configured for adding humidity to an air stream of an HVAC system of a building or other structure. The humidifier pad assembly may include a frame for holding a replaceable humidifier pad within the housing of the humidifier. The frame may be structured to hold the replaceable humidifier pad within the housing such that a back major surface of the replaceable humidifier pad generally faces the back side of the housing, and a front opposing major surface of the humidifier pad generally faces the front side of the housing. The frame may further be structured to permit removal and replacement of the replaceable humidifier pad through the front side of the frame. In some cases, the housing may be configured such that the frame (and the replaceable humidifier pad) may be slid out of apertures in the right side and/or left side of the housing. In some instances, the humidifier may include a drain funnel structured to collect water from substantially the entire bottom side of the frame and direct the water to a water drain. The drain funnel may be structured to allow the frame to be slidably moved (e.g. in the left and/or right direction) relative to the drain funnel and removed from the housing through at least one of the left side or the right side of the housing. In some cases, a water distributor is releasably attachable to the frame along a top side of the frame.
