Abstract: A humidifier for use in humidors includes a fill chamber, an emission chamber having at least one absorbent body therein, at least one opening in the top of the emission chamber for diffusing water vapor therethrough, and an adjustment apparatus for adjusting and controlling the amount of water vapor entering the humidor through the opening. Absorbent bodies are preferably separated by at least one channel. The channel extends along the lengths of the absorbent bodies to increase the rate at which the absorbent bodies absorb water. The channel separates the absorbent bodies into separate elements. The humidifier comprises a housing defining a receptacle having an internal void volume for receiving material. The volume of the absorbent bodies, in combination, preferably comprises from about 35% to about 70%, and most preferably from about 40% to about 50% of the internal void volume of the receptacle.
