ABSTRACT:
A new and improved humidifier wick and its method of manufacture are disclosed. The humidifier wick is made from a cellulose foam material that is compressed to a predetermined thickness in a dry condition. A series of air flow openings are formed in such material. As a result, the wick is capable of being expanded to a substantially increased thickness when wet in order to allow air to be drawn through the air flow openings for conveying moisturized air by a power driven fan blade from a humidifier into the atmosphere of a room. The air-flow openings are pre-configured in the humidifier wick, when in its dry condition, in order to allow air to pass into and beyond the air flow openings of the wick when it is wet and expanded. The wick may be used by itself or together with a number of similarly constructed wick elements. The method of forming air flow openings in an endless web of cellulose foam material when in a compressed and dried condition; and cutting the endless web of cellulose foam material into discrete individual humidifier wick segments.
