ABSTRACT:
An evaporative element or cartridge especially useful in humidifiers comprises a plurality of stacked slit and expanded wicking paper layers, and means for supporting the wicking paper. The supporting means may comprise a layer of slit and expanded metal sandwiched in between the stacked wicking paper layers. The stacked wicking paper and metal layers are held together with an adhesive. Alternatively, the supporting means may comprise a rigid frame on the side edges of the stacked wicking paper layers, the frame having prongs engaging the wicking paper layers. Each layer of stacked wicking paper is staggered with respect to adjoining layers. The wicking paper has superior capillary rise of 79 to 112 mm/min.
