ABSTRACT:
An improved filter construction for odor adsorption adapted to fit into a frame provided with front and rear support faces. The filter media consists of one or more sheets of non-woven material impregnated with activated carbon particles. Each sheet is provided with a plurality of slit and expanded openings to permit gaseous flow through said sheet. The sheet material comprises a combination of cellulose and synthetic fibers in a weight percentage range of between at least 30 to 50 percent of cellulose fibers and 1 to 10 percent of synthetic fibers wherin the combination of the two fibers represent at least 40 percent of the total composition of the sheet. The activated carbon content is between 35 to 50 percent of the total composition by weight. A latex binder material and a wet strength resin are included for fabrication of the sheet and to reduce dusting of the charcoal. A flame retardant material may be included to the composition of the sheet in an amount sufficient to meet fire codes standard as required.
