Method of making a gas phase permeable filter

摘要

Described is a gas phase permeable filter and method for making same comprising the steps: 1. providing a gas phase permeable substrate having opposite surfaces; 2. applying an adhesive to one or both of the surfaces of the substrate; 3. applying particulate gas phase odor-removing means to the adhesive coated surface or surfaces of the substrate; 4. drying the adhesive; and 5. assembling the substrate in a desired filter configuration wherein the outer surface of the filter is a surface of the substrate free of particulate gas phase odor-removing means and the inner surface of the filter is a surface of the substrate coated with the particulate gas phase odor-removing means adhesively secured thereto.
