ABSTRACT:
A filtering apparatus may comprise a base material folded in a folded state. A filter may be attached to the base material. In addition, the filtering apparatus may comprise a perforation. The perforation may be configured to define a portion of the base material configured to be removed from the base material. The base material may be configured to be transformable to an unfolded state when the portion of the base material is removed along the perforation. An adhesive may be attached to the base material. The adhesive may be configured to adhere the filtering apparatus around at least one orifice of a subject when the base material is in the unfolded state. In addition, the filter may be doped with medication or other substances depending upon an intended application. The filtering apparatus may also contain a tactile area to assist the subject in using the filtering apparatus.
