ABSTRACT:
A device is disclosed which attaches to the nose and filters the air a person breathes through the nostrils of the nose. The filter element of the device covers the nostrils and base of the nose. Thus, the remainder of the face is uncovered. The device includes the filter element and an adhesive strip which includes two substantially triangular portions designed to adhere to the sides of the nose and hold the filter in place. The adhesive strip is such that it securely holds the filter over the nostrils when the adhesive strip is properly placed on the sides of the nose. The filter element can be constructed of various materials. For example, cotton, wool, polyester, or carbon. The filter element can include specially designed inserts which are dome shaped or ellipsoidal shaped and which fit in or against the nostrils. The filter element can filter out unwanted gases, solid particles, and/or other matter.
