ABSTRACT:
A disposable nose filter to be inserted in a nostril, including a flexible housing, a filtering component, a flange and an adhesive component. The nose filter is adapted to be easily inserted and removed from the nostril. When positioned in the nasal passage of a nostril the nose filter becomes fixedly attached inside the nostril through the adhesive component, until removal. The flange forms a seal with the lower exterior portion of the nostril, thus, forcing air through the filter and preventing air from passing between the housing and the inner walls of the nostril.
