Abstract
A disposable nose filter to be inserted in a nostril, including a flexible housing, a filter component and a flutter valve. The nose filter is adapted to be easily inserted and removed from the nostril. The flutter valve 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.
