The nose filter includes a first nostril unit and a second nostril unit which anatomically engage the nostrils of the user such that one unit extends into each of the user's nostrils. Each nostril unit includes a holder which carries a filter member through which air is inhaled. The filter member is held in position by a filter plug member fabricated from a resilient material which extends into the nostril passageway and anatomically engages the septum and nostril wall. The nostril units are secured together at a spaced location by a securing device which biases each of the units against opposite walls of the nose septum such that the nose filter position is fixed. | |
