Nose filter
First Claim
1. A nose filter for filtering air breathed through the nostrils, said filter comprising:
- a first nostril unit for filtering air inhaled through one nostril of user'"'"'s nose and a further nostril unit for filtering air inhaled through the other nostril of the user'"'"'s nose, each of said units including a holder having a substantially cylindrical configuration with a bore therethrough, said holder defining a upper end portion and a lower end portion, said lower end portion defining an annular shoulder section such that the bore extending through the lower end portion of said holder has a reduced diameter, a filter member having a cross-sectional outline approximately equal to the cross-sectional outline of the holder bore in said upper portion, said filter member defining a perimeter which rests on the shoulder section of said lower end portion of said holder, a filter plug member having a generally cylindrical outline and defining a passageway therethrough said plug member having a lower end portion slidably mounted within said upper end portion of said holder, said filter member being held in said nostril unit between the lower end of said plug member and said annular shoulder, said plug member further including a body portion having a contoured, external wall for receiving a portion of the nose and an upper end portion, said upper end portion being flared outwardly to assist in holding said plug member within a nostril, andsecuring means for joining said first nostril unit with said further nostril unit at a preselected spaced location, said securing means serving to bias said first nostril unit towards said further nostril unit such that the septum of the nose is anatomically engaged by said plug member of said first nostril unit and said plug member of said further nostril unit whereby said filter is releasably mounted on the nose of a user.

Abstract
A nose filter for filtering air breathed through the nostrils is provided. 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.
