ABSTRACT:
A filtration device having a housing which may be attached to and supported by the temple of a set of spectacles worn by a wearer. The filtration device is operable to filter air inhaled through the nostril of the wearer, and comprises a generally elongated housing having a length about equal to or less than the length of the temple of the spectacles, the housing also having at least one dirty air inlet opening and a clean air outlet opening at a spaced position therefrom. A filter element is received within the housing and is operable to filter air moving therethrough. Attachment means for selectively attaching and detaching the housing to the temple of a pair of spectacles are also provided, as are conduit means extending between the outlet opening of the housing and at least one nostril of the wearer so that the air inhaled by the wearer through the nostril passes through the housing. In a preferred embodiment, two filtration housings are provided and each may be attached to a separate spectacle temple, and the conduit means include a nose plug element having two nasal plugs, each of which is connected to a clean air outlet opening of a respective filtration device via flexible tubing. In other preferred embodiments, the filtration device also includes one-way valves to restrict the direction of airflow through the housings, and/or one-way valves operable to exhaust exhaled gases.
