ABSTRACT:
A personal air purifier employs tapered reticulated foam semi-cylinders sized to be closely received within a user's nostrils through slight expansion of the nostril. The semi-cylinders include a flat base with flattened surfaces circumferentially spaced about the semi-cylinder for enhanced fit within the nostril. The flat base of the two semi-cylinders is connected by an integral flexible band with arcuate edges tangentially interfacing the bases which extends across the end of the septum of the user's nose to preclude over-insertion and aid in removal. Electrostatic charging of the dielectric foam further enhances performance of the personal air purifier.
