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 and a spherical shaped surface at a distal end with flattened surfaces circumferentially spaced about the semi-cylinder for enhanced fit within the nostril. A lanyard is attached to tabs extending from the semi-cylinders to secure the personal air purifier when not inserted in the nostrils.
