1. A personal air purifier for insertion in a user's nose comprising:
two semi-cylinders of porous foam filter media each having a base with a flat surface and a spherical shape on an end distal
from the flat surface and having a plurality of circumferentially spaced flattened surfaces intermediate the base and distal
end;
at least one thin flexible tab integrally molded with the semi-cylinders and extending therefrom;
a flexible lanyard attached to the tab for constraining the personal air purifier when not in place in the user's nose;
the semi-cylinders sized such that upon insertion in a nostril the distal, spherical shaped end of each semi-cylinder is located
inside the nasal vestibule and the base of each semi-cylinder is tucked in within the nostril just behind the ala, the tab
assisting in preventing overinsertion of the semi-cylinders in the user's nose.
