Abstract:
An improved nasal air filtration apparatus comprised of a flat, disk shaped baffle air filter inserted into each nostril, so that upon inspiration the air filter is closed from the inspiration air pressure, and upon exhalation the air filter is opened by the exhalation air pressure, allowing easier and more efficient breathing of filtered air through the nostrils.
