摘要： A personal air filter device with an air filter assembly retained in the air filter holding member is disclosed. An ear support member is attached to the air filter holding member and can be hung over the ear of the user to support the air filter holding member. Alternatively, a clip member attached to the air filter holding member can be utilized to attach the device to the user's clothing or accessories. An air tube assembly extends from the air filter holding member to the mouthpiece for the purpose of breathing filtered air flowing through the air filter assembly. An air intake check valve situated near the end of the air tube attached to a mouthpiece retaining member and an air outflow check valve situated near the outer surface of the mouthpiece retaining member to ensure exhaled air is directed out of the device and is not reinhaled.
