ABSTRACT:
An attachment for an air filter enabling it to be worn at a convenient location on a person's clothing. The attachment has a fitting for attachment to the filter which provides a passageway for the filtered air, a hose having a main air passage extending up from the fitting to a breathing device and a branch passage between the breathing device and ambient air, and a check valve arrangement which closes the branch passage when the user is drawing in filtered air and opens the branch passage when the user expels air through the breathing device. The fitting has a safety pin for attaching it and the air filter to the user's clothing.
