US Patent 11779781 Face mask with a neck hanger

A face mask uses a neck hanger to facilitate the flow of filtered fresh air inside the face mask for inhaling. The neck hanger is a lightweight tube that has a U shape and hangs from the neck of a user. The neck hanger houses a fan with a filter at either side, and a battery with a controller circuit. Two flexible pipes connect the face mask to the neck hanger from either side. The neck hanger sucks the air from the environment using a fan and filters it before being blown into the face mask through a flexible pipe. The face mask's contaminated interior air through another flexible pipe is sucked be another fan and filtered by a filter before being released into the environment.
