Mechanism of action of VPE_TM

The inner headgear has an adjustable head strap, a fan that provides negative suction and a chamber. The fan runs on a 12V battery. When the fan runs it creates a negative pressure in the chamber above it. This negative pressure suctions the atmospheric air through the N95 mask situated above the chamber with the external protective visor. The clean air thus suctioned through the N95 mask and it will be blown towards the user.
