This is a model to allow people to make their wearable HEPA that blows filtered air to their faces, in situations when wearing a respirator is impossible. It's not meant to be a substitute to respirators, but an added safety to the wearer, whether or not a respirator is worn.
The only shortcoming is the noise, and I suspect it's coming from the area between the ball bearing and the holder of the bearing. I include the Blender file, so anyone can modify it as they please.
