Inventors around the world are coming up with other options to the face mask- helmets.
Inventor Yezin Al-Qaysi has been riding the Toronto subway for the past two months wearing a huge black "mad helmet".
The hazmat (hazardous materials) helmet completely encloses his head and upper torso, and has a visor that extends all the way down to his chest.
On the back is a battery-powered fan and filter respirator system that purifies air that is sucked in, and pushes "stale" air out.
Yezin is one of a number of designers and entrepreneurs around the world who have rushed to release hazmat, or PAPR (powered air purifying respirator), helmets aimed at people looking for more protection against Covid than just wearing a face mask.
His is called the BioVYZR, and the battery is said to last for up to 12 hours. His sales are in the "tens of thousands" mark.
US Navy veteran Chris Ehlinger also created a helmet with his company, Valhalla Medical Design based in Austin, Texas. He launched a product called NE-1, which looks similar to a motorcycle helmet. It has a powered air filtration system, internal and external microphones and speakers. It even has Bluetooth audio built in.
There are many more and it looks like this could be the way of the future.
