RE:RE:Curious as to how long it took to certify
I would think that Zen is neck and neck with these guys as far as testing goes from what i have read. I am glad that the skin irritation tests have passed as that was my biggest fear. The fact that well over 99% of pathogens are eliminated means that this will become the standard in mask production. For example, graphene is very inexpensive on a per mask basis. Every producer can and likely will incorporated it into their production line.
Also, the mask's ability to kill bacteria/virus on contact means that hospitals will jump on the technology. My daughter is a nurse (non-emerg) and she is required to wear the same PPE for one week before changing. The comfort in knowing that touching and removing the mask multiple times without the fear of infection is groundbreaking.
