Breathe Again masks using patented Agion Technology that inactivates 99.99% of viruses within five minutes.There are three layers in the mask.
The first layer repels water, essential to prevent the droplets from someone coughing or sneezing from entering the mask. The second layer has gold and silver nanoparticles that act as an antiviral and antibacterial. The third layer prevents your own bacteria from escaping and infecting others.
There is no valve in the mask, as a valve allows the bacteria or virus from escaping and infecting others.
