Virus protection Mask A. Maximized virus inactivation annihilates viruses on the mask surface within minutes- 99.99% inactivation of VIRUS BUSTER CAZ material proved by Colorado State Univ.(USA) and Nara Medical Univ.(Japan) labs. B. Maximized filtration efficiency blocks out infected droplets-VIRUS BUSTER masks have 85~95% filtration efficiency performance.- The filtration efficiency of VIRUS BUSTER masks last constantly for weeks. C. Minimized pressure drop enables easy breathing D. Eco friendly & Economic mask must be reusable & washable -Prerequisites to the reusable mask are Self sanitization and long lasting filtration. The reason why disposable masks can not be reused is not only because the filter efficiency is drastically deteriorated, but above all, the virus on the mask surface survives for weeks to infect the wearer . -The virus buster mask self sanitize the Covid 19 virus and all the other microbes to provide safe and odorless reuse.
