TM VIRUS BUSTER MediFiber Inc 1 About MediFiber MediFiber is a medical device company that specializes in medical equipment made from natural polymer fiber History - Fiber Technology Inc founded in 2011 • Manufacture and sales of hemostatic block for surgical care • Manufacture and sales of absorbent dressings for severe burns • R&D on an artificial skin platform using collagen fiber • R&D of anti-adhesive membrane using hyaluronic acid - Affiliate MediFiber set up in 2020 • Production of virus inactivation product VIRUS BUSTER using CAZ In the wake of COVID-19, MediFiber developed virus inactivation masks, external AC filters, and surface patch made from CAZ, a patented material that has virucidal properties 2.1 CAZ & Oligodynamic Action CAZ • CAZ is a copper ion bonded natural polymer fiber developed and produced by MediFiber, and is the only fiber material that has a strong ionic bonding with copper upto 50,000 ppm Oligodynamic Action • Copper has virucidal properties called the Oligodynamic Action where upon contact, the virus’ outer protein shell is destroyed and RNA break down into pieces, thus totally annihilating the virus Oligodynamic Action : A biocidal effect of metals, where even in low concentrations metal ions kill microorganisms by disrupting their metabolic activity Copper, gold, silver, platinum, aluminum, mercury, nickel, cobalt, zinc exhibit this property Silver has sterilizing properties, and copper exerts the strongest effect of killing viruses 2.2 Laboratory Testing for Effectiveness against COVID-19 Criteria for effectiveness against SARS-CoV-2 Criterion met by CAZ Was the testing done by a certified agency that specializes in virus testing/research with at least a Bio Safety Level ? Colorado State University, U.S : BSL-3 Nara Medical University, Japan : BSL-3 * Simultaneous testing was approved in both countries’ laboratories Did the test methods follow the international standard ISO 18184 Protocol ? ISO 18184-2019 applied Was testing done with SARS-CoV-2 , the virus that cause Covid-19? Tested with SARS-CoV-2 Was 99.99% (log4) inactivation (the required value for total annihilation of the virus) reached in a meaningful amount of time? 99.64% inactivation in 5min 99.999% inactivation in 30min *99.999% is acknowledged as Undetectable CAZ Products Masks PPE Qurantine gloves under development Qurantine suits under development Residential/commercial AC filters HVAC Transportation PSP Surface patches Wallpaper under development • PPE : Personal Protective Equipment • PSP : Public Space Protective Equipment 3.1 VIRUS BUSTER MASK What only Virus Buster Mask can offer : Prerequisites to fighting COVID-19 A Maximized virus inactivation annihilates viruses on the mask’s surface within minutes - 99.99% inactivation of VIRUS BUSTER’s 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 3.1 VIRUS BUSTER MASK Filter options for Reusable, Washable mask A Reusable Mask : MB (Hydrocharged) filter -
