. For instance, AirGuard can be installed in the HVAC system of a shopping mall to disinfect airflows throughout retail shops, food courts, lobbies, bathrooms, and elevator systems. A typical mall with a 36ft atrium with a total area of 10,000ft 2could be purified at a virus reduction rate of 98% via AirGuard UV -Cdisinfection in 10 minutes. Moreover, O -RXrobots may autonomously patrol and disinfect mall corridors and pathway at a rate of up to 2,500 ____________ 2 https://ec.europa.eu/health/ph_risk/committees/04_sccp/docs/sccp_o_031b.pdf 106 square feet per hour. O -RXrobots may utilize its lift integration technology to maximize its coverage between multiple floors. For small, confined spaces or private spaces in the mall, such as bathrooms, employee only offices, or kitchens where the O -RXrobots may not be programmed to enter, TreX can instead be stationed as a portable disinfection unit. AirGuard — Air Disinfection Solution AirGuard is designed to clean and disinfect indoor airflow using our UV -CLED technology. AirGuard’s UV -CLEDs modules are integrated within the HVAC systems, such as air conditioning units and ventilation ducts. These modules are able to inactivate airborne viruses and bacteria through ultraviolet germicidal irradiation (“UVGI”), disinfecting the air circulated indoors as it flows through the HVAC system. The modules have been lab tested to achieve a 99.9% disinfection efficacy within an 8 foot range, while a typical industry HVAC duct is no longer than 2 feet in length. The AirGuard system is designed to be compact and easy to install in most HVAC systems, with minimal modification required. The system is further customizable with options for additional sensors to monitor temperature, airflow, and overall air quality. Each AirGuard module’s physical dimensions are as follows: height: 1.8 inches, width: 1.2 inches, length: 8.5 inches, weight 10.6 oz. O-RX — UV-C LED Disinfection AMR In response to the COVID -19pandemic, Otsaw pioneered the world’s first incorporation of UV -CLED technology within an AMR: the O -RX. This combination is a powerful tool to combat the spread of COVID -19and other pathogens. Leveraging on our highly scalable software and hardware platforms
