The new UV-C room sterilizer is perfect for sanitizing surfaces in larger rooms in your home or office! Easy to use, simply plug into a standard outlet and use the onboard timer or remote control to activate then exit the area. The device will turn on and sanitize for 15 minutes then automatically shut down- leaving disinfected surfaces while eliminating odors and viruses. Integrated sensors shut down the lamp if anyone enters the room, including pets. The quality of the air we breathe and the cleanness of surfaces we contact are important factors that impact our overall health and well-being. Today, more than ever, individuals are at risk of contracting and spreading bacteria and viruses. This UV-C Room Sterilization Lamp is tested and proven to properly disinfect and inactivate 99.99% of bacteria and viruses. Even workplaces such as offices, waiting rooms, and common areas can benefit from the same UV-C technology that has been used in hospitals and labs for cleaning and disinfecting rooms for years. Instructions:To get started, simply plug into a wall outlet. Turn the device on by pressing the "on/off" switch then select the duration you want - 15 minutes for a 100 square foot area, 30 minutes for a 200 square foot area and 60 minutes for a 400 square foot area. Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet A (UVA), ultraviolet BC (UVB), or ultraviolet C (UVC) light to kill or inactivate microorganisms by destroying nucleic acids which, in turn, disrupts their DNA, rendering them inactive by leaving these cells unable to perform vital cellular functions. UVGI is already used in a variety of applications, such as food, air, and water purification.
