A Japanese company has developed a UV lamp that it says can disinfect rooms even when there are people present. The lamp emits a UV wavelength of 220 nanometers.
At this wavelength, UV rays cannot infiltrate the surface of the skin nor the eyes to bring about cancer-causing genetic defects and other damage, according to Japan Today.
The company plans to sell the lamp to medical facilities first.
The lamp would be installed in ceilings. When it emits the UV light, it kills 99.7% of viruses and bacteria in the air and on surfaces of objects within 8 feet of the lamp. The application takes between 6 and 8 minutes. The device weighs 2.6 pounds and the company plans to sell them for around $2,800 each.
