Q: What are the differences between other Far UV-C lamps & Care222?

A:

We have worked with our global research partners to develop an optical band pass filter that prevents harmful UV rays from leaving the lamp. Ushio’s Care222® filtered Far UV-C technology (“Care222 Technology”) is protected under U.S. and non-U.S. patents covering apparatuses and methods for inactivating viruses or killing bacteria with combinations of a light source and an optical filter that block potentially harmful UV-C wavelengths. Inventions in these patents are credited to Dr. David Brenner, et al., and assigned to Columbia University. Ushio Inc. is the worldwide exclusive licensee of these patents
