My Artemis 222 uses filtered krypton-chlorine (Kr-Cl) excimer lamp that produces essentially monoenergetic UV light at 222 nm and established that a wavelength window exist in the far uvc region (from 200–222 nm) that inactivates bacteria efficiently，but unlike conventional germicidal UV lamps (254 nm), which is not cytotoxic or mutagenic to mammalian cells.
This lamp can be mounted on a tripod for use by facility management companies to move around the office, or it can be mounted on walls or poles for a permanent installation.
