A room that has been disinfected with UVC can have some lingering odors; these odors will dissipate once the room is aired out. This odor is the result of the breakdown of dust during disinfection. 80% of dust in a room consists of dead human skin and hair cells. As these cells break down, they release chemicals which cause these odors.
So will it smell like a crematorium? Nice!! Heading to Four Seasons Total Landscaping right now!!
