When UVC bulbs are used unconsciously and unwittingly, they can produce large amounts of ozone. Ozone is dangerous for human health and the environment The safe value determined by the US Environmental Protection Agency (EPA) is 0.05ppm ( number of parts per million) ozone. UVC Rays can harm humans, organisms and the environment when applied directly. All particles (dust and microorganisms) which travel in the air can cause severe problems for the human body. Bacteria that are beneficial for human health enter the body through our food, not by air.
Fresh Air is gaining as much importance as hand washing, clean water etc. It cannot be neglected in Total Hygiene Concepts. Viruses have been proven to be transported by air.
