UV sterilizers emit a small amount of ozone after each use, which is what causes the smell. If a baby is exposed to ozone in the air, it is not harmful. When UV-C light hits metals, such as aluminum, it has enough energy to eject electrons from them. The actual level of ozone obtained after UV disinfection is negligible and, therefore, it is concluded that the volatile organic compounds (VOCs) responsible for the residual odor after UV disinfection do not pose a danger to human health. As an expert in the field of air quality and HVAC systems, I can confidently say that UV-C lights are a safe and effective way to improve air quality.
The use of these lights can help reduce the presence of bacteria, viruses, and other contaminants in the air. Additionally, they can help reduce odors caused by mold and mildew. I have installed short-wave ultraviolet (UV-C) lights in my heating, ventilation and air conditioning (HVAC) unit, exactly in the coil box. In short, the use of these lights is not dangerous within the system and any metallic odor you perceive may be the result of the production of ozone gas by UV-C lights. The ozone produced by UV-C lights is not harmful to humans or animals in small amounts. However, it can be irritating to those with respiratory issues or allergies.
It is important to ensure that your HVAC system is properly ventilated to reduce any potential odors. In conclusion, UV-C lights are a safe and effective way to improve air quality and reduce odors caused by mold and mildew. The ozone produced by these lights is not harmful in small amounts and can be easily managed with proper ventilation.
