UV-C light is safe to use, with restrictions. It is not recommended to be in the room when using a UV-C disinfection device. Most of the dead skin on on our bodies will absorb the UV-C, but the complication for this could be a rash. If you look at the UV-C device while it is running, a short time is okay but the the complication here would be conjunctivitis.
Smart UV makes its UV-C devices with safety features and protective eyewear to ensure your safety.
The Apollo uses an ozone-free bulb and produces no ozone. There is a 10 second delay to start The Apollo, and uses 5-meter motion detection sensors for pets and unexpected visitors. The Apollo also comes with UV-C protective glasses and a remote, if you wish to use the unit from a distance.
Smart UV uses a 30 second delay to start the unit. Smart UV produces a small amount of ozone, for double sanitation, and it is best to wait 30-45 minutes after use to allow the odor to dissipate.
The Helios UV-C wand uses LED UV-C and this is different than the lamps. UV-C when emitted from an LED will be direct and funneled and concentrated. This is why we can use low level wattage, and why Helios is safe to hold for surface disinfection.
Smart UV's UV-C disinfection devices should only be used by adults, as which all other disinfection agents. They are chemical-free, and they are still used for sanitation purposes and best used in the hands of an adult.
