Hand Dryer: What will the UV light in a hand dryer do?

There are UV lights added in certain hand dryers to safely help kill virus and bacteria from within the dryer over a prolonged period of time. They help keep the insides of the dryers or HEPA filters clean. This is not to be confused with a blue light that may be shone on the hands during the drying time. This is purely a light to guide the user to the airflow to aid drying efficiency and contains no UV properties.
