Ultraviolet (UV) light is an effective method of instantaneously killing germs, employed by hospitals and laboratories. When water is exposed to UV light, bacterial contamination and bacterial growth are virtually eliminated before the vaporization (boiling) process even begins. So the warm mist released into the air you breathe is 99.999% free of bacteria and molds that can aggravate symptoms of colds, allergies and other respiratory conditions.
You will find a tiny ball-like object floating inside the bulb. This part is used to ignite the bulb, and is not a defect of any kind.
