UV-30 Sterlizer Night Light
 
How effective is UV sterilization?
 
UV light has been used for sterilization and disinfection as early as the mid-20th century. With advancements in technology, and specifically in the UV bulbs themselves, its reliable long lifespan (thousands-of-hours) and smaller size (e.g. UV LED vs traditional UV bulbs) has broadened the field for where it can be used. You can find it being used to disinfect: water, air, fruits, vegetables, surgical utensils, materials, toys, and a variety of surfaces and rooms.
 
Is UV sterilization effective for viruses and bacteria?
The short answer is yes, and even more organisms. It works by breaking down certain chemical bonds and scrambling the structure of DNA, RNA, and proteins, causing a microorganism to be unable to multiply.
