Q8: What is that UV light used inside the handheld UV Steriliser?
Answer: It is called Ultraviolet (UV C) light. A common one is UV B, which is widely used at tanning salon sun bedding. UV C has higher frequency of the UV light that can kill germs. It is part of the ultraviolet light spectrum.

Q9: Is UV C harmful?
Answer: Only prolonged exposure (ie. 8 or more hours) to UV C light will be harmful for human.

Q10 : How UV C kills germs?
Answer: 1)UV C light is highly effective at penetrating thin-walled germs like viruses and bacteria. The light alters the genetic structure of the germ and they die.
2)UV C light is not visible to the naked eye due to its location on the electromagnetic spectrum. But just because it cannot be seen does not mean it will not eliminate germs, bacteria, viruses and mould. Thanks to its germicidal wavelength (AKA frequency), UV C is ideally located in the spectrum that best inactivates microorganisms and viral air contaminants. When a virus or microorganism comes in contact with UV C its nucleus is penetrated, and its DNA is irreparably damaged, which results in death or the inability to reproduce, as well as the spread of unwanted germs! By applying UV C light we are able to do more than just put up a blockade we are able to terminate the source of the problem.

Q11: Does UV C light damage anything tangible?
Answer: No, it does not damage any material and it does not leave any chemical residue after scan.

Q12: Is UV C the latest invention?
Answer: No, in fact it has been used for over 100 years. Scientists applied it to kill germs on surfaces, in the air and in the water since 1930s. Now the advanced technology has emerged this useful source into this handheld UV steriliser.

Q13: Why does the air in my office still contains germs even if the air con is on?
Answer: The warmth and moisture found in the HVAC (Heating, Ventilation and Air Conditioning) systems of office buildings make the perfect breeding ground for airborne moulds, microorganisms and bacteria. These HVAC systems also provide an ideal way to circulate viruses and germs around an entire office building or home in a relatively short time
