The Power of UV-C Light Technology

What is UV-C?
UV-C is part of the ultraviolet light spectrum that is filtered out by the earth’ s atmosphere. The “ C” stands for the particular frequency of UV light that kills germs.

Is UV-C harmful?
Prolonged exposure (ie eight or more hours) to UV-C light can cause eye irritations.

Is this new technology?
No. UV-C has been used for over 100 years in various applications to kill germs on surfaces, in the air and in the water. UV-C has been proven to kill up to 99.9% of germs. Many hospitals use UV-C to sanitize.

Why is my indoor air so dirty?
The warmth and moisture found in the HVAC (Heating, Ventilation and Air Conditioning) systems of households and office buildings make the perfect breeding ground for airborne molds, 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. It is no wonder that each year five to twenty percent of the entire U.S. population develops influenza. This is part of the reason why having a room air purifier is so important.

Thanks to emerging technology the power of UV-C has been harnessed and is now available for personal use. Recently there have been a number of applications of UV-C technology on products in the home sanitization market. Some of the most successful and effective uses of UV-C include: air sanitizers, handheld UV wands, toothbrush sanitizers, HEPA Air Purifiers and floor care, vacuum cleaners in particular.

How Does UV-C Work?

Why is UV-C so effective at destroying germs?
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.

UV-C light is not visible to the unaided eye due to its location on the electromagnetic spectrum. But just because it cannot be seen doesn’ t mean it can’ t put up one tough fight against germs, bacteria, viruses and mold. 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 destroy the source of the problem.

Location: Bathroom
The Culprit: Toilet

What Could Be Lurking There: Rotavirus (one of the most common causes of severe diarrhea among children)

Even if you aren’ t using a public restroom, just how clean do you think that toilet you’ re about to take a seat on is? It is a toilet afterall.


Location: Hotel Room
The Culprit:: Bedding

What Could Be Lurking There: Rhinovirus (the cause of one third of all colds, and estimated cause of 30-50% of the time from work by adults)

How many people do you think have slept in that bed before you? And what viruses, germs and bacteria have they left behind for you to share the bed with?


Location: Kitchen
The Culprit: Cutting Board and Utensils

What Could Be Lurking There: Rhinovirus (the cause of one third of all colds, and estimated cause of 30-50% of the time from work by adults)

Salmonella* (Food preparation areas in your kitchen can provide the ideal breeding ground for this gastrointestinal infection-causing bacteria)

The perfect breeding ground for E.coli and Salmonella. Don’ t let that delicious meal you just prepared be your ticket to an awful evening in the bathroom!
