The VendiGlobe Advantage

A Far UV 222nm disinfection lamp is a type of ultraviolet (UV) light that emits light at a wavelength of 222 nanometers (nm), often referred to as UVC light. This wavelength is shorter than the traditional UVC wavelength (around 254nm) used for disinfection purposes but is considered safer for humans while still being effective at killing bacteria, viruses, and other pathogens.

Here are some key features of Far UV 222nm disinfection lamps:

Wavelength (222nm): The 222nm wavelength is specifically effective in breaking down the DNA or RNA of microorganisms, rendering them incapable of replication and causing them to die.
Safety for Humans: Unlike conventional UVC light (typically in the 254nm range), Far UV 222nm is considered to be safe for human exposure because it cannot penetrate the outer layer of the skin or the eyes, thus avoiding harm to tissues. This makes it suitable for use in occupied spaces for continuous disinfection.
Applications: These lamps are used in various environments like hospitals, schools, offices, public transportation, and even home settings to continuously disinfect air, surfaces, and objects without posing a health risk to people.
Effectiveness: Far UV 222nm lamps are proven to inactivate a wide range of pathogens, including bacteria, viruses, and fungi, without the need for chemical disinfectants.

This technology is gaining popularity, especially in the context of the COVID-19 pandemic, for its ability to provide a continuous, chemical-free disinfection method in occupied spaces.

Everything You Need to Know About Far UV Disinfection Light System

Germicidal UV lights are an up-and-coming technology that will revolutionize the fight against the COVID pandemic.
UV Lights Have Been Used for Medical Disinfection Since the Mid 1900s
UV lights have been around for nearly 80 years now, and their use has only grown over the years. The main reason for this is how adequate UV light is at eliminating airborne and surface pathogens

Various Wavelengths of UV Light Are Harmful

We can’t deny the fact that some wavelengths of UV light can be harmful. Anything over 230 nm is harmful to a person. Some after-effects of excessive UV light exposure at this range can cause cancer, drying of skin and liver spots. This is the norm in the usual medical setting because of how well UV light can neutralize pathogens at this range.

While Other Wavelengths are Completely Harmless To Humans

We’ve mentioned that some wavelengths of UV light are harmful to you. However, that isn’t the case for all wavelengths of UV light. UV lights under the 230 nm we’ve mentioned are safe for humans. Anything below that wavelength cannot penetrate the upper layer of your skin. The same can’t be said for bacteria, however, as there is a sweet spot where bacteria will die, but remain harmless to people. Perfect for use in a business or home setting.

New Technology Has Allowed the Safe and Effective Use of Germicidal UV Lights in Businesses and Households

We mentioned that there is a sweet spot where UV light can destroy pathogens while still being safe for people. This range lies between 207 nm and 230 nm. To be specific, this wavelength range is more commonly called Far UV. Far UV is now incorporated in many UV disinfectant tools like VendiGlobe’s own Vendi222™ FUV light disinfection systems, which allows businesses to continue functioning even in the midst of the pandemic, and households to feel safer.

Final Thoughts

Germicidal 222nm FUV lights are an excellent technology to have around, as they can passively cleanse the air and surfaces around it. And rest assured that this technology is a safe option among the other options available in the market.
