Airborne-mediated microbial diseases such as influenza and tuberculosis represent major public health challenges. A direct approach to prevent airborne transmission is the inactivation of airborne pathogens such as Coronavirus. The airborne antimicrobial potential of UVC ultraviolet light has long been established; however, its widespread use in public settings is limited because conventional UVC light sources are both carcinogenic and cataractogenic.

However, a breakthrough has proven that far-UVC light (207-222 nm) efficiently inactivates bacteria without harming exposed mammalian skin. https://faruv.lighting/

Due to its strong absorbance in biological materials, far-UVC light cannot penetrate even the outer (nonliving) layers of human skin or eye; however, bacteria and viruses are of micrometer or smaller dimensions, far-UVC can penetrate and inactivate them.

For the first time in history, people can now use far-UV to safely and efficiently inactivate airborne aerosolized viruses, with a very low dose of only 2 mJ/cm2 at 222-nm light; Far-UV was first proven to work by inactivating aerosolized H1N1 influenza virus.

Far-UVC light manufacturers and Far UV companies now have much greater flexibility in designing products with the compact, preassembled Far-UVC QuantaModule 222-nm Far-UVC Light for sale in 5 Watts, 15 Watts, and 20 Watts. Far-UVC light manufacturers create lights for cutting-edge AP-UVGI (Active Personnel Ultraviolet Germicidal Irradiation). and Far-UVC light cancer isn’t a concern because the filtered far-UVC wavelengths can’t reach the DNA of living human cells.

Excimer 222 nm Far-UVC Light Bulbs Require Band-Pass Filtering For AP-UVGI (Active Personnel Ultraviolet Germicidal Irradiation) Applications!

Filtered Far-UVC Excimer QuantaBulbs should always be used in combination with other measures, like wearing face masks, distancing, and washing hands, to limit virus transmission.

The most common way to manufacture Far–UVC 222 nm light is producing it by using high-frequency discharge excimer lamps filled with a mixture of noble gas molecule krypton (Kr) and normally less than 3% chloride (Cl) gas. These excited Kr/Cl emissions peaks of 222 nm from excimer lamps eliminate the use of hazardous materials like mercury and allow for near full power operation in only seconds, as compared to several minutes with legacy UVGI mercury vapor UVC lamps.

Far-UVC light created by excited noble gas provides the exact excimer lamp Far-UVC-light peak wavelengths necessary for AP-UVGI (Active Personnel Ultraviolet Germicidal Irradiation) Far UV lighting applications, using a very narrow frequency band of EMR (Electro-magnetic Radiation) found to be human-safe at between 207nm and 222nm wavelengths in a narrow band part of the electromagnetic spectrum referred to as Far-UVC light, which is generated by exciting KrCl molecules inside various power and wattage excimer Far-UVC light bulbs.

These days, open-source hardware is the rage among venture capitalists and technologists seeking to enter the Far-UVC light business. The idea for manufacturing Far-UVC light QuantaModule kits is for anyone from large OEMs, to small town lighting contractors or Far-UVC hobbyist to adapt and integrate AP-UVGI technology using 222nm Far-UVC light into whatever you like.

Figuring out the right amount of Far-UVC power and filtering longer wavelengths for occupied spaces and how to best design a Far-UV light system shouldn’t be left up to anyone who isn’t fully trained in Far-UV light disinfection technology.

Most scientists and engineers in the UV business now use the units “mJ/cm2” (millijoule per square centimeter) or “J/m2” (joule per square meter) for UV dose (the correct term is “fluence”). The units “J/m2” are used in most parts of the world except for North America, where “mJ/cm2” is used (1 mJ/cm2 = 10 J/m2. The old term “mW-s/cm2” (milliwatt-second per square centimeter) is equivalent to “mJ/cm2”, since a “W-s” is the same as a “J” (joule). Note that 1000 microwatt = 1 milliwatt.

The units “mW/cm2” (for fluence rate or irradiance) are often confused with the units “mJ/cm2” (for fluence or UV dose). The “fluence” (UV dose) is obtained by multiplying the “fluence rate” (or irradiance) (units “mW/cm2”) by the exposure time in seconds.

A continuous, very low dose rate of far-UV light in indoor public locations is a promising, safe, and inexpensive tool to reduce the spread of airborne-mediated microbial diseases.

2020 was a year of great despair, forcing us to reconsider the old ways. 2020 is also going down as the year outdated UVGI (Ultraviolet Germicidal Irradiation) technology made room for its predecessor — AP-UVGI (Active Personnel Ultraviolet Germicidal Irradiation) because this new AP-UVGI technology is completely safe for human occupants while destroying viruses in real-time in the presents of people.

The old way of using UVGI hasn’t changed much since its inception to prevent airborne disease by Wells in the early 1900s. Quanta X Technology has made it a vigorous mission to finish William Firth Wells’ work who pioneered UVGI innovation 100 years ago, which is still widely used today in health care settings just as it was a century ago.

We are certain if Wells were alive today, he would be shocked at the slow rate of innovation UVC manufactures have built on his discoveries using Germicidal Irradiation, that is, until now! AP-UVGI technology, Far UVC light companies have innovated UVGI more in the past 12 months than has occurred over the last ten decades. Active Personnel Ultraviolet Germicidal Irradiation, or simply AP-UVGI, the substitution of human-safe Far-UVC light replacing conventional mercury-line UVGI Ultraviolet-C light, is the most disruptive technology-based non-pharmaceutical pandemic countermeasure in human history.

Current UVGI depends on the use of UVC light wavelengths that destroy RNA/DNA viruses and harm human cells too when exposed to the most commonly used mercury line 253.7nm UVGI peak wavelength.

The use of current UVGI makes an area inaccessible to people during a standard UVGI Ultraviolet-C light disinfection process.

It doesn’t take a rocket scientist to figure out airborne transmission in an empty room isn’t a threat, and with UVGI, when the people return to a disinfected space, the threat of airborne spread returns with them! AP-UVGI targets active bio-agent threats when there is a real risk of airborne spread in occupied spaces.

The higher frequency used in AP-UVGI technology increases the photons’ energy responsible for neutralizing airborne bio-hazards and human safety by orders of magnitude over conventional UVGI. New AP-UVGI technology delivers these higher energy photons with a corresponding wavelength that studies have shown does not harm skin nor the eyes.

More precisely, within an infinite range of EM frequencies, the biggest advantage is that AP-UVGI uses a tiny “sweet spot” of EMR (Electromagnetic Radiation), completely safe for human exposure. This Far-UVC wavelength sweet spot that Dr. David Brenner brought to light is located in an extremely narrow part of Far-UVC’s section of the electromagnetic spectrum between peak 207-222nm wavelengths. Such a breakthrough now allows for Active Personal to be in the area being disinfected in real-time using only nature’s invisible shortwave Far-UVC light for extremely effective human-safe Ultraviolet Germicidal Irradiation.

AP-UVGI

Active Personnel Ultraviolet Germicidal Irradiation

The most commonly used lights have a wavelength of 254 nanometers (nm), which has a relatively short UV wavelength—the so-called “C” category—but can penetrate the skin and eyes, leading to cancer and cataracts. For the past 4 years, a group led by physicist David Brenner at Columbia University Medical Center in New York City has tested shorter wavelengths, known as “far UVC light,” that can’t penetrate the outer layers of the eyes or skin. The researchers found that Far UVC eliminated bacteria on surfaces and did not harm lab mice.

Complete QuantaGuard filtered excimer lamp 222nm Far-UVC light assembly with remote control, motion sensor, loop LED display timer, and 24V power supply is available in three QuantaGuard excimer lamp models: 5-Watt, 15-Watt, and 20-Watt. Seen below.

The invention increases the safety of both staff, patients, and their relatives by reducing the risk of contact with bacteria, viruses, and other harmful microorganisms. The concentrated Far-UV-C light emitted has a powerful yet very safe germicidal effect that removes virtually all airborne viruses and bacteria on a room’s surfaces.
