Far-UVC 222nm light is a highly effective disinfection method with proven efficacy across various environments and regions.

These systems effectively eliminate bacteria, viruses, yeast, and mold, all while remaining environmentally friendly.

FUV-C 222nm desinfection lamp

The UV-C 222nm lamps are designed to disinfect spaces safely and effectively, without the use of harsh chemicals. This non-toxic technology utilizes Far-UVC photonic light to kill germs, bacteria, and viruses on both surfaces and in the air. Our UV-C excimer light systems are energy-efficient and can be used with minimal disruption to your daily activities, offering an eco-friendly and safe solution for maintaining a clean and healthy environment. With a high level of germicidal activity, the 222nm light is safe for use in occupied spaces, including areas with limited ventilation. These 222nm excimer light systems are ideal for residential, commercial, and industrial environments, including hospitals, schools, subway stations, and airports.

Air Disinfection from the White House: UV-C 222nm sterilization light systems inactivate ("kill") airborne viruses, providing an additional layer of protection in indoor spaces. This advanced technology is particularly effective in crowded areas with poor airflow, healthcare settings with vulnerable populations (such as hospitals or nursing homes), and environments like restaurants where people are unmasked while eating and drinking. For example, one study showed that when used with proper ventilation, UV-C 222nm light is approximately 9.9% effective in reducing the spread of airborne tuberculosis, equivalent to replacing the air in a room up to 24 times per hour.

Sterilization is essential in environments with a high risk of airborne transmission of viruses, bacteria, or pathogens, including COVID-19, tuberculosis, smallpox, severe acute respiratory syndrome (SARS), and pandemic influenza. Together, these illnesses impact over one billion people annually.

Surgical site infections (SSIs) remain a significant complication in surgical procedures. Current evidence indicates that most SSIs are caused by bacteria settling directly onto the surgical wound from the air.

Far-UV radiation excilamps efficiently and safely inactivate all mutations of airborne coronaviruses, including COVID-19. They are effective in both occupied and unoccupied spaces, such as underground mines, military facilities, kindergartens, and schools.

Efficient cleaning of laboratories and meat packing facilities, sterilization of greenhouses, and cold chain disinfection for frozen food exports—now mandated by many countries, including China.

Excilamps effectively remediate polluted air streams while enabling photochemical detoxification and purification of water contaminated with organic substances and bacteria.

Sterilization solutions are suitable for a wide range of environments, including airports, restaurants, sports facilities, airplanes, trains, buses, horse stables, animal farms, cars, cruise ships, commercial offices, factories, and schools.

The Far UV excilamp, operating at a wavelength of 222 nm, was evaluated for its efficacy against various bacterial species. Our findings indicate that lamp achieved 99.9% bacterial disinfection, even in the presence of a substantial shielding effect observed at high initial populations.

A Columbia University study showed that 222nm FUV-radiation’s narrow band of wavelengths is short enough to prevent it from damaging living human cells, but it can still penetrate and kill small viruses and bacteria on surfaces and in the air.

Here we extended our previous studies to 222nm light and tested the hypothesis that there exists a narrow wavelength window in the FUV-radiation region, from around 200–222 nm, which is significantly harmful to bacteria, but without damaging human cells in tissues.
