UV Light: A New Approach to Disinfection

The Ongoing Fight Against COVID-19

The COVID-19 pandemic has claimed over 6 million lives globally as of March 16, 2022. While significant progress has been made in developing effective vaccines, it’s equally crucial to implement strategies that prevent the spread of the virus. In public spaces like offices and hospitals, alcohol and acid-based disinfectants are commonly used to minimize the risk of transmission. However, these methods are not suitable for disinfecting drinking water or purifying the air, leaving gaps in our overall infection control measures.

The Potential of Sunlight in Disinfection

This is where the natural power of sunlight comes into play. Dr. Nimai Pathak, in collaboration with C2ST and WorldChicago, is exploring how ultraviolet (UV) light from the sun can be harnessed to kill germs. This innovative approach could provide a sustainable and efficient way to disinfect environments without the limitations of chemical disinfectants.

Introducing Care222: A Safe and Effective Disinfection Solution

One of the latest advancements in UV disinfection technology is Care222, a light source that safely deactivates bacteria and viruses without harming human or animal skin or eyes. Unlike conventional UV sanitizers, which can be harmful to living tissues, Care222 uses a specific wavelength of UV light—222 nm—that is both effective and safe.

This technology can be installed in high locations, such as ceilings, allowing it to irradiate and disinfect the entire surrounding area. Care222 effectively neutralizes a broad spectrum of viruses and bacteria, both in the air and on surfaces, making it an ideal solution for maintaining clean environments in spaces where people are present.

How Care222 Works

Care222 operates using a mercury-free excimer lamp, specially developed by Ushio, which emits monochromatic ultraviolet light at a primary wavelength of 222 nm. The lamp is paired with a unique optical bandpass filter that allows only safe UV wavelengths (200 to 230 nm) to pass through, ensuring no harmful effects on people.

This innovative light source has been integrated into My Lumens’ Artemis far UVC devices, which are designed for use in occupied spaces. These devices help keep air and surfaces clean, providing a continuous and safe method of disinfection.

Conclusion

As we continue to battle the spread of viruses, including COVID-19, technologies like Care222 offer promising solutions for disinfecting public spaces in a safe and effective manner. By leveraging UV light in new ways, we can enhance our ability to create healthier environments, ensuring greater protection for everyone.
