What is UVGI light and how does it boost the efficiency of air purification?

April 11, 2023

Nowadays, the quality of air in workplaces and commercial buildings is more important than ever. By implementing air purification systems, you can significantly reduce the amount of airborne pollutants and pathogens your employees and customers breathe in.

However, it’s important to keep in mind that not all methods are equally effective, and achieving the best results is possible only with reliable and approved solutions such as UV lighting. This technology has been tried and tested over the years and is now universally recognized as capable of destroying bacteria and viruses. So what is UVGI? And what is its role in making your business premises safer and cleaner?

What is UVGI?

Ultraviolet germicidal irradiation, or UVGI for short, is a disinfection method that utilises the sterilising properties of ultraviolet-C radiation (UV light with a wavelength ranging from 200 nm to 280 nm). It’s commonly used in healthcare institutions, commercial properties and spaces frequented by many people where the risk of inhaling contagious and harmful particles is especially high. With a UVGI system, up to 99.99% of pathogens can be deactivated, effectively preventing the spread of infections and creating a much safer and healthier work and business environment.

How does this technology work?

In order to fully comprehend the benefits of UV lamps, it’s important to understand how airborne diseases are transmitted. You can get infected either by coming into direct contact with someone who has the disease or by inhaling bacteria or viruses that linger in the air, for example, after a sick person coughs or sneezes. Without using any form of air purification or ventilation, these pathogens can remain active in the air for up to several hours.

However, microorganisms such as bacteria, viruses, and mould, among others, can be destroyed when exposed to ultraviolet lighting. The impact of UVC radiation triggers changes in their DNA and RNA, restricting their ability to multiply and thus neutralising their harmful effects and infectious potential.

Is ultraviolet light harmful?

UVC radiation occurs naturally in sunlight and artificially in UV lamps. Prolonged exposure to such light can cause serious health issues, including skin cancer, as well as skin and eye damage.

Fortunately, the ozone layer stops radiation emitted by the sun long before it can reach us, so the only possible source of exposure comes from man-made technology. Which does not mean that the use of ultraviolet light in disinfection and air purification is a health hazard. The UVGI light in AIR8 devices is safely contained within the unit, and its reach extends only far enough to irradiate the HEPA filter. This makes our systems perfectly safe to use, even in occupied spaces.

Are UVGI systems effective against viruses and bacteria?

Yes, UV irradiation is currently considered to be one of the most effective disinfection methods for air, water, and surfaces, with the potential to eliminate even 99.99% of hazardous particles. What makes this technology so successful? The organisms of disease-causing germs are simply not capable of surviving in the inhospitable conditions it creates.

Using ultraviolet light for business purposes

The ultraviolet-C light has been used in healthcare environments for a long time now as a safe and quick option to control the spread of pathogens and keep the air free of pollutants and germs. Nowadays, its application can be observed across various industries, from water treatment plants to medical facilities, office buildings, restaurants, shops, and schools.

How can UV light help your business?

  • Fewer absences due to the reduced risk of getting sick. Highly frequented areas are linked to a bigger risk of contracting airborne diseases because there’s a greater likelihood that an infected person will exhale pathogenic particles into the air. By utilising germicidal properties of UV light, you can prevent the spread of infections and create healthier conditions for everyone working in the building.
  • Providing a safe workplace can increase your employees’ productivity. Nowadays, people are constantly thinking about the potential risk of falling sick. The resulting stress can impact the quality of their work negatively. Equipping your business with a high-quality UVGI system can put such worries to rest and make their work easier due to improved psychological well-being.
  • Customers may feel more comfortable visiting your business. Your employees are not the only ones concerned with their health. By promoting your business as safety-oriented and willing to invest in effective disinfection and air purification methods, you can encourage more people to stop by and choose your services.

In short, if you have many employees or your office is frequented by customers, providing them with a clean and healthy breathing environment is essential. With air purifiers, you can transform your business premises, making them more comfortable and safer to use.
