As a cleaning business, we always study the latest cleaning research and technology, especially as we face the COVID-19 pandemic. One technology that is gaining popularity is the use of Upper-Room Ultraviolent Germicidal Irradiation or UVGI. The CDC has even endorsed using this technology to improve ventilation and prevent the airborne transmission of COVID-19 and other viruses.
UVGI technology uses ultraviolet (UV) energy to kill viral, bacterial, and fungal materials. UVGI fixtures are installed in the upper areas of rooms as part of an HVAC system. This technology uses penetrating UV rays to create a disinfection zone high in the air at the top of the room, where there is no direct exposure to people. As the air passes through the disinfection zone, the UV rays charge the particles, killing airborne organisms and pathogens as they are released.
UVGI provides an additional layer of protection that can be helpful in the fight against airborne transmission of viruses and bacteria, including COVID-19. Upper-Room methods aren’t the only way that UV light is being used in the fight against COVID-19. UV lights and lamps are also being used to disinfect surfaces and kill bacteria. However, upper light UVGI is best used to kill airborne transmissions that may hang in a room. The CDC says places that may benefit the most from the use of UVGI technology include:
- Areas with high concentrations of sick people
- Crowded spaces
- Spaces where people are maskless
- Areas where physical distancing is not possible
As a cleaning firm, we know that you want to protect your business and patrons from harm. Installing UVGI technology may be one tool you can use to prevent the spread of airborne disease, including COVID-19. But there are a few things you need to consider before installation.
- UVGI technology is decades old and considered safe, as long as trained technicians properly install it. Ensure that you have a qualified HVAC specialist with training in UVGI to install any systems for you to prevent direct UV exposure.
- UV lights may damage plants in the disinfection zone and cause discoloration to paint or wallpaper.
- Ensure to properly train your team and anyone who uses your space to turn on and use the UVGI system.
- UVGI systems are expensive. It may cost up to $2,500 for 500 sq ft.
- UVGI systems require little maintenance once installed by a qualified technician. However, they require cleaning a few times a year to remove dust and debris, and lamps may need to be replaced once a year.
UVGI technology can be a helpful tool in the fight against COVID-19 and the common cold, influenza, and other airborne viruses.
