How Gearing up with “UVGI Air Purification” will Help Corporate Offices in the Post Pandemic
Organizations are working judiciously on a comprehensive on-site return plan as they welcome employees in the aftermath of the Omicron wave. It is natural that employees expect their employers to ensure their workplace safety and help them navigate the challenges of resuming office in the new normal. A safe work environment is also necessary to boost employee morale and productivity.
While social distancing, proper masking, and sanitization are basic and undisputable norms, organizations need to go beyond them. One of the most crucial factors that corporate offices need to consider in their workplace safety approach is to monitor Indoor Air Quality (IAQ) and mitigate the risk of COVID-19 transmission. This is because small, micron-scale aerosol droplets can spread from an infectious person and move throughout the indoor space. This problem can worsen in the summer season when air-conditioning units run throughout the day and doors and windows are kept closed, as a result of which employees breathe only recirculated air.
According to a study titled ‘How can airborne transmission of COVID-19 be minimized’, inhaling small airborne droplets is a common route of infection, apart from transmission via larger respiratory droplets and direct contact with infected persons or contaminated surfaces. Another study ‘Ten scientific reasons in support of airborne transmission of SARS-CoV-2’ published in the Lancet journal mentions that transmission of this virus is higher indoors than outdoors.
While WHO and CDC recommend that good indoor ventilation is the key to targeting airborne transmission and limiting infection risk indoors, it is not enough. Corporate offices also need to review their HVAC system and air filtration technology to improve IAQ. In fact, CDC advises using Ultraviolet Germicidal Irradiation (UVGI) as an auxiliary technique to inactivate potential airborne viruses in the upper air room of common occupied areas.
How UVGI Can Help in Air Purification
UVGI is a disinfection method that uses short-wavelength ultraviolet light in the range of 200-280 nm to naturally destroy or inactivate viral, bacterial, and fungal microorganisms and pathogens in the air. ISHRAE states that UVGI damages the structure of nucleic acids and proteins in microorganisms at the molecular level, thereby inactivating them and rendering them incapable of reproducing.
When installed in HVAC units and air purifiers, UVGI can be highly effective in improving IAQ and preventing the spread of coronavirus. A quasi-experimental study showed that UVGI was associated with a 99% reduction of microbial and endotoxin concentrations on irradiated drip pans and cooling coils in HVAC units of office buildings.
UVGI installation in HVAC systems in offices offers the following other benefits:
- Prevents contamination of the air.
- Alleviates disease transmission.
- Controls the growth of mold, spores, biofilm, and other allergens.
- Eliminates volatile organic compounds
- Removes odors.
- Provides higher energy efficiency.
There is no doubt that UVGI for HVAC is a long-term and effective technology in air purification. It can be a frontline solution for corporate offices to fight against pandemics and contribute to the safety and well-being of their employees.
How Can Alfaa UV Help?
Alfaa UV has been actively deploying UVGI solutions in HVAC systems in corporate offices, commercial buildings, and other indoor spaces for 20 years.
