Effective Disinfection of Air in Commercial Buildings Using UVC Light

Commercial buildings are a great place to work and network. At the same time, they seem to house unimaginable microbial contaminations. The recirculation of air within these buildings affects the total air quality. And this stands as the prime reason for microbes to plunge in. The contaminations hail from outside air, as well as indoor air. The chances for respiratory infections are higher in this case.

With this poor air quality in commercial buildings amid the COVID-19 coronavirus pandemic, the situation can worsen. In this case, the chances of infections can increase dramatically among people. This makes these commercial buildings unsafe.

Disinfection of Coronaviruses in the Air

As per the WHO’s scientific brief, there are chances for the COVID-19 coronavirus to transmit through air. Hence, for the welfare of the (uninfected) people, the WHO has recommended adequate precautions to prevent airborne transmissions.

When it comes to disinfecting the air, radiation methods are preferably adopted. Among the various radiation methods, such as non-ionizing radiations and electromagnetic radiations, ultraviolet (UV) light radiation seems promising. Let’s look in detail at how UV-C light irradiation of air helps disinfect COVID-19 coronavirus and similar deadly microbes.

UV Light for Air Disinfection in Commercial Buildings

Decades ago, scientists found that UV light with 200 – 280 nm wavelengths possesses germicidal properties. Many experiments conducted in the past have studied the potential of UV light to destroy various bacteria, viruses, fungi, and molds. Backed by research, experimental, and observational studies, UV light gained momentum in practical applications at various industries and manufacturing units. 

Kowalski et al. research has studied in depth the potency of ultraviolet germicidal irradiation (UVGI) for air and surface disinfection of commercial buildings. The research finding claims that ultraviolet germicidal irradiation serves as one of the economical disinfection options to sterilize the air of commercial buildings.

Effectiveness of UVC light for Air Disinfection of COVID-19 Coronaviruses

A group of researchers carried out an efficacy study using a UVC disinfection system to kill selected strains of coronaviruses, namely MHV, SARS-CoV, and MERS-CoV. The study resulted in more than 99.99% destruction of viruses with just 5 minutes of UVC irradiation. This undetectable viral load of coronavirus upon UVC light disinfection enlightened the road to disinfecting the COVID-19 coronavirus with UVC light.

Check out the smart UVC light sanitizer that disinfects air and surfaces in no time. Watch this demo! You’ll figure out how UVC light efficiently acts against harmful microorganisms, including the coronavirus strains. This PXL UVC light sanitizer proves efficient in destroying coronavirus strains, like Sars-Cov-2, SARS-CoV-1, and MERS-CoV. This cutting-edge application of ultraviolet light includes not only commercial buildings but catering units, production units, laboratories, hospitals, restaurants, breweries, beverage factories, bus and rail stations, and a lot more public places.

Other Advantages of UVC Light Disinfection in Commercial Buildings

  • Exquisite upper air sterilization when used as fixtures
  • Surface disinfection of doorknobs, handles, and other high-touch surfaces
  • Floor-level disinfection
  • Both indoor and outdoor air disinfection
  • Toilet surface disinfection
  • Disinfection of objects and things carried by people
