Super-spreaders Don't Have to Be Human, They Can Be a Building's HVAC System

A news press release by Hartford Healthcare on July 13, 2020, discussed the threat of a building’s heating, ventilating, and air conditioning (HVAC) system on the dispersal of the SARS-CoV-2 virus that causes COVID-19 throughout the building. After over 200 scientists wrote into the World Health Organization urgently requesting that they add airborne transmission to the list of ways the virus can spread, the WHO changed their statement to include that airborne transmission cannot be overlooked. HVAC systems create air currents that enable large viral particles to travel throughout the building’s rooms through the ductwork. According to Chinese health officials, this is how 10 people from three families tested positive after eating in a restaurant. These families were spread apart from one another, so the clue to leading to the transmission was the HVAC system. 

It is recommended that a redesign of the pre-existing HVAC system needs to be completed, or the implementation of technologies that can work with the current system. Such technologies would include the use of a high-efficiency particulate air (HEPA) filter, bipolar ionization, and ultraviolet-C (UVC) light. 

ISO-Aire HEPA air purifiers incorporate up to three levels of clean air technology.

Combined, these three technologies would provide a powerful and effective way to safeguard the building’s air from germs such as SARS-CoV-2, creating a brighter future for all. At ISO-Aire, we have created a unit that offers this triple trifecta of protection at an affordable price, allowing buildings to meet the HVAC system needs to ensure safety while not breaking the bank.
