However, despite the name “COVID-19 Healthcare ETS” the rule applies to any organization that provides first aid […]

The COVID-19 pandemic taught us many things. For facilities managers, it further stressed the importance of building health. While managers and engineers have long understood the relationship between indoor air quality and the health of building occupants, the pandemic prompted stakeholders to refocus resources on creating safer, healthier buildings, and that includes clean HVAC systems. […]

Many schools across the United States operate with older HVAC systems. In fact, a recent U.S. Government Accountability Office report found that as many as 54 percent of public schools in the U.S. need to replace or repair their HVAC systems.

Effective air filtration is key to maintaining good indoor air quality. In fact, you could say that an HVAC system is only as good as its air filtration system. The main function of the filtration system is to keep heating and cooling coils dust- and dirt-free, but it also works to limit chemicals, gasses, and […]

We might think we are safer inside than out when it comes to breathing dirty air but the fact is, that indoor air is oftentimes much more polluted than the air outdoors.

The U.S. has not faced a public health crisis like COVID-19 in over a century. Back then we did not have the mechanical systems we have today. This presented a new challenge for school building engineers. Many HVAC systems required maintenance and updating and some of the air quality measures now required were not supported […]

As the COVID-19 pandemic continues its hold on world health, the emergence of fungal infections has the scientific and medical communities concerned. Pulmonary Aspergillosis is chief among them. At Pure Air Control Services, we cautioned building managers about the dangers of this infection long before the SARS-CoV-2 outbreak occurred. In fact, we talked about the […]

  One might think that rapid air changes would be a good way to dilute the SARs-CoV-2 virus and prevent its spread throughout a building. While this seems intuitive, new studies show this isn’t the case. In fact, rapid air changes spread the virus from the source at higher concentrations. Within 30 minutes of an […]
