Improving Air Quality to Protect From COVID-19 (Part 1)

By now we all know that the main mode of coronavirus transmission is by aerosols and airborne droplets in close proximity.  Although most are aware of  the importance of wearing protective facemasks,  as vaccinations become more widely available and businesses begin to reopen, there also needs to be an emphasis on ventilation and air purification. Vaccinations greatly reduce the chances of contracting the coronavirus, but it is not a 100% guarantee; and unfortunately, there are portions of our population that cannot receive the vaccine, so it’s important to take precautions to protect those vulnerable.

Indoor Air Quality and COVID-19

Indoor environments are at much higher risk of transmitting airborne diseases such as COVID-19. This is because aerosols that are expelled naturally from the nose and mouth while breathing, talking, laughing, coughing, and sneezing are more likely to hang around when there’s no air flow. This is why the World Health Organization (WHO) recommends following a roadmap for assessing indoor air quality and doing as much as possible to improve ventilation. Some of the easiest ways you can improve air flow:

  • Turn on exhaust fans in bathrooms for an hour after people visit
  • Ensure HVAC systems provide outdoor air ventilation and run them more frequently
  • Open windows, aiming for cross-ventilation
  • Place fans in windows to further promote air exchange
  • Try to gather in larger rooms with fewer people

A recent BMJ article puts it succinctly, “Safe indoor environments are required, not only to protect unvaccinated people and those for whom vaccines fail, but also to deter vaccine-resistant variants or novel airborne threats that may appear at any time.”

Air  Quality is the Next Frontier of COVID-19 Protection

While disinfecting common-touch surfaces is important when protecting against COVID-19, air cleaning is more important. Scientists have shown that the virus is capable of lingering in the air for hours on end, even after the droplet source has left the building. It’s of utmost importance to take precautionary measures particularly because mask mandates are starting to lift all across the US.

Some of the most common ways of improving air quality include:

  • Increased outdoor air ventilation
  • Air filtration, both centralized in HVAC systems and portable units
  • Upper room Germicidal UV lighting systems
  • Air quality monitoring systems

Not only does having clean air reduce coronavirus transmission risk, it also protects against other respiratory diseases  such as the flu, seasonal colds, and potentially future pandemics. Having solid infrastructure for future disease outbreaks is never a bad idea — after all, the year 2020 taught us to expect the unexpected. The last thing you need is to be caught off guard by another novel airborne virus.

In fact, it’s even beneficial to your bottom line in the long-run. According to Science News, “In the United States alone, yearly economic losses from flu total $11.2 billion, and other respiratory viruses cost about $40 billion. COVID-19’s global monthly harm is estimated to be $1 trillion.”
