COVID-19 Brings Indoor Air Quality Monitoring Upfront

As the country begins to emerge from the cloud of the COVID-19 pandemic, one of the challenges is to provide peace-of-mind by making homes and workplaces in Waterford, MI and Oxford, MI as safe as possible. Additionally, infectious disease experts warn this won’t be the last time the world faces a deadly pandemic. It may not happen again for decades, or it could happen next year. That’s why Kotz Heating, Cooling & Plumbing wants to have this conversation about indoor air quality.

Why It’s Important

Here is a startling conclusion from recent research: Improving indoor air quality (IAQ) could have the same beneficial effect as vaccinating half the population when it comes to reducing aerosol transmission of viruses like COVID-19. For many years IAQ has focused almost exclusively on particulates, carbon dioxide, and volatile organic compounds. The pandemic has led to a broader focus on elements that affect viral survivability including:

  • Humidity
  • Temperature
  • Lighting

Virus Transmission

The spread of COVID-19 is mostly through droplets (coughs, sneezes, etc.) and aerosols which are smaller particles and can be compared to a mist. Both are terms we’ve likely become all-too-familiar with in the past year. The challenge is finding ways to minimize the spread.


The longer a virus is able to survive, the more likely it is to spread. One of the best ways to shorten the duration is with correct humidity levels of 40 to 45 percent. When the air is very dry, more than 70% of the viral particles can cause infections. When the humidity is raised the number drops to about 18%.

A Three-Pronged Attack

With all this information in mind, Kotz believes the best approach to virus control in Waterford, MI and Oxford, MI is a three-pronged attack to improve indoor air quality:

Advanced Filtration

By this we mean upgrading from the standard 1-inch HVAC filters. Some choices include:

  • 4-Inch media filters which trap much smaller particles in the air.
  • Activated carbon filters that can chemically neutralize many elements.
  • Advanced HEPA filtration when used with compatible heating & cooling systems.

Air Purifiers

These do more than trap particulates. Ultraviolet light and ion generating systems are also capable of killing COVID-19, other viruses and bacteria.

Proper humidification

As indicated earlier, a whole-house humidifier is the best way to keep the air from getting too dry. This will limit the spread of viruses by shortening the length of time they can survive in the air and on surfaces.
