Different Ways to Combat Coronavirus in Indoor Air Environments

While some areas of the world are beginning to see faint glimmers of hope in getting the upper hand on the frightening and devastating coronavirus pandemic, the number of deaths and serious illness continue to climb. The most talented medical professionals on earth are working fervently to devise a vaccine or at least temporary treatment and most everyone is learning as they go in valiant attempts to maintain some semblance of normalcy.

An oft-neglected subject of conversation is indoor air quality. With so many people confined to their homes in this time of lockdown, the potential is great for the virus to take hold and spread throughout the building.  For example, some air quality experts suggest that small droplets containing the COVID virus could drift around in the air of a home for extended hours, get drawn into the HVAC ducts and travel to a different room and infect other people.

A quick review: the current COVID-19 scourge is part of a very large group of coronaviruses that cause a range of symptoms from everyday head colds to flu-like conditions to more severe breathing issues. The virus is transmitted through the air as well as contact with infected surfaces (think doorknobs, phones, keyboards, countertops) followed by touching areas of the face. The virus is a stubborn one and can live on hard surfaces at room temperature for roughly 9 days. Fortunately, it is not particularly robust and can be killed with common disinfectants.

Combatting coronavirus indoors

In high-occupancy buildings, it is especially important to mount a stalwart defense to keep the virus in check. This is best accomplished through a strategic array of proven attacks leveraging a high-quality HVAC system.

Start with a quality air filter

All air filters are built to remove tiny particles of dust and other pollutants from the air. However, to best protect against COVID-19, a filter capable of filtering the tiniest of microns (coronavirus weighs in at about 0.06 to 0.14 microns) is required.

Decontaminate surfaces and HVAC system

A targeted treatment of indoor air and HVAC ductwork helps sanitize air moving inside the building, as well as remove COVID and other viruses from high-touch surfaces.

Apply HVAC germicide

Special UV lights can be highly effective in killing most bacteria, mold, and viruses clinging to various HVAC surfaces and equipment.

Get humid

Most viruses, including COVID, lose their oomph when humidity falls in the 40-60 percent range. With that in mind, leverage your HVAC system to dial in humidity to that range and help keep viruses at bay.
