COVID Paradigm Shift

As the current pandemic wears on, we continue to learn how this virus spreads from person to person, and how we can prevent this spread. Contrary to its original stance, the CDC now states in a scientific brief that airborne transmission of the virus that causes COVID-19 is not merely likely but commonly occurs in conditions such as enclosed spaces, prolonged exposure, and poor ventilation/air movement.

As our knowledge about the germs that cause illnesses deepens, we revisit the ways that we defend against them. Sometimes we simply need to bolster existing practices, but sometimes we need to shift our way of thinking first to take the necessary precautions.

Five Paradigm Shifts Pertaining to Air Filtration and Illnesses

Threat Posed by Airborne Transmission

When a contagious person sneezes, coughs, talks, or even breathes, infectious particles spread throughout the room and contaminate the air in it. However, those same particles can enter the return air ducts of the HVAC system, which then circulates those particles throughout a building.

Clean Air Is the Answer

The solution to this problem, as recommended by ASHRAE, involves diluting the concentration of infectious particles with increased amounts of outside air, and cleaning the air with filters with an efficiency rating of at least MERV 13.

Upgrading from a MERV 7 air filter to a MERV 13 filter reduces the likelihood of infection by nearly 40%.
