applications, commercial settings, and even schools. HEPA filters are designed to capture 99.97% of particles that are 0.3 microns or larger. 2 If we see a significant shift toward HEPA media, it is worth noting that some HVAC systems will need to be upgraded to augment air flow, in order to balance increased system pressure requirements against more efficient filtration media. With this increased emphasis on filtration comes higher performance requirements and greater demands on filter media, including more frequent filter changes.

With this increased emphasis on filtration comes higher performance requirements and greater demands on filter media, including more frequent filter changes. It is also likely that many HVAC system designers will need to begin considering the impact of high performing filtration media on HVAC system airflow and energy requirements to ensure that system performance does not suffer as a result of improved filtration.

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.
