Studies have shown that indoor air is significantly worse for people than outdoor air. As we have learned from the COVID-19 pandemic, having the proper ventilation helps keep occupants safe and healthy. For small and mid-size commercial buildings, this is especially important as it can be easier for viruses to travel. It is up to facilities managers to regularly test their ventilation systems in order to ensure that the building is not only up to code, but that it also remains a safe place to be. In this video by Slipstream, Ryan Hoger, director of training and temperature equipment corporation, discusses what tests managers can do to ensure their building is properly ventilated.
