Study Sheds Light on How to Improve the Safety of Indoor Spaces

An Oregon-based study has found that ventilation, filtration, and humidification interventions reduce the level of SARS-CoV-2 circulating in the air. The study involved 11 subjects all with diagnosed cases of COVID-19 who performed various indoor activities such as talking, coughing, standing, sitting, and walking on a treadmill. Researchers then measured the level of the novel coronavirus following each of these activities, and made adjustments to the ventilation, filtration, and humidity in the same room. Boosting the ventilation and filtration in the room was effective at limiting the amount of viral particles in the air as was increasing the humidity. Click here to read more.
