A Safer, healthier, and more productive environment for students, teachers, and staff

With educational institutions beginning to reopen, it is critical to ensure that classrooms, lunchrooms, and student dorms are filled with fresh, clean air that keeps students and staff safe as study resumes. This is especially important given that most HVAC systems were designed without closely considering the spread of airborne pathogens.


The CDC has provided clear guidance on the importance of social distancing for preventing disease spread. But as we know, social distancing is not always possible. Recent studies point to face coverings as another viable solution for reducing spread. But with some people not wearing masks, wearing them incorrectly, or using face coverings with lower blocking efficiency than high-grade medical masks, airborne droplets are likely to linger – especially indoors.
A recent New York Times article linked to a report by 239 scientists from 32 countries suggesting that the Coronavirus is indeed highly transmissible in enclosed spaces via airborne particles that linger in the air. This provides strong evidence that an air filtration solution can help keep us all safe as we work to get back to normal life.
