Healthy Spaces Ecosystem

An Indoor Air Quality Revolution

We’ve learned the importance of indoor air quality, in our schools, hospitals and every building we enter. New guidance from the Centers for Disease Control and Prevention (CDC) provides concrete recommendations building owners should follow to create the healthiest spaces where we spend the most time.  The CDC’s new Health Based Ventilation guidance* states, when possible, aim for 5 or more air changes per hour (ACH) of clean air to help reduce the number of germs in the air. This represents an important step forward in achieving cleaner indoor air for all. 

Explore the different factors and guidelines to effectively improve indoor air quality.
