Why Humidify?

The Sterling Chart was introduced in 1985 to show the relationship between relative humidity and typical indoor contaminants at normal room temperatures.  Since that time, there have been copious research documents linking 40-60%RH with less effective aerosol travel, shorter airborne and surface survival times & lower transmission rates of contaminants in buildings.  Keeping your indoor relative humidity between 40-60% is critical to ensuring a healthy environment.

In a recent study, J.W. Birks and Kathy Rowlen, investigated the correlation between influenza cases in schools and indoor relative humidity (RH).  (Maintain Classroom Humidity at 40-60%RH)  They summarize that “We should humidify our school classrooms now!”.  The following is a graph from the study that creates a vivid picture of the correlation between RH and influenze cases.
