Health vs. Relative Humidity

Relative humidity (RH) should be within certain limits for control of the health aspect.

• Bacteri : 20 - 70% RH
• Viruses : 40 - 80% RH
• Fungi : 0 - 70% RH
• Mites : 0 - 60% RH
• Respiratory infections : 40 - 50% RH
• Allergic Rhinitis and Asthma : 40 - 60% RH
• Chemical interactions : 0 - 40% RH
• Ozone production : 75 - 100% RH
• Combined Health Conditions : 40 - 60% RH

In general - relative humidity for human comfort ranges 30 - 60% RH.
