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.
