Health and Relative Humidity of Air

The optimum relative humidity ranges for bacteria, viruses, fungi, mites, asthma.

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.
