- 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.
