1. Humidity control prevents static electricity, which helps protect medical electronic instruments and is safer for medical staff and patients.
2. Humidity control prevents the proliferation of bacteria and biological pollutants, and air humidity is required to be maintained at around 40%~60%.
3. Humidity control prevents the increase of airborne dust. In winter, dry air can increase the amount of airborne dust, which can lead to allergies and asthma problems.
4. Proper humidity control can not only reduce odors, but also increase patients' physical and mental comfort, and promote wound healing speed.
Usually, the government or relevant units have regulations or restrictions on the air conditioning environment in different areas of hospitals, as shown in the attached table:
| Hospital area | Temperature | Relative humidity | |
| Rehabilitation Room | 24℃ | 50% | 60% |
| Operating Room | 20~24℃ | 50% | 60% |
| Delivery Room | 21~24℃ | 50% | 60% |
| Intensive Care Ward | 22~24℃ | 30% | 60% |
| Baby Room | 24℃ | 30% | 60% |
| Radiology Room | 22~24℃ | 40% | 50% |
| Computer Room | 22~24℃ | 30% | 45% |
| General ward | 24℃ | 30% | 60% |
These places generally use steam humidification, as steam is a high-temperature sterilized gas with no bacteria present. However, it is important to note that the humidification system should not have dripping or condensation to prevent it from becoming a breeding ground for disease vectors.
※ Specific selection method
There is sufficient boiler steam on site, and it is recommended to use boiler steam humidifiers;
There is insufficient boiler steam and pure water on site, so it is recommended to use an electric steam humidifier;
There is not enough boiler steam or pure water on site, so it is recommended to use an electrode type steam humidifier.
