The device that is primarily responsible for maintaining proper temperature in sterile areas of a medical facility is the thermostat. A thermostat monitors the ambient temperature and regulates heating or cooling systems to ensure that the environment remains within the required temperature range suitable for sterile conditions.

In medical settings, maintaining a specific temperature is crucial for preventing the growth of pathogens and ensuring the effectiveness of sterilization processes. By accurately controlling temperature, the thermostat plays an essential role in supporting the safety and efficacy of medical procedures that occur in these sterile environments.

While humidity control, air filtration, and thermal blankets each serve important functions within a medical facility, they do not specifically focus on temperature regulation in sterile areas. Humidity control helps manage moisture levels, air filtration ensures that contaminants are removed from the air, and thermal blankets are used for patient heating and comfort, rather than for maintaining sterile conditions in a broader sense.
