Final answer:
The furnace needs to be operating when an atomizing humidifier is used because it provides the necessary heat for the water to evaporate and create moisture in the air. Without the furnace, there would not be enough heat to vaporize the water effectively. This is important for improving indoor air quality and creating a more comfortable environment.
Step-by-step explanation:
When using an atomizing humidifier, it is essential for the furnace to be operating because the furnace provides the necessary heat for the water to evaporate and create moisture in the air. The furnace heats the air, which then passes over the water in the humidifier, causing it to evaporate and release moisture into the air. Without the furnace, there would not be enough heat to vaporize the water effectively.
For example, imagine a scenario where the furnace is not operating, and an atomizing humidifier is used in a cold room. The water in the humidifier may not be able to reach the necessary temperature for evaporation, resulting in little to no moisture being released into the air. The room would remain dry and lacking in humidity, which can have negative effects on the respiratory system, skin, and overall comfort.
By ensuring the furnace is operating, the atomizing humidifier can effectively add moisture to the air, improving indoor air quality and creating a more comfortable environment, especially during colder months when heating systems are commonly used.
