Q:

Which humidifiers are the most energy efficient?

A:

Quick Answer

However, these issues have been eliminated in newer models. In terms of the type of mist produced, cool mist humidifiers conserve more energy than warm mist humidifiers, as they don't have to use electricity to heat the water up.
