In addition to cutting energy bills, humidifiers also help alleviate the problems caused by dry air including itchy skin, scratchy throats, static electricity, and damage to furnishings and woodwork.
The relative humidity in a home should ideally be in the range 20 to 40 percent. Over-humidifying can lead to condensation on windows and dampness on walls.
Compare with dehumidifier.
