A humidifier can be set and works to regulate the humidity.

Most good humidifiers for home use are controlled by a sensor built into the unit. The sensor reads the humidity value in the area it is located. This humidity value is referred to as Relative Humidity, and this is the percentage of moisture in the air relative to the temperature.

A humidifier can be set and works to keep the humidity levels between certain percentages – a low and a high value – and when either one is reached it triggers the unit to turn on or off. When it senses that the humidity in the air is low, the unit turns on and moisture is added to the air, and when the upper level is reached, the humidifier shuts off. In other words, it regulates the humidity.

If you are unsure what the levels of humidity are in your home, you can purchase a hygrometer to monitor and do spot checks in different rooms of your house. Click here for more information on different hygrometer options.
