What Is a Humidifier and Do You Need One?
A humidifier adds water vapor to the air to increase humidity. It adds moisture to the air in your home, with the end goal of optimizing indoor humidity levels. The term “humidity” simply refers to moisture in the air.
The term relative humidity is the percentage of moisture in the air compared to what the air can hold at a given temperature. The optimal indoor humidity level is typically between 30% and 50%, according to the EPA, which means it’s best to have air containing between 30% and 50% relative humidity in your home.
