What is an appropriate humidity level in my home?
In short, the optimum humidity for an indoor environment is between 30% and 50%. The more control you can have over your indoor humidity, the more control you have over mold and bacteria growth, and thus more control over the health of your home. Sensitivities to relative humidity vary from person to person. Maximum comfort will result when you adjust to these individual sensitivities. Some homes require a whole house dehumidification system to control and maintain the optimal healthy range of indoor relative humidity.
