Whole house humidifier units are installed inline with your heating system and will disperse moist air into your home through your air ducts during heating cycles while stand-alone units come in various sizes and can be targeted to specific rooms or areas of the house. Both types work to help make your air more pleasant and fight the effects of cold, winter weather indoors. Humidifiers simply increase your indoor humidity by adding moisture to your air.
