Before we define what a whole house humidifier is and does it work, we’ll define exactly what a humidifier is first. A humidifier is an appliance that adds moisture into the air and prevents dryness usually associated with winter when houses are closed  up and for the winter with the heat on. 

For many people, that dryness irritates their lips, nose, skin, and throat. A humidifier is used for to ease cold and flu symptoms as well. It has been proven that a humidifier is good for asthma, and because a family member with asthma isn’t likely to spend all their time in one room of the house, a whole house humidifier is more beneficial to that person as well as the entire family and the home. 

Where a vaporizer provides warm, moisture in the air, a humidifier provides both cool and warm air in the form of vapor mist. This enables you to regulate the humidity that can make conditions worse for an asthmatic person. When using only a single portable humidifier, using a fan with the unit will circulate and spread the moisture air throughout the room. A whole house humidifier will do this through the HVAC system, spreading the treated air through the house, performing similar to a humidifier like a fan.
