A House Humidifier is an essential device that is connected to the central heating system of the house. It is used to insert controlled amounts of moisture into the heated airflow from the furnace.  It is the function of the humidifier to bring about a change in the air quality and create a balance in the humidity level of the house. Water vapor travels throughout the house with the help of a humidifier keeping humidity levels in a healthy and comfortable range.  When controlled humidity level is introduced within a home, it prevents condensation of water on walls and other surfaces but keeps the air moist enough for warmth and comfortable for breathing. Humidifiers are important as they increase the amount of moisture in the air. This moisture becomes necessary during winter season.

A House Humidifier provides environmental control within the entire house.  The humidifiers are such apparatus that is commonly used in homes to ease the discomforts of dry nose, throat, lips, and skin during dry weather.  These devices add moisture to dry air thus helping to relieve the common problems brought by winter heating, such as static electricity or cracks in paint and furniture.   Researches through Environmental Protection Agency (EPA) and the Consumer Product Safety Commission (CPSC) show that ultrasonic and impeller or cool mist humidifiers are the mostly used humidifiers that can disperse materials, such as microorganisms and minerals, from their water tanks into indoor air.

A House Humidifier should be properly cleaned and maintained.   Care should be taken while cleaning of ultrasonic and impeller humidifiers as they are important for reducing possible exposure to microorganisms, such as bacteria and molds. Microorganisms are found to grow in humidifiers which are equipped with tanks that contain standing water. It is suggested that using water with lower mineral content reduces exposures to these materials. Using a humidifier includes several advantages in a home.  These devices decrease unpleasant symptoms that are caused by dry air.  Humidifier relieves the sinus inflammation, prevent chapped lips and dry, itchy skin. It tries to keep the home in a comfortable range while relieving the symptoms of illnesses like colds and flu.
