Central humidifiers go to work when the heat is turned on, and starts to humidify the air during the heating process. The moisture comes from the home plumbing system directly into the humidifier. Portable humidifiers differ in that they must be manually filled with water periodically. Though there are different types and brands of central humidifiers, all perform the same job.

Some airborne pathogens are able to circulate through the home easier when dry condition exist. One example would be the pathogens known for causing the flu. Humidity may also help those who are suffering from a cold to breathe easier. Dry indoor air can also be problematic to those who suffer from chronic dry skin. Dry air can also damage certain elements of the home such as wallpaper, paint, items made of wood, and more.

Though not considered to be dangerous, there are a few problems that can be caused by their use. If bacteria or fungi are allowed to grow in the humidifier, these can be transferred into the air an inhaled. Illness or disease could be the result. Problems more commonly occur due to portable humidifiers, as owners of such devices may not change the water frequently enough.

 

If the humidity level is kept too high, condensation could be the result. Condensation can damage damage walls and windows. Another consideration would the the possibility that mold could form if the environment is too moist. Certain types of mold can be hazardous, especially to those with certain pre-existing health conditions.

Drum: Equipped with a sponge that soaks up water that has been deposited into a tray. Air is then blown through the sponge to create higher humidity levels. The sponge and tray could grow mold if not cleaned regularly.

 

Flow-through: These cost more than drum types, but eliminate mold worries. Water is drawn in and allowed to trickle slowly into an panel made of aluminum. Air will then blow through this panel and out into the home. Excess water is not stored because an included drain tube does away with it.

Central humidifiers are not for everyone, but for those who need them they can provide many benefits. Installation should be done by a professional. Routine maintenance will help reduce the risk of experiencing any problems.
