The low level of humidity will often worsen the symptoms of asthma. Cool mist humidifiers have a filter which traps minerals and impurities in the air releasing a cool, invisible mist that evaporates into the air. Additionally, with this unit there is no danger of burning, which is very important if you have children in the house or any older member of the family. Here are the three types:

Impeller

This type of cool mist humidifiers creates the mist by a spinning disk. However, this process of creating humidity is not so noisy as the one created with a fan. Furthermore, impeller humidifiers are easily movable from one place to the other. And the best thing is that they use less electricity in comparison with warm mist humidifiers which have some heating elements.

Evaporation Wick

This kind of humidifier first absorbs water with a wick, and then evaporates it by a fan. In fact, this way the evaporation comes is natural way, which is considered to be an additional advantage. Still, some people would be bothered with the noise coming from the fan, while others find this sound great for their sleep. On the other hand, the evaporation rate will slow when the humidity in the air increases thus making these units, in fact, self-regulating.

Ultrasonic

More modern type of a cool mist humidifier is the ultrasonic model. It creates a mist through sound waves that vibrate the water. It is, in most cases equipped with a demineralization filter which will trap minerals before they are released into the air. Besides, some models contain a heating option.

In the main, it is necessary to know that cool mist humidifiers should use distilled water so as to prevent the build up of crusty mineral deposits or scale, as this can be a breeding ground for mold and mildew.

In brief, you will certainly get a very helpful device in your home if you provide a cool mist humidifier, as it is a sure way to keep away from the being infected by germs, mostly during the flu season.
