Cool Mist Humidifier vs. Warm Mist Humidifier

A humidifier is used to alleviate discomfort caused by dry skin, allergies, asthma and stuffy sinuses by increasing the moisture content (humidity) in the air. A warm mist humidifier heats water to produce steam that humidifies the air. A cool mist humidifier releases tiny water droplets into the air.

edit Humidity levels

Humidifiers are required to maintain the moisture content of a room. 35 to 50% humidity level is considered to be healthy. A low humidity level results in dry and itchy skin or chapped lips. Humidity level greater than 50% results in growth of mold spores, bacteria and dust mites. 40% humidity is required for musical instruments to prevent their crazing or cracking of finish.

edit Optmimum humidity level for the flu virus

The flu virus thrives best when humidity is either over 98% or between zero and 50%. So Dr. Linsey Marr, a researcher at Virginia Tech, recommends keeping humidity levels around 50% (but not over 60%, because that can cause mold buildup) to give the flu virus the least chance of survival.[1]
