When to Use a Warm Mist Humidifier
Humidifiers are electric devices for improving the moisture content of air. They work well to relieve dry sinuses and other uncomfortable conditions caused by dryness. Humidifiers also keep static electricity levels low, reduce wallpaper peeling and prevent cracking of wood furniture. Humidifiers come in two major types: warm mist and cool mist. Each one is appropriate for certain uses. Does this Spark an idea?

Function
-
Cool mist humidifiers may be ultrasonic, using vibrations to create mist; impeller type, which use a high-speed dish to throw water into the air; or evaporative, which blow air through a filter or wick. Warm mist humidifiers, also known as vaporizers, usually heat water using an electrode or an electric heating element. Models that cool the steam slightly before it exits the humidifier produce a slightly warm mist. Models that do not cool the steam produce significantly hotter streams of water vapor.
Minerals
-
According to the United States Environmental Protection Agency, steam vaporizers disperse fewer minerals into the air than ultrasonic or evaporative humidifiers. These minerals, including calcium, iron and manganese, naturally occur in tap water and may produce dust or mineral scale on surfaces around the humidifier. A warm mist humidifier is a good choice for people who wish to avoid this problem. Because the minerals stay in the water, the humidifier may need periodic cleaning with vinegar or another demineralizing cleanser to remove built-up deposits.

Safety
-
Warm mist humidifiers can be a safety risk for homes with small children and pets, especially if you use a model that doesn't cool the steam. Some humidifiers emit steam that's hot enough to cause discomfort or minor burns. The heating element may also cause the humidifier itself to become hot, and hot water inside the humidifier could burn or cause damage if spilled. Place warm mist vaporizers out of reach of kids and pets, or use a cool mist humidifier instead.
Misconceptions
-
Many people believe that warm mist humidifiers are better for colds and coughs, due to the soothing nature of warm air. However, according to MayoClinic.com, water vapor from both warm and cool mist humidifiers is the same temperature once it reaches the lower airways. Warm mist humidifiers provide no significant cold treatment benefits over cool mist models.
Warning
-
While humidifiers help improve breathing in people with minor respiratory problems, they can make the situation worse if you have allergies or asthma. According to MayoClinic.com, increased humidity does help some asthma and allergy sufferers, but it also encourages an increase in allergens in the home. If the water is dirty or contaminated, it may also trigger an asthma or allergy attack.
