Cold humidifiers are popular among parents. The more common name for these is cool mist humidifiers. When looking to purchase a cold humidifier there are three types to consider.
The first is an ultrasonic humidifier. This machine creates cool mist by the means of vibrations. This humidifier is not very popular because it leaves behind white. The next is an evaporative humidifier. It works by transmitting moisture into the air by fan. Finally, and most common, is the impeller humidifier. The impeller humidifier flings water at a diffuser breaking the water into fine droplets that enter the air.
Cold humidifiers are sometimes more popular than warm mist humidifiers because they are safer to use with children. At times the warm steam let off by warm mist humidifiers burns a child. If a child puts his or her face or hands near a cool mist humidifier, the cool mist will not harm them.
Not only is it safer to use with children, but it is energy efficient. Whereas a warm mist humidifier uses energy to boil and send out the steam, cold humidifiers only use electricity to fan the water.
There is one major danger with the cold humidifiers. Due to the lack of heat, the water in the tank is susceptible to breeding dangerous bacteria.
The Consumer Product Safety Commission found that ultrasonic and impeller humidifiers can dispense harmful microorganisms and minerals into the air. If breathed in, these bacteria may cause serious lung infections.
To prevent any dangers be sure to clean your cold humidifier as suggested by the manufacturer. Most machines require simply cleaning procedures. A good tips to follow is clean your tank every day with soap and water. Empty the tank and fill with a small amount of soap and water. Wash the entire tank, rinse and refill for use.
Be sure to use only distilled water in the tank. Tap water contains certain minerals that need to be filtered out. Unfortunately cold humidifiers do not filter the minerals from the water because they lack heat. The minerals can also lead to breathing problems.
Cold humidifiers should only be used when needed. Too much moisture can cause problems. A good way to monitor your home’s moisture is to purchase a hygrometer at your local hardware store. Ideally your home should be at 30-50%, 60% or higher can result in the growth of mildew, mold and fungi.
