Which one is better for cold mist humidifier or warm mist humidifier
For safety, always use a cool mist humidifier on children. If you use a warm mist humidifier or steam vaporizer, your child could get burned by the hot water or steam when they get too close. Spills of hot water can also cause burns.
A humidifier increases air humidity. A cool-mist humidifier may help relieve coughs and nasal congestion caused by colds. But more research is needed on this. Some studies have found that heated humidifiers do not help cold symptoms.
Warm mist humidifiers and cool mist humidifiers are equally effective at increasing air humidity. When the water vapor reaches the child's lower airway, the temperature is the same whether it is warm or cool when it is ejected.
When using a humidifier, be sure to clean it to prevent mineral build-up and the growth of bacteria and mold. Humidifiers that use standing water, especially cool mist humidifiers, can disperse such substances into the air. Warm mist humidifiers typically put fewer of these substances into the air, if any.
Draining the water tank and drying all surfaces of the humidifier daily is a safe way to keep your humidifier clean. Also, consider filling your humidifier with bottled water labeled "distilled" or "purified," both of which contain less minerals than most tap water.
