Warm mist units boil the water before propelling it into the air, so they are great for lessening germs, but if your child pulls it over, it could be harmful. If your child is not going to get to it, then warm mist units are a better choice overall. Do not confuse these with vaporizers. Those also boil the water, but do not generally have a cooling chamber, so your child could burn herself on the mist. I do not recommend humidifiers uk Vaporizers as a little more money gets you a much better unit if you buy a warm mist humidifier.
Many warm mist units, especially Vicks, have built in medicine cups to hold soothing medicinal vapors. The warm air heats the cup and releases the vapors, such a vicks. This can be really helpful for stuffy noses and colds.
So, which is the humidifier brand? Check out the Crane ultrasonic humidifiers for cool mist. Also, the Air O Swiss has a great unit. Make sure to use distilled water in these so you do not send minerals into the air as these are irritating to lungs. The Crane and Air O Swiss humidifiers get many great reviews from parents.
