Types of Humidifiers

On the market there are available various types of humidifiers, each with advantages and disadvantages. Remember the final choice when looking for the best humidifier for baby must be based on its performance.

Warm mist humidifiers are generally cheaper than cold mist ones but these humidifiers can be dangerous for babies as they can get burned if they accidentally touch the device. For this precise reason doctors recommend cool mist humidifiers.

Cool mist humidifiers are most recommended for infants and young children, but they also present some disadvantages. Because the water doesn’t reach the boiling point, these devices can be an ideal place for the growth of mold and bacteria. The inhalation of this bacteria by the baby can result in respiratory problems and for this reason, the device must be properly cleaned with vinegar or chloride on a daily basis. In this category a difference must be made between ultrasonic humidifiers, which produce a thin mist of water vapors using ultrasonic sound vibration and the ones which use a vent system.

Finally there are available evaporative humidifiers. These devices use a fan system which blows the vapors through a filter. Although the filter collects most impurities found in the air, these devices can sometimes be noisy.

If you choose a cool mist humidifier for the nursery consider using distilled water rather that tap water to avoid the spreading of mold, bacteria and minerals from water into the air.

How to Choose the Best Humidifier

As you’ve seen, cool mist humidifiers are the most recommended, but the choice isn’t as simple as it might seem. In order to make a high-quality purchase you should make sure the humidifier meets a few important characteristics. Here is what to look for when deciding which humidifier is the best for your needs.

  • Covered area. Consider the area of the nursery before purchasing a humidifier to avoid getting a device that is too big or too small compared with the room’s dimension. In the first case the excess humidity will create a suitable environment for mold and fungus growth; in the second the device will not provide enough moisture.
  • Noise level. A noisy device will most likely interfere with the baby’s sleep. Ultrasonic humidifiers are almost silent, but pay attention to choose a device that maintains a low level of noise on any setting.
  • Water tank capacity. It is desirable to have a large enough water tank to allow the proper functioning of the device for about 12 hours. This way you won’t have to refill the tank during baby’s sleeping time.
  • Air ionization function. This is an often overlooked aspect when choosing a humidifier, but a device with this feature significantly reduces the amount of dust from the room.
  • Protection system. This is a very important feature. The protection system will turn off the device if it runs out of water. It generally also emits an acoustic or visual signal that will let you know it’s time to refill.
  • Auto shut-off. A performant humidifier must definitely have this function which automatically shuts off the device when the desired level of humidity is reached. This will help you maintain a constant level of moisture in the air and will also help you save on electricity.
  • Removable water tank. This is an important characteristic for both easy cleaning and easy refilling of the reservoir.
  • Antibacterial features. Although this is not an essential aspect in warm mist humidifiers, you may want these features in a cool mist humidifier. There are various options, like ultraviolet lights,filters or cartridges to keep the bacterial level at a minimum.
  • Difusser function. Although this is not essential, this can be a very useful feature if the baby has a restless sleep. Using an essential oil you can create a calmer environment for your child.
  • Weight. Low weight humidifiers are a better option than heavy ones, as you can place them anywhere in the room. A light humidifier is also great if you plan on taking it with you while traveling. However, because the weight is also related to the complexity of the device, this is the last feature to consider when choosing the best humidifier for your baby.

Keep in mind that you need to find a humidifier that fully matches your needs, so before making a purchase try to find out as much as possible about the features and functions of the device you’re interested in. To help you make a final decision, we list below the best humidifiers for baby.
