Cool Mist vs Warm Mist Humidifier

Cool Mist vs Warm Mist HumidifierHumidifiers have become really popular in the last years. They are particularly beneficial for newborns, their fragile respiratory system requiring a constant level of humidity to be able to develop properly and to avoid colds and sinus irritation. In this case, also temperature plays an important role, that is why it is recommended that you also buy a thermometer and a hygrometer to monitor continuously the air temperature and relative humidity in the room. Some air humidifiers incorporate the two items.

Relative humidity in the room should have a value of 50-60% and without a humidifier it goes even below 40% when using heating sources. One of the most important questions when deciding to buy a humidifier is  whether to choose a cool or warm mist humidifier.Both have advantages and disadvantages that we are going to discuss in the following post.
