Both cool mist and warm mist humidifiers will add needed moisture to any environment. The main difference between a cool humidifier and a warm humidifier is the type of mist that is released. Both cool and warm humidifiers have pros and cons that should be weighed prior to purchase.

Cool Mist Humidifiers

Generally, cool mist humidifiers trap air particles with the help of a filter. Once impurities have been trapped, a cool humidifier will release a cold mist into the air. Cool mist humidifiers include evaporative, impeller and ultrasonic models.

Here are some reasons why you may want to consider a cool mist humidifier:

Cool air can be easier to breathe.
Cool mists are refreshing.
Cool mist filters are easy to clean.

Some people prefer a warm mist humidifier based upon these cool mist cons:

Cool mist humidifiers can be noisy depending upon the model chosen.
The mist release by a cool humidifier can feel damp to some people.
Mold can grow inside of these humidifiers if they are not cleaned properly.

Warm Mist Humidifiers

As with cool mist humidifiers, warm mist humidifiers also add a good amount of humidity to the air inside of a home. Warm mist humidifiers include vaporizer and steam models. Here are some of the reasons why many people prefer warm mist humidifiers:

Some models include a medicine holder.
Warm mist humidifiers help to clear up congestion due to cold and flu.
These humidifiers tend to be quieter than cool mist machines.
Warm mist adds warmth to rooms during cooler months.

Warm mist humidifier cons include:

Warm mists can make a room feel damp.
Steam that is too hot can be a hazard – it is important to keep children away from these machines.
Warm mist humidifiers do not add moisture to large rooms efficiently (these humidifiers are best reserved for smaller spaces).

How to Choose a Humidifier

Choosing between a cool mist humidifier and a warm mist humidifier is largely a matter of personal choice. If the thought of a cool mist entering your air space seems like a refreshing idea, then you may want to consider a cool mist humidifier. Also, think about purchasing cool mist humidifier if you want to add humidity to a large space, since these machines are best suited to wide open spaces.

Warm mist humidifiers are an excellent choice if you live in a cooler climate. A warm mist will provide needed warmth while also allowing you to combat any kind of cold, flu, or allergen. Carefully considering the pros and cons of each type of humidifier is a wise idea. Think about the climate you live in, how big your home is, and the type of mist that seems to suit your needs best prior to purchasing any humidifier.
