Best Cool Mist Humidifiers

In areas of high humidity, it is often the case that humidifiers are often used to improve the atmosphere in your home (and maybe where you work). In winter months and in countries where it is generally much colder on a day-to-day basis, households are likely to use more of their heating. As a result, your humidity can plummet exponentially.

With the use of a high-quality humidifier, you can ensure your indoor air has more moisture and feels less dry, even in colder weather or areas that are naturally cold. Furthermore, while humidifiers are used in colder temperatures, they are also commonly used during the less cold seasons.

But how do you decide what type of humidifier to buy? There are plenty of makes and models of humidifiers available on the market. This can make searching for the right humidifiers more complex and more irritating.

Humidifiers come in 3 different types: dual mist, warm mist, and cool mist. Warm mist humidifiers help your room to feel nice, warm, and comfy. In contrast, cool mist dehumidifiers provide a cooling effect and relief from humid air through the cool mist.

If you suffer from dry skin or have dry nasal passages, then cool mist humidifiers are sure to help relieve your symptoms with their moisturizing effect on indoor air.

Warm vs Cool Mist Humidifiers in Detail

Warm mist and cool mist humidifiers are very similar. They differ largely because of the process by which they humidify the air. As in the name, warm mist humidifiers use the power of heat to boil water and thus creates steam that has a warming effect on the indoor air.

On the other hand, cool mist humidifiers use a fan to let the water evaporate safely and efficiently into your indoor air, thus causing a cooling impact.

Both types of humidifiers have advantages and disadvantages. Since warm mist dehumidifiers use boiling water, it may be dangerous for young children or pets. If the boiling water either leaks or somehow spills over, it may cause burns. It is also likely to require more energy than cool mist humidifiers.

A major advantage of warm mist humidifiers is that it is more effective at getting rid of harmful bacteria due to the boiling water temperature. Without the need for a fan to function, warm mist humidifiers have often been reviewed as being quieter than cool mist humidifiers.

Cool mist humidifiers can often be a brilliant choice. This is because a warm mist humidifier may be too inconvenient in the hot summer months. It is also largely unsuitable for naturally hot areas with very high humidity. Cool mist can also help to alleviate the symptoms of cough or colds.

Unfortunately, an irritating factor when it comes to cool mist humidifiers is that they can quickly accumulate bacteria if it is not cleaned as properly or as frequently as required. Without being actively maintained, it may cause the harmful growth of germs and mold.

Factors To Consider Before Making a Purchase

There are several elements to a good cool mist humidifier. Below is a guide that might be able to help you make a choice more easily:

Type of Cool Mist Humidifier

In general, there are 2 types of cool mist humidifiers: Evaporative Cool Mist Humidifiers and Ultrasonic Cool Mist Humidifiers.

Evaporative Cool Mist Humidifiers

Evaporative Cool Mist Humidifiers use a fan to create their humidifying effects. Air is pushed through a porous wick by a well-built fan. Then, water is absorbed directly into the wick. Afterwards, the air chills as it retails moisture from the wick. Be aware, however, that it is required for you to purchase wicks to replace the current wick for maximum efficiency.

Since this type of humidifier utilizes the power of fans, an unfortunate result is that it can be quite loud.

Ultrasonic Cool Mist Humidifiers

Such humidifiers create a cooling mist through very high-frequency ultrasonic vibrations. These types of humidifiers do not use fans; hence they can be much quieter in comparison to evaporative cool mist humidifiers.

These humidifiers can also be entirely silent, depending on the model. More often than not, they are also lower maintenance since they are less likely to induce the growth of mold and mildew. However, it is still important to make sure that you clean your humidifier at least once a month to ensure good hygiene.

Coverage Area

Basically, coverage area refers to how much square footage a dehumidifier is designed to work in. It depends entirely on the humidifier itself. The type and output capacity are the elements that determine the coverage area.

For those who wish to purchase humidifiers for smaller, more compact places, then certain types are more beneficial than others. For example, either a personal or tabletop humidifier is a good choice for such places.

For those looking to purchase humidifiers for larger and more spacious places, it would be beneficial to purchase a console model. They are advisable in these cases because they tend to create plentiful levels of moist air. These humidifiers also tend to have water tanks with larger capacity, meaning that it’s more convenient.

User-Friendly Design

An important factor for humidifiers is how easy they are to set up, maintain, and use.

Those who aim for convenience will likely benefit from purchasing humidifiers that are compact and portable. Being able to easily move the product means that it is much more efficient to clean, and it will require less time and effort overall. If you choose to purchase a floor model (or even a table model), it should still have good portability.

A user-friendly design also includes how easy it is to maintain and locate part replacements. For those who want to choose an evaporative cool mist humidifier, it is essential to make sure that the model has a wick that is easily accessible and replaceable. It would be irritating if the wick replacements are difficult to purchase or difficult to actually find in a reliable shop.


To find the best cool mist humidifier, you will need to understand the importance and quality of the controls and the user interface that portrays humidity levels. There may also be additional settings included by the manufacturer.

While not all humidifiers are equipped with controllers, the ones that do have controls prove advantageous due to giving you the ability to control the humidity.

There are also quite a few models of humidifiers that do not have humidistats. However, for many people, the presence of a humidistat can be crucial when deciding on a purchase. This is because some products automatically shut down when the air reaches your preferred humidity level.

Humidifiers with humidistats can help save money on both water and electricity. For those who have chosen a humidifier without a humidistat, then it might be prudent to purchase a hygrometer as an alternative.

Hydrometers help to measure the humidity level in your rooms. This can therefore help you understand when the humidifier needs to be shut off. However, this may be more inconvenient as you need to do this manually. You may have to constantly check the hydrometer.


Certain types of humidifiers have a very innovative design that ensures that it is easy for users to refill. Certain designs are also much easier to clean and maintain. There are also humidifiers with more parts, making them harder to maintain and more difficult to clean.

Nonetheless, it is very important to be able to properly clean your humidifier. Follow the instructions accompanied by your purchased product in order to efficiently clean your humidifier.

When it comes to how frequently your humidifier needs cleaning, this depends entirely on how often you decide to use the product. It may require cleaning and drainage on a daily basis. However, it is very important to clean the unit as it could cause the growth of bacteria and germs.

Without cleaning properly, the humidifier could circulate harmful airborne bacteria around your home. The water may be filled with bacteria that could cause detrimental effects on the members of your household.
