Humidifiers are designed to help us cope well when the air is dry and help us live a more comfortable and healthier life. When the water vapor in the air isn’t enough, the air becomes dry, and this can have an adverse effect on our daily functioning.

Using a cool-mist filterless humidifier will not only save your money and effort but help you overcome the health issues and discomfort that may arise from dry air.

Cool mist humidifiers without filter generate moisture into the environment without the use of heat, and as a result, they do not need electricity to heat the water. Instead, these types of humidifiers only create warm steam.

Getting the best cool mist humidifier without a filter is vital, and we considered many features before coming up with our list. We considered the following features before picking the best products out of many.

Best Cool Mist Humidifier Without Filter: Buyer’s Guide

You might have already thought of getting a cool mist filterless humidifier, but you need to be sure of getting the best one. Look out for the following features and functions to get the perfect cool most humidifier without a filter for your home.

 Water tank capacity

The amount of water a humidifier’s water tank can hold usually determines the runtime and the amount of moisture you get. Many cool mist humidifiers can hold up to 2 gallons of water and below.

 Coverage area

Generally, every humidifier comes with a specific figure of the coverage area that the humidifier can humidify and this is usually measured in square feet. So, the size of your room or entire home should be taken into cognizance before you settle for any humidifier of your choice. However, note that the best way to know the actual coverage area that a humidifier can humidify is to read other people’s reviews.

Sound level

Some humidifiers can be noisy, but most humidifiers without a filter are noiseless, and this is one of its advantages. If you have little ones or find it difficult to sleep well in a noisy environment, you should choose a very silent humidifier. 


Another significant feature to consider before purchasing your humidifier is the number of hours it takes to run out. The runtime is essential because it determines how long or how often you refill the tank. Some humidifiers do come in a different setting, but the low setting is the best as it helps you save the amount of time you spend refilling the tank. 

Essential oils compatibility

The essential oils in your humidifier provide you with many benefits, such as helping you to sleep better and soothing your cold. Essential oils also help your home to smell nice.

 Mist type 

The mist type is another vital feature to watch out for. Cool mist does not heat your room but releases moisture at warm temperatures. Warm mist, on the other hand, will heat your room and kill the bacteria in the water, helping you to increase humidity and as well provide a safe environment for you.

Remote control

For ease of you, some humidifiers come with a remote control to prevent you from getting up every time to adjust your settings. Since humidity levels change from time to time, you can control the humidity in your room by using a remote control. You can also turn it off or on at any time 

Size and Weight

Another important factor to consider is the size and weight of the humidifier. If you’re getting a humidifier for the whole house, you have to go for larger humidifiers. If you’re using it in a small space, you’ll have to go for the portable option. So, be sure of the best size for your space.


Getting a humidifier with a good warranty will give you peace of mind because you know you’ve got yourself an excellent product. If a manufacturer can provide you with a few years of warranty and another offers only a few months, going for the former becomes the ideal thing to do. This is a vital feature you shouldn’t miss to prevent future problems
