Lack of adequate air moisture is a common phenomenon during the winter season. Heating up your home during this season only worsens the problem by making air dryer. Dry air does harm your respiratory system and is likely to worsen any existing medical conditions. It dries out your nasal passage as well as your skin. In addition, it causes thirst and coughing fits soon after waking up. Furthermore, dry air also damages your furniture. Given all these problems, it would be prudent for you to invest in the best warm mist humidifier.

There are three types of humidifiers available. These include warm mist humidifiers, cool mist humidifiers and ultrasonic humidifiers. Ultrasonic humidifiers feature both cool and warm mist types. Cool mist humidifiers disperse cold mist into the air at room temperature to increase the humidity level in your home. Here, we are going to provide a comprehensive round up and leave it up to you to select the best warm mist humidifier of your choice.

Benefits of Warm Mist Humidifiers

Warm mist humidifiers work by releasing moisture-filled mist after warming or boiling water using a heating element. Some benefits that come with warm mist humidifiers include:

  • It is the healthiest option since it kills germs during the heating process
  • Warm mist humidifiers are capable to collect minerals that may be left over after heating water
  • Filters of these devices rarely need replacement
  • Warm mist humidifiers work well during the cold season as they can raise the temperature a bit
  • They are the perfect choice for office or bedroom settings since they produce minimal noise
  • They are applicable in the medical field for example in aromatherapy
  • Warm humidifiers come in small compact sizes making them portable 

If you have children, it would be best to use cool mist humidifiers instead. This option is much safer because children may burn if they touch warm humidifiers. Also, it is safe to sleep with your humidifier on regardless of whether it is the warm or cool version. Doing so makes you sleep better as it improves the quality of air in your room.

What To Look For When Buying A Humidifier

While there are many humidifier brands and models out there, all aren’t created equal:

Type of humidifier

There are many different types of humidifiers in the market nowadays. While each propels moist air into your home, they do it quite differently. You must understand how these units work before you choose one. They include impeller, ultrasonic, evaporative, and warm mist humidifiers.

Warm mist or cool mist

Warm mist humidifiers are best for those who have flu or cold. They are also the ideal type of humidifier for asthmatics since they boil water killing germs in the process before releasing warm mist. Warm mist humidifiers are also ideal during the winter. On the other hand, cool mist humidifiers are easier to clean and have a high moisture output.

Germicidal measures

Standing water can breed mold and bacteria which can be inhaled when released into the air. Your ideal humidifier should have a filter to prevent possible health hazards from dispersed germs and bacteria.


Do you need multiple room humidifiers or a whole house humidifier? Your choice should depend on the size of your house and the budget since humidifiers are only meant for rooms people use frequently.


Some humidifiers have a large water capacity than others. The larger the capacity the less frequently you will have to refill it. However, a bigger capacity also means more space and more difficulty in maintenance.
