Best Travel Humidifiers Review

Fancii Cool Mist Personal Mini Humidifier

This portable humidifier has everything you need and more all packed in a device as compact and light as 3.52 ounces. Instead of a water tank, the Fancii Cool Mist Personal Humidifier uses a standard-sized water bottle (around 500 ml or 16 oz) to moisten the air and improve air quality in your bedroom, car, or even during a long flight. 

It runs for a maximum of eight hours (after which the unit automatically shuts off) or you can set a timer for two, four, or six hours. Its whisper-quiet operation ensures you get quality sleep anywhere you go. The simple, sleek design also earns points for us. 

This tiny beast is powered by three AA batteries which can last up to 18 hours, or plugged to a source through the included USB cable. Also provided when you buy this unit are three cotton filters – each can last one to two months. 

The only drawback is that you need plastic bottles with standard necks, anything else won’t work. And if you want your humidifier to diffuse your favorite essential oils, then Fancii might not be your first choice. Otherwise, you really can’t go wrong with this one.


  • Lightweight, unique design
  • Battery operated
  • Timer function


  • Low durability
  • Requires water bottles

This compact humidifier also comes with colored LED light to help set the mood in your car or bedroom. You can choose between two mist modes – continuous and intermittent. Its 50 ml capacity can last hours depending on the size of the space you want to humidify. It will probably not run as long as some of the models in this list but it does its job just as well.

  • Essential oil diffuser
  • LED light

MovTip Cool Mist Humidifier

Perhaps after a long day of travelling you just want to jump straight to bed and rest. This MovTip mini humidifier does anything but complicate your life.

The built-in water tank can hold up to 500ml, lasting 12 to 18 hours depending on the mist mode. One push gives you continuous mist, a second push, intermittent.

What to Consider when Choosing a Travel Humidifier

With so many options available in the market today, it can be an overwhelming task to choose the best travel humidifier. Luckily, we made the job easier for you. Here are some features you may want to consider before making your choice. 


Depending on the frequency and duration of your trips or how much you’ll be moving around, you may not want to lug a heavy, bulky device with you. Travel humidifiers come in many different sizes and shapes for your convenience. Some of the smallest designs can even fit in the palm of your hand. Those that come without an internal tank may be your first choice if portability is most important to you.

Run time

Smaller capacity typically means shorter run time. Keep in mind that the climate of the place will also play a role in how hard your humidifier needs to work in order to balance the air quality. The dryer it is, the more water you need and the shorter your device can last. If you want a unit that can run overnight, consider getting a humidifier with a larger capacity.


This won’t really matter if you’re only using the humidifier for yourself or in a very small space. However, if you’re staying with several people in the same room or you want it to work in a larger space overnight, you need a device that can handle the job. The bigger the space, the more moisture it requires.

Power source

It can be a hassle to bring cords and adaptors when you’re saving much needed space in your luggage. But if that’s not a problem for you, most travel humidifiers can be plugged into a wall socket or through a USB source. For the adventurous backpackers, you may want to consider getting a battery-powered cool mist humidifier.

User friendliness

Simplicity is key for some of us. If you don’t want to rack your brain trying to operate your humidifier, get one that works as easily as pushing a button. You don’t need to compromise ease for functionality.

Ability to work with essential oils

Some brands are generous enough to offer both a humidifier and a diffuser in a single device. For absolute comfort and relaxation, you may want to look for a humidifier that works with essential oils just as well. Pour a few drops of peppermint or other oils and avoid that nasty seasonal allergy. 

Other features

Most of the models in our list include a nightlight to soothe you or help you navigate in a dark room. You can also find useful additions like the auto shut-off feature and different mist settings. If you’re conscious about your plastic usage, it might be best to get a humidifier with a designated water storage instead of working with plastic water bottles.

Types of Humidifiers

Cool Mist Humidifiers

The most common type is called an evaporative humidifier. It uses a wick filter to absorb water from the reservoir. A fan then blows through the filter, letting the moisture evaporate. They are safe for children and pets. This type of humidifier self-regulates. As humidity levels increase, it becomes more difficult to evaporate water.

An ultrasonic humidifier is best used at night because of its nearly soundless operation. It produces a cool mist using high-frequency vibrating metal diaphragm instead of a fan. Some cool mist humidifiers also work as a diffuser of essential oils.

Warm Mist Humidifiers

A steam humidifier or vaporizer emits warm mist. It has an internal heater that boils water before releasing the warm steam into the air. It can reduce bacterial contamination and dust accumulation. Although, there is an added risk of burns. This type of humidifier is great for cough and cold symptoms.

Can you leave a humidifier on while you sleep?

Yes! Sleeping in a harsh environment with dry air can cause serious harm to your health. All the models we listed have the auto shut-off feature to protect you and the device.

Where should you place your humidifier?

It depends on your power supply but ideally, it must be at least a few feet away from you and above the ground. It should also face open air or moisture will accumulate in one place.


There isn’t one answer to the best travel humidifier. Each individual has a different lifestyle that calls for different needs. We’ve highlighted the best model in each category to help you decide. Whatever you choose, it is always the health and comfort of you and your family that come first.
