Breathing easy is one of the best ways to relax irrespective of where you are. When you travel or are confined in a small space, you will often find the air to be too dry. This can make it difficult for you to inhale and exhale. Moreover, it can make your throat itchy. A travel humidifier is responsible for restoring moisture to the direct air surrounding you so that you do not have any breathing problems.
Finding the best travel humidifier for yourself can be an ordeal because of the multitudes of choices on the market. However, we have chosen seven models for you on this list, which we liked most. The MADETEC Cool Mist Ultrasonic Humidifier emerged as our Editors’ Choice because it combines all the features that you might need. Lightweight and efficient, it will give you a run-time of up to 10 hours. It also comes with a 7-color LED light that you can use as a night light if you wish. Having said that, all the travel humidifiers we picked come with their own advantages, and you should check all of them out before coming to a decision.
When choosing a small humidifier, it is important to consider the size and weight of the model to determine portability. You should go for a type that suits your needs and is easy to use. Different humidifiers have to be charged differently, so you have to be mindful of that too and check if you need to keep them plugged in while using them. We have created a table listing all the products and then reviewed them in detail. There is a buying guide at the end to help you out.

Things to Consider
Choosing the perfect model for yourself will ultimately come down to your personal requirements. We have created this buying guide so that you do not have any trouble judging the humidifiers and their value.
Type: are all travel humidifiers cold mist?
Most of the travel humidifiers we have selected release a cold mist so that the dry air can become cool and adequately moist. For example, the Fancii Cool Mist Personal Humidifier gives out light and cooling mist. However, you will also find warm humidifiers on the market. If you want a product that will give you the best of both worlds, you can go for the Pure Enrichment MistAire Travel which heats up the water after a while and releases a warm mist.
Bottle and non-bottle humidifiers
There are different types of humidifiers available on the market, and you will have to choose the kind that works best for your needs. Some humidifiers come with a bottle that is tailor-made for them. You will have to use that particular bottle when you want the machine to work. On the other hand, there are some humidifiers like the Hunter QLS03-WT that can accommodate all standard water bottles. This is convenient because you will just have to carry the humidifier when you are traveling. There are some humidifiers like the JAYWAYNE Portable Mini Humidifier that are compatible with glasses, mugs, and bottles.
Portability: size and weight of a travel humidifier
When it comes to a travel humidifier, you cannot discount the importance of portability. You will have to take the size and weight of the model into account in order to understand how portable it will be. Make sure that you can carry it in your bag without any problem. Humidifiers like the MADETEC Cool Mist Ultrasonic Humidifier and the Fancii Cool Mist Personal Humidifier have a compact design and are perfect for travelers. Portable humidifiers are also lightweight, so they do not weigh down your bag or luggage.
The way to charge your travel humidifier
You must take care of your humidifier if you want it to last for a long time. Charge it regularly using the recommended means. Most of the models on the list are either powered by USB, but there are other options as well, powered by batteries or through AC adaptors.
Humidifier runtime
You need to take into consideration how long you want your humidifier to work. Humidifiers do not come with a standard run-time. It differs from model to model depending on the capacity and the design. If you feel that your humidifier needs to work overnight, then you should go for models that have a longer runtime. The Figrol USB Portable Mini Humidifier can give you 24 hours of runtime off 1 liter of water.
The area it can cover
When you are buying a travel humidifier, it is important that you get an estimate of the area it needs to cover before making a choice. For example, if you want to cover a large area, then getting a humidifier with a small capacity is a bad idea. You will need a model like the JAYWAYNE Portable Mini Humidifier that puts out plenty of mist over a long period of time and can cover an entire room. On the other hand, if you want a humidifier for a small hotel room, you can settle for models like the Figrol USB Portable Mini Humidifier that are not as powerful.
Noise level
You should not feel disturbed when the travel humidifier is running. If the humidifier is switched on for long periods of time and makes noise constantly, then you will get frustrated after a while. You will not be able to use it at night either because the noise will not allow you to sleep. Models like the Fancii and MADETEC humidifier run very quietly and do not make any sound to disturb you. They use advanced technologies that cut down on the sound when the machine is working.
In fact, most of the models on our list will give you a noise-free experience.
Warranty
All travel humidifiers must come with a warranty period so that you can build faith in the manufacturer. You can gauge a company’s faith in its products by the warranty they offer. The Pure Enrichment MistAire Travel humidifier comes with a 5-year warranty, which is the longest on our list and probably the longest available for such a small and affordable unit.
Extra features
Travel humidifiers are much more advanced now, and you should keep an eye out for extra features that will make them more convenient to use. The auto shut-off feature is a must because it increases the safety of the machine. The humidifier will automatically shut off after the water is over.
You should also check if the humidifier has filters that will ensure that the water being dispersed is clean.
Most recent models also come with timers so you can adjust the runtime as you wish. You might also in-built lights helpful because they will allow you to see in the dark and also act as night lights. The MADETEC Cool Mist Ultrasonic Humidifier encompasses all these features.
Cool mist humidifiers release cold water vapor into the air surrounding you so as to make it moist and breathable. Cool mist humidifiers usually run on one of two distinct mechanisms. The first method consists of the evaporative wick that pulls in the water and fan that then makes it evaporate. The second method utilizes ultrasonic technology. Ultrasonic vibrations are sent through the water, breaking it into very small particles that are then released into the air.
No. It is absolutely not recommended to put any essential oil in your humidifier if it wasn’t designed for it. Adding essential oils might cause cracks in the tank, and make the humidifier malfunction.
