Humidity can cause a variety of problems in your home, whether you have an excess of it or not quite enough. While a humidifier can add moisture to the air in a room, it can also take up a lot of space. If that's a concern for your household, or you want to purify the air wherever you roam, a portable humidifier may be the best solution.

The Best Portable Humidifiers

To say that portable humidifiers come in all shapes and sizes would be an understatement. The best portable humidifier could come in the form of a soda can or take on a more traditional form factor that’s considerably larger. Regardless of the overall dimensions, the one thing every system on our list has in common is the fact they are light and extremely portable when not in use.

#1 MOVTIP Portable Mini Humidifier


MOVTIP is a name that won’t be familiar to most consumers as this small company only makes a handful of products. Several are humidifiers, however, including this highly-rated miniature machine that’s perfect for a bedside table.

This stylish system is less than 6” tall and weighs less than a pound unfilled. That’s impressive, considering it holds 500ml of water, which is double the capacity of many other portable humidifiers. MOVTIP’s humidifier has an extended runtime of 18 hours if you use intermittent mode or 12 hours with continuous usage.

Standard features on this humidifier include an automatic off feature and a nightlight. The former activates once the water level in your system drops below a certain point, and the night light emits a soothing glow while you slumber. This small humidifier is easy to use and can be powered by any standard USB port.

The MOVTIP portable mini humidifier is essentially a larger version of Epoch’s system from a technological standpoint. It has a different design and double the capacity, but still sports the same basic set of features. It's better suited for larger areas, however, and is available in six different colors, including Blue, Green, and Pink.

Pros: 500ml water tank with a runtime of up to 18 hours. USB powered with a night light feature and automatic shutoff.

Cons: None.

#2 BONECO Travel Humidifier U7146


BONECO is a European brand that’s been in business for over 50 years. While their products aren’t as prevalent in the United States, several of their devices have made the jump. The BONECO U7146 is one of them, and it’s made to work with any ordinary plastic bottle.

BONECO designed this ultrasonic humidifier with ease of use in mind. While it doesn’t look like much, it has a visual reminder system that uses colored lights to let you know when the machine is running, or the tank is dry. Automatic shutoff is included as well. It certainly won’t take up much space on a desktop and is quiet with a decibel rating of 32dB.

While small, the U7146 can handle a room up to 215 square feet. The output is respectable and varies depending on the size of the water bottle you use. An adapter makes using any standard soda or plastic water bottle simple. Other features to note on this portable humidifier include automatic shutoff and variable mist control.

The BONECO U7146 isn’t as sleek as some of the other humidifiers from the company, but it’s quite capable despite its size considering it can humidify a small room. It performs as advertised, although you can’t turn off the LED lighting, which may rule it out for some. This humidifier has a 1-year warranty and comes with a travel bag and cleaning brush.

Pros: Pocket-sized system with variable mist output. Works with plastic bottles and can add moisture to rooms up to 215 square feet.

Cons: Can’t turn the lights off.

#3 Pure Enrichment MistAire Eva Humidifier

Pure Enrichment Eva

Pure Enrichment is a brand that specializes in air care products along with personal wellness devices that can help with everything from minor pain to sleep and relaxation. While they have a dozen humidifiers in their catalog, the Mistaire Eva is a fan favorite.

At a little over 13” high and 10” in diameter, the Eva is small enough to tote around, although larger than other systems on our list. That’s because it’s rated to humidify an area up to 500 square feet, and can run for up to 25 hours depending on the settings. It’s also quiet and very efficient, considering the water tank is only 0.73 gallons in size.

This humidifier has a timer that can be set for 2, 4, or 8 hours. It has four speeds and two modes as well. Sleep mode turns off the lights, while the night light feature allows you to pick a hue from seven different colors. Another advantage is the unique filtration system. It has an antimicrobial filter that makes the system easier to maintain while helping to prevent bacteria and mold.

While a bit expensive and large compared to our other picks, this highly-rated humidifier is reliable and has a nice array of features. The detachable power cord with a USB end is a nice touch, and it has a considerably longer warranty than similar systems as well at 5 years. The Pure Enrichment Eva should be high on your shopping list if you’re in the market for a larger, portable humidifier.

Pros: Solid set of features, including multiple speeds, night light, timer, and sleep mode. Capable of running up to 25 hours and comes with an excellent 5-year guarantee.

Cons: It’s larger than other portable systems.

#4 Crane Personal Travel Humidifier EE-5950

Crane EE-5950

Crane has a number of humidifiers, whether you need a warm mist system for a medium room or something a bit smaller. The Crane EE-5950 comes from the company’s Personal humidifier collection, and it’s a unique alternative to a traditional system.

This is a tank-less personal humidifier in the ultrasonic class. Instead of using a tank that’s attached to the system, the EE-5950 will work with almost any container that can hold water. The design allows you to place it into a cup where it will draw water and can produce enough moisture to run for 8-10 hours. It’s not chargeable but is USB powered, which allows you to use it in vehicles or other small areas.

Crane’s tiny travel humidifier is BPA-free and made from antimicrobial material that will help keep bacteria and mold at bay.  There are no features to speak off aside from an automatic shutoff feature, as this is a single-speed system. The EE-5950 measures around 7” long and is 3” wide with a weight of less than a half-pound without the accessories.

As mentioned, you can use the Crane EE-5950 with any cup, but it comes with an 8-ounce travel cup for convenience. You’ll also get three replacement wicks for this system to go along with a carrying bag and USB adapter. The only downside to this system are reports of poor quality control, which is typical for cup-based humidifiers.

Pros: Can be used with any 8-ounce cup or larger. USB powered, and a runtime between 8 – 10 hours. Travel bag and extra filters.

Cons: Some quality control issues.

#5 Epoch Making Mini Portable Humidifier

Epoch Making

When you’re looking for a USB powered humidifier that’s self-contained and quiet, your options are limited. Epoch Making has one of the better systems in that class, and their miniature humidifier is small enough to be used in an automobile.

This ultrasonic humidifier is only 5.6” tall and around 3” in diameter. With a weight of 7 ounces, it’s light and small enough to store in a purse, backpack, or your glove box. As it’s USB powered, you can use it anywhere with a port, which means laptops and power banks are options along with the USB ports found in vehicles.

While you won’t find a room rating for this travel humidifier, it has two modes or speeds. The humidifier can run continuously, which provides 9 hours of runtime or up to 16 hours in intermittent mode. It can hold 200ml of water and has a tight seal so that leakage won’t be a concern. As a bonus, the Epoch Making humidifier also has a seven color nightlight with adjustable hues.

This mini humidifier is one of the smaller humidifiers on the market, but quite useful in small areas. It’s an ideal choice for the car or the desktop in your office and is quite stylish as well. The Epoch Making humidifier is available in Black or White. 

Pros: USB powered with a weight of only weighs 7 ounces. Two modes, a built-in night light, and a runtime up to 16 hours.

Cons: Nothing significant.

#6 HoMedics Personal Ultrasonic Humidifier HUM-CM10

HoMedics HUM-CM10

HoMedics is a brand we touch on often as they have an excellent array of air purifiers and humidifiers. While we’re fans of the company’s larger systems, the HUM-CM10 Personal Humidifier is an interesting option geared towards small spaces.

With a two-tone design and curvy nature, this small humidifier sets itself apart from other portable humidifiers on our list. The design allows it to go with any décor, and it’s still small enough to easily fit onto a desktop. Like many personal humidifiers, the HUM-CM10 can be charged from a USB outlet, but this model also comes with an AC adapter.

You won’t find many features on this simple system, so there’s no night light or timers. It has a 200ml water reservoir and a runtime of 4 hours. The HoMedics HUM-CM10 also has a single mist setting and an automatic shutoff feature. There’s only one button on this machine, so it’s incredibly easy to use as well.

While the HUM-CM10 is easy on the eyes and simple to use, it’s not quite as powerful as other portable systems. What it lacks in power, it makes up in style, and we like the fact it comes with dual power adapters as well. This humidifier has a standard 1-year warranty from HoMedics.

Pros: Nice price point. Easy to use and comes with two power adapters.

Cons: Only one speed, short runtime of 4 hours.

How to find the Best Portable Humidifier 

Portable humidifiers are a dime-a-dozen, and most carry very attractive price tags. While our team went through hundreds of portable humidifier reviews to find our picks, there are only a hanful of areas you need to consider when shopping for a portable system.

Portable Humidifier Pros and Cons

There are pros and cons with any type of the humidifier, but things are different when you drop down to smaller sizes. Here are a few things pros and cons to consider when you’re thinking about purchasing a portable humidifier.

Portable Humidifier Pros

Size can be a double-edged sword with humidifiers, but it's a huge advantage with portable systems and the main draw. You can find humidifiers with unique designs and interesting form factors in this class.

That includes machines you can side into a cupholder or even drop into a cup of water. We also found that most of these small humidifiers are very easy to clean and maintain compared to larger systems.

Portable Humidifier Cons

Whenever you downsize a product, you tend to lose a few features. That's the case with even the best portable humidifier, so you won't find a lot of bells and whistles on these small machines.

Warranties on portable humidifiers are generally short or even non-existent in some cases. Coverage is another con, but an obvious one considering a small, portable humidifier can only cover small areas.


Do you plan to use your portable humidifier on the go or in various rooms throughout your home? While every system we choose is portable, how they are powdered is something consumers tend to overlook.

Aside from a few oddballs, there are two ways these small humidifiers are powered. USB cables are common in this class, and most systems that use one have an adapter for an outlet as well. Hardwired humidifiers aren't as versatile, but still an option and usually a little cheaper.

As for battery-powered humidifiers, they do exist in this class. They are gimmicky, however, and don't measure up to the systems in our list in terms of reliability or performance. USB powered systems are the best choice for portable humidifiers, in our opinion.


As mentioned, one of the drawbacks of purchasing a portable humidifier is capacity. Small humidifiers can only hold so much water, which limits the runtime. That means you need to think about how long you need the humidifier to run for unless you plan on frequent refills.

On average, you can expect between 4 – 6 hours per fill from a small portable humidifier. Medium systems can get you through the night with a runtime of 8 hours or more. Keep in mind that the output setting will affect the runtime as well. While you may get 8 hours on low, high speed will cut the time considerably.


You won’t find a wealth of features when dealing with miniature humidifiers, that's just a fact, unfortunately. Size limits how much tech a company can pack into a portable humidifier. That means the most common or standard feature is automatic shutoff, and everything else is a bonus.

There are a few systems with variable speeds or notification lights for the water tank. You'll also find several minis with a built-in night light feature. While you should still keep an eye out for useful features, reliability is more of a concern in this range.

Portable Humidifier FAQ

A: Unless your water is free of minerals, distilled water is the best choice for use in humidifier systems.

Q: Is a cool or warm mist humidifier better?

A: Cool mist systems can freshen up rooms on hot summer days, while warm mist humidifiers can add some heat to a room in winter. Both serve the same purpose, so it’s a matter of preference and need. If you’re not sure which system is the right fit, our humidifier type guide can help you find the perfect style.

Q: What is the ideal humidity level indoors?

A: It depends on several factors, but a range between 30% to 50% is highly recommended.

A: Manufacturers may have their own recommendations, but you should always remove any filters and ensure the unit is clean and completely dry before putting it away.
