Humidifiers are fantastic for helping to soothe common problems caused by dry indoor air, like chapped lips or irritated sinuses. And humidifiers with scents or cool mist can make a room more relaxing. Fortunately, more companies are making portable versions that can be used everywhere, from hotel rooms to cars. But there are a few key details to keep in mind when shopping. Things like size, weight, and scent options are all factors to consider as a traveler. Buyers will also want to know if the humidifier uses a water bottle or water tank. We've done all the research for you and rounded up our top picks. Read on for the best travel humidifiers available. Best Overall: GENIANI Portable Cool Mist Humidifier Courtesy of Amazon Buy on Amazon Buy on Walmart What We Like Easy to operate Two mist modes It fits in a car cup holder What We Don't Like Cleaning is labor-intensive With measurements of just 3.4 x 3.4 x 6 inches, this humidifier can fit wherever your travels take you. Whether in a hotel room or office, the cool mist will instantly enhance the immediate surroundings and make the air more comfortable to breathe. Two mist modes allow you to customize the experience more: The continuous spray mode is excellent for shorter stints during the day, while the intermittent spray allows for a comfortable overnight. Both modes are super quiet, and every function is controlled with one button. And don't worry about knowing when to refill it. A built-in water level sensor will automatically turn off the power when the water is low, so you'll know when to top it off. It will need to be plugged into a wall at all times, but that shouldn't be a problem if you're using it in a hotel. Run Time: Up to eight hours | Power Source: Corded USB | Weight: 8.8 ounces Best Budget: HIETON Mini Desk Humidifier Courtesy of Amazon Buy on Amazon What We Like No water leakage even if tipped to 90 degrees Quiet It can fit in a car cup holder What We Don't Like The portable version shuts off after four hours of use Smaller tank Even though it's small, this humidifier has many customizable options to create the perfect individualized environment. Seven LED lights can rotate, remain steady, or be turned off completely. Two mist modes allow for four hours of continuous spray mode or 10 hours intermittent mist mode. The HIETON Mini can also be used with a scent of your choice; simply add one to three drops of perfume or water-soluble essential oils to make your surroundings even more zen. Plus, it's capable of being plugged into any USB source—even a portable power bank—a major positive while traveling. One of our favorite features is that it can tip to 90 degrees without any water spilling. Oh, and the sleek design means the 200-milliliter water tank design can fit in a cup holder. All of this is available for one of the lowest prices we saw in our research. Run Time: Four to 10 hours | Power Source: Corded USB | Weight: 7.2 ounces The 13 Best Travel Accessories of 2022 Best With Essential Oils: Fioyal Humidifier Courtesy of Amazon Buy on Amazon What We Like Can customize with a favorite scent Easy to clean Mood lighting What We Don't Like Shorter run time Plenty of people enjoy the soothing scent capability that comes with many full-sized humidifiers. Fortunately, some manufacturers added that feature to travel versions. With the Fioyal humidifier, just add two to three drops of your favorite oil via the essential oil tray, and you'll be on your way to a more stress-free hotel room or car ride. It has two mist modes—continuous and intermittent—though the run time is only a maximum of eight hours. This humidifier comes in seven colors and is whisper quiet, registering just 19dB compared to the 30dB found in others. And although it has to stay plugged into work, it's compatible with a car, computer, and wall USB port. Ultimately, it's designed to be invigorating when on a long car ride or calming when trying to wind down in a new destination. Run Time: Four to eight hours | Power Source: Corded USB | Weight: 7.4 ounces Best for Road Trips: Luckybay Mini Humidifier Courtesy of Walmart Buy on Walmart What We Like Designed for car use Strong magnetic sealed door Seven color options What We Don't Like Six-hour maximum run time This simple, mini humidifier was designed to make that long road trip a haven on wheels. The 300-milliliter water tank amazingly still fits into a cupholder, making it convenient for the whole car to be enveloped in the relaxing mist. And, depending on the length of your car ride, you can choose from a continuous or intermittent spray with up to six hours of total run time. In addition, there is a colorful light function for a little mood boost and a night-light mode to calm things down during a late-night trip. The company even thought of those pesky water-spilling road bumps by using a magnetic seal to ensure no water leaks, even if you're off-roading. Run Time: Four to six hours | Power Source: Corded USB | Weight: 3.74 ounces Best for Water Bottles: Pure Enrichment Ultrasonic Cool Mist Humidifier Courtesy of Amazon Buy on Amazon Buy on Walmart What We Like It can fit in a carry-on Quick set up A standard water bottle instantly converts into a humidifier What We Don't Like Only functions on AC cord Uses disposable plastic bottles Light can't be turned off You can toss this humidifier in your purse or carry-on, thanks to its tankless design—the 5.5 x 2.5 x 5.5-inch product uses a standard water bottle for the water source instead. A single 16.9-ounce water bottle lasts up to six hours and covers up to 160 square feet of space. While you won't find a ton of bells and whistles (it has a soft blue light that can't be turned off), this humidifier sets up quickly and features universal voltage for international use. One frequent traveler who left a review said they "could feel the difference upon waking with one usage." Run Time: Six hours | Power Source: AC | Weight: 12 ounces Best Portable: Figrol Mini Humidifier Courtesy of Amazon Buy on Amazon Buy on Walmart It's amazing how something this small can transform a space. The slim, wand-like design uses any water receptacle to create an instant ultrasonic humidifier. In addition, you can easily adjust the length to work with different containers—a hotel glass of water or water bottle in the car quickly transforms any atmosphere. And what makes it stand out from the other small humidifiers is that it's one of the few that's genuinely wireless; it features a rechargeable battery, so the misting device can be untethered on a plane, train, or car. But be prepared for a maximum of a few hours in battery mode. The good news? Simply plug it into a USB port and extend that time. Run Time: Up to five hours | Power Source: 800mA battery | Weight: 5.6 ounces Best for Nightstand: SmartDevil Mini USB Humidifier Courtesy of Walmart Buy on Amazon Buy on Walmart What We Like Large 50-milliliter capacity It lasts up to 18 hours Soothing, warm night-light option What We Don't Like Leakage complaints While trying to get some quality shuteye on the road, that last thing you want is to be woken up by dry air because the small portable humidifier shuts off at 3 a.m. That won't happen with the SmartDevil; it has a large volume of 500 milliliters, so it can last up to 18 hours. Plus, it's super quiet (below 30dB) and has multiple light modes depending on your sleeping preference, including no light at all. As far as aesthetics, it comes in four simple colors—blue, gray, white, and pink—to fit seamlessly on any nightstand. And don't worry if you forget to turn it off: The humidifier turns off if the water level is too low, so all you have to do is rest easy at your home away from home. Run Time: 12 to 18 hours | Power Source: Corded USB | Weight: 8.3 ounces Best Lightweight: OURRY Mini Humidifier Courtesy of Amazon Buy on Amazon What We Like Adjustable length Compact What We Don't Like Filter only lasts a few months No interval setting It needs to be plugged in Run Time: Up to eight hours | Power Source: Corded USB | Weight: 2 ounces With a weight of just 2 ounces, this humidifier is about as light as they come. But it has a lot of capabilities for its size. It uses ultrasonic technology to operate quietly and has an adjustable length for use with a water container of your choosing; the tankless design allows it to be so small, but any cup of water or water bottle works with the product. While it takes up about as much room as a smartphone in your purse, it requires a USB port connection to function. As one reviewer described it, "I find this donut humidifier ideal for travel because it can be kept in a carry-on toiletry bag and be shortened to fit into a small cup/bottle." Final Verdict If it's portability you're looking for, the Figrol USB Portable Mini Humidifier (view at Amazon) is going to be your best bet, as it's the only one that's 100 percent wireless. But if you want to guarantee a whole night of cool mist bliss, opt for the SmartDevil Mini Humidifier (view at Amazon) with up to 18 hours of run time. A happy medium? The GENIANI Portable Cool Mist Humidifier (view at Amazon) can last overnight and easily fit into your car cup holder. What to Look for in Travel Humidifiers Run Time If you plan to use your humidifier for short periods while on the go, a smaller product with a shorter run time won't be a problem, especially since it can easily be refilled. But if you're hoping to enjoy a long overnight without misting interruption, a humidifier with a larger tank and run time is the better choice. Power Source Do you want to be totally wireless, or is a USB attachment okay? Those are questions to consider when deciding on a travel humidifier. While a wireless rechargeable battery product will allow you to bring cool mist wherever you go, run time can be limited. Meanwhile, a USB-connected product will provide longer use, but you'll be more tethered as it requires access to a computer, outlet, car charger, or power bank. Water Source There are pretty much just two options when it comes to travel humidifiers: tankless or not tankless. Tankless products tend to be smaller and lightweight, but you will need to find the water source. That could be a plastic water or another receptacle like a mug, depending on the humidifier. Ones that come with their own tanks tend to last longer and require no extra sourcing legwork, but they could be a bit bulkier. It's your priorities that matter. Why Trust TripSavvy?
