Our Top Picks

Best Overall: Fancii Cool Mist Personal Mini Humidifier

Fancii Cool Mist Personal Mini Humidifier

Fancii’s Cool Mist Personalized Mini Humidifier checks all the boxes. It’s relatively inexpensive, weighs only 3.68 ounces, and is easy to use. Yet despite its miniature size (about the dimensions of a hockey puck), it’s a powerhouse of a humidifier, utilizing ultrasonic tech to project hygienic, humidified air with a noise measurement of a modest 15 decibels.

You simply screw the device onto a filled standard-sized water bottle (like a 16- or 20-ounce Dasani, Aquafina, Smartwater, Fiji, Evian, or Soda bottles—just as long as they don’t have low-profile necks), flip it over, place on the nightstand, and turn it on. You can let it run till you hit the max time of eight hours (when the unit automatically shuts off) or set it to turn off at two, four, or six hours.

It runs on three AA batteries—meaning cable-free ease—that last for up to 18 hours. Or plug into a power source via the included USB cable. And, should it matter, the Fancii also wins style points, with a simple-to-use interface anchored around a gold metal ring that nicely complements the white upper and lower sections of the device.

The kit comes with three filters, each of which lasts from one to two months depending on the frequency of use.

Best Buy: Sbogie Ultrasonic Cool Mist Humidifier

Sbogie Ultrasonic Cool Mist Humidifier

Amazon

With a retail price that doesn’t even break into double digits, the Ultrasonic Cool Mist Humidifier from Sbogie delivers a lot of comfort for less that one Alexander Hamilton. It comes with a 250-milliliter water tank nestled within its BPA-free silicone body, with an effective coverage range for a mid-sized hotel room for up to five to seven hours of blissful hydration.

The set-up is a breeze: take off the cap, pour in the water, bilge the cap, plug in the USB power cable, and turn it on. When the water runs out, it automatically shuts off. It also doubles as a mood/night light; simply press the power button longer to trigger light mode.

Since it has integrated water storage, it will take up more space than some of the more compact humidifiers on this list, but at just less than six inches tall and a diameter of 2.5 inches, it’s nowhere near cumbersome, and comes with two water filters that have the typical lifespan of one to two months.

Best for Using Water Bottles: CLBO Ultrasonic Mini Cool Mist Humidifier

CLBO Ultrasonic Mini Cool Mist Humidifier

Amazon 

The CLBO Ultrasonic Mini Cool Mist Humidifier has a more industrial look than our best-in-class selection, but it offers the same overall convenience of using water bottles to help you cut down on dedicated pack space while traveling. The device is compatible with standard-neck 16- and 20-ounce water bottles, and a mist control knob lets you adjust the volume of the cloud and humidity level to fit your needs.

It doesn’t come with programmable time intervals, but it will shut off when the water runs empty. And though it’s a touch louder than the Fancii humidifier, the 25-decibel level is still on the quiet side (less than the sound of thumbing through a book). Unlike other models, this device also works with essential oils; just add a few drops to the water to add fragrance to the experience. One caveat: the device always emits light, a mellow blue shade when it’s operating, and red when it stops, which might add too much ambient light for lighter sleepers.

Best for Small Spaces: Dogoo Mini-Portable Creative Humidifier

DOGOO Mini Portable Creative Humidifier

Amazon

With a max water volume of about eight ounces, the Dogoo Mini-Portable Creative Humidifier has one of the lower water capacities for a travel humidifier, optimal for smaller hotel rooms or for when you want the device to sit on the nightstand by the bed. The humidifier is tear-shaped, with a long neck that extends into the included water bottle—or, if you want to pack light, into a glass or other bottle of water. Go with the latter and the water volume is dictated only by the size of your portable water bottle (an approach that wins bonus points from an eco perspective, since you don’t have to use a plastic bottle). With a noise level of fewer than 15 decibels, it’s one of the quieter humidifiers on this round-up and runs for up to 12 hours with an auto-shutoff feature.

Power comes from a standard micro USB port, meaning you’ll always have to be plugged in to operate the device.

Best for Light Packers: Figrol Portable Mini Humidifier

FIGROL USB Portable Mini Humidifier

Amazon

Shaped like a small donut perched on a wide straw, the Figrol Portable Mini Humidifier weighs a feathery 2.4 ounces and comes with two height options for the stem, so you can drop it into a hotel glass or your own travel water bottle. Just soak the cotton core a few minutes before slipping it into the humidifier tube. Then plug the USB cable into the head of the device and turn it on; it’ll automatically shut off when it registers that the humidity rate drops, meaning the water level has receded. As with other small devices, it’s best when used in smaller spaces—think tinier hotel rooms or your car—or when you’ve positioned the device close to the target area.

Best for 24/7 Coverage: Boneco Cool Mist Utrasonic Humidifier

BONECO Travel Cool Mist Ultrasonic Humidifier

Amazon

In many ways the Boneco Cool Mist Utrasonic Humidifier shares many of the same characteristics and configurations as other plastic water bottle-compatible humidifiers, but this one rises above its competition thanks to the ability to humidify up to a full gallon of water in a 24-hour period and is compatible with most PET bottles; Boneco recommends a 17-ounce bottle, but if you can balance larger bottles on the device (perhaps bracing them against the wall), it offers some serious output, enough (as several users have noted) to fill a good-sized hotel room.

The device converts the water into a fine mist blown into the room via a small fan, with a variable output controller to help set the perfect degree of humidity, and automatically stops running when the water is depleted. As with the CLBO humidifier, this model also always emits light when it’s on—blue when it’s running, red when it’s empty.

Best for Colorful Simplicity: JZK Mini Portable Personal Humidifier

JZK Mini Portable Personal Cool Mist Air Humidifier

Amazon 

Spherical in shape and with eight of color options, the JZK Mini Portable Personal Humidifier lets you add your choice of mood lighting the humidifying relief you desire—and a lifetime guarantee offers confidence that the easy-to-use device didn’t lean into simplicity at the cost of reliability. Roughly the size of a grapefruit, it uses a high-density cotton filter to purify the six ounces of water that you pour into the device mist. Just fill it up, attach the lid, plug in the USB cable, and turn it on; it glows a light shade of blue (or green or pink or…) and runs for about eight hours. The BPA-free device runs whisper-quiet, but its diminutive size means it’s not ready for a marathon of double-digit-hour humidifying. In fact, it automatically shuts off after three.
