The 10 Best Portable Humidifiers for On-the-Go Moisture When You Need It Most
Growing up, a humidifier was a clunky machine your mom pulled out when you had a stuffy nose or sore throat. It lived under the sink or boxed away in the linen closet, an over-complicated tangle of filters and buttons and wires our parents would break out on feverish nights. The idea of lugging the machine anywhere further than the closest bedroom or even having a portable humidifier? Totally farfetched.
Thankfully, humidifiers have since gotten a makeover, and are now so streamlined and simple to use that you can (and should) keep them out regularly to breathe a little moisture back into your space. Yes, there are even portable humidifiers that provide some extra moisture wherever you need it—your car, the office, a hotel room—without relying on an outlet. Just charge 'em up before you go out, and breathe easier wherever you roam. Our childhood humidifiers could never...

What types of portable humidifiers are there?
Portable or not, it helps to know the different types of humidifiers out there. According to the United States Environmental Protection Agency (EPA), there are four types of humidifiers: evaporative, impeller, ultrasonic, and steam vaporizer. Evaporative humidifiers speed up the evaporation process of the water in the tank via a belt, wick, or filter. Impeller humidifiers, aka “cool mist,” use a high-speed rotating disc. Ultrasonic humidifiers use ultrasonic sound vibrations to create mist, and steam vaporizer humidifiers heat the water in the tank and then cool the water just before it exists through the nozzle.
What are the benefits of using a portable humidifier?
Dealing with congestion, battling allergies, or feeling a little under the weather? A humidifier helps keep you physically feeling your best. “If you suffer from congestion or sinus problems, humidifiers can help to thin mucus and make it easier to breathe,” says Dr. Sony Sherpa, MD, a holistic physician at Nature's Rise. “The added moisture in the air also helps to lubricate your nasal passages and reduce irritation.”
Humidifiers also keep your hair, nails, skin and lips moisturized. Low-humidity environments contribute to skin dryness and roughness—in as little as 30 minutes1 in low relative humidity, your skin will start to decrease in moisture and elasticity. Portable humidifiers combat dry air wherever you are by providing targeted humidity for your personal space. Even on the go, or somewhere like a hotel where you can’t really control the environment, you can prevent these negative skin impacts, sleep better, and feel better, all with one little portable device.

Canopy is renowned for its beautiful bedside humidifier, and now the brand has developed an easy-to-clean, high-quality portable humidifier that looks just as good.
