Consumer Reports

The SPT SU-1053 portable humidifier is designed to use in a very small room or—because a water bottle serves as the water tank—for travel. It excels at adding moisture to the air, earning an Excellent rating for output as well as for noise and energy efficiency. It sports an empty-tank indicator and automatic shutoff when the water is used up. If you’re refilling a water bottle with hard water, however, performance will suffer.

CR’s take. The stylish Stadler Form Emma E031 cool-mist ultrasonic humidifier, designed for areas up to 25 square feet, is the most expensive travel/personal unit in our ratings. It’s also a stellar performer in several of our evaluations, including convenience. In part that’s because the wide-mouthed water tank that comes with this humidifier is easy to reach into for cleaning. The Emma’s machinery can be disassembled to fit into the water tank, which in turn fits into a fabric travel pouch. To power up, use a wall plug, a USB cable attached to a computer, or a battery pack (not included).
