The SPT Portable Humidifier is a travel-sized ultrasonic unit that screws onto an ordinary water bottle instead of using its own tank. It puts out about 120 cc of cool mist per hour, with adjustable output and a refill indicator, and runs on a 100–240V adapter for use abroad. It suits travelers, desk workers and nursery use where a full-size humidifier is overkill. Against tank-based personal humidifiers it is lighter and needs no reservoir, but the bottle is the tank, so output and runtime depend on what you supply.

Lowest price we've seen: $17.08 on Nov 4 at Opentip.com. Tracked across 11 stores since Nov 4.
Ratings are middling at 3.5 out of 5 from 11 ratings, so reception is mixed. Buyers value the bottle-based design and portability; the limited output and dependence on a bottle are the usual sticking points.
The SPT Portable Humidifier is a compact, lightweight personal humidifier. It is small enough to fit in luggage or a carry-on. It uses ultrasonic technology to produce a cool mist and runs quietly.
It has no water tank. Instead, it runs from a water bottle, and the two included bottle adapters fit different bottle sizes. The 100-240V AC adapter allows use with different power supplies. The mist is adjustable, and a water refill indicator shows when it needs water.
It can be used when traveling, at work, or in a nursery.
