To get the most of a personal, portable humidifier, the user might have to frequently add water to the tank while in the case of the normal sized ones, a full tank can work for over 10 hours.

On the plus side, most of the portable humidifiers have the same functions as the standard ones: auto-shut off when running out of water for extra safety, multiple mist modes, night/ambient light. This is what makes them ideal for traveling, commute or work desk. If you want to fight the unpleasant effects of dry air, there is no need to compromise. You can rely on these little gadgets to improve the air’s quality wherever you are.
