Air-O-Swiss U 200 Cool Mist


T he best humidifier that can provide you an optimum level of moisture without posing a risk for your children is the Air-O-Swiss U 200 Cool Mist. Keeping in mind that humidifiers with warm mist can release hot steam into the air, it is better to avoid them, especially if you have small kids around the house. A cool-mist model is safer than a warm mist unit because it can’t cause burns and other injuries, so people should pay attention to these details before deciding on a certain model.

This unit offers many interesting advantages, as it integrates a proper number of functions and properties that turn it into an effective device. Unlike other units that release a messy white powder into the room due to the minerals that exist in tap water, it integrates a technology that turns water into a micro-fine mist. The mist that it releases evaporates rapidly, so you won’t have to worry about the quality of your indoor air.

Some of these are:

  • It integrates a mist output regulator and a Hygrostat so that the machine can calculate and control the proper level of humidity
  • Due to the fact that it has a small capacity, it features a very quiet performance
  • It integrates an automatic shut-off function that allows the machine to stop performing when it runs out of water

However, it is suitable for rooms that measure up to 430 square footage, so it won’t be able to cover up very large spaces. Still, the fact that it is recommended for small and medium-sized rooms has many advantages. Due to the fact that it has a small capacity, it features a very quiet performance. Therefore, you can be confident that you won’t even notice it most of the time.

Another property is represented by the fact that it allows the user to monitor the water level through a transparent window in the tank. Furthermore, this option is very important because it can prevent the motor from overheating.


This product has been created with an adjustable rotating mist nozzle. This means that it will be able to release the mist in any direction you want. Even if you need it to spray in two different directions, it will do that. In addition to this, this product also has a fragrance container. Therefore, with a few drops of essential oil or fragrance, you will be able to scent the room. The greatest thing about this unit is the fact that it uses a little amount of energy. At only 20-watts, it means that you can have this model to function for the whole day and your energy bill will not be affected.
