As in the previous case, the more, the better. However, it is easy to know its practical application or in other words, in which cases it is recommended.
• mode. In addition to different speeds, it can be interesting to choose models with air, night or eco functions. The first simulates the feeling of airflow, the second reduces noise and echo is designed to use less power.

• Additional: In general these devices can also act as fans (forget about water) and humidifiers, but there are also They purify the air including filters and/or ionizers.
• Design: If they have a big tank and are strong, chances are they will also be heavy and this is something that is not always attractive.
