## Questions & Answers

**Q: How noisy is the humidifier when it is working? I am a light sleeper and need to be in a very quiet environment to fall asleep.**
A: No worries at all. I am also a light sleeper, and this humidifier has never disturbed my sleep. It is much quieter than I expected, especially in sleep mode. In fact, I sleep much better with it on at night since it does a good job in relieving my itchy skin which caused by dryness.

**Q: Can you change the direction of mist output?**
A: Hi,
Yes you can.  There is a straight wide piece that goes across 75% of its total length on the top of the humidifier that  can be moved around in order to change the directional output.  Hope this helps.  Shalom… :O)
