## Questions & Answers

**Q: Why isn't my new wick working in my humidifier? They are the correct size and I soaked it but still no vapor being made**
A: I had the same problem with one of mine. I have 3. My husband kind of leaned the top to one side and then it started working. If not, contact the company and maybe they can help you.

**Q: Do they fit in wallflower plug-ins?**
A: I think just depend on the side, if too long they can cut.

**Q: Will they fit the O-Mei small humidifier?**
A: I am thinking that it will. They were too short for my humidifier. I had to use two of them and cut one of them to fit.

**Q: Do these work in uodbuyo usb air humidifier?**
A: Yes, they do.
