## 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.

    They’re too short
  

*by H***H on Reviewed in the United Arab Emirates on 25 May 2022*

Unfortunately, these are 3in and I need the 6in ones. I couldn’t find where they mentioned the size so now I have to order the correct ones.Not sure if they’ll take these back being that I’ve used 2 pieces to fit the 6in size I need.

### ⭐⭐⭐⭐⭐ 







  
  
    Works fine.
  

*by R***. on Reviewed in the United States on 20 January 2024*

This item (5.9 inch filter) fits perfectly in the Treva portable humidifier (model AEHB002).I soaked the filter in cold water for 5 minutes, before installing.  It's working fine, without any issues.
