## Questions & Answers

**Q: Add essential oils directly to the aromatherapy pad? Do I need to do anything else?**
A: Dear Customer,
Thank you for your question.
You can add essential oils directly to the aromatherapy pads.
However, when adding essential oils, there are several issues that you should be aware of.
1. Don't put the essential oil drops on the spout, this will cause the spout to be blocked and thus no mist will be sprayed.
2. Do not put essential oil drops in the water tank, this will lead to affect the amount of water sprayed or damage the humidifier accessories.
We have made a special video for you to watch.
We hope you can enjoy our products better.

Regarding the cleaning of the humidifier, we offer the following suggestions:
1. You can use a cotton swab dipped in a little vinegar or alcohol to wipe the spray port, the use of vinegar or alcohol can effectively remove the dirt.

**Q: Are there replacement filters? What should I pay attention to when replacing the cotton swab?**
A: Dear Customer,
Thank you for your question.
The extra swabs have been placed inside the package and there are 2 swabs in the package.
When replacing the swabs, there are several issues that need your attention.
1. the swabs need to be fully soaked for 3-5 minutes before use to ensure that the swabs can squeeze out the water from both ends.
2. When replacing, be careful not to lose the spring at the bottom of the swab tube and make sure the larger end of the spring is at the bottom of the swab tube.
We have made a video especially for you, the specific operation of replacing the swab you can watch the video above.

**Q: How long does this humidifier last when filled with water?**
A: I have not accurately calculated its working time. But I added water before going to bed at night. When I woke up, the humidifier was still operating. I think it is very convenient to avoid the trouble of adding water in the middle of the night. I love this product.
