Review: Great humidifier. Highly recommended. - I originally bought this for my OH who had a cough that kept him awake so badly during the night he was sleeping in the spare room at the time. It helped him a lot during the night. It is so silent I can't hear anything at all, and I like complete quiet and darkness in order to go to sleep. The mist is really fine and doesn't cause any moistness anywhere near where it sits. The light can be switched off, in fact I've never had the light on, and it can be on constant jet or intermittent which means one jet then another jet. It also feels very well made. Everything fits together perfectly. Worth the money and I recommend it. I'm not the kind of reviewer who gives 5 stars for everything but I can't fault this item. In fact I love it so much I bought another one so I can have one in another room. :)
Review: Dangerous product – avoid at all costs! - Dangerous product – avoid at all costs! I bought this humidifier in early June and it has already failed catastrophically. After only a few months of light use, the charging port overheated, burned through the casing, and left scorch marks (see attached photo). This isn’t just poor quality – it’s a serious fire hazard. A humidifier should bring peace of mind, not risk burning down your kitchen. The fact that this happened so quickly shows how badly designed and cheaply made it is. I would strongly advise against buying this product. Spend your money on something that is safe and built to last.

## 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.

Have a nice day!
Sincerely.

**Q: How do I clean this small humidifier?**
A: Dear Customer,
Thank you for your question.
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.
2. You can directly rinse the water tank with water.
3. Other parts you can directly wipe with a wet rag, but please pay attention to keep the charging port dry.
For safety, please unplug the power in advance when cleaning.

**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.
If you have any further questions, please feel free to contact us. Our after-sales email: consult@smart-devil.com

Sincerely.

**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.
