## Customer Reviews

### ⭐⭐⭐⭐⭐ Stylish and Effective
*by C***Z on October 16, 2023*

This is a beautiful humidifier/nightlight! I live in Southern California where the air is extremely dry in the fall and winter, and using this humidifier while I sleep helps me breathe so much easier and not wake up with dry eyes and a dry throat. It's also amazing if you have a head cold and are having trouble breathing from blocked sinuses.The best feature in my opinion, other than looking nice in my bedroom, is the fact that it is a closed-top humidifier and the tank is sealed, which helps keep the water inside clean and free of contaminants like dust or lint. It is very easy to use -- just unscrew the lid on the bottom of the tank, fill with water, screw the lid back on, and place the tank back on the base of the stand. On the low setting, the humidifier uses about half of the tank of water over the course of the night. When I wake up, my sheets and carpet aren't damp. The nightlight feature is great if you want it on, and easy to turn off if you don't.One thing I will note is that the humidifier does make a slight gurgling/bubbling sound on the low setting, and a slightly stronger bubbling sound on the high setting. This didn't bother me personally, but if noise is a big consideration for you, I would be advised that this unit is relatively quiet, but not whisper-quiet.Overall, this is a great humidifier that works as intended.

### ⭐⭐⭐⭐ Works well but expensive.
*by T***. on October 14, 2023*

This is the first humidifier I've bought in about 20 years so I'm not a connoisseur or expert in humidifiers. I liked the look of this and that it had a tray to put in essential oils for aromatherapy. I didn't shop around because I was in a hurry when I got this, but after getting it, and looking more into it for this review, I see there are plenty of other 4L humidifiers that are much less expensive. I didn't read the specs on the less expensive ones nor do I know what makes a humidifier better than others, so it's quite possible the less expensive ones are poorer quality or design, etc. What I can say about this one is that it works well and does the job for which I got it for so I'm not too jaded about spending more for this. I really like the rounded design of it and while it has a low profile and could be put in tight spots on the floor, so far I've been keeping it on the table because the light and watching it operating and bubbling is very relaxing. As the directions suggested, I put in a couple drops of essential oil in the diffuser tray, but I don't really smell it. I can smell a hint of it if I put my nose in the mist, but it's not carrying out to the room. I will probably put more oil in the next time. I also really like how simple it is to operate. It just has two settings: hi and low. And I like that it's the old-fashioned dial instead of digital buttons or a remote. And there is a button to turn the light off and on. For me I rationalize it was worth it to spend the extra money because I like the design, but other than that, I'm not sure why it's more expensive than comparable products.

### ⭐⭐⭐ Smaller than expected, not.a top fill
*by A***S on October 12, 2023*

I honestly expected more from this. It feels cheaply made, I don't think it will last long. The tank is kind of weird, I've never used one like that before. It seems like it will work ok, not sure how long it will last though. The tank is much smaller than what I envisioned 4L being, it's smaller than my current baby humidifier. It does work though, and once I figured out the tank is fairly easy to use.
