Excellent room humidifier
Reviewed in the United States on June 7, 2026This is the best humidifier I've ever had. It is dead quiet. Easy to use and holds lots of water. I get two nights plus without having to refill the tank. The amount of mist is easy to control and it shoots the mist higher than other humidifiers I've had. The top rotates so you can direct which way the mist should come out. There are no LED lights on it. I've only started using it, but I can tell from the space under the tank it would be easy to clean compared to other humidifiers. There's just not a lot down there to interfere with cleaning. The only peeve I have is the company name on the front of it. I don't like that. But otherwise the thing is excellent. I'm glad someone figured out how to make the perfect humidifier. I highly recommend.

Great humidifier

My only issue is that the top coating on the black ring has flaked off. Why is this happening? Should I be concerned?

The Humidifier That Passed the K.I.S.S. Test (Mostly)
Reviewed in the United States on March 12, 2026I've been in a complicated relationship with humidifiers. My last one had a temperature readout, a humidity display, and four buttons I had to locate by feel at 2 a.m. like a submarine navigator. It was a humidifier that wanted to be a spaceship.
This one has one knob.
One knob. Turn it, mist happens. Turn it the other way, less mist happens. I'm a technology guy and I love more features. But the older I get, the more I realize sometimes simpler is better. A humidifier doesn't need to be complicated, and LEVOIT got the memo.
THE TANK SITUATION
Levoit claims the 3-liter reservoir will get you three nights between refills. In my experience, it's closer to two. I can only assume I sleep more than the average person, or the marketing team sleeps less. Either way, two nights between fills is still perfectly fine, and I suspect if you run it on lower mist output you might stretch it further.
The fill experience itself is genuinely improved. The whole top comes off and the tank is small enough to fill right at the bathroom sink. My previous humidifier had a reservoir the size of a small aquarium — I had to carry a pitcher of water across the room like I was rationing supplies during a siege.
OPERATION
One knob controls mist output. A 360° nozzle lets you direct the mist wherever you want it. That's the whole control panel. No app. No schedule. No WiFi. The auto-shutoff when the tank runs dry is a thoughtful touch — you won't wake up to a machine groaning at 4 a.m.
NOISE
I didn't mention this earlier because there wasn't much to say: it's quiet. You notice it briefly when you turn it on, and then you stop noticing it. It's whisper quiet.
AESTHETICS
The design is clean and unobtrusive. It blends into the room rather than declaring itself. For something that runs all night on your nightstand, that's exactly what you want.
THE DIFFUSER FEATURE
The product listing mentions you can add essential oils to a base chamber and use this as a 2-in-1 diffuser and humidifier. I haven't tested this personally, so I can't speak to how well it works — but if aromatherapy is part of your sleep routine, it's worth exploring.
VALUE
Can't beat the value. I paid less than expected.
BREATHING IMPROVEMENT
My wife swears she sleeps better and breathes better when we run it.
BOTTOM LINE
If you want a humidifier that does its job without requiring a learning curve or a second glance at the manual, this one delivers. The tank claim is slightly optimistic, but two nights of uninterrupted sleep before a quick sink refill is a reasonable trade. Sometimes the best feature is the one you don't have to think about.

Top Filling
Reviewed in the United States on February 19, 2026This is great because it is filled from the top! Our old one required carrying it over to the sink to fill and bringing it back to the unit to reinstall. It was heavy and would leak as we carried it. It also humidifies the air very well. It’s quiet and lasts about 3 nights before needing to be refilled. It also does not have an annoying night light on it and turns off if it runs out of water. We’ve had many humidifiers over the years and this is our favorite!

Mold grows rapidly
Reviewed in the United States on April 2, 2026This humidifier is pretty user friendly, quiet and effective… BUT it accumulates mold/mildew rapidly. It’s also easy to refill it. The water that gets sucked into the bottom base part is always in there, even after the machine reads empty and kicks off. Pink mold/mildew grows down in there. Even when you leave the top off when it’s not in use it happens. Due to the design, there are a lot of little cracks and crevices to clean the pink mold off of/inside of. I wish I could return it but I am past my date. I don’t want to spread moldy air into my home.

S5 out of 5 starsWorks great!
Reviewed in Canada on August 22, 2022Been using this for little over a month now and I think it's great! My room is quite small so I don't fill it to the max, but about 1/3rd is typically enough for the night and it does shut off on its own which is convenient. Plus the only indicator it's sleep mode is a small red light which isn't bothersome at all.
I use this thing with distilled water and essential oils more or less every night and I clean it out with vinegar and water (as how instructed) only once a week instead of every 3 days but even then I've had no mold or weird smell problems. It's actually super easy to clean and it's really light despite its size which is a huge help for someone like me who has ADHD and weak noodle arms.
The only reason I put 4 stars for the noise level is because there IS a hum that can be audibly heard (disclaimer: my small room and I put this pretty close to my bed, so it might not even be audible in a big room) so it's not totally silent. Ironically, for me personally this is better because it now doubles as a white noise machine which is awesome lol. All in all this has saved my room and my skin from being dry as hell all while looking pretty sleek so I'd recommend it!

Giselle Molano4 out of 5 starsGreat humidifier overall
Reviewed in Canada on January 6, 2026The Levoit humidifier works really well and noticeably improves air moisture, especially during dry seasons. It’s quiet, efficient, and easy to use, making it perfect for bedrooms and nurseries. I love the sleek design and how well it maintains a comfortable humidity level.
The only downside is the cleaning part—it takes some effort to clean thoroughly, and it can easily get stained if not cleaned regularly. With proper maintenance it’s manageable, and the performance still makes it worth it.
