Worth the money!
I have purchased COUNTLESS different humidifies over the years. In the end I never really liked the ones I purchased and would only end up using them for a short amount of time. This one is very well made, the parts are sturdy not like some of the cheap plastic ones I had purchased previously. It is very user friendly, you can fill it up and turn it on and get it going right away. I feel the tank capacity is good sized for your average sized bedroom. I love that it has a display for the humidity instead of having to try and guess what the humidity of the room may be at. It is also quiet which is a huge plus for me as I don't like hearing the loud noise in my bedroom. It has a light function which I don't use as I prefer it dark in the room, but some people may enjoy that feature. I also found it easy to take apart and clean which is always a plus. I have noticed a huge improvement in the humidity level of the room since having purchased this. It is an absolute MUST in the dry cold winter to have something like this it has helped my sinuses a great deal.

Perfect humidifier
Perfect humidifier for a regular sized room; works great in the bedroom, struggled a bit to keep up with my living room with tall ceilings. Using it in the bedroom, the water tank lasts 2-3 days without needing to be refilled (this is also during winter when the air is dry). The one in my living room needs to be refilled every day. The panel light is a bit bright for sleeping but using the night mode is wonderful. Cleaning the tank is an absolute breeze. Also, since it’s top loading, it’s very convenient to refill it using a pitcher rather than having to carry the whole tank back and forth like with other models.

Humidifier and App easy to set up. Nice unit.
It is very nice. Has been working excellent for the couple days I’ve had it. Humidity stays very close to where it is set and the app on the phone is handy and easy to operate. It’s a nice size, sturdy, was easy to set up. I like the settings for the mist and the nozzle to direct it. Very happy with this humidifier. Glad I went with a sturdier one with the app and top fill.

Overall a good humidifier
Love the humidifier it stopped my boyfriends nose bleeds but it takes 2 gallons of water every day to fill and it runs out every day. Its very quiet and I have a bedroom that used to be a 1 car garage and it works good for the size. I recommend getting those humidifier fish things as well so youre humidifier doesnt get water lines on the inside. Theres not a nasty smell or anything to the humidifier and it doesnt get hot either so It works great for us. It's just refilling it daily thats a bit frustrating but when its trying to bring humidity to a room this large I can understand.

Good capacity, easy to use, set a schedule from the app, this is my second purchase and I love it
I purchased this LEVOIT Humidifiers for Bedroom Large Room Home because I already had one from last winter and absolutely LOVE it. It is so quiet and it has so many great features, especially operating it from the app and setting up a schedule to turn on and off. I set mine to turn on every night at 10:00 p.m. and turn off at 6:00 a.m. It is very quiet and it provides a cool mist. This has helped me so much this winter with keeping my sinuses from drying out due to having the heat on. I use BestAir 3BT-PDQ-6 Original BT Humidifier Bacteriostatic Water Treatment in my units to keep the units clean and from getting funky. I put three capfuls in the water tank each time I fill the tank with water. This has also helped my older humidifier unit and it's staying clean and not getting any type of funk or buildup. I have to fill with water about every 2-3 days. I have had zero trouble with my older unit which is why I chose to purchase another just like it. It's a good, manageable size and really easy to use.

Works like a Charm ~ Super Quiet
This humidifier has been working out very nicely during these dry winter days to reduce dry skin. I like being able to turn it on & off with the phone app, Wi-Fi smart, I love it! I can adjust the mist output, switch modes, and even set schedules all from my phone with I'm still at work or lying in bed without having to get up. I use bottled water as it states for best results & longevity of this unit. One more notable feature is that it is super quiet. Easy to fill. I highly recommend.

A nice, quiet humidifier
I like that it has an app you can control it with. And I really like that it fills from the top. It is very quiet and very easy to operate. I also like that it can run with no lights at all which is great overnight. I’ve only had for a week but so far I’m very impressed!

Great Quality Humidifier
This works great! Very easy to set up and use. You only need to lightly wash the water tank before the first use. The 4 control buttons that operate the humidifier need only a light touch to activate (Power, Mist Control-High/Medium/Low, Light, and Sleep Mode buttons). Great quality. Lightweight. Very nice mist output. Definitely recommend it if you’re looking for a medium size humidifier.

Muy buena capacidad en litros, por lo que puede durar hasta varios días (en automático). La app para controlarlo desde el cel es LO MEJOR.

J'ai acheté ce produit notamment pour fournir un meilleur taux d'humidité à mes plantes d'intérieur. Pour le moment, rien à redire, il fonctionne parfaitement. La fonction 'Auto' lui permet de se déclencher dès que le niveau d'humidité passe sous un certain seuil et de s'arrêter de la même manière lorsque celui-ci atteint le niveau fixé. Il est aussi possible d'utiliser l'appareil en mode 'Manuel' en le déclenchant soit même et choisissant un niveau de brumisation. Le remplissage se fait très simplement par le haut et le contrôle via l'application VeSync est un petit plus pratique.

Works great for our living room (8x5m) I also got it to work in home assistant. I bought this model specifically for using it in home assistant and because of the good reviews. +: Big tank, silent, clear display, the cats stay away from it, app works great - : You have to create an account (I read somewhere that a credit card is needed. This is not true!). If the company takes down the service, the home assistant integration stops working. All together a great machine!
