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.

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.

Quality humidify
I've read all the negative reviews and honestly they were more of a nitpicking rant then on the overall product. The one that resonated was about it leaking...hmmm. after all my research this one always rose to the top for its price range and quality. I've had it going on a month maybe more and it worked flawlessly. Infact it regulated the humidity in my room so well that it stayed at a desirable humidity percentage even with the machine off. Its not difficult to clean unless you lazy plus must parts excluding the base obviously can go in your dishwasher. So bottom line great price and great value.

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.

Big Tank, Quiet, Easy to Use. Smart Features Make It a Winner
This humidifier works really well and has been a great addition to our space. The tank is large, so refills are infrequent, and it runs very quietly, making it ideal for bedrooms or offices. It’s also easy to use and easy to fill, which I really appreciate for day-to-day use. Cleaning is a bit of a chore compared to how simple everything else is, so that’s really the only downside. On its own, that might make this a 4-star product. However, the price is right, and the built-in screen and companion app are a really nice touch, they make it easy to check settings and status at a glance. What truly pushes this to 5 stars for me is that I was able to connect it to Home Assistant and set up automations. Having it turn on and off automatically based on humidity levels has been fantastic and makes it feel like a much more premium device. Highly recommend if you want a quiet, capable humidifier with solid smart features and great value for the money.

Great product at an affordable price
This has been a great humidifier. I have had this for over a year now and I am pleased with how well it works and has held up over time. This unit has a really big tank for water storage which I really enjoy. I like that I don’t have to refill the water each time that I use it. So that is a bonus. It has adjustable settings, a night time mode where you can shut the control panel lights off while you sleep and it also has a neat nightlight option which is really handy. Overall very pleased with this humidifier compared to others I have purchased and used in the past.

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.

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!
