   Es muy práctico porque puede encenderse/apagarse remotamente gracias a la aplicación para el celular.
   Tiene 4 diferentes niveles a de operación y solo no le pongo las 5 estrellas porque no sube mucho el vapor, se queda hasta unos 20 cm por encima del aparato.

   Works as it should. DO NOT use regular tap water in this style ultrasonic humidifier. It will aerosolize any particulate (calcium, bacteria, etc) in the water and breathing that is unhealthy for your lungs. This will be visible as a white powder/dust on surfaces near it. Use distilled or maybe reverse osmosis water only!

   UPDATE: so i’ve had this for like, 8 months. my one issue with it is … it smells. i use distilled water. i clean it after every use and allow it to dry (i set up a small desk fan pointing straight inside of it to dry it even better) – there’s no smell once i clean it, of course. then, i add a gallon of distilled water and set it up and within a few hours (i run it on the lowest setting, and i’m sure this is the issue. because this makes it go longer than 24 hours [though this smell happens wayyy before 24 hours]. i’d guess the water lasts about 40 hours on low), it stinks up the room it’s in. it smells like when clothes don’t dry all the way. that mildew smell. when i take it apart to clean it, there’s pink stuff (bacteria) in a lot of places, especially this one piece that comes off (only way to clean it properly – see pics). this would be so perfect if it just didn’t stink up the whole area it’s in. when you smell the water coming out, while the humidifier is running, it smells like mildew and it just makes ya feel like you’re spreading that all over the room. so, my advice is – don’t run this for longer than a few hours without cleaning it. i really wish it would last a whole gallon. i don’t know what to do to make this not happen. i follow the instructions for cleaning. again, there’s no smell after cleaning and when it’s first in use. i’d love to know how to make sure this doesn’t happen. i’m fine with having to clean it. that’s just what you have to do. it’s water in a closed container. but does it have to smell.. and so soon? 😩 still absolutely love the app. ORIGINAL: I am IN LOVE with this (had to say it again). I absolutely recommend it. I haven’t tried to clean it yet, but I looked at how the humidifier is put together and read the manual and it doesn’t seem all that hard – if that changes, I’ll edit this. But honestly, I was so nervous about this purchase. I looked at soooo many options and it was so overwhelming. I’m glad I settled on this one. The app is really cool. I don’t even touch the humidifier to control it at all. My son named it Wally. I have 2 hygrometers because I have a ton of houseplants and, while it’s not changing the humidity drastically (it’s not meant to. it’s meant to keep it comfortable. this isn’t gonna put your humidity at 80-90% or anything even close to that), it helps so much. Obviously I haven’t had it long enough to tell for my plants, but my boyfriends been really stuffed up and he’s been bragging about how helpful this has been. Within an hour of me having it on, he noticed a difference. We have a small 2 bedroom (752 sq ft) and I think it does well for the whole house, honestly. My hygrometer which was about 6 feet away, got to 54% with it on the second mist setting. I’ve only kept it on for a few hours at a time. I’ll set it for 4 hours here and there. I love that the app allows you to turn it off and on, set a timer for it, set how much mist you want. And you can direct the mist. It’s SUPER quiet. My space heaters are wayyy louder than this thing. 10/10 recommend. Absolutely.

   I gave it five stars because after adjusting to it, and not worrying about the little things and the false advertising of the “up to 40 hours”, I find this mister a great quiet device that will impact a 400 SF room and increase the humidity level. Let’s start with the cons: 1. In the manual that came with the mister, and on the levoitoutlet.com site it states, “up to 40 hours”. Well, it might as well say up to 100 years, because both will be true, but none real. I filled the water tank and placed it to work on the Low mist setting ONLY. The tank was empty after exactly 27 hours. Yes, it worked great, very quiet, and efficient for 27 nonstop hours! So, 40? Not in this world, no matter what you do to it. Of course, it will work even less on the Medium and the High settings, but I went with the Low only. 2. You can see in one of the images I added here that due to condensation at the top of the unit (mist nozle), there’s water that needs to be removed before you remove the top in order to lift the water tank, else you’ll have water all over your night-stand, bed, table, or wherever you placed the unit. This is not a flaw, but something I bring to your attention. Have a small towel of paper-towel next to the unit. 3. The Essential Oil tray, after pressed in, pops out a fraction of an inch and there’s no way to simply slide it out. I had to force the little tray after another reviewer commented that he experienced the same issue. After pinching the tray, it pops out completely (see the two images I attached) and you can place a few drops of essential oil. The good: 1. A gallon of water in the tank makes it running for a long time (up to 27 hours). 2. The unit is very quiet and doesn’t take a lot of room on the night-stand. 3. The mist setting levels (Low, Medium, High) have one toggle touch button and you can’t turn the unit OFF unless you went through all three levels even if you only use the Low mist level. The manual indicates that if you touch the On/Off button for three seconds it turns OFF the LIGHT in the button, but not the unit. This is actually a good thing because the blue light from the button can be turned off, especially if you intend to let the unit work through the night. 4. The unit has an Auto Shutoff sensor that will turn the unit OFF if there’s no water in the tank. 5. The manual is simple to follow, even if it is falsely said that the unit can work “up to 40 hours”. There’s an explanation on how to clean the tank, the unit, etc. 6. Just like you should expect, the mister will perform best with Distilled water – it says so in the manual, and I know so from the different types I used in the past. Do not use tap water. Do I recommend it? Yes. It does what it supposed to do.

   I bought this because it’s dry in my house and my nose was starting to have dry crusted blood in it and it was very uncomfortable. Within hours of setting it up, I felt relief. I have a 2 story home and have this downstairs. I would say downstairs is maybe 740 sqft open concept and it does a good job adding moisture to the air. I can’t say if there is more moisture in every sq fy of the downstairs but in the areas I spend the most time in it does. So far no leaks. I do have to fill it more than I like but that’s just part of it and it isn’t too difficult to do. I have not cleaned it yet so I can’t speak to the difficulty of that however if it proves to be very tedious or impossible I will come back and update. I’d recommend.

    I love this humidifier. My allergies are so bad and I needed a good humidifier. The humidity levels adjust to your needs and it works perfectly for my family and I. There is little to no noise. In fact, it sounds like a calming white noise. The capacity is perfect for my bedroom and you have the option to keep the lights on or off which was a huge plus. It also pairs with your phone so it easier to change settings and not have to get out of bed. Great customer service, great value for the money, very durable, and fast shipping. Thank you.

    Ya tengo con el producto varios meses, ha funcionado a la perfección. Humedece el ambiente y evita la resequedad en vías respiratorias superiores y previene algunas alergias debidas a las partículas que flotan en el aire, más si este es seco como en algunas temporadas o regiones geográficas.
