    Great humidifier
    Excellent little humidifer. I don’t use the app, so maybe that’s not very good, but i don’t have to use the app as it works great by itself. The tub on top is easy to remove, carry, fill, and reinsert without spilling a drop of water. The buttons are all easy and useful and the humidity indicator is very intuitive.The ONLY problem i could possibly have with this product is that the ‘auto’ feature, if you turn the humidifier off with it enabled, will spew mist for about a minute when turning it back on, even if humidity is higher than the max. The indicator said 80% and it still spewed mist after turning it on.It’s also virtually silent, if it makes any noise it blends into the background and is perfect white noise to sleep.I am almost angry this company doesn’t make dehumidifiers cause i’m sure they would be just as good.

    Great Quality!!
    Levoit Humidifier ReviewI absolutely love my Levoit humidifier! From the moment I set it up, I found it incredibly easy to use, and the app integration is a game changer. Being able to control the humidifier directly from my phone adds a level of convenience that I didn’t know I needed.The app provides real-time information on the humidity levels in my home, allowing me to make adjustments on the fly. This feature has been particularly helpful in maintaining a comfortable environment, especially during dry seasons.Overall, the Levoit humidifier has exceeded my expectations with its ease of use, smart technology, and effective performance. I highly recommend it to anyone looking to improve their indoor air quality!

    Great Humifidier
    I’ve had several water diffusers for essential oils which are like mini-humidifiers, but when I got this terrible cold that was murder on my sinuses & throat I felt the need to upgrade.Since I was sick when I first received it was awesome that it came with a quick-start guide because I barely wanted to open the package and deal with a new appliance.It was super easy to set up and the app even seamlessly prompts you to connect your existing smart assistants (Alexa, Google Home, etc).I love the option to combine warm and cool mist for maximum benefit. Within the hour my sinuses and throat were already feeling improved.The top-fill is really convenient but you can also remove the water tank to bring to your sink to fill, so I like that versatility.It is also very quiet. When I went to record the video I wanted to demonstrate the noise level but quickly realized I had a lot of background noise to turn off (A/C, a fan & a robot vacuum)…as soon as those were off it was nearly silent. All you could hear was a soft bubbling noise which frankly is soothing anyway.Longevity is important when it comes to appliances like these, so I will update as time goes on, but so far so good and I am very pleased.Pros:- Quick & easy setup- Versatile settings- Convenient refill options- Integration with virtual assistants- Powerful- Aromatherapy pad works wellCons:- A little pricey- Wish it had dual-aromatherapy pads like some other modelsOverall I would recommend 5/5.Will update it there are any issues regarding cleaning, maintenance, or longevity.

    Effective, but uses a lot of water.
    This humidifier seems to work well with the dry winter air. i have to refill it at least once a day, which isn’t too big a deal, but i stopped using distilled water due to cost. Using tap water leaves a white dust on everything in sight. Not specific to this machine, but a pain. Otherwise, nice and quiet. Includes app, which tells humidity, but would have been better to show water level and maybe alert to an out of water situation. As it is, app isn’t too useful.

    Efficient
    This has to be the best humidifier made. It works well, has a large reservoir, has a night mode, is quiet, fairly easy to clean and has replacement parts. We bought one for each room!

    Effective humidifier and good connectivity
    I love that i can control from my phone and program times. And it actually does a great job controlling the humidity. Some humidifiers don’t have great sensors to turn off by themselves and make the room too humid. And this can keep up in winter and even do a cool mist in the summer.

    The Best Humidifier I’ve Ever Owned – Worth Every Penny! A Game-Changer for Comfort and Health
    I recently bought the Levoit OasisMist 450S Smart Humidifier, and it has honestly changed our lives—especially for my daughter. She used to get sick often during the winter with constant coughing and congestion at night. Since using this humidifier, she’s not feeling nearly as sick anymore, and her nighttime congestion has improved dramatically. It even helps reduce her cough and cold symptoms within just one night. I was blown away by how fast it worked.What I Love:• Warm & Cool Mist: We mostly use the warm mist at night, and it’s been amazing for clearing up stuffy noses. The cool mist is great during the day or in warmer weather.• Smart Controls: I use the VeSync app to control everything from my phone. I can check humidity levels, set timers, or just adjust the mist level without getting up.• Auto Mode: This is one of my favorite features—it senses the room’s humidity and adjusts automatically, so I don’t have to think about it.• Large Tank & Top Fill: The 4.5L tank lasts through the night and then some. Top-filling is super convenient, and it’s easy to clean.• Quiet Operation: It runs silently, so it doesn’t disturb my daughter’s sleep at all.• Aromatherapy Option: I add a couple of drops of lavender oil at bedtime, and it helps create a calm, spa-like vibe in her room. We use the aroma box regularly, and when my daughter is sick, I put Vicks drops on aroma pad and place it near the nozzle. It works like a charm to open up her airways and ease her breathing overnight.Final Thoughts:If your kids struggle with winter colds, coughs, or nighttime stuffiness, I highly recommend this humidifier. It made a noticeable difference after just one night, and it’s now part of our daily routine. Levoit really nailed it with the OasisMist 450S—worth every penny!

    Excelente ayuda para dos problemas de salud agravados por la calefacción y el frío seco: ojo seco, fosas nasales y piel resecas. Muy notoria mejoría desde la primera noche.Además: ofrece vapor tibio (con tres niveles de temperatura) o frío, en ambos casos, con 3 niveles de intensidad o cantidad de vapor; tanque de agua grande que me dura hasta para 3 noches (no lo uso durante el día); detector que apaga el aparato automáticamente al quedarse sin agua, lo que evita descomposturas o accidentes; encendido y apagado automático y programable desde un aplicación fácil de descargar y usar, después de conectar el aparato a un teléfono o tableta mediante Wifi e identificar el humidificador (operaciones fáciles aunque NO soy un joven experto en computadoras y celulares) y un manual muy claro y completo, incluidas instrucciones muy importantes para limpiarlo y evitar descomposturas o que se formen hongos.Ruido muy moderado y luz del panel de control muy discreta que no me han causado problema alguno para dormir. La luz del panel puede apagarse, manualmente o al ponerlo en la función “Sleep” o Dormir.Varias de las críticas en otras reseñas se deben a no leer o no seguir sistemáticamente las instrucciones del manual, incluido el tipo de agua a usar, etc.Feliz con este humidificador que escogí después de leer muchas reseñas sobre distintas marcas y modelos. Para mí, vale lo que cuesta.

    Great product and easy to clean (which was my biggest concern). We love that we can set it on auto and it will just keep my son’s room at a consistent 50% humidity. Since using, my son hasn’t gotten 1 nighttime bloody nose
