LEVOIT Humidifiers for Bedroom, Smart Warm and Cool Mist, Symptom Relief

I'm really impressed with this LEVOIT humidifier! It works great for large rooms and the smart warm and cool mist feature is a nice touch. The quiet operation is fantastic — I barely notice it running at night, which makes it perfect for the bedroom. Setting it up was straightforward and the app connectivity works smoothly. The large water tank means I don't have to refill it constantly. Humidity levels in my home have noticeably improved and my sleep quality has gotten better. Highly recommend!

Wow - my sleep quality went from a 2 to a 10 in my house! I wasn’t sure why my sleep was so awful and it seems new heater devices in house just fried-dried up my house. I thought it was just typical wintertime but nope- this humidifier took my rooms from 29% to 57% and I couldn’t be happier in may 30?minutes tops! . The device shows you the humidity levels, gives you cool or warm mist and three levels too. Super easy to use and clean. The sound isn’t bad but the higher the mist level the more sound you hear so I put it in low overnight. To be able to breathe fully is priceless! The thing stays lit but I just face it backward at night. I’ve run this almost continuously 24/7 since I received it and I’ve had zero issues. One of the best buys I’ve made from Amazon.

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!

Okay, so this unit looks great, works super well, and is easy to clean! I purchased mine to help my skin in the winter/drier months. I like that it has an auto mode which maintains a humidity, different mist warmth settings, and is very quite. I DO have issues with it though. Features/functionality were purposefully left off of the actual unit in order to force buyers to use their app- yup they want access to your wifi, location, and all the other juicy privacy data they can sell; oh, and of course, when you open the app there's multiple notification marks to entice you into other menus which are advertising their other products. The unit has a sleep button- this will not work the way you think it would. It's not a setting for you to use at night when you sleep. It turns off any warmth setting, display, and runs *continually*. The first night I used it, I woke up to greenhouse of a room; when I turned the display back on, it read that the room was at 95% humidity. The sleep setting is just a low-noise, no-display mode, and needs constant tending to maintain a target humidity level- it does not auto shut off. Target humidity can be set, but you need to do it in the app. I see no reason the buttons on the device couldn't be multi-purpose. E.g. long-hold the auto button and enter a mode which allows you to adjust the target humidity with the other buttons. Same for the display, long-hold on/off or sleep to turn the display off. So how do you use this at night? Download the app... set your target humidity level, put the device in auto, adjust the warmth setting to your preference, and then scroll to the bottom of the app and find the toggle to turn off the display. Doing all this will let your device run at night with the display off and will turn itself off/on to maintain the target humidity. I honestly want to rate this lower because I just don't believe this needs an app (I'm very concerned about data privacy), and I know exactly why this was made the way it was...but it just works well. It's so quite, maintains humidity well, and is easy to maintain.

Great product, I have gone through a lot of humidifiers but this one is holding up so much better than those others, it's easy to clean and the water vessel in top pour which is so much better and easier. adjusting the humidity level with the app is so easy and I appreciate it that I don't have to be close to change it. Just need my phone! It is quiet and you can turn off the lights so they don't bother at night unlike other humidifiers.

Love this humidifier. It will humidify a 200 square room in no time, I own a Vicks humidifier and there is no comparison between the two. The app works flawlessly and is so convenient to control the humidifier before going to sleep. The only complaint I could have is that the sensor reading is inaccurate but that is not a concern to me, I keep a hygrometer in the room for measurement, given that it blows out humid air, I don’t think there is a way to make that accurate unless maybe the sensor placement could be improved. I adjust the schedule to run for 20 minutes each hour at night and this keeps the room comfortable in the driest season. Overall, this is a great humidifier to have. Cleaning it is not as bad as others say, I clean it weekly by putting the parts in water and vinegar and this keeps it perfectly clean.

It's wonderful. Looks nice. There are different programs. You can turn the display off and set it on a timer. Works great. Easy to fill.

Things good and accurate: 1) Easy to use 2) Quiet 3) Versatile - can do warm or cold mist 4) Display bright and tells you instantly what's set 5) Alternates between showing desired humidity and what the machine thinks it is 6) Easy enough bottom water fill tank 7) No leaks yet (knock on wood) 8) Remote works and is easy to use 9) Display can be turned off totally, only when out of water does the display show a small red water light (not that bright btw) 10) Auto-shutoff when out of water and it's really is as there is very little water left in the tank 11) Dual mist directors to allow two different streams 12) Decent controls of temp of warm steam, strength of mist flow, humidity level Things not so good: 1) It is a bottom fill tank which requires removing the tank constantly, longevity issue maybe? We were aware beforehand 2) Humidistat has lots of issues knowing what the humidity level really is in a room 3) The strength of the steam is controllable, however to be more effective it needed to be on high which meant the unit turned off before a 8 hour sleep timeframe was up, no idea how long it lasted, but it was off at 7 hours Things to be aware of: 1) When out of water and the display is off, you cannot do anything with the display and shouldn't because the unit is off, wait until you put the filled tank back on 2) When removing the tank keep it in the same position because tipping it releases what little water is still left (again, not much is left, just a little mess to clean up) 3) The lowest humidity % you can set is 40%, again aware of prior to buying The reason for the ding in rating is that despite this unit being highly rated the humidistat is WAAAAY too finicky when using warm mist. One second it's 39%, then 28% and the next it's 43% and the machine turns off. Then the humidity % drops enough to kick back on and we start over. This all is highly susceptible to air currents and even people coming near or walking by. Yes, the unit turns back on within a minute because the humidity level drops (to where it should be), but this can't be efficient operation in terms of energy and water usage. Maybe because the humidistat is at the front left side of the unit. This also means you can't direct the mist streams to the left which caused it to really turn off and on frequently. This really renders this unit less than useful in our large bedroom because we have a fan on overnight and this unit cannot get the humidity level to our true desired humidity level (yes, we have a separate hygrometer). It does raise it some, so not totally useless, however not to the level desired. We want the minimum of 40% and we only reached 30% after hours of running as a daytime test in the bedroom. As an experiment we used it for a tank full in another room all day with little interference from currents or people walking by with the warm mist. It was much more effective and consistent in this decent sized room and agreed with the hygrometer 90% of the time. However, when I walked by, opened the garage entry door (12 feet away) or did activity behind the unit (reading newspaper, sitting up and down, etc), it did the same inaccurate and fluctuating humidity detection causing the unit to not achieve the desired level. And as mentioned the unit can 360 direct mist, but the left front is where the humidistat is and that's not a good place to direct it. We never experienced the steam being too hot to burn us nor did we notice any water accumulation around the unit. One last thing, the cool mist was only tested a little as we wanted warm mist. We believe the cool mist had a better chance due to not using as much water and the mist didn't seem to be as disruptive in the humidity level. However, this was only a short test of the unit as the beginning and was not tested further in any detail so keep that in mind. We wanted warm mist functionality and only warm (for a bedroom) and so we are returning it for that reason.

Bra funktioner men låter för mycket efter ett par år. Det hjälper inte att rengöra

Nicht zu groß, kein Geräusch, funktioniert super

Maravilloso. Todo funciona como debe. Muy Intuitivo y con la app es fantástico el control. 10/10

This humidifier is so quiet! It is in a large room, but it’s really just for me and it’s still keeping it at about 50% humidity. I have it set on the highest setting and the tank has lasted 24 hours. Super easy to fill, either by removing the tank and filling elsewhere or filling from the top. Very happy about this purchase!

Très content de mon achat. je mets la puissance maximum ainsi que la température de l'eau car j'ai un espace important à humidifier
