LEVOIT OasisMist Smart Cool and Warm Mist Humidifiers for Bedroom Large Room Home, Auto Customized Humidity, Ultrasonic Top Fill Oil Diffuser for Baby and Plants, Quiet, 4.5L, White

The Water Tank started to leak after I filled it up from the bottom last night. I have had this unit for about 2 weeks and it has been great and helps me sleep better. Unfortunately when I screwed on the cap and turned it over it started to leak quite a bit. Am I doing something wrong? Is it possible to over tighten? Could a gasket or something similar have fallen out? Please help. I wrote to LEVOIT and asked about getting a new gasket sent to me but that part wasnt available. Skyler was my contact and he sent me the exact inner and outer diameters and thickness of the silicone gasket. I searched and found similar but not exact gaskets and tried them to see if they would fix the leaking water. Unfortunately with water, close is not close enough. I was about to cut the gasket into 3 pieces and superglue them to the cap to seal it permanently. I knew by doing this I was going to ruin the cap if it didnt work. I asked Skyler if they could send me the whole cap. He said he would ask and a few days later Skyler said they had one and it was on its way to me. I received it a couple of days ago and I tried it out and it worked perfectly. I ran it for a couple of nights and there were no leaks!! I find that I sleep much better when I have the LEVOIT Humidifier running. Thanks to Skyler and LEVOIT!! Excellent customer service!!

Humidify working but unable to connect to WiFi for wireless/voice control

This is a review of the following product on Amazon: LEVOIT OasisMist Smart Cool and Warm Mist Humidifiers for Bedroom Large Room Home, Auto Customized Humidity, Ultrasonic Top Fill Oil Diffuser for Baby and Plants, Quiet, 4.5L, White Product Information states: Floor Area 430 Square Feet • Fast Relief: Using VortexMist Technology, the OasisMist can increase room humidity by 10% within 15 minutes with up to 430 ft² room coverage. Perfect for bedrooms and large rooms • Healthier & Reliable Mist: Run your warm and cool humidifier for up to 45 hours with low cool mist. The mist output can be up to 550mL/hr and the 4.5-L tank capacity also makes it perfect for bedrooms and large rooms. Under Specifications: Effective Range: 215–430 ft² -------------------------------------------------------- My review is based on the effectiveness of the OasisMist in a 286 sq ft room with an average height of 8.5 feet which equals 2431 cubic feet of volume space. Volume is what has to be used to determine maximum effective capacity of a humidifier, NOT square feet of a room. For the purpose of comparison and evaluation of effectiveness, let’s assume the advertised 430 square feet Levoit states is for the shortest room height of 8 feet. Thus, the volume of maximum capacity it can service is 430 x 8 = 3440 cubic feet. Under specification Levoit states an effective range of Effective Range: 215–430 ft². The lower end obviously accounts for heights higher than 8 feet and possibly other features of a room, such as windows to the outside, that would affect the effectiveness and maybe the introduction of heat on and off during the night. We turn out heat down do 64 degrees F before retiring and the heat may go on about 1 hour before we get up. But, two of the sampled nights were when the outside temperature during the day heated the house where at bedtime it was still at 70-71. Also, most of the observations below were made before any heat was introduced. In summary, the base is a 286 square foot room with a volume of 2431 cubic of air and no heat was introduced. For 4 nights using this OasisMist I found that no matter how it was used, i.e., manually or automatically, I could not get the humidity, as indicated by the display (another matter to discuss) above 61. If you read the User Manual re Automatic mode, you will see it has a default of 60% before it turns off Automatic mode and returns to a lower setting (not explained what it is). If you install the VeSync application (another discussion below) you can change the default (if you set up Voice controls), which I did last night to 65%. I have a medical condition that recommends a minimum of 60% humidity during the night when sleeping, thus, this is my expected requirement for any humidifier. The OasisMist FAILS to meet my requirement reaching on 57-58% after 7 hours of running in Automatic mode, and just reaching 60-61 for 15 minutes once in manual mode on high mist setting. Conclusion: The OasisMist cannot even effectively service a 286 square foot room (2431 cubic feet). My room is about 70% LESS THAN LeVoit’s marketing statements. Humidity Display: I was attracted to the large numbered display that reports humidity. Other reviews mentioned that what is displayed is no where close to actual humidity in the room. How can a sensor in the unit measure humidity in a large room, say, 10 feet away? It can’t without creating an approximation with some algorithm. What you see can only be the actual measurement of the space in close proximity. But, this isn’t the issue that concerned me the most. Despite the humidity display, you CANNOT CONTROL the OasisMist by manually setting the desired humidity and can only change the default point when Automatic Mode with shut off when in Automatic Mode. The OasisMist operation is only manageable by the MIST output, i.e., settings Low, Medium, High. If you need quick introduction of humidity turn on Manual mode and set the MIST level to high. Both output vents will shoot out cool mist. Can you realize 10% increases every 15 minutes as stated in the product information above? NO! It took my unit about 4 hours to increase 15% on High mist level. Now, note that Automatic Mode controls the levels automatically, NOT the actual humidity. It will start out at High mist level and based on the table in the User Manual, drop down to Medium and then Low based on the reading it senses. Just to be clear: You get to manage humidity ONLY by changing mist levels! VeSync Application: You really want to set this up with Voice control. The instructions are not close to being close to do so though and some ingenuity and experience with mobile phone and either Alexa or Google applications are required. VeSync does excellently connects to your router (be ready with your password) and connects to Bluetooth (prompts nicely to get the job done). Now you need to define your device, I called my humidifier Bob, to VeSync and it connects via Bluetooth. If you follow the instructions, you might think you ready to use voice after following the instructions. However, you have just established in my case that Bob can be controlled by VeSync. Left out is that if you are using Goggle “Hey Goggle” commands, Google must be set up too to link to your VeSync application. So, you need to ensure you have Google assistant from Google Store, go into assistant and establish voice for VeSync by linking to it. Once BOTH Google and VeSync are set up, the “Hey Google” command for Bob (my humidifier name) with flow from Google to VeSync which will pass it on to the unit itself. It really is spiffy. Now the rub. You ask why do I have to use voice. The only specific reason is if you want to change the 60% in Automatic Mode to a different default, like 65% that I used -- no other way to do so. Other Features: • I love the size and design of the OasisMist. The use of the removable basin that has a handle is priceless. The tank hold 1.1 gallons of distilled water which is not that heavy to insert into the unit onto the base. Slick. • The controls are well designed on the front panel and so easy to use. The access to the filters (water and mineral absorption) is simple and convenient. • The use of VeSync application to set up a time schedule for operation allows the obvious on/off at a time, but also lets you set up modes and mist levels. A separate Timer is provided that allows you to turn the OasisMist off after a set period of time. Once again, VeSync is a must have to simplify controls even more than the physical panel controls. • I didn’t use the Warm mist, so I can’t comment on it other that two vents are on the unit. One is used for the warm and one for the cool mist. However, the Warm mist vent is preempted if Cool Mist is set High in which case cool mist comes out of both vents. • It is completely silent – to me who has a hearing deficiency that is. My wife who was closest to the unit heard only a drip every 10-15 seconds. • Filling and cleaning is a breeze. My Rating for this review unfortunately must heavily depend on whether the OasisMist met my expectations of effectiveness given the marketing information stating it will. Since it didn’t come close, I have to basically ignore all the other great features. Maybe it should be rated a 1 because it did not meet expectations as defined, but in a smaller room it would probably be a 5 after the VeSync is operatable. So, I’ll choose a 3 to denote a caution to users who are looking at this for a Large room and to get their attention to point out the very positive features listed above.

Though I do not feel aroma oils, all the product design, UX/UI design, app connectivity, and functionality are awesome!!!! I’ve struggled with washing humidifiers and refilling waters in them, but I like this top-fill and easy to maintenance humidifier!!!

I use this humidifier to keep my plants happy and it seems to be working. If you want to hear it, you have to put your ear right next to the motor and stop breathing. The display agrees with a digital hygrometer I bought separately, so its at least that accurate. Ive had other cheap humidifiers from the pharmacy that are garbage next to this one. If you love your houseplants, its worth the price. After a month, I finally got the app that you will need if you want the humidity to be above 60. The app is meant to control all manner of devices you may or may not have (which I dont), so it is a bit annoying, but thats just old Luddite me. I have been filling it with tap water even though purified or distilled water is recommended, but who is going to do that unless they have access to a huge reservoir of purified water? People that only use it when they are sick? I guess I could lug some reverse osmosis water home from the lab, but no. I havent yet noticed any lime deposits on my walls. What I have noticed is an increase in tiny flies in my apartment. I find them floating in the reservoir of the humidifier, so Im pretty sure theyre attracted to the humidity. I dont know how to deal with them yet. I clean it once a week and refill it in between cleanings. And though I havent changed any filter parts yet, I definitely recommend this humidifier despite the app and the flies. It is the best humidifier Ive ever had.

I looked through EVERY humidifier on Amazon searching for one with warm mist that wouldnt send humidity right up into the air only to have it immediately fall back down into a puddle on the ground (been there/done that!). I finally settled on this one and bought it and I LOVE THIS ONE. First of all, it is easy to fill. Top filling. No more filling a tank and carrying it to the humidifier and having to flip it upside down to insert it into the machine! Also the carrying handle is well-placed making it well-balanced. You dont feel like its going to tip frontwards or backwards. Second, when you pull it out of the machine, there is very little excess water that will drip when youre carrying it to refill it (if thats what you choose to do. I just use a pitcher but you do you). Just a dab of a paper towel and youre good to go. Third, this thing cranks out the moisture - in a nice vapor - that then somehow actually gets absorbed into the air (wonder of wonders!) and does not rain right back down onto my laminate flooring!!!! Lastly, its quiet, and it runs for quite a while on a full tank on high (around 8 hours or so?). Just buy the dang thing!! I truly do love it!!

Ive owned around 5 different humidifiers in the last 30 years. This is one is by for the best Ive ever used. I use mine in the bedroom to help with dryness and allergies. It is extremely quiet. If you are awake in the middle of the night you might hear an occasional brief but very quiet gurgle (air bubble). Set the desired humidity level and it will cycle on and off to keep it there. I have mine set at 55% humidity and it seems perfect for me. Mine runs around 10 hours a day and I have to refill it every 5 days or so. I use reverse osmosis filtered water and there is no musty smell in the tank. Ive been using it 4 months and hope it lasts. I did purchase the extended warranty through Amazon just in case.

This is WAY better than the Canopy humidifier I had (what a piece of garbage). Like all humidifiers, I wish the cleaning obligations were less burdensome but it is what it is. Mostly, this is a great product & im happy with the purchase. The only thing I wish were better is the diffuser. I really don’t smell anything in the bedroom I use this in. The manual does say not to expect a strong scent but I don’t smell anything at all.

My last humidifier was just too gunky to use anymore, as its impossible to clean the tank. Vinegar just doesnt do it. The auto feature on the Levoit will shut it off when it reaches 60% and I can see why. I ran mine at the highest mist setting and it was getting to 69%, but the carpet nearby was getting damp, (The unit sits on the corner edge of my dresser.) I have an Airthings sensor across the room from it and it read as high as 63%, so this thing does do the job. My bedroom is 14 by 14 with a 13 high ceiling. I looked at the APP and dont see it even worthwhile to add another password to my black book. Some Internet gadgets are okay, but most things will include a remote if its worthwhile to have one. Theres hardly any adjustments necessary for the humidifier; just press the A for auto mode and forget it. Neither do I see a need for a Sleep function as you cant hear it running anyway. Just hit the A and walk away. I like how easy this will be to clean, unlike my last one. Theres only a few areas in the lower part under the tank where youll need the small brush they provide, but at least you can stick you hand in the tank to clean the sides and bottom. I saw people complaining about the white dust from minerals. You should NEVER use tap water as you are breathing this stuff. Also, do NOT put alcohol in the water to sanitize it, not even drinking alcohol, as breathing it you will super absorb it into your bloodstream, and thats NOT a good thing. I installed an under the counter Reverse Osmosis unit that removes all the minerals and other things, and use this for the humidifier. So no white dust problem here. Buying distilled water is too expensive for daily use. It would be more economical to install a filtering system that lasts a lifetime. (On a side note, Las Vegas recycles their water and it tastes horrible, so I distill the water from my RO system to make it drinkable. Particle testers show the water particle levels after distilling are too low to read, so now I feel its safe to drink.)

This humidifier exceeded my expectations. It’s such a nice product and I’m so glad I splurged and bought it. My sleep quality has improved drastically and I LOVE being able to control it from the app. At first I was going to buy one with a remote but so glad I decided to try this model with connected app. I’ll admit that for the claims this device made, plus the higher price point, I was skeptical. After unboxing and getting it going, I was feeling good. After the first night of sleep, second night, third, I really started to notice a difference in the quality of my sleep, my sinuses and my snoring. I live in the Midwest- the harsh and dry winter air is killer. This humidifier has made my home easy to breathe in! Finally I found a humidifier that lives up to the claims made! I do notice some slight leaking once in a while but I’ll be honest, the leaking isn’t bad at all and if that’s my only problem then I don’t mind. For the perks it provides, I’ll gladly wipe up a bit of water once in a while. Just make sure to keep it clean and away from kids/pets if using the hot mist function! The cool mist works great for us but love the option of hot OR cool! or BOTH at the same time!
