Levoit Classic300 Ultrasonic Top Fill Humidifier, Extra Large 6L Tank, 60H

I’ve owned this humidifier since November 2023 and it’s still going strong! I live in a small, one bedroom condo and keep this in my bedroom and it humidifies the entire place. I use only distilled water in it as the tap water where I live is very hard. Distilled water makes the cleaning very easy as I’m not cleaning up build up of minerals or scaling, just cleaning any bacteria that builds up over time. Since I do not need to use the included water filter, I remove the part that houses it which equals less things to clean. I also do not use the little felt pad because we use distilled water. I haven’t used the aromatherapy pad. The top fill is a game changer and makes replenishing water so quick, easy, and hygienic. I use to hate flipping my old humidifier over to unscrew the wet cap and then flip the full, heavy reservoir onto the base. Overnight, I go through about a gallon of distilled water. If I’m home during the day I typically go through 2 gallons (one during the day and one overnight). If we get particularly cold weather then I will go through maybe 2 1/2-3 gallons in an entire day as the forced air heating runs more frequently. If the weather isn’t as cold, a gallon of water could last 2 nights or more, and one gallon would suffice for an entire day. I will say that the humidity reading is off by about 15% in my case, so I have to set the target humidity higher so that I get to the level I actually want, not lower. It’s not a problem once you tweak it to give you the humidity you need. I also set the warm mist level to high as I believe the warm mist is much more effective and beneficial than the cold mist. It is quiet. With the warm setting set to high you do hear a “simmer/boiling” sound however I do find that sound to be soothing, like a pot of soup on the stove. I use the app to control it and set it on a schedule. I love that I don’t have to remember to turn it off before I go to work in the morning. The app is very user friendly and even has additional features like plant care. I’ve added every plant I have to the app and it reminds me when to water and fertilize them which has made my black thumb a bit greener! My plants are thriving thanks to that feature. Whenever this device decides to give up, I will buy the same one again. I’ve recommended this product to anyone who asks. It really saves my sinuses in the dry north east winters. And it really saves my husband’s skin, he suffers from eczema. No more nose bleeds and no more eczema break outs! Comfort in the dead of winter. Buy this!

I have two of these and a Pure Guardian H3200WCA. I like the Levoit much better because the water tank is very stable when filling it where the Pure Guardian must be balanced as the filling port is on the opposite side of the curved tank. I had to roll a towel up from two edges to form a trough to hold the tank steady. The Levoit has a flat top and bottom. You turn it over and remove the lid, pour in the water and put the lid back in. The only drawback is the Levoit has blue lights that cannot be shut off, which makes it harder to sleep if this is used in a bedroom. A final comment the Levoit has yet to grow the red bacteria found in my area where the Pure Guardian seems to be a breeding ground for it. The bacteria is harmless but does require cleaning to avoid a slime build up. Over the two weeks we have had this unit the aromamizer fan became noisy and when I tried to disable it I found that Levoit does not build their products to be repaired. Three of the screws were conventional Phillips the third, buried deep in a hole, proved to be an number 15 Torx. Now the only sound is from the hum of the power supply and it was muffled by stuffing 1 1/2 cotton balls into the aromamizer port. I am a strong supporter of requiring products to be built to be serviceable by the owner. As an IEEE Fellow and amateur machinist I feel it wrong to make me spend $200 to fix something I could fix is 15 minutes. Boo! Levoit. But it is a good humidifier:-) Six month update: We bought a second one to keep up with the cold, dry winter. It is easy to fill, which is good given the number of gallons we run through it a day. Both units have a strong tendency to race the fan motor just after filling the reservoir and make a lot of noise. A few whacks to the side solves the problem. If the unit had a filling port on top it would be easier to fill and the fan probably would not get into the race condition. Update: The solution to the race condition is to unplug the unit when filling it. Do not use the on/off key because the unit runs until the water inside the unit is exhausted. If unplugged the water level remains and when restarted - no race noise! It also helps to add water to the base before putting the tank on. Update: The original units are getting too noisy, but because they are so easy to use and effective be have bought two new ones that appear to be slightly different. No motor racing noise yet but a high pitched hum has forced us to move them to more remote locations in the house, where they work fine and keep the house at 40% humidity. Update: Had trouble with one of the valves in the tank. Called Levoit and a new cap with valve was sent promptly. No hassle at all. Update #2: They have been in continuous operation for about 8 months, putting about 4 gallons of water into the air every day. No problems, but we did notice that initially there was red growth growing on the bottom side of the tank and the top of the base unit. We rinsed the surfaces with near-boiling water and after three rinses a week apart, the problem was gone. Still have to clean it periodically though. The red stuff is probably a bacteria, Serratia marcescens, which likes moist environments. It can cause infections, so keep it under control if you get it. We're still loving the units we got in 2018 and finding the tanks from the 2017 units useful as we keep them filled and swap the tanks, then refill at our convenience. Levoit should consider selling spare tanks.

Bought this humidifier based on NYT Wirecutter recommendation. My bedroom is particularly dry over the winter time, so I needed something to bring the humidity level up. This humidifier works great. Easy to set up and run. My bedroom is about 12 x 15 with a cathedral ceiling, and the machine successfully raises the humidity from 30-35% to 45-50% and keeps it at that level over the 8 hours I'm sleeping. I fill the tank with a gallon of distilled water, and I'm able to run it about 2 nights before the water runs out. The noise level is noticeable when it is on, but not very loud. I usually run a white noise machine at night anyway which completely covers any sound the humidifier makes. I do recommend using the heated steam setting over the winter as it seems to make the room more comfortable. As for cleaning, I've had the humidifier about a month, and I've just been emptying the tank every 2 days, taking it apart (which is quite easy), wiping down the parts with a microfiber cloth, and then letting it air dry over the course of the day. That seems to work well. I do plan on doing a deeper cleaning after a month probably following the recommendations made by Wirecutter for how to do that. You have the option to use essential oils if you want to try aromatherapy, however, I've not tried that, and I'm not sure how healthy that would be for overnight use. You can use an app with the machine which gives you better control over the machine (like finer grain control of humidity settings and options to turn off display), but it's not required. It is pretty easy to set up, and I like being able to use the app on my phone to control it from bed when needed. If you need a humidifier, I highly recommend it.

I really love this unit. It is the best humidifier I've had. The fact that it can maintain a set humidity level relatively accurately is a huge asset. I live in the southwestern US and it is very dry here, and I am also a musician. Having recently purchased a very nice acoustic guitar made of all solid wood, I wanted a humidifier that would keep my apartment at a stable humidity level ideal for an acoustic instrument. This unit does the job but requires some extra steps to make it truly work for me. I've found that under normal operation, the humidifier will run until the internal hygrometer senses that it has reached the target humidity level. Once it has reached the target level, it will stop until the relative humidity drops to 5% below target and then it will run again. However, it will often linger around the target level (according to the display) when it clearly feels dryer than what is being displayed. Now, I have yet to test this with another hygrometer (I need a weird battery for my other one that I have been too busy/tired/lazy to buy), but other people have and they have noticed that the displayed RH% on the Levoit unit is about 10% higher than on another hygrometer. What I have noticed is that if I run a fan in the room, the displayed RH% drops significantly, and then the humidifier is outputting quite a bit more mist and at this point I feel that the RH% on the readout matches what I feel in the room. This is consistent with other reviews. My belief is that the humidity sensor on the Levoit unit is not that well designed. It seems to be fooled by the mist around the humidifier into detecting a higher-than-accurate humidity level. This is easily remedied by running a fan near the humidifier to encourage airflow. About the aroma pad (IMPORTANT!): I DO NOT recommend using the aroma pad. I was really excited for this feature and it plain doesn't work. Levoit says aroma should be "light" and I would agree if you put your nose right up to it, yes, you can smell a light aroma. It does nothing for the room. What it does seem to do is further confound the humidity sensor, making it impossible for the unit to reach anywhere near the target humidity. At one point, I noticed I was getting no mist output for some time after applying oil to the aroma pad and inserting it. I removed the aroma pad, and the readout RH% dropped like a rock! The sensor is right in that area where the aroma box is, so I just bought a separate ultrasonic diffuser to make my apartment smell nice. Other than the aroma box/humidity sensor issue, this is actually a fantastic unit. Very easy to clean, easy to fill and the big reservoir can last a while. If I need to take a trip and I'm gone for a few days, it will keep my apartment humid enough that my guitar is happy. The mist output is strong, and the two rotating nozzles really spread it around. I've heard also that a separate smart-home hygrometer connected to a smart outlet can regulate the unit's output if the unit is set to manual, which would then make it a perfect set-and-forget humidity solution.

An elder relative needed a humidifier for a large room and I looked at a lot of them here at Amazon. I've used many humidifiers in the past, and thus know quite a bit about them. Eventually, I decided on this one, even though it's pretty expensive, and I had never even heard of the Levoit brand. It was a good choice, though. It's easy to fill, easy to clean, turns itself off when empty, and has a very useful and easy front menu screen. There are three mist speeds to choose from; the choice of cold or warm mist, with three heat selections; an auto mode where the humidifier will turn itself off and on depending on the humidity level; a red low water symbol, etc. So far, the warm mist has only been used for one cold night on the second heat setting. It didn't seem to make any difference to the room temperature, and I think it didn't work as well as the cool mist, so only the cool mist has been used since that time. (Hard water tap water is being used.) The level choices are good, and the two top nozzle vents can be turned in any direction that you want, or in two different directions. It is very easy to fill, but is very heavy when filled. (My elder relative would not be able to fill this even halfway and flip it, due to the weight.) There is no top filling, either. I didn't know why at least one of the reviews stated there was, but then saw there are two different humidifiers being sold on this page. (My review is for the black one that does not connect to Wi-Fi.) The hydrometer reading on the screen always either exactly matches; or is one, two or three numbers off; the reading of a ThermoPro hydrometer that is in the room. All in all, it's one of the best, if not the best, humidifier I have ever seen. P.S. The amount of time a tank of water lasts is nowhere near what the description states. On the lowest mist level, it has to be filled at least once a day. The auto setting has never been used, however, so I don't know if that would make any difference. P.P.S. 12/11/21: In the second winter with this humidifier. I think it's the best one I have ever bought. Cleaning and disinfecting it can seem like a chore, but it's really not that much work. I actually don't do it that often, but do smell the mist to make sure there is no mold smell. Talking about smell, I put peppermint oil on the essential oil pad for the first time this season, and there is very little peppermint scent. Maybe that only works when using warm mist, something I think is not helpful at all. Cool mist does the job, and is safer because there is nothing heating up and staying hot. Highly recommend this humidifier!

Love this humidifier. I moved to a very dry climate after living all my life in a very humid one. I knew I’d need this, because on prior visits I’d found it difficult to sleep (I have a cpap with a humidifier but the thing would completely drain in the middle of the night even on the lowest setting with how dry my area is). With this humidifier, I sleep very well. My cpap doesn’t completely dry out overnight. It keeps the humidity level comfortable for me. I like the ability to set a timer and to switch between cool and warm humidity. I very rarely need to use it on a high setting, so one tank full gets me through a couple nights. Which is nice because naturally it is a bit heavy to lift when full. I haven’t had any of the issues other people have mentioned in reviews. Apart from the rubber gasket slipping and leaking once, but that was easily fixed by replacing it back where it should be. It’s not tricky to clean either. I use reg tap water for the tank, and while there is a bit of a residue left on the outside of the tank and surrounding areas from the high mineral content, it’s not enough to bother me and is still fairly easy to clean off the machine and surrounding area. I don’t have it placed on the ground or on a wooden table. I don’t recommend that. As the mist will still land on surrounding areas. I had it on a glass table for some time and the water did leave a white residue behind, but it was still cleanable. However I found a little metal stand for it and that works best for me. I could avoid the residue with distilled water, but I prefer not to buy so much plastic bottled water, even with how inexpensive it is. However it is an option others might be fine with. I’d rather clean a little more often than go through so much plastic. The inside of the tank is easily cleaned with a little soap and water too. Haven’t had any problems with smell or mold in the six months or so I’ve had it. I run a little diluted plain vinegar or lemon juice through occasionally as well. I LOVE the ability to turn off the display. This was a must for me when deciding what model to buy. We have far too many electronic things in our lives making every room glow in the dark. I like it dark and quiet when I sleep. And I can honestly say this machine is also fairly quiet and fits the bill for not glowing brightly all night The little remote is nice too. No need to get out of bed to adjust anything or turn off the display. All in all the device fits my lifestyle perfectly. I recommend it as a good product to invest in if you’re needing more humidity in your home.

Love them. Use them everyday. Live in a dry desert and wood furniture was shrinking and cracking. These maintain proper humidity. We use two for a 2000 sqft house. Daytime in the living room. Night in the bedroom. It requires half a gallon of DISTILLED water per unit per day.

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

Very good & nice product,

Nicht zu groß, kein Geräusch, funktioniert super

Amazing purifier. Being smart is definitely worth every penny as you just need to adjust it once and it will do the trick

Utilizo humidificadores desde hace años y este modelo me ha encantado, tiene buena potencia, es super silencioso, tiene gran capacidad de agua por los que dura las 24 horas sin problemas. Lo recomiendo
