LEVOIT LV600S Smart Warm and Cool Mist Humidifiers for Home Bedroom Large Room, (6L) 753ft² Coverage, Quickly & Evenly Humidify Whole House, Easy Top Fill, App & Voice Control - Quiet Sleep Mode

I'm writing this two weeks after purchasing my first of two of these new humidifiers from Levoit (I was so pleased with the first unit that I quickly ordered another during the Prime Day promotion). So far, so good.EDIT: Please note that this review ONLY pertains to the new, 10L model (the tall, skinny model). Some of the other reviews on here make mention of features (or lack thereof) for a different size model, since they are all grouped together on this one product page.I have been super impressed as they have a significant tank capacity while maintaining a relatively small footprint on your floor wherever you position them — about the same as much shorter humidifier units that they have replaced in my apartment. After having a wish list for years in what I was looking for, in the perfect apartment humidifier, this checks nearly every box. As mentioned, the 10 liter water tank capacity is massive, so there is far less frequent of a need for refilling. There's also a clever 360 degree rotating spout on the top, where the mist is projected out and into your room. This is great if you want to position the unit in the most aesthetically pleasing way within your space, but actually need the mist angled towards another, particular direction. The app connectivity is what I would say completely puts these into another tier versus other humidifiers I have owned over the years (of which there are many).In the app you can set up all sorts of automated routines as well as my most-preferred Auto setting. With this, the machine will intelligently turn the mist on and off, in addition to being able to throttle the amount of mist being projected, in order to maintain a target humidity percentage within your space. This can be set as high as 80% relative humidity, which is a lot higher than other auto settings I have seen on other humidifiers. If an auto setting would only allow for 60%, for instance, that wouldn't be high enough for my needs.This is actually why I feel like the unit is best suited for people maintaining a lot of plants (or simply requiring consistently HIGH humidity). Since you can set the auto setting as high as 80%, you can easily and effectively create an ideal environment if you're a big tropical plant enthusiast, as I happen to be. Furthermore, because of being able to use the app to control and monitor your humidity levels, it makes for an excellent solution for people who travel and need to maintain proper levels for their plants. I can't even begin to explain my past stress over what will happen to my plants if I had a week-long trip for work or leisure, when I knew that the humidity levels in my apartment would drop like a stone within a matter of two to maybe three days. With these units you can monitor and hold a decent level of humidity far longer than with anything else I have ever seen or tried. This peace of mind is really valuable to me.There is also Alexa support for voice commands, which is a nice plus. Again, this just checks off so many boxes that I wasn't sure I was ever going to find in one singular humidifier.The process to clean the unit seems easy enough, which thankfully I won't have to do quite as often as suggested. I only use water that has been purified from ZeroWater filters/pitchers (that remove all TDS/total dissolved solids from your tap water). Highly recommend going this route too — you will need to clean your unit a lot more often if you are using tap water!My only complaint is that I wish that the AC power cord was removable from the unit, so that you could more easily take the water tank and clean it without needing to worry about the cord as an electrical component. Plus, then you could take the unit and clean it more easily in, say, your bathtub. This is the only thing that I can possibly think of that the humidifier doesn't satisfy. So, it still deserves a five star rating for my needs.

Do I get sick in the wintertime anymore since using this? No. In two years, I got sick once. My house gets so dry in the cold and this does an amazing job of keeping my airways feeling normal. I sleep better and wake up feeling better. It’s so quiet, I love the nighttime mode because I hate all light in my room. I love the ability to control it from the app. It holds a ton of water so it can keep going for a while. And it’s been years and it’s holding up. Super durable, easy to clean. I bought some more filters to use with it because my water is fairly hard and those help keep things running great. I literally don’t know why I waited so long to get one of these. I want one for every room, my office, my car, hotels I sleep on. Everywhere. I want it everywhere.

I bought two of these units in 2023 and they are still highly functional. I had a part breakage and contacted Levoit, they were awesome! I also purchased and extended warranty, which they honored. They asked that I take a photo of the broken part. I took images and provided Levoit with a PDF that contained the receipt, date purchased and they replaced the unit - no issues. That's amazing service. I am now a loyal Levoit customer. By the way. To extend the life of the units, I only use filtered water, which is healthy for your body and humidifier. Thank you Levoit!

I'll state the pros first:* Looks nice and sleek.* Love the viewing window to check water level and the fact that it goes almost all the way to the bottom of the unit.* Humidity sensor seems more accurate than most models I've tried. Still off by about 7-10% compared to external humidity sensor but a couple of units I've tried was off by as much as 20-25%.CONS:1. Top of list. If you set a target humidity level the unit as well as VeSync app does NOT allow you to also set the mist level! This is an absolute show stopper and I've already told Levoit they need to change this design ASAP.2. Further to #1 above. This unit is designed to output LOW mist only when it gets within 5% or less of target humidity. END RESULT: it NEVER reaches the target humidity even inside a room which is far less than it is supposed to be able to handle! The low mist setting is simply NOT enough to do more than maintain current humidity so it is stuck at 4-6% BELOW the target humidity. It literally NEVER stops running because of this.3. If I set it on manual I can control the mist level and it is able to reach the humidity I want with no problem. BUT then that defeats the whole purpose because I am not about to accept having to turn this thing on and off manually all day long.Now compare this to the Levoit LV600S humidifier. On that unit you can set BOTH target humidity and mist level and as a result it is able to reach target humidity with no problem. BUT the problem with the LV600S is that the humidity sensor is wildly inaccurate. It gets into these modes where the humidity keeps going up even when the mist is OFF and sometimes goes DOWN when I turn the unit back ON! I tried 2 different ones of this model and BOTH have major problems with the humidity sensor which is why I decided to give Levoit one last try and got this 1000S model. Then of course I ran into the problem described above.This lack of not being able to set target humidity and mist level both have dropped the rating down to 2 stars! If not for this problem I would have probably given it 5 stars. That is how critical this problem is! I find myself doubtful that Levoit will fix this and if they don't they will permanently lose a customer and I will never purchase another of their products again.I will happily update this review and change my rating if Levoit fixes this SOON before I just give up and return this unit to Amazon and search for another brand.Are you listening Levoit?UPDATE: OK I'm raising the rating to 4 stars because Levoit came back with a workaround using SCENES in the main part of the VeSync app so that humidifier can be left in manual mode at highest mist level and be turned off and on via the scene. This works, however there is still a problem with the humidity sensor with Levoit humidifiers in general in that they sometimes becomes wildly inaccurate. I have multiple humidity sensors and the only one that has problems is the Levoit humidifier. Here is the issue: it seems to me that Levoit's humidity sensor needs to have some minimum amount of airflow around the aroma box in order for the sensor to be even remotely accurate. I keep my office door closed so it does not try to humidify the entire upstairs area and granted this does reduce airflow to a degree BUT again only Levoit has this problem. It gets into this mode where the mist is OFF and the humidity continues going up even though THREE other sensors start going down at the same time. Then when the mist turns ON the humidity starts going DOWN and then at some point it slowly starts going up again. If I simply open the office door after several minutes the humidity sensor starts mostly behaving itself.But I should not have to keep the door open and again the fact that only Levoit sensors have this issue tells me that this is a Levoit issue which needs to be fixed.Unfortunately I cannot keep this humidifier as leaving the office door open all the time is not an option.I can recommend this humidifier for people who don't keep the door closed in a relatively small room (less than around 175 or so sq feet) because the airflow in a larger space would probably be OK. Smaller spaces with somewhat less airflow causes problems with the Levoit sensors.To Levoit: Please, please redesign your humidity sensors to make them more reliable.

We bought this humidifier after all the ones we had owned stopped working. This is a terrific product and we immediately went out and bought a second one. It is quiet, effective and doesn't get clogged up with mineral deposits the way other humidifiers have. It is worth the extra $ it cost as it will last a whole lot longer than others.
