LEVOIT Superior 6000S Smart Evaporative Humidifiers for Home Whole House up to 3000ft², 6 Gal, Last 72-Hour, Premium Filter, Dry Mode, Wheels & Water Fill Hose & Foldable Storage - Quiet Sleep Mode

August 2024 - This is more of a preview of my review as I have just bought this item and won't start using it until late September probably. I live in Minnesota and the air in the winter time is super dry and I use a humidifier in my 900 sq ft condo from late September until early April to battle all the issues that come with dry air. The last several years I've been using the 6 gallon Airfare humidifier and it has been a workhorse - very effective, super simple design however I've always been on the look out for a more attractive looking, more functional humidifier with maybe a little bit of tech involved and that also had a 4-6 gallon tank - very hard to find - however I think this item will fit the bill. I probably use 2-3 gallons of water in the dead of winter every day in a humidifier to keep my home humidity in the 35-45% range. My very initial thoughts on this product are - great design and build. Super simple set up. The app worked fine - it found the device and connected to it with no issue. The fan is whisper quiet on level 1 - and still very quiet on level 2. Even on level 1 and 2 the fan output upwards seem very good - moving a lot of air. I will update this review with more detail in a couple months with more detail once I actually start to use it. OCTOBER 2024 - UPDATE I have finally been able to begin using this humidifier regularly now that the weather and temps have gotten cooler and the air drier in the Minneapolis area. I am really liking this humidifier, it works well. Probably the one thing I appreciate is that the fan directs the air out of the device straight up - so it hits the room ceiling and spreads out - so it really helps circulate the moist air, in fact all the air in the room efficiently. I love the 'night mode' as the fan just runs at a very low speed all night - the display turns off and it just provides a constant level of humidity all night. I move the humidifier into my bedroom at night. The fan speed is low and there is no noise that I can hear from the fan. I'm also able to set up a schedule in the app so it goes into night mode automatically every night at 10:00 p.m. and another schedule sets it to 'auto' mode in the morning. The app also tracks the humidity level and fan speed so you can see the history of your room humidity. The wheels are a great feature but if you have 5-6 gallons of water and try to move it on carpet good luck - they just don't work - you need to grab the lip of the tank and lift it up a bit to move it on the wheels on carpet - but on hard surfaces it moves fine. Overall still like this humidifier a lot - provides a little bit of technology to a basically simple device which is what I like. The display is gorgeous and the overall look of this humidifier looks like something Apple would design. DECEMBER 2024 UPDATE We are now in the middle of winter here in Minnesota. The air is very dry. The dewpoint ranges from 0 to 20° so the outdoor air is very dry and the humidifier is running very regularly in my one bedroom condominium. This is one of the reasons I really need a humidifier with a large 5 to 6 gallon capacity otherwise I would be filling the humidifier up way too often as it is with these conditions. I’m using 5 to 6 gallons of water once every 24 to 36 hours. I’m still really loving this humidifier. It’s probably the most attractive looking humidifier on the market so it adds to your home overall look the efficiency of it and the connection to the app on your phone are great and it has been working flawlessly with no issues. As noted it uses a lot of water this time of year where I live so I do have to fill it up once every 1 to 2 days and during that time I use the opportunity to do some light cleaning on the device. Typically, I will take some Lysol bleach spray and spray it into the empty water tank area. Let it sit for a couple minutes before rinsing it out with hot water, drying it with a towel and then refilling it with clean water. I’ll also wipe down the moisture that accumulates around the top portion. One of my initial concerns with this device was that it was not using a bacteriostat treatment in the water, but I’m not seen that as an issue now as I just spend a few extra minutes making sure I clean the device when refilling the water tank. The one minor complaint I have about the device is I am noticing that when the water tank gets low, there are some droplets of water that drip from the top portion where the fan is down into the water tank so you can hear a drip drip drip sound, however when the water tank is more full, those droplets don’t have as far to fall so you don’t hear that dripping sound. This is not really an issue unless the device is near your bed. It may bother you, but if it’s in another room if not an issue when you’re sleeping I did replace the filters after two months of use. I probably could have gotten more use out of them, but I just wanted to replace them regardless and anticipate that I will replace them 2 to 3 times over a six month period in the winter months when I’m using the device. The only other minor complaint I have about the device is at times the fan speed will kick up to a very high level as it’s trying to raise the humidity level to the point it wants to, and that loud fan noise can be a little distracting however I can quickly change the setting via the phone on my app or walk over to it and change the setting to reduce the fan speed if it becomes bothersome to me, which is rare. JANUARY 2025 Well we are in the middle of a very cold snap here in Minnesota - temps in single digits and the dew point is around 0 degrees. So super dry air outdoors and the humidifier is using 5-6 gallons of water per day - I typically fill it up every night but I'm feeling cozy and comfortable in my one bedroom condo. I do feel that the 'night mode' puts the fan speed at a nice low level for sleeping however I'm not sure it is enough to properly keep my condo at the level of humidity I want so sometimes I put it on manual mode with fan speed at level 2. I'm also figuring out a good cleaning regimen every time I fill it with water - I have some Clorox Multi Surface Cleaner and Bleach spay bottle - I just empty the water tank and spray the inside of the water resovoir with the bleach spray and let it sit for a couple minutes then use my kitchen faucet hose to simply rinse out the tank and dry it quick before refilling. I do notice that at some point there is some pink or yellow build up in the middle section where the filters are so periodically I remove the filters - again, spray the plastic area with the bleach, let it sit for a minute then rinse and wipe it down before replacing the filters. This of course is normal with standing water in a device when no chemicals are used to inhibit this growth but the overall cleaning effort is minimal and it's designed in a way to make it easy to clean these surfaces. FEBRUARY 2025 - updating this again in late January 2025 as I did a cleaning session on this item and noticed some pink slime build-up in the middle plastic section - the portion that covers the water tank - there are some nooks and crannies that aren't easily reachable and I had to remove the 4 screws that hold the two pieces together that allowed me to get in there and clean it more deeply. I did notice a little pink buildup inside the hose for the water tank - I'm not sure how I'll clean that - hoping the citric acid will help remove that as directed in the cleaning instructions.

Let me start by saying this is an excellent humidifier! It does an incredible job of keeping my ~1,000 sqft. 2BR apartment humidified. I'm extremely satisfied with how effectively it will humidify my place that can get as low as 15-20% without humidification. Now, the area for improvement: The improvement could really come from Auto Mode on the Vesync app and how it integrates with the smart features of the humidifier. An unfortunate flaw with the Auto Mode is that it does not allow you to select your own preferred humidity level. It has 2 settings (home and away). The humidity level of these settings are dependent on the ambient temperature in the room as read by the humidifier, which always is about 5F degrees lower (most likely because wherever the sensor is on the unit is being influenced by the damp cooler air coming out of the machine). In my opinion, this falsely causes the humidifier to run at the 60% humidity level on the "home" setting for Auto or 55% setting for "away." Personally, that's a bit more humidity than I'd like to have in my place with nighttime outside temps in the teens Fahrenheit already in December. It just causes too much condensation on the windows. I'd prefer that I could manually "set it and forget it" on the Auto Mode at 50% and minimize the window condensation. By no means is this a deal breaker, but it's definitely an area of improvement the app developers should do to the auto mode where it's selectable by the user instead of having default humidity levels based off the incorrect ambient temperature. I have reached out to the company to see if this is something their developers could work on, so hopefully they'll be open to the feedback. Looking at some of the few reviews that there are so far, it seems like there are others that share my thoughts. The app and humidifier do have a function where you can manually select the humidity level you'd prefer and it will maintain that level. I'd liken this to a hybrid manual/auto mode. The only caveat here is that you have to set your own fan speed and it's either on or off. It doesn't cycle through lower or higher speeds to just maintain your desired humidity level like an auto mode would. I've found myself using this feature since the auto mode is just unreliable with the temperature readings influencing the auto humidity levels defaulted by the software. My Levoit 300S humidifier's auto mode setting is perfect from the Vesync app, so I'm hoping the developers will create an option for a user-selected auto mode and then the 6000S will be perfect. I still rated it 5 stars because it does everything it's designed to do extremely well. The manual does say that Auto Mode will maintain 50% if not connected to the Vesync app (which would solve all my auto-mode woes because all I want to do is set the thing to 50%) but I'm a bit of a tech geek and love data, so I'd prefer to keep the capability of monitoring everything remotely while I'm away just to ensure everything's working correctly. For anyone who made it this far in my review, don't let what I've mentioned discourage you from buying the unit. I think this could be a pretty simple software/firmware fix if it were something enough people requested and found to be somewhat problematic with the current app and humidifier settings. Even despite the auto mode issues, the app and unit itself has tons of functionality that really make it a great product! Albeit a bit expensive, but I have faith it will last quite a long time. Seems to be well-built, overall and I have not have had any leakage issues like some others have mentioned in their reviews.

I’ve been very happy with the Levoit Superior 6000S overall. The build quality of the humidifier itself is excellent — it feels sturdy, well-designed, and premium compared to many other units I’ve used. Setup was easy, and the Wi-Fi connectivity works smoothly, allowing full control through the mobile app, which is very convenient for adjusting settings remotely. Performance has been solid, and it does a great job maintaining humidity levels. Where it loses one star for me is the filters — they feel somewhat flimsy for the price, and replacements are quite expensive, which adds to long-term ownership costs. That said, I want to highlight Levoit’s customer service, especially Doms, who was outstanding. When my original unit developed a small crack on the rim of the water tank, they handled the issue professionally and sent me a brand-new replacement humidifier without hassle. Overall, this is a high-quality smart humidifier with great performance and excellent customer support. If Levoit improves the durability and pricing of the filters, it would easily be a 5-star product.

I love our humidifier. It is worth every penny. We live in an older home that felt so dry- this humidifier has helped me feel so much better on the day to day. It’s very quiet and has an app that makes it super easy to control. The app will tell you when it needs water and when it needs to be cleaned. It gives clear cleaning instructions and it is very easy to use. It even comes with a hose that attaches to your faucet to make filling the tank easy. It does a great job and is very durable!

This is my second winter using this, and I love it. Generally it does all the things you'd want in a humidifier - humidifies large areas without dribbling all over the place, does NOT put white dust on things, has some nice features. Here's some things to know, but they are not dealbreakers for me because I don't think you can avoid them: It's heavy to move after you fill it - the wheels can't handle the weigh very well, so I just shuffle it along. There is a tube to fill it with but my shower head can just reach it outside the tub, so I haven't used the tube. It's relatively quiet, but when it goes into full blow mode it's noticeable. The 'keep at 50%' feature is good, but that is often too high for my condo (unless I want to mop the windowsills) so I keep it on the other button at 40% or 45%. Sometimes it wakes up and goes back to that level a couple of hours later, but sometimes I need to quickly switch it on and off (an instant action without bending down) to 'wake it up'. Again, this is fine for me because I don't want it continually coming on and making things too wet. The feature where you can run it in dry mode to dry out the filters if you're going away for a day or so is great - I don't always want to empty / disassemble it for just a short absence. Filters that come with it are very good. Last winter I used the same ones for 4 months but they were getting a bit stinky by the end (I rinse them every week or two), so I think this year I'll change after 2.5 months and use two sets over the LONG 5 months of Ontario winter... Also the reading of the humidity level is consistent with what my Nest thermostats say, so either it is accurate or both are equally inaccurate :-)

Updated review at January 3, 2024: After almost 1 month of constant 24/7 use of my 6 Gallon LEVOIT Smart Evaporative Humidifier for up to 3000ft², I learned from the company I purchase this machine’s filters from that the discolouration - even after just 24 hours of use - is totally normal and an expected result of filtering out impurities in the water used. So that’s a relief that it’s not growing algae on the filters. Actually, after using 100% distilled water in my humidifier for this past month since that first fill of municipal tap-water, the filters have not shown any further discolouration. So no doubt the distilled water will likely extend the life of the filters, and possibly the machine as well. But….after a cost-analysis of using Distilled Water vs, tap water in this humidifier, it’s more cost effective and practical to just use tap water. It would cost me $1,700 per year in Distilled Water (as the machine is averaging 32 Litres per week). So even if using tap water in the humidifier cause more wear and tear and build-up resulting in (worst case scenario) needing to replace the filters monthly (at $107.26 CAD including taxes and delivery) and yearly replacement of the humidifier at $346.50 CAD (includes taxes and free delivery), I’d still save $70/year and wouldn’t have to haul all the jugs of Distilled Water to use in the humidifier! So I feel it’s economically worth the risk to use tap water in this humidifier, and if I can stretch the rate of filter and machine replacement, I’ll save even more money yearly. I’ll update this review if I learn anything further. For now I’m extremely happy with my cute little robot-looking Humidifier I’ve named “Robbie”, haha! ——- My original review: My 6 Gallon LEVOIT Smart Evaporative Humidifier for up to 3000ft² is already growing algae on the evaporative filter media after only 24 hours of use of this brand new machine. The humidifier was delivered by Amazon at 3:30pm December 8, 2023. I immediately unpackaged, filled it with tap-water as instructed and started it on the highest speed to see how long it could boost my humidity levels from their current 10% in my home and to see how it performs after going through a full tank of water. We’ll it sure does humidify the air really well in my 1100 square foot residence. Within just 3 hours my humidity went from 10% to 35% (I am using a separate hygrometer to determine the accuracy of the actual humidifier’s humidity gauge which does appear to be very accurate after 1 day of use at least). After 8 hours it was up to 58% humidity. It used a full tank of water (21 Litres/6 Gallons) in 24 hours of use on the highest speed by 4pm December 9, 2023. When I went to refill it, I had a good look at the evaporative filter media and it is already turning green in spots and the residual water at the bottom of the humidifier’s tank was very visibly yellow in colour. My municipal water in my city is among the very best quality water in the world (I live I Edmonton, Alberta Canada and we have award-winning water quality…and I work with water quality specialists who have confirmed this), so I observed the water was clean and clear going into the humidifier. I have since opted to fill the humidifier this time with 100% distilled water and I’ll see if it makes any difference to the algae growth I’m seeing on the filter. I bought this evaporative humidifier because of its claims to produce healthier humidified air as the filter is not sitting directly in water all the time - instead water flows across the filter and evaporates so the filter shouldn’t be growing algae - especially within just 24 hours of use! I’ll update my review when I’ve had a chance to determine if the distilled water is solving the algae growth issue with this humidifier’s filter.

The fan runs but the unit can’t draw water from the tank at all. I’ve tried every troubleshooting step — reseating the tank, soaking the wick, cleaning the base — nothing helps. The tank has no valve and the base never gets water, so it stops after a few minutes with an error. I like Levoit products, but this one seems to have a design issue. I really hope customer support can provide a fix or replacement.

We bought three of these thinking that they would be fantastic. We filled them up and plugged them in and they run for three or four seconds and then they all shut off and say there is no water. Started a warranty claim with the company, and we hope that they will refund us the money. Not good at all. *Updated review: Manufacturer’s (Levoit’s) Customer Service telephone line started the claim process. Had to email the manufacturer a video of empty tank malfunction red light icon and also the Amazon pdf invoice. Heard by email from Levoit from the claims department the next day. Agent recommended to wait for about five days for the tech department’s updated firmware available via the VeSync app. Also provided us the option to cut the cords and send a photo of the cut cords to start a replacement process. We opted to wait for the firmware update. It actually worked! Once the new firmware was installed via the VeSync app to each of the units separately, the pump did finally start to bring water from the tank below to the upper tray to drip onto the filters to make them wet and hence evaporate the water with the fan’s airflow. *Note that it is necessary to be persistent in restarting the unit several times (between 6 to 20 times, actually!) before the pump is primed and starts to deliver the water as it should. USE MANUAL MODE WITH FAN SET TO HIGHEST SPEED. (Speed 9 on the app, or 3 fan icons on the dash.) We almost gave up several times. But patience paid off. Once the pumps were finally primed in this way, the product works extremely well. The design and the build is smart and of excellent materials. The functionality is excellent. The fans are smooth and quite quiet, a gentle background white noise. It was an anxious ordeal having invested in three units at once and having none of them function, at first. Customers Service at Levoit was reasonable and their firmware update saved the day. Levoit SHOULD stipulate very clearly, though, to PERSIST IN POWERING ON THE HUMIDIFIER UNTIL THE PUMP IS PRIMED. Eventually you can hear the first trickle of water coming up into the top tray. Only then are you home free. Now we love the product as we expected we should. But it was a trying experience, to be honest. These machines raise the humidity level quickly compared to other types. We got this evaporative model after having bad experience with the white dust from the sonic misting types. Seriously, despite the initial frustrations getting it going, we love this new Levoit model with its big tank and intelligent design. Love it!

Best humidifier we've owned. Works extremely well in increasing humidity levels with no white dust, and the mobile app allows me to control it remotely. Highly recommended.
