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

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 am totally impressed. This sits in our living room (our home is about 1600 square feet) and it humidifes the whole home (3 bedroom, 2 bath and den, all one level). I set it to 50% and then set to auto and it runs like a charm, keeping the percentage in all rooms right at 50%. (It can be controlled by an app to do this on your phone but I didn't bother with that. I don't like complicated things.) It has a 6 gallon tank so you don't have to constantly fill it. I have lived in a northern climate for decades, where it's not uncommon to get to minus 10 or minus 15 Fahrenheit, and occasionally lower. It gets really dry at that temperature. I used an evaporative wick system in the late 90s but there was no way to set the percentage of humidity and I had condensate running down the windows. So I had switched to the ultrasonic white dust monsters that make me cough, with one in each room. I just got fed up and sprang for this system. I am really pleased. It is not much bigger than the air purifier I had sitting in the same place. It doesn't look out of place. It rolls on wheels right over to the sink and comes with a hose that can go from your kitchen sink to the tank to fill up 6 gallons. You don't need distilled or purified water. It's pretty easy to use. There is a casing with four black filters sitting on a platform above the water. The filters remove easily from the housing and can be rinsed under the sink faucet. They don't sit in the water, like other evaporative systems. There is a pump system that brings the water up. Not sitting in the water means you don't get all the gunky looking stuff on the wick filters like in other humidifiers. I like that you can just empty the water tank and wipe it out to clean it. They include a cleaning brush with the system and have pretty good instructions on cleaning and descaling if and when it needs that. Once it got up to the 50% after I originally set it up, the fan hardly runs. It just kicks in on low when it gets to a few percentage points below 50%. So it hardly makes any noise at all. One of the reviews described it as a "swamp cooler" but I haven't experience that at all. It seems like the normal room temperature that it was before. I am super pleased with the automatic function and am sorry I didn't buy this type of humidifier years ago. Update a day later- I went to order replacement wicks online and saw a link to wicks plus a white donut shaped filter. I didn't see anything like this in the system I have so I wrote to Levoit yesterday to ask whether my system (with the pump) is supposed to have these donut shaped filters. Big plus- they wrote back a day later (since I emailed them on a Sunday) and said that the donut shaped ones were not for my system. This is what they wrote: "The small black oblong oval piece at the bottom of the pump is the water filter sponge for your humidifier. This is different from the white donut-shaped water filters you may see online, which are for other models. The water filter sponge is optional and can be omitted if desired. Discoloration due to oxidation is normal." They went on to send me a like for cleaning the water filter sponge with vinegar, just like the donut shaped ones are cleaned. So, just so you know the Superior 6000S model with pump does NOT need the small donut shaped filters. I did also order some of the "cleaning fish" that I saw offered for the other Levoit model to help with hard water problems.

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.
