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

We bought the LEVOIT Superior 6000S Smart Evaporative Humidifier specifically to support our xTool apparel printer, and it’s been an excellent addition to our setup. Consistent humidity is critical for print quality, and this unit keeps our space perfectly balanced without over-humidifying. Coverage is impressive. It easily handles our large workspace and keeps humidity stable throughout the day, even during long production runs. Being evaporative is a huge plus. No white dust, no damp surfaces, just clean, even moisture in the air. The smart features are genuinely useful. The app makes it easy to dial in the exact humidity level we need and monitor everything at a glance. It runs quietly in the background, which is great when we’re working for hours at a time, and the large tank means far fewer refills. If you’re running equipment that depends on controlled humidity like apparel printers, lasers, or electronics, this humidifier is absolutely worth it. Reliable, powerful, and well designed. We couldn’t be happier with it.

The Levoit Superior 6000S has been a great humidifier and a noticeable upgrade from other models I’ve used. The biggest advantage is not having to buy distilled or reverse osmosis water—it works perfectly well straight from the tap, which makes daily use much easier and more convenient. It does a great job maintaining comfortable humidity levels, and the smart notifications are very helpful. I like getting alerts when the water tank is empty, so it never runs dry unexpectedly. The filter has also lasted a long time before needing to be replaced, which has helped keep maintenance costs down. Setup was straightforward, operation is quiet, and overall reliability has been excellent so far. This is a well-designed, low-maintenance humidifier that performs exactly as advertised. A great choice if you want strong performance without the hassle of specialty water.

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 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.

This LEVOIT humidifier is amazing for my whole house! The 6000S model covers up to 3000 square feet easily. The smart features work great with the app - I can control it from anywhere. Super quiet operation, even on higher settings. The evaporative technology is efficient and healthy. The water tank is large and easy to refill. Perfect for dry winter air. My family has noticed better sleep and fewer dry throat issues. Highly recommend!

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.

So far, so good. I've used this for a few months and it's effective. In the very dry climate I live in, this product has enough capacity to properly humidify large areas. At medium fan speed, it's quiet enough to be unobtrusive, while at the highest setting, it is loud enough to be obnoxious, if you're in the same room. We generally leave it on the highest fan speeds at night and when we're not in the area. The results have been easily noticeable: I don't have the dryness, irritation, and inflammation in my sinuses, and my eyes and lungs feel better. I have taken points off for two reasons: 1. The casters are cheap and barely effective. This might seem minor, but when you're moving 6 gallons of water around, you want something that rolls and moves smoothly. This is a major design flaw. It's not that they don't work, but they are stiff and clunky. It's hard to rotate them: So much so that you have to push with enough force that the tub can slide or scrape across the floor, or even try to tip over, before the wheels will rotate in the correct direction. 6 gallons of water weighs over 50lbs by itself, so this isn't a trivial detail, particularly if you're older or have a disability. 2. The algorithms that control the various "auto" modes seem inscrutable and buggy. According to the manufacturer's documentation, when the product is set to "Auto" or the percentage target modes, certain fan speeds will be used to achieve the targets. For example when far from the target, the fan will operate at the highest speed. As you get close, it goes to medium, and when you reach the target it operates at the lowest fan speed. While this seems reasonable, the fan doesn't appear to follow this. Sometimes it will seem to get "stuck" on high, even when it has already reached its target humidity. Other times, it will shut off completely (in percent target mode). And when the fan speed lowers, the humidity read by the sensors reads much higher, since it's not circulating the surrounding air through it. It's a terrible design flaw. I've seen it completely turned off, showing a reading of 45% humidity (the current target), and when I manually switch the fans back to full speed, the humidity drops by 10 percentage points, since it's now circulating that actual air. There are no issues with leaking, and currently maintenance seems to be relatively straightforward. We will see if it stands the test of time. If they would fix the design flaws, I'd give it a much higher rating, as it seems like a fundamentally good product.

I've owned many humidifiers, and this ranks easily as the very best. It effectively humidifies 1000+ sq ft, is easily controllable via the smart app, and requires minimal maintenance. Sure, the filters have to be changed periodically, but this is true of any quality humidifier - I don't count that as a negative. I love that the tank holds enough water to last at least 3 days even in the driest environment, and the smart app allows easy convenient control. In summary, this is no doubt the best humidifier I have ever owned. Now, the negative.... The fan has 2 speeds: "low" and "hairdryer/vacuum" high. There is no medium - it's either silent or "hairdryer in the background" high. Also, the app is sufficiently advanced/convenient that you would expect it to understand when the water level is too low for the pump to work, but it does not. When the water level falls below the pump depth, it just runs on high indefinitely as the humidity falls, until you get annoyed at the noise and wonder "why is my humidifier not humidifying properly?" Overall, 4.5 out of 5 stars. But adding a "medium" fan setting and water-level sensitivity could make this a truly 5-out-of-5 star device.
