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

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.

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.

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 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!

I like the large capacity water basin. I run this in my basement where my wood stove is and I only have to fill the water once a day compared to my other one which was 5 times a day. Also not having to deal with chemicals is a big plus. I’m a little concerned about mold growing, but if I use the drying setting frequently, that should work? The computer in it isn't very smart. I set it to 45% and it will pump to 48%. And I’ll set the fan on level 3 and it will lower itself. I don’t use the wifi stuff because I don’t think it needs it.
