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

This is a review after having for 2 weeks. Background about me: I looked around at many different options for home humidification. Where I live in the North East, summers are usually hot and humid and fall and winter tends to be very dry. We had a particularly dry spell at the end of October, which lead to sinus issues and I needed some relief. I thought of getting a professionally installed humidifier for my central air system, but decided against that as running a water line to the attic which would be prone to freezing was not acceptable. I also looked at portable steam humidifiers but the choices were limited and not great. So, an evaporative humidifier it is. I have a large space; room-sized humidifiers don't do anything because of forced air heat (I have a venta airwasher which I am going to retire), so I needed something with a lot more oomph. I've tried ultrasonic misters in the past, and they are novel, but generally don't do a good job. The Levoit 6000s fits what I wanted. A humidifier that can work for my whole house (~2000ft²) and doesn't need constant filling and attending. In this super low humidity time of the year, 6 gallons lasts maybe 36 hours. The machine actually evaporates that much water, it is pleasantly surprising. RH increases rapidly up until about 45%, then it is slower as it diffuses. Seems to cease increasing the humidity once RH is about 60% and the temp is around 70F. Which is fine, 50% RH makes your nose happy and doesn't make everything feel damp. A steam humidifier might over humidify an area. The unit stops operating with about 1/2gal left in the tank. The water at this point turns yellowish, due to calcium being left behind. I also notice when the water level starts getting very low, and the humidity is somewhat high, you'll hear a slight tricking sound as the water from the pump isn't evaporating on the pads and is dripping back into the tank. Its not obnoxious though. Automatically shuts off when the water level is too low to continue. Has 3 fan speeds. I leave it on 2 as it just disappears into background noise. Speed 3 is a bit loud, I measured around 41db from 1m away. Speed 2 is below 30db, my meter won't read it. You can also turn off the lights, so if you are a light sleeper this won't bug you. Power usage on fan speed 1 is 3 watts, speed 2 is 8 watts, speed 3 is 21 watts. The bottom line is, this works great for your whole house, even with forced air HVAC, it has a lot of nice creature features you'll appreciate, and doesn't seem to need a lot of attention. It brings the humidity to around 50% quickly, but don't expect it to bring the humidity much above that on speed 2. Generally, that's the sweet spot for happy nose and skin anyway. The design is resistant to leaks and spills. If you can lift it in and out of your sink or bathtub go for it, otherwise it comes with a silly hose thing to fill it. Update: a few months later. This thing still rocks. I added a screenshot of an independent analysis of how fast this can throw the humidity out there. I replaced the pads with blue ones, and it's working just fine. Keep up with the mold and mildew growth, otherwise it starts to smell and can give you allergies. Run the unit dry and let it sit empty and dry for a few days every now and then. I bleach the pads and just dump a little bit of bleach in the unit every so often (like a couple tablespoons). It makes everything smell (like bleach) for a while, but it does the trick with sanitizing everything in the machine. Suggest doing the bleach treatment in a garage or other space where you won't be breathing it.

6 months update: I have had this for 6 months now and still very pleased with it. Added below a few things that worth mentioning: 1. No issues with the pump. Works just fine. 2. The water dripping noise is indeed something that happens, especially when the water level drops below half way. Doesn’t happen all the time but it does happen. If you have it in your room and you’re a light sleeper, it can be annoying. The way I fix this is by refilling the tank all the way up. I’ll try to experiment with other solutions and report back. A tip regarding reusing the wicks/filters - Every 2-3 months, they get a good amount of salt/calcium deposits on them, as expected. I have been able to reuse them by putting them in a descaler solution for an hour or so to break the salts, and then I wash them thoroughly. They look like brand new! Overall still very happy with it. Would recommend. 2 month update: Without the AC running in the house, the humidity is consistently higher compared to when we had to have the AC on. What has worked better for me is keeping the humidifier on low speed 24/7. It keeps the living room/dining room humidity between 55-62% and only have to refill the tank once every 3 days. Also, the pump is less noisy while on low speed. I think during the summer, with the AC on, having a more consistent humidity will be more difficult so keeping it on low 24/7 might not work then and I’ll probably switch to the auto function. Original review: No one paid me to write this review. I bought this to increase the humidity in our 1700sq ft house. And it did exactly that. It has a huge tank that can last you more than 2 days if you use the Auto Shut off function. If you keep the fan on high, it usually lasts slightly over a day. I’ve used it non-stop for 3 weeks now and there are my comments: Pros -Huge tank, easy to fill using the adaptable hose that comes with it (attaches pretty much to any faucet) -Brings the humidity up to 50-55% quickly and maintains it there without issues. -Even at high speed, the fan is not that loud. You can hear it but it’s not really bothersome to me (kinda like white noise). At low speed you can’t really hear it and at medium speed is barely noticeable. -Very easy to clean and maintain -Has wheels at the bottom so you move it from one room to another pretty easily -You can use wifi to turn on/off, adjust the humidity while away from the house -If it runs low on water, it automatically runs until the filters/wicks dry out so that they don’t get moldy -I haven’t noticed any filter discoloration or anything like that. The filters do eventually have salts on them, which is to be expected if you’re using tap water that is not that soft. Having said that, the machine comes with a small brush that helps clean those off. -The lights can turn off completely. Cons -The price point can be prohibitive for some people. It goes on sale sometimes for $200 (from $250). -Every now and then, the pump turns on to bring water from the tank up to the filters. That can be a bit noisy but it lasts for less than 10 seconds. If you’re sleeping at night and you have this in your room, turn the auto shut off function on (or sleep mode if you want). This machine can easily keep the humidity in a room 60-65% (maybe even more) without needing to run very often, thus decreasing any type of noise considerably. I will update this review after a few more weeks of use.

I genuinely think this is the worst appliance purchase I’ve made in years. This humidifier has turned into a full-time headache instead of something that’s supposed to help me sleep. The biggest issue is the filter design. The machine clearly isn’t properly designed for the filter it uses. Even with the “filter drying” function, it still builds up scale and disgusting residue constantly. Inside the water tank, slime starts forming no matter how carefully it’s maintained. It feels unhygienic and badly engineered. The humidity performance is also terrible. You can set it to 70% or even higher, and it simply never reaches the target. It just sits around 50% forever. The unit is not broken — this is apparently just how it performs. Refilling it is another nightmare. You can’t conveniently pour water in from the sink like a normal humidifier. You practically need a hose to refill the thing. Who designed this? And the noise… absolutely unbearable. When the water level gets low, there’s no warning or notification at all. Instead, it suddenly starts making loud train-engine humming noises in the middle of the night. Before that, it makes constant dripping sounds like water torture. I literally recorded videos because I couldn’t believe how bad it was. Imagine finally falling asleep and then waking up to either loud humming or random dripping noises because the machine gives you zero indication that the water is running out. It completely defeats the purpose of owning a humidifier. This product feels unfinished and poorly thought out. I honestly cannot understand how this was approved for sale or how people tolerate using it daily. Owning it has been a constant source of frustration, cleaning, noise, maintenance, and stress. My dream at this point is simply to get my money back and never see this humidifier again.

First off, ours had a problem. After about 2 weeks of use it started to squeal. I contacted support, they asked for a video to diagnose the problem, then offered to replace our unit at no charge and with free shipping. The replacement took a bit over a week to arrive. All products will have defects, what matters to me is how the company responds and Levoit gets an A+ from me here. What you should know: - You're going to want 2 of these to meaningfully cover 3000sqft through the winter... running on HIGH through the day and at least on medium through the night. - The low setting is very quiet and can easily keep a single large room comfortable, maybe up to 300+ sqft. - Because of how water is pumped up to the wicks, of course any extra needs a way back into the tank. If you have a quiet room you're probably going to find the resulting dripping very annoying. With creative use of some kitchen twine you can give that water a route back to the tank that doesn't involve falling. I'd love to see Levoit solve this problem in future models. - The included cleaning brush is designed to perfectly match the wick's fin spacing making adequately cleaning the wicks possible and we've gotten a full winters use out of the wicks that came with the unit(s). - Use a bacteriostatic to keep the biofilm buildup from happening. I didn't for the first half of the winter and had a long afternoon of using StarSan cleaning out the biofilm. I'm a homebrewer so I had StarSan on hand - baby bottle sanitizer would also do the job if you have little ones - or of course I'm sure there are other humidifier cleaners that work too - I'd avoid something like bleach. This cleanup made me appreciate the high quality silicone tubing used, it was full of gunk and after killing it, that gunk came right out with the pressure from my sink faucet spray jet. What I found: As we had an "extra" humidifier that we didn't want to use as-is, one of my boys and I did a teardown on it to see if we could salvage it. The engineering, material choices, and design considerations were impressive. - All screws were ACTUALLY stainless steel, not nickel plated junk. And there were quite a few screws. - The circuit board was conformally coated to protect it from moisture. This is very important for longevity of a product like this. - All connectors were siliconed in to ensure they don't work loose. - As we took it apart the robustness of the design and the quality of the design for manufacturing made it obvious that whatever team designed this product knew how to do it and that this product probably went through considerable revisions to reach its current level of refinement. - The fan assembly involved (probably) ABS blades very well glued over a large diameter machined aluminum slug (maybe 1.5inch dia) which then slid over the motor shaft. We were not able to non-destructively remove this assembly, so we didn't. This construction allows for much more precise, and longer lasting, mounting than if the whole assembly was plastic being pushed right onto the small diameter motor shaft as is typical on the market. What was wrong with our unit: The fan assembly was pressed too far onto the motor shaft leaving insufficient clearance and the fan assembly was just barely rubbing on the chassis. Despite considerable efforts I could find no way to non-destructively remove or loosen that assembly, believe me I tried. Short term fix: My first "fix" for this was to sharply strike the top of the motor armature with a 2oz hammer, this "fixed" it for a couple of weeks - more than long enough for the replacement unit to arrive. Unfortunately it started squealing again and repeated strikes stopped doing the trick. Fix that's holding so far (2+mo): A little silicone lubricant (DeoxIT X10S) applied to where the fan assembly could rub the chassis. As the cold season is winding down I've finally put it back together. I clipped off the fan guard so I can get in there to lube it again if needed next year. And yes, I really could leave it disassembled and still use it because of the excellent design choices made - basically the outer cover is optional if you try hard enough to get it off ;) There's an inner frame that can be used alone to support the fan unit.

*UPDATE: I am lowering the stars from 5 to 4 Here are the two primary reasons why: 1. I need a handle or something to grab on the lower reservoir Sometimes, I want to fill the tank fast, so I use my bathtub to do so. However, it is really, really hard for me to lift the full water tank from the bathtub and put it on the floor, as the plastic material of the tank has nothing for me to grab onto. I know we have an easier way of filling the tank using the tube, but I have overfilled and flooded my bedroom twice as I was not paying attention. It is painful to clean the water in your carpet, so please ALWAYS pay attention when filling using the tube provided. Flooding my bedroom is my mistake; I do not blame the humidifier. 2. Water Dripping Sound at Night: I have roommates, so putting the humidifier in my bedroom is my only option. The fan is quiet at night and won’t disturb you from sleeping, which is good. However, even when I put the humidifier in night mode, I can hear water dripping from the top compartment to the lower water tank, which sounds loud at night. I can’t sleep with the sound of water dripping, especially when the water level is low; the sound is obvious to me. It should be fine if you put the humidifier in another room. I investigated and found huge water beads on the plastic panel attached to the upper compartment, which drips down to the tank. If you mind a water dripping sound or can’t go to sleep with any noise, don't put it in your bedroom or consider alternative options. However, the humidifier still performs well and is efficient. Functionally, it is worth a FIVE star, but with the two issues I mentioned, I think it still requires some improvements. *Initial Review Living in the dry Midwest, I replaced my old Levoit ultrasonic humidifier after discovering mold and learning about potential lung hazards from water particles. This led me to explore safer options. I was only considering Levoit or a German brand, as other brands are ugly-looking, in my opinion. I settled on the Levoit Superior 6000S, their first evaporative humidifier. Not only was it more affordable than its German counterpart (priced at $249 versus $500+), but my positive experience with Levoit's air purifier also influenced my decision. *First Impressions: Stylish Exterior, Underwhelming Interior The humidifier boasts a sleek, modern design that fits well in any room. However, the internal components, particularly the fan, feel cheap. They remind me of something you'd find at a budget store. *Setup and Operation: Simple Yet Effective The setup is straightforward. The system pumps water from a reservoir to the top, trickling down through filters. As air passes through these moist filters, it picks up moisture and is expelled, humidifying the room. The process is essentially middle school physics, but it's impressively efficient. *Performance: Exceeds Expectations I heard that evaporative humidifiers require longer to improve humidity than ultrasonic ones. I tested it in my 500 sqft apartment (though it's rated for 3000 sqft) and was amazed. The humidifier increased humidity from 27% to 50% in under two hours, even with a window open. At its lowest setting, it's pretty enough. Even if I put it 5 feet from my bed, I can still go to sleep, and it maintains the humidity at 50% at its lowest fan speed easily. (Note: with my bedroom door closed. My bedroom is probably around 300 sqft.) *Areas for Improvement *Water Refilling: The included plastic tube works well with tall faucets but struggles with standard bathroom sinks, leading to bending and restricted water flow. *Maintenance and Cleaning: The long, curved water tube connecting the reservoir and the top part could pose cleaning challenges similar to those encountered with a fish tank. However, the unit's design minimizes hard-to-clean corners and edges, making it generally easier to maintain than traditional humidifiers. I plan to use a bleach-infused cleaner for effective cleaning and disinfection. *Final Thoughts on the Levoit Superior S6000 After giving this humidifier a whirl for a day, I'm happy with it. It does what it's supposed to do without any fuss, and it gets my thumbs up. But I won't lie – the build and the primary mechanism make me question the price tag. Is it worth what I paid? I'm on the fence about that. Stay tuned, in any case. If anything significant pops up, good or bad, in how this thing works or what it's like keeping it clean, I'll be sure to drop an update. For now, if you're in the market for a no-nonsense humidifier, the Levoit S6000 is a decent pick.

I have had almost every humidifier type made. This one is heads and tails the best one. Easy to fill, 6 gallons last at least 24 hours on the coldest, driest winter days, nice and quiet, easy to clean. I have it on our main level and just run the furnace fan about 20-30 min / hour and it does all 3 levels, about 1900sq ft. Took our humidity from upper 20s to mid 50s in about a day. I just packed it back up for summer. Another plus is that since my water is not too bad (about 110 PPM TDS) the filters lasted all winter. Also aftermarket ones are available to keep costs down.

This is one of the best humidifiers I have had that works to maintain a good humidity level of my 1600 sqft 3 bd spit ranch style home and I placed the humidifier in great room area of my home for best coverage. It has an easy-to-use app that connects through Wi-Fi and Its the quietest humidifier that I have ever had. The temp was off -2 degrees and humidistat was off about-10 degrees do to it senser placement and lock of air flow. You can by a cheep mini usb fan to place in front off the senser or put the humidifier near a heat vent where there's air movement. It is well built with the top outer shell being aluminum and the rest being plastic. Though filling and cleaning is not any easer then any of the other large humidifiers that I have owned. Unlike most humidifiers this has a water pump that works in the same way a swap cooler does by keeping the wicks wet when in use and then dries them before it turns off to extend their life. Most humidifiers do not have a water pump and rely on the wicks absorbing the water in the basin and to only to have haft the wick staying wet reducing its ability to humidify the air. The water pump prevents contaminates build up from calcium and hard water by continuously flushing the wicks with water allowing the wicks to last month’s not a week or two like most humidifiers without a water pump.

I purchased this humidifier in July 2025, in preparation for the 2025-2026 winter. It is now January 2026 and I've been using this unit since the temps dropped to the single digits and low double digits here in Michigan. I must say that I am impressed with this humidifier. We have a 1900 sq ft home and I set the unit in the living room. Within a matter of a couple of hours, the humidity in my home went from the mid-thirties to the mid-forties. I run the unit on the middle speed as it is more than enough to maintain the mid-forties humidity level. A couple of times, it even reached the set-point of 50% and shut down for a short time. The unit is fairly quiet when running on the middle speed. On the high speed, it's a little noisier but I've used it several times on high to raise the humidity quickly and for fast drying out the water pads. I fill the water reservoir to the max level and on the middle speed it lasts a little over twenty-four hours. When the water is used up, I configured the settings to automatically go into dry mode with the fan set to high. It runs in dry mode for 30 minutes and then powers off. We have a water softener in our home so the four water pads do not accumulate much sediment from the water. Once a week I follow the maintenance and cleaning instructions provided in the manual. I purchased some citric acid and mix it with water according to the instructions. I also soak the water pads for a couple minutes in the citric acid solution to remove any sediments. I also used an electrical wattage meter to see how much this unit will cost while running 24/7. The meter is showing approximately 8-9 watts on the middle speed. Using the meter's built-on cost calculation, it will cost around $1.30 per month. I highly recommend this unit. It's a little pricier than some of the competitors but I am glad I spent the extra for this brand and model.

I've been using this product (Levoit Evaporative Humidifier Superior6000S) for 10-days and I am impressed. It has helped considerably with my humidity problem and the smart feature is fantastic. It is quiet, it holds tons of water and it performs the way it is supposed to.

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 :-)

This humidifier does indeed humidify a large room quickly. However, my first humidifier started making a loud, piercing noise just a few months after purchase. I contacted customer service and received a replacement under warranty. After waiting two to three weeks in dry air, the new unit finally arrived. At first, it worked fine, but within less than a week, a part securing the fan fell off. That part is now stuck inside the fan, and I don’t think it’s safe to use the device anymore. We are currently in contact with customer service again, and I will post here for further updates

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!

It’s hard to find a large evaporative humidifier at a reasonable price. This one fit the bill and overall I’m very satisfied with it. The humidifier itself does its job perfectly, the companion app is convenient and works well, the digital display shows percentage of humidity readout (also available and changeable in the app), and I only have to refill about once a week. Every time I refill, I clean the humidifier. This is where the design flaw makes its appearance. Each of the four corners inside of the reservoir has a hump that is impossible to clean between hump and inner wall. I can’t even clean the orange gunk in the deepest valleys with a q-tip unfortunately. It’s too bad because it’s an otherwise excellent machine, but still worth the purchase for me. Lastly, the four wax filters it requires last a long time, but are not available to buy ANYWHERE in Canada. After contacting Amazon and then the company about finding these filters, I was told that they will be available in Canada in February 2024. It’s Feb 9 and they are not yet on Amazon, but I will be following up at the end of the month if I still can’t find them. I hope this review helps you out!
