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.

TL;DR I am very happy so far with my 6000s -- This is my third Levoit product, and I've always been impressed with their engineering and design. While the 6000s works WELL, it feels like it's missing a few details that would make it outstanding and thoroughly satisfying to use. I'm using this unit in my bedroom. I've been using the unit for about a month, in the winter (so the heat's been on and the ambient humidity has been low). First, the good: It does an excellent job humidifying the room quickly and keeping the room at a set humidity. I've verified this with an external hygrometer. This is what you buy a humidifier for, so... win! The water reservoir is ENORMOUS, which is a good thing. It has an unusual (but pleasant) method to fill the water: You take the top of the humidifier off (the part with all the electronics), wheel the humidifier base near to your sink, and you connect a plastic hose (with an extremely effective universal connector at the faucet end) to your faucet and place the other end of the tube into the humidifier. Filling takes a few minutes. Then you wheel the humidifier base back into position, put the top back on, and you're back to humidifying. Not lifting, no spilling... very effective and clever. So far, cleaning has also been super easy. I clean the humidifier every time I fill it. I dump out the small amount of remaining water from the base... rinse the base with hot water... and wipe it all out. I also wipe any other surfaces on the humidifier that look like they might need some attention. This has kept things nice and clean so far. Note that the instructions suggest cleaning every three days; I've been clearning at each fill-up, so more like once every week or 10 days, depending on the ambient humidity. Now, for the things that "need improvement": Auto mode is not at all useful. It adjusts the fan speed based on the room temperature and current humidify. Good, right? Well, not so much. It keeps the fan running at low (and thus the humidifier pumping out humidity) even after the target humidity level is reached. As a result, we had a night where we hit 60% humidity in the bedroom. So... that was the last time we used "auto" mode. The target humidity mode (where the fan comes on when the humidity is below a level that you set) works better... but this also requires that you pre-set a fan speed. So, whether you're 20% below your target or 5% below your target, it runs that humidifier at that speed. Which is not the best possible idea. The current firmware also seems to have a bit of a glitch in that the fan shuts off and turns on repeated in short cycles. Which isn't great. I have three Levoit air filters... and one feature that they have, that I *really* miss on the 6000s is the LIGHT DETECTION feature. With this feature, the display on the device automatically turns off in low light conditions... which is awesome for a bedroom. I *really* wish the 6000s had this feature. In summary... I like this product, but with just a few changes it would be a GREAT product. Still... definitely recommended.

I ordered this as a replacement for a failing Honeywell humidifier in a room where we store wine. We live in high desert and the humidity is typically below 25% and often 10% or below. I settled on the Levoit 6000s after considering several units of similar size. Unpacking it, this seems like a well built and very well designed humidifier. The capacity should be more than up to the job of keeping our room "wine comfortable" long enough to account for any time we are away. I've only had this running for three days now, but a couple of things impress me. First, it is quiet as compared to the other humidifiers I have used. Noise is not really an issue in the room this is used, but the difference is noticeable. Second, the humidifier does an excellent job of keeping the humidity near what I have set, as measured by a separate sensor located on the other side of the room. According to that sensor, the Levoit 6000s maintains the humidity level and is very accurate. The faucet hose attachment that is included is a nice feature. Lugging water containers back and forth has always been a dreaded chore, and this will eliminate the need for that. I'm not generally a big fan of app-controlled features on appliances, but the app for this product is pretty good. The main thing I use it for is checking up on it, but it is easy enough and has not thrown any fits. It's a good feature. After this short of time, the unit also seems efficient. The water usage is less than the old Honeywell unit while maintaining the humidity level. I saw another reviewer say this humidifier is doing the work of two of his old units, and I think that is consistent with the efficiency I have seen so far. The Levoit 6000s is about twice the price of the other units I looked at, but thus far I think it exemplifies the old saying, "you get what you pay for." Assuming it holds up (and from the way it is built, I expect it will), this is the best portable humidifier I have owned.

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.

After a horrible experience with ultrasonic humidifiers leaving white dust all over the house (not to mention causing respiratory issues), I chose this steamer unit (https://www.amazon.com/gp/product/B0B7F8144F/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) which failed a week after going off warranty. Not to mention cleaning off all the lime scale every week was a hassle. Then I discovered Levoit now makes an evaporative humidifier, which I hear is the way to go if you truly want a "whole house" solution. We have an older home that has passive radiant heat so cannot attach a unit to a forced-air furnace. This appears to be the perfect solution. We own other Levoit products and they have proven to be high-quality and reliable. The fact their products come with a 2-year warranty proves their commitment to that reliability. This unit appears to be no exception. After having this for a few days, I can confirm that this unit does indeed humidify our entire house. It is capable of dumping the entire 6-gallon capacity into the air in 24 hours on the highest setting. The weather is cold and our interior humidity was down to around 20%. All our house plants were looking wilted despite being watered daily. Now? Humidity on the main floor where the unit is stays at 50%. The upstairs where our bedrooms are runs around 40 - 45%. The plants now look perky and pleased on I'm no longer waking up in the middle of the night with cotton-mouth. The only downside is that to maintain this humidity, our water bill is going to soar - but that's not the humidifiers fault. The thing I *really* like is how easy it is to fill, thanks for the faucet attachment, and how easy it is to clean. Soak the water tank in a vinegar solution for 30 minutes, and clean the filters (a brush designed to do this properly is included). Because this is an evaporative process, there isn't the amount of residue you need to clean common to other types of humidifiers. I highly recommend this 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'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 :-)

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!

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.
