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.

These are simply the best humidifiers you can get for humidifying larger rooms with no white dust or needing distilled water! Unmatched capacity, easy to fill and clean. We use demineralization cartridges and silver ion cleaning fish/pods also, but its not mandatory. The filters will accumulate hard water deposits faster though and become less efficient. 3rd party filters work fine. DO NOT FILL WITH HOT WATER. This will ruin the pumps.

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.

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.

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.

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.

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.

First, you should know that I have something of a humidifier fetish!! I have purchase about 8 different humidifiers over the years and almost all have disappointed in one way or another. The only two that have impressed me have been the Vornado and this one. The problem with most of them has been with the wick drying out or developing a mineral crust through repeated use. This eventually prevents the wick from drawing up water from the base. Typically, this has meant replacing the wick filters mutiple times a season which can become an expensive proposition. I purchase a 6000S last winter and was impressed at how well it humidified and managed to keep the wick filters moist due to the way it pumps water into a channel on top of the filters and allows gravity to seep into the filters. When combined with a bacteriostat that prevents mold buildup, I am able to go for an entire season without have to clean it out. There are a few downsides to this humidifier and/or its VeSync app. First, the built-in humidistat accuracy is questionable. I have a separate Govee humidistat (which is supposed to be very accurate) and, depending on the location relative to one another, the 6000S can be off by several percentage points. Second, it's almost impossible to wheel the humidifier to a faucet to fill it up. When even half full, it is way to heavy to move easily over carpeting. I have resorted to using a 5 gallon bucket with a funnel to fill it up in place. Third, there is problem with the VeSync app and creating some schedules. Basically, the app is unable to retain a schedule that involves setting the humidifier to the "Humidity>Fan" mode. It always defaults back to the "Humidity>Smart" mode. I have alerted Levoit technical support to this problem and they've acknowledged it and their technical team is working on a revision to the app or they'll be pushing out a firmware update for the 6000S. Until then, you can only manually set the "Humidifity>Fan" mode setting. Finally, no way is this a whole house humidifier. We have a fairly small house (approximately 2000 sqft) and it is able to humidify one floor only. I had to purchase a second one for downstairs. All told, the 6000S is an impressive humidifier and seems better than most I have tried over the year.
