DREO 6L Humidifiers for Bedroom, 60H Runtime, 28 dB Quiet, HM524, Blue

Some helpful hints I found have helped to keep this humidifier working. First, make sure the tape and Styrofoam block are removed from the product. Second, when filling the tank, make sure that room temp water is added, especially the for the first time. Hot water may damage the seal. Third, do not fill water above the MAX level. The extra weight may cause leaks in the seal. Fourth, all small humidifiers like this will get bacteria/mold if not cleaned every 2-3 days. It is the nature of having water heating up for days without cleaning. If you don't like cleaning it every three days, understand that there will be mold/bacteria inside the base's small tank. It's just that simple. Cleaning is easy, but it takes some time to thoroughly clean the unit. ... and fifth, make sure NO water gets in the part that looks like a tower on the base's smaller tank. A small amount will flood the air intake and the electronics' board. This will mess up the controls. If it does happen, use a blow dryer on low to try and dry the board at the base of the unit. Otherwise, a couple of days should dry it out. If it isn't severely flooded, it may still work. Also, NEVER put anything but water in the tank when in use. Vicks, scented oils, or anything else will wreck this humidifier. The only thing I use in the tank is white vinegar to clean and descale it, but after that kind of cleaning, I rinse it out thoroughly and then dry it completely. Keep in mind, tap water is not the best water to use (lots of minerals) which is why white dust from this humidifier can go everywhere in the home and stick to the inside areas of the humidifier. Best to use distilled water or at least buy a demineralizing cartridge if using tap water (they last 4-6 months). Hope these helpful hint work for your humidifier. Took a lot of trial and error beforehand, but once I used this information, there hasn't been an issue yet with my Dreo humidifier or any of my previous humidifiers. Best of luck UPDATE: I started to have some issues with dust just like what others have be experiencing. I contacted Dreo by email and customer rep, Carol Hesung, was able to help resolve the problem. While suggesting that distilled water is the best way to combat the dust, I mentioned it wouldn't work out for me due to the high cost of distilled water per month. Carol understood and offered a complete refund for this unit and for the larger unit I purchased. Not only that, the demineralizing cartridge filter (3-pack) I bought was also refunded. Carol said there was no need to return any of these products. Not only was I pleasantly surprised with this outcome, it proved to me that Dreo is all about making it right for the customer if problems arise. With the actions Dreo has made, I will definitely recommend them and make future purchases from this company. Their customer service has been stellar and I wish other businesses would follow their lead. The Dreo team puts customers first and that is one of their best services offered. Thank you Dreo and thank you Carol. I was able to set the Dreo up quickly and finally get some moister back into my room. So far, this is product is working very well. It is super quiet, compact and easy to take apart, clean and put back together. There are many easily operated controls for such a small unit. 4L is quite small for my living room, but for a small bedroom, this will do the trick. I am pleased with the looks, the style, the easy operation, the light system, but most of all the steam output and the way you can direct the steam is an added bonus. If this can last as long as my old humidifier of 9 years, then I will be that loyal customer only to Dreo for sure. It really is a good humidifier even for its smaller footprint. Definitely recommend.

Update 4/17/2026: This is a great unit, I highly recommend cleaning the entire unit weekly to at most every 2 weeks. As my lung infection started to clear up, it started to get worse again! My doctor asked if I cleaned the humidifier yet? I said, "No, not yet". I can't remember the exact phrase she used, "humidifier bacterial infection". I cleaned out the the humidifier and was surprised with the amount of fungal growth that was in the very bottom of the both humidifiers especially the larger unit, this one! It took me a long time to thoroughly clean it out! one week later it had fungus growth but not much and was so much easier and quicker to clean out. Use white vinegar soft cloth and soft brush to clean out the base. By the way don't get water into the electrical part of the filter. If water does get into this section do not turn on until it is completely dried out or you will kill the unit! Updated: 2/8/2026 Dreo humidifier has been working non stop since I purchased it. My room has not got up to 60% humidity yet, the highest it got was 50%. However it doesn't hold it there long. I does go back down to 20-25% especially at night. I am feeling better but not fully healed... so, I am going to buy another one to help get the humidity of my room up to a healthy level! original post: Just what I needed for my small room, a new room temperature and humidity monitor I discovered my room humidity was 20% and for several years I kept getting sick at the same time of year, now I know why! This unit took 24 hours to get my room Humidity up 45% that is how dry it was, I feel much better already! The unit is whisper quiet and you can see the cool mist blowing up and the cool blue LED light is nice. I had to fill the unit up 3 times so far, I did not wait until the until shut down from the lack of water. I highly recommend this unit, well worth the cost. Less expensive than a doctor's visit for Upper respiratory infection and all the complications from that!!!

I really like this humidifier a lot! First off it's really easy to fill and use. It doesn't have one of those screw on caps, the top just comes off, you fill it, and put it in the basin and turn it on. Second it puts out a steady stream, it's effective. Third I think for what you get the price is great. It also has some other cool features that I don't care about as much but they're nice. It has a digital display that tracks the humidity in the room and you can set it to auto hit a target level. It's almost silent. It has a little night light feature that easily turns on and off. The digital controls are nice and easy to use. 5 stars, happy customer!

I have a house whose AC is good at what it does, but it also drys out my house very easily. I bought this in my computer room (where I am usually am) to moisturize the room as it is terribly dry. This humidifier is a cool mist humidifier. The mist comes out of a spout in the top, the water tank sits on the top of the base and the magic happens in the base as there's a cutout down there where the water gets evaporated, and the mist get sent up through tube in the middle of the device (up through the middle of the tank to the spout at the top). There is also a small plastic filter within the tank itself that is easy to remove clean and re-attach. The device itself is easy to fill and maintain (I empty the tank daily and clean it every two weeks). The device itself specifies you use distilled water, and I recommend you do so. It makes cleaning the device easier, and you don't need to clean the device as often. If you use tap water, all the imperfections in the water cause white residue and minerals to build up in the device (including bacteria and mold build-up). I would also recommend you get a hydrometer for the room you intend to use this in as I am not sure the way this device measures the humidity is entirely accurate (it shows it as a percentage on the front of the device). I use the reading to see how effecting the device is being (more or less). This also is not a "smart" device so you can't operate it remotely with an app on your phone. The machine also has an auto mode where you can set it like a thermostat, and it'll run the mist (lighter or harder or off altogether) dependent on how much humidity the device senses. If you don't prefer this, you can see the device between 3 settings low, medium, high (1 2 and 3 respectively); it will run the device at those strengths continuously. This device is fairly okay with water consumption. It will go several hours before you might need to refill it dependent on how much and what settings you run it. I recommend keeping a couple of bottles of distilled water on hand. Lastly, the device has a sleep mode and power button (which are on the same side). The "sleep" button will just turn off the interface while the vapor comes out (useful for when you sleep with the device). When cleaning, follow the manual's instructions. DO NOT RUN WATER ALL OVER THE BASE as there's some electronics in the base. When you clean the tank, be careful as the bottom of the tank will be a bit wet; only fill the tank when it's on the base otherwise you'll dribble water everywhere on your counter and such. I like this device and it works well. Just make sure you use distilled water (or invest in a countertop water distiller).

Updated 2026* It's perfect worth every penny don't look at any others because none of them have this kind of quality the mist goes 4 ft in the air the size was perfect for what I needed the functionality is very reliable up-to-date please read your brochure there are certain things that you have to do with this one but it isn't the chores of the old ones that I bought off Amazon many years ago and all they would do with just hold mold which I have lung disease that was the last thing I needed but that was in the old home we have moved years ago into a new home and unlike my old home this one's kind of dry so in my sleeping quarters I use it during the day when I'm awake and at night I have to turn it off because I sleep with fans and sound machines due to that annoying ringing of the ears and silence might be golden but it's also suffrage... As for me for $7.99 I bought off Amazon and asurion warranty plus if you look at the brochure and you call or contact Dreo go online and set up an account you can register your product now even though I just bought this and the asurion warranty is good.... but if you call the company they will extend it for surprisingly x amount of time I do not have to worry about this until 2028 so if you really want to ensure repairs if something ever happened I got double coverage it's very quiet I also have skin disease so when I lay across the other end of my bed the mist is so cool on my wretched skin it's very soothing and it actually kind of cools the room down a little bit as big as it is I can't say enough... The company's customer service I spoke to James who said I could use his first name from dreo...was very helpful as some of us baby boomers struggle with smartphones LOL I was having issues trying to set up an account and all that online business that you have to fool with and for some reason I missed a step and I was doing it wrong and he was kind enough to stay on the phone with me and walk me through it... While there are so many on here that look the same this is the best one and I'm only on day three I'll update if things get squirrely but so far so good and I don't see a problem this is unlike any humidifier... I've ever had and I'm old I had the old Vicks vapor rub ones which I can't stand the smell of vicks.... thank goodness also this device comes with a little pop out drawer in the back and they send you two little thick filters if you wanted to use essential oils... In my opinion and my choice I'm not going to be using that option because I don't want to have to have a smell in my room I like clean air I mean every now and then I use a shot of febreze... I can't say enough about this product and the ideal customer service is top shelf impeccable quality while there are many that look like this one this is the one you need to get and yes it was $60... then I spent another $7.99 for the asurion warranty so this is now becoming investment and it's double insured try it I promise you you'll never use another one this is the one I mean the runtime the longevity of leaving it on whereas my old one I was constantly refilling and degunking it and getting mold out of it was such a chore that I finally had enough of... My husband updated me with this and I am very pleased with it and I highly recommend it!!! 2026 UPDATE while all I said is still good here's what I've been dealing with even buying a lakes of the proper water or thru my filtration system of our water it still does this I now have to clean it every 2days & at my age is an arduous chore even with the dreo filters I jus think there's no such self cleaning or gunk breeding humidifiers still pleased with it but it's a chore I run it 16 hours a day I only cut it off at night time cuz I like sleeping with a fan on its still a good product but come on this thing is huge & you have to be careful with the bottom as it's corded & the face has the function power button on the front it's fickle my opinion is from experience no shade jus be prepared to clean it every other day 2 days if I'm lucky!

I've tried a lot of humidifier's, but this one is definitely my favorite and it's easy to take apart and clean. It runs quietly and holds a good bit of water so this will 100% last through the night. You can also turn on the light for a night light if you'd like which is good if you have kids or anyone who doesn't like the dark. I've had this for a little over a year now and have had no issues at all.

I absolutely love this humidifier! The large 6-liter tank only needs to be filled about once a day, which is much more convenient than constantly refilling smaller units. My favorite feature is the top-fill design; you can pour water in without removing the tank from the base. It's also incredibly quiet. Most of the time, I forget it's even running until I notice the cool mist. I liked it so much that I’m definitely going to buy another one! I accidentally knocked it off the table and cracked the tank (completely my fault! 😂). I didn’t even have to shop around for a replacement! I already have the 36-hour runtime model sitting in my cart, waiting to be ordered. That probably says everything about how happy I am with this humidifier.

The humidifier meets my needs, so I am happy with it. I purchased this one because I had a positive experience with the smaller Dreo 4L (model HM311S) that I bought a few weeks earlier. I should note here that my only prior experience with humidifier's was with basic on/off models of yesteryear. And that was what I was looking for when I purchased the first Dreo. The Dreo just happened to be on sale at a price equivalent to older type device, so it made sense to me to try it. I am glad I did. There are a few things about these humidifiers that you would not necessarily think you need until you have them. First, they are quiet. Very quiet. Second, you can control how much humidity they produce. Third, they have a night light - which is kind of helpful as you get used to where you placed them. The light does change colors normally, but I think you can control that. It's a gradual change and the colors all seem to have similar luminance. Fourth, the footprint is smaller which gives you a lot of options for placement Fifth, you can direct the flow forward or back by tilting the plastic output piece. Sixth, they stop running when the water is empty. And when you refill the water, it keeps the settings you had. Both models display the percentage humidity in the room. I think the 4L HM311S model works better than the 6L model HM524 because its reading tends to more gradually change. This might be a function of the room and placement. I am not sure that the sensor can measure the humidity much further than the device - I got the impression that the sensor might be picking up the humidity the device is producing at times (probably because of changing currents due to the A/C running). The pad on the 4L HM311S model seems more intuitive than the one on the 6L model HM524. Though I had no trouble getting either set up for my needs. Both come with some pieces for maintenance that do not attach to the devices. There is some risk that one might lose them or forget about them. One thing to note about these newer humidifiers is that manufacturer suggests using distilled water. Distilled water is relatively cheap as far as purchased water goes, but it is getting harder to find. And if you need to run these a lot, it can be kind of expensive. I ended up using filtered water from my fridge and just clean them more often. It is very possible my choice may lead to an earlier demise, but I reasoned out that it would like cost me way more in distilled water then the device itself. The 6L model HM524 seems to go through water faster when it gets toward the end of its tank. Again, could be the room. These are kind of tall and narrow. I did have a concern that my cats could potentially knock them over. It has not happened. The water adds a fair amount of weight to these so that probably helps. I doubt it would help if they engaged in rambunctious play and slammed into it. Larger animals and small children could certainly be a risk. The room size ratings Dreo provides are likely accurate, but there are a lot of factors that can influence that. It does make sense to have a larger capacity device for a larger area. Overall, I am very pleased with these devices.

Sehr leise und einfach zu bedienen Ich bin mit dem Dreo Luftbefeuchter sehr zufrieden. Besonders praktisch ist der große 3-Liter-Tank, der lange läuft und dank der Top-Fill-Funktion unkompliziert nachgefüllt werden kann. Das Gerät arbeitet angenehm leise und eignet sich dadurch sehr gut für das Schlafzimmer. Der integrierte Feuchtigkeitssensor ist ebenfalls eine tolle Funktion, da man die Luftfeuchtigkeit besser im Blick behalten kann. Auch das dezente Nachtlicht gefällt mir und sorgt für eine angenehme Atmosphäre. Insgesamt ein hochwertiger und durchdachter Luftbefeuchter, der einfach zu bedienen ist und zuverlässig funktioniert. Klare Kaufempfehlung!

Stille luchtbevochtiger, fijn voor de slaapkamer omdat het licht uitgezet kan worden.

We experience large swings in humidity over the year and it has become necessary to add moisture in the winter as the humidity levels have dropped to 10-15%. The DREO unit has been running about a week. It is quiet and has been very effective. Humidity levels have increased over a roughly 2000 sq ft area to between 30 and 45%. The DREO humidifier runs for roughly 24-hours on the 6L tank. We are filling it every day. I suspect that we will add a second humidifier next winter.

Super efficace et puissant…

Excellent indoor humidifier
