DREO 6L Humidifiers for Bedroom, 60H Runtime, 28 dB Quiet, HM524 | Precise Humidity Control, Easy to Refill & Clean, Nightlight, Cool Mist Humidifiers for Large Rooms, Baby Nurseries & Plants

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! Original post: This is an excellent cool mist humidifier. puts out small to large amount of mist and to can set it to automatic or manual mist amount. This perfect for small to large rooms. I have a smallish size bedroom packed to the gills so I purchased the DREO 3 liter model unit. The humidity level was 20% and I got very ill, lungs infection with congestion, sore throat and sinus congestion with eye ached and headaches, I was a mess! This was a yearly thing and thought it was seasonal allergies... This unit could not get my room above 40-45% running 24-7 for 8 days, I started to feel a little better. I ordered this unit and running both units together, it took 2 days to get it up to 65% where I have it set too. I am finally starting to feel recovery! I may need to turn up the humidity at night as my throat still gets dry. The humidifiers use more water at night too. I do have an electric heater which might be why the room gets so dry, this heater was designed not to dry out the airs as much as others, so they say! In conclusion, I would recommend the larger unit over the smaller, both looks and works great and are quiet too!

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!

This is a really nice humidifier. I've used a lot of humidifiers in the past and they usually do the job. This one meets the need and has a few surprise extras. The large canister was essential for my very large bedroom. I'm in San Diego where it's dry, and it took 2 full fills to bring my room to 65% humidity. Now that I'm there, the canister only needs filling once every few days. I love how much comes out at once. I've never seen that much on any humidifier I've had. And the nice surprise is being able to angle it in a direction so that it can come down directly onto my head while I sleep. This thing is silent. No noise at all. It just does it's thing without a hum. The controls are very easy. I set the desired humidity to 65% and it just goes. I love that I can see what the current humidity is from far away. The display is really clear. The light is nice and not terribly bright and I like that it can be turned off at bedtime without turning off the function of it. One of the really nice surprise is how easy it is to fill the canister. If you pick it up it comes easily out of the base. And unlike any other humidifier I've had, the canister sits flat on a counter so you can refill it without holding it. It also feels really sturdy. I think I'll probably by another few for my guest rooms as visitors tend not to be used to the dryness here. I highly recommend this product.

This humidifier has been a lifesaver during the winter months. It runs so quietly that I barely notice it’s on, even at night, which makes it perfect for the bedroom. The large tank really does last a long time, so I’m not constantly refilling it. The top-fill design is my favorite feature — it’s so convenient and mess-free compared to others I’ve used. Just pour and go, no awkward flipping or spills. Overall, it’s easy to use, very quiet, and keeps the air comfortable all night long. I would definitely recommend it for anyone looking for a low-maintenance, reliable 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.

When you set it to auto on a dry day, the tank will run itself dry in just 12 hours if used in a large room. It sounds bad at first but it means this humidifier can increase its mist output in response to dryness, so I am 100% satisified with that. It's nice and quiet and odorless. The size of the water tank is great and it does last 60 hours if humidity is 30-60%. The lights are great indicators of the humidity level: yellow if dry, green if just right, and blue if it's 60%+ humid. My one caveat is set the humidity setting to 60% if you want to put it on auto to account for the built-in hygrometer being closer to the mist than the rest of the room because this thing lowers its mist output as its hygrometer reaches the selected humidity level. I've had it for a year and no issues.

I did a lot of research before I decided on a humidifier and I’m very pleased with this one. I live in the midwest and have forced heat air and so it is very dry in my house during the winter. I’ve had this humidifier for over a month now and it works great. It’s attractive, not too large and I love the optional light. I’m using regular water from my faucet so I purchased the matching humidifier filter which I’ve changed once. I have not seen any mineral dust since I’ve been using this humidifier. When my heater is running a lot I need to fill it about once every 24 hours. When the outside temperature is in the teens to twenties, it’s able to get my humidity to about 30 to 35%. (Without the humidifier my humidity would be in the low to mid 20s) When the temperature is above freezing it easily gets my humidity to 40%. It might go higher than that but I have it set at 40%. My house is 2500 ft and I’m using this in a large bedroom. My daughter has the same humidifier and her house is 1200 ft. The humidifier has no problem keeping her entire house at 35% to 45% humidity even on very cold days. She was able to get it to 60% on an average cold day but that might have been a little too humid.

Easy to clean. I have several. I did notice a burn mark at the bottom of one of my units after 6 or so months of use. I didn’t hesitate to just replace it because it’s so easy to clean and seems to work so well. No leakage and no noise at all. I love the light but my husband can’t stand it so it’s usually turned off.

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.

Great for a bedroom. We fill it once a day. Love filling it from the top with a jug of water. Extremely quiet.

Excellent unit. Works like a charm even with my very hard water.

Super quiet, nice choice for flow. I did not realize you could use distilled water in it and had already ordered the demineralizing filters which are not required if you use distilled water. Happy with the product itself.

This is a really nice looking humidifier that doesn’t detract from a rooms aesthetics. It’s quiet and efficient and is also suitable for the bedroom if you don’t mind an almost indistinguishable hum. Although mostly made of plastic it seems well constructed and should last a long time. The cord is 5 feet long which is a pretty perfect length for most use cases. It’s especially nice that it includes a humidity sensor for effective control of your rooms humidity. The fact that the colour of the light reflects the humidity level is also a nice touch. However if you’re not into coloured lights in your house and switch it off, the display also turns off meaning you have no ability to see how it’s performing without turning them back on. These should be independent switches in my opinion. Also the buttons themselves are not illuminated making it difficult to know which one you are pressing especially if you’re not in a bright room. Having a top fill tank has its benefits, but it also means you have to have a spare jug lying around. And because this is 6L you’re going to have to make multiple trips, unless you refill it more frequently than it needs (which kinda defeats the purpose of getting a large capacity humidifier) In the instructions they do recommend using distilled water and descaling once a month which is all a bit of a pain and would’ve been nice to know before purchase.
