This is the ultimate humidifier BUY IT but u still have to clean it
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!

Quiet and nice humidifier.
I accidentally ended up buying from an Amazon reseller account and received a damaged unit. Before returning it, I decided to contact the customer service of DREO to see if they could provide a quick fix or if they knew something I didn’t. To my surprise, they sent me a new unit. This was a pleasant surprise from the customer service. I received a new unit after a couple of weeks, and it works flawlessly. I love it. It’s quiet and can raise the humidity in my large bedroom within 15 minutes if the doors are closed. I love it for its ease of use, especially since I don’t have to remove the tank to refill it. It’s a top-loading model. Since Colorado is such a dry state, it has been very helpful, and my sleep quality has improved significantly because of it. It’s affordable, high-quality, and you get excellent customer service. What more could you ask for? Grab one as soon as possible.

Love this humidifier!
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.

A better 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.

Like They Used to Make Them
I purchased two of these for my kids' bedrooms. I don't have a single complaint (and I have strong opinions when it comes to humidifiers lol). Packaged nicely. Right out of the box, no crazy chemical smells like some new plastic products often have. Super easy to assemble and comes with a little cleaning brush. My favorite part about this humidifier is probably that the entire top comes off making it easy to fill. It's really easy to clean as well. The settings are easy enough to figure out. My second favorite thing is that the color of the light indicates if the current humidity level is low or optimal. It acts as a nice night light as well. The output is great at well! It works very quickly to raise the humidity of a bedroom if the door closed. I'm not sure how it would work in a larger room but for 200-500 sq ft, it works really well.

My favorite humidifier
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.

Great little dehumidifier
Small not big so far works great and pulls in moisture . I always keep it at L2 speed . Bought 5 of them to put in each bedroom and livingroom . Cleaning is very easy , quality is more than I expected, when the moisture fills the little tank will stop until emptied , does light up and not bright , great price . Highly recommend .
