UPDATE: I’m actually bumping this into 5 stars. The hygrometer is working much better and the humidifier is maintaining the room well right around 45%. It’s super quiet and lasts a long time with the large tank. As long as this thing keeps working as it should, I am very happy with it! UPDATE: After a couple more days of use, the hygrometer appears to be getting more accurate. It seems as if the abnormally high readings occur after filling the tank full, but this seems to improve as the unit is used. ORIGINAL REVIEW We just received this humidifier a couple days ago and so far it’s been working well. I’m using it in an upstairs room where I keep some guitars to keep the humidity controlled during the cold winter months. We have an integrated whole home humidifier hooked to our furnace, but prefer not to keep the whole house too humidified to reduce condensation buildup on the windows. This little unit does a nice job for a small to medium size room and the extra large capacity is really nice, only have to fill it every 2-3 days even running almost constantly. Having the app and WiFi capability is nice as I can remotely control it even when not at home. My biggest gripe is the hygrometer reading is WAY off compared to my other in-room hygrometer, which makes the Auto function almost useless. Readings are constantly 10-15% higher than actual, mainly because it seems like the unit’s hygrometer sits quite nearby where the mist is being expelled (it appears it’s probably on the back of the unit head, but even with the mist shooting away from it, readings are quite off). So if you’re looking for accuracy to use the Auto function, this may not be the best unit, but if you plan to keep the humidifier running constantly during the very dry winter months and prefer large capacity for minimal refills, this is a good unit to consider. I obviously can’t speak on the long term function of the unit, hopefully it holds up as I know a lot of these types tend to work for a year or two and then go kaput.

We have a fairly large living room, so we were looking for a bigger humidifier that wouldn’t need constant refilling. This one turned out to be exactly what we needed. On one full tank, it lasts us about 5–7 days, which is amazing. It humidifies the room really well, runs quietly, and doesn’t bother us at all, even when it’s on all day. I also really like how it looks very modern and clean, doesn’t feel bulky or cheap. The display is easy to read, and the water level is simple to check. Overall, it works great, looks stylish, and is perfect for larger spaces. Very happy with this purchase.

Fantastic humidifier. Puts out significant mist immediately and high capacity water chamber let's you avoid frequent refills. Very stylish as well

UPDATE: DO NOT PURCHASE I bought this in December, used it 2 weeks before I went to spend the holidays with my children. I started using it Jan 3rd, and today is Feb 3rd. Had to buy distilled water b/c Dreo STILL does not have any filters in stock, so in order to not have white powder on everything, Dreo told me to use distilled water. 3 months later, they STILL do not have the necessary filters!!!! It takes about 4 gal of water to fill properly. This morning, I filled it as usual, turned it back on and got a cup of coffee from the kitchen. I turned around and ALL the water I put in the device was leaking out of the bottom all over the floor. Thank God I didn't place it on my Persian rugs!!! I could NOT lift this device to empty in the sink. I blocked the area with heavy towels to absorb the water. When it got low enough, I could lift it and empty in the sink. All 5 huge towels were soaked with the water. It only took about 5 minutes for this as the water was leaking like a sieve. I called Dreo customer service to get help. To get a replacement, they sent me an email with a LIST instructions that I had to do, in order to GET a replacement. I'm 72 years old and in a wheelchair. You can imagine how DIFFICULT all this was for me to clean up. I don't know how to screen shot and email my receipt from Amazon. Couldn't just take a phone shot and text it to ANYONE. When I explained that I am not tech savvy, the kind customer service gentleman was understanding; but their "rules are rules". I explained I am in a wheelchair and cannot get this device to UPS for a return and I refuse to pay for pickup. I admit I was getting more and more aggravated. I asked him then to just refund my money and I would buy a new humidifier that I KNEW would not leak from another seller. I had a console humidifier for 25 years that had finally died. It NEVER leaked. I would rather have the large console than this sleek tower that leaked!!! AGAIN, I still had to do everything on their list according to their rules AND return it to UPS. I don't know about you but I am NOT going through this. As I read about this product on a Dreo site, these have a history of leaking AND support will give you directions to troubleshoot FIRST before replacing. This old broad is NOT doing this! This was an expensive device but not worth a penny. POOR CUSTOMER SERVICE Purchase at your own risk! December 12th: I love this humidifier. I did not realize that the demineralized filter did NOT come with my purchase as it was stated in description. I can't find anywhere to buy that filter. I even went on the DREO site and could not find. If you don't have the filter, you end up with white powder ALL OVER everything. My housekeeper constantly is wiping down cabinets, every black appliance in my kitchen, it even gets on the glass of my windows. It is a MESS. I do have a number for Dreo now so will call them tomorrow to order 12 filters (1 for each month). I'll let you know how they work. If this white powder continues to appear on EVERYTHING, I will toss this expensive product. I believe b/c of where I live it is salt that is what is getting on everything. I'm surprised as I have a filter on my kitchen faucet's cold water AND I filter that water in a water pitcher. So the water I am putting in my humidifier is doubly filterered.

Very happy with this humidifier (so far). The Dreo app is useful and easy to set up. It also works with Alexa, so I can just voice command it on and off, which is great! It can be scheduled too (no more forgetting to turn it off when I leave the room). It’s not getting the room up to ideal humidity levels (45-55%), but I don’t think I’ve ever seen a humidifier that really can do that, so I don’t expect it to. It’s making a noticeable difference anyway, getting my humidity levels to consistently hover about ten percent higher than they were before I started using it. It’s sleek and discreet. Even though it’s a larger unit, it takes up very little floor space. It has two vulnerabilities, as far as I can tell: 1) You can easily ruin it by pouring water into the wrong spot if you don’t read the instructions. So pay attention to that, and make sure everyone who might fill it, knows what to avoid. 2) It’s super stable on its feet, which makes it possible to knock over if you’re the type of person who might bump into things. I keep mine beside a large plant to give it some protection.

This unit works well and adds a good amount of humidity to a larger area. We have ours in the living room and it increased the humidity from 28% to 43% in a couple of days. We have it running at the highest speed and only have to fill it once per day. It has been a huge help with keeping the air comfortably breathable!

Really happy with this humidifier, it has been a cold winter and this humidifier keep some moisture in the air, I have one connected to the furnace but doesn’t do near the same job as this DREO! Easy to fill from the top and sit nicely in the corner of the family room and provides moisture to the entire floor It has a filter to prevent the white dust which I love! Love it so much I bought a smaller version for the bedrooms

I've been very pleased with most of the products I've ordered from DREO in the past, so I did have high expectations for this 11L Smart Humidifier when I ordered it. Overall, it has helped to raise the humidity in my house this past January while trying to battle winter dryness. I will say, don't expect miracles in a day, as it seemed to take the better part of a week to truly make a difference, at least in my home. My humidity rose from 30 to 40 in that time. My biggest piece of advice is not to set it on Auto, nor to let it run on the highest mist setting, as that is simply asking for considerable white dust to be dispersed throughout your home. Granted, I wasn't using distilled water and thought I could avoid that extra cost and/or time by having the DREO demineralization cartridge - but it did not. Sure enough, my hardwood and numerous household items end up with varying degrees of white mineral dust accumulation. So, I set it to the lowest mist setting and over the course of the next week, I noticed probably a 95%+ reduction in white dust. It also wasn't consuming water as fast, which logically made sense. Basically, depending on your HVAC system and air circulation, you'll need to find a balance. In the end, I'm happy with 40-42% humdity and little to no white dust; however, it would have been nice to utilize the auto settings. The 11L capacity is great, it's also easy to fill and clean as required. And it operates relatively quietly, at least on the low mist setting. Still a recommended buy, but with the caveats noted above.
