Good quality, have had this for a couple years without any problems. We follow the instructions and clean it when it is time, and only use distilled water. Anyone that says it produces powder, must not be using distilled water. It's quiet, and works well at keeping the humidity right where we set it. No leaks, no problems. Great value for the money IMO. Oh, it's easy to refill

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.

Great when needed, love it this thing is a pain in the rear to deal with, changing water frequently, cleaning, finding the right products to use to stop white debris from collecting … wish I hadn’t waited past the return date! I rarely use it. Oh, steam comes blasting out white even on lowest setting. Not for me, but may work for someone who doesn’t mind all the care it needs!!! Also, not recommended for use around my pets and fish!

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.

Having gone through a variety of humidifiers, all in need of some kind of stand, the feature we like most is the "stand alone" one. The design lets us reclaim space. No more heavy, clumsy, stools, boxes, or make-shift props to get the mist off floor level. In the night, the remote, on your nightstand, makes operating extra convenient. Very easy to read the control panel at a distance. No need for a funnel or some other tool to keep water from spilling while filling. Lift the top off and you have a good sized opening to refill. Choose to keep the unit lit or dark while scaling the humidity up or down, with simple controls. A small, built-in option exists for Eucalyptus or other scented oil. Really a good output and have not seen any accumulation of any particles, stains of any kind. The mist it gives off is steady, with a sensor detection room humidity level. Maintenance on this is not demanding and we've had it running every night since it arrived in early winter. Advisable to know where your water falls on the soft to hard scale. Determine how much effort you need to prevent mineral deposits from forming. Our water is fairly soft and this has not been a problem Instructions for operation and a small cleaning brush, and remote control, are included. Again, what a bonus the remote control is!

I just purchased this humidifier for the cold winter in the northeast. Read the reviews, and it seemed like a good option. Set it up yesterday at 4 pm. Easy to set up, took less than 10 mins. Connected to the wifi/app and that works really well. Nice overall unit. Tall, holds a lot of water. Very quiet. Set the timer for 12 hours. Throughout those 12 hours, here is how it performed in our bedroom which is about 350 square feet. Note, I shut the doors and obviously the windows were closed (windows are new thermal windows) Starting humidity was 33%. It got up to 40% in about an hour, then dropped back down to 36%. Why? The heat was on, we have forced air and the dryness of the heat coming through the vents overpowered the humidifier. At night, especially in the very early hours (i.e. 2 am), the humidity level got up to 56%. We lower our internal heat at night to 65 degrees and recently got new windows throughout the house that keeps it there. Then when the timer shut it off at 4am, the humidity dropped down to 38% with the rest of the house at 34%. So, my conclusion is this is a good spot unit that can get your humidity up in the winter as long as it keeps running and you aren't blasting the heat in your home. Did I expect more? Yes, I did given the room it was in was half the size of its stated capacity. Also because of it's size I didn't expect it to be overwhelmed by the heat from the vents so easily. I also expected the higher humidity to stay signifcantly higher longer after it shut off. But, I still like it because I have never been able to get our bedroom in 50+% humidity in the winter and it did make a difference while sleeping, which is primarily what I was after. So tonight I'll run it 7pm to 7am to get the room at higher humidity further into the morning. Hope this helps.

I've had the unit form 5 months. Worked great at the beginning, easy to use, thin and very quiet. Calsificaction occurs in the motor part of the unit and then a part of the unit cracked where calsification built up. I attempted to decalsify, but then the unit would not turn on at all. I assume this is why it became inoperable, despite trying the recommendatins in the manual.

After trying several humidifiers over the years, the Dreo HM735S Smart Humidifier has easily become a favorite in our home. It's designed for larger spaces (up to 700 sq ft), and it truly delivers — you can feel the difference in air quality within just a few hours of use. The 11L water tank is a huge plus. I only need to refill it every few days, even with regular use. The top-fill design is extremely convenient — no spills, no awkward lifting, just open and pour. It’s very user-friendly. Noise is practically nonexistent. At just 26dB, it's whisper-quiet, making it perfect for bedrooms or a nursery. We use it in our baby’s room, and it never disturbs sleep. Plus, the auto mode does a great job maintaining the ideal humidity without needing to constantly adjust settings. The smart features are the icing on the cake. I love that I can control it through the Dreo app or the included remote. Adjusting mist levels or setting timers from bed or while holding the baby makes life so much easier. The self-cleaning tank feature also gives me peace of mind when it comes to hygiene and maintenance. A few thoughtful touches I really appreciate: The aroma box works beautifully for adding essential oils The RGB ambient light is subtle and calming, great for nighttime use The design is sleek and modern — it doesn’t feel bulky in the room If you need a powerful, low-maintenance, and truly smart humidifier for a larger space, the Dreo HM735S is worth every penny.
