DREO 4L Humidifiers for Bedroom, 36H Runtime, 28 dB Quiet, HM311

Bought this for my sick 2 year old and I absolutely love it, it’s easy to use and super easy to clean (huge plus). It has multiple settings and even a night light that my kids love because it looks like a water lava lamp and the sound is peaceful and not obnoxiously loud.

I really love this humidifier! It puts out a steady, noticeable mist and helps the room feel much more comfortable, especially when the air is dry. The large water tank is one of my favorite features because I don’t have to constantly refill it, and it can run for a long time on a single fill. It’s also surprisingly quiet, so I can use it in the bedroom without it being distracting at night. The display is easy to read, the design looks sleek and modern, and the mist output is simple to adjust. Another feature I absolutely love is the reservoir for essential oils. I added an apple cinnamon essential oil blend, and it made the whole room smell warm, cozy, and just like fall. 🍎🍂 The fragrance gently fills the space while the humidifier runs, so I get the added moisture along with a beautiful seasonal scent. It’s easy to use, looks great in the room, and makes the space feel so much more comfortable and inviting. I would definitely recommend it for bedrooms, living spaces, or anywhere you want extra moisture with the bonus of a cozy fragrance.

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.

Before setting this out, the average humidity on any given day was around 52%, as a point of reference. In the video, you can see 66%, but that was a decrease from where it had been earlier in the day. I wasn’t confident that visible water vapor would reach the top shelf, but I’m pleasantly surprised! Please note that it is almost silent while running. I have my dishwasher running in the background in the video, and that’s what can be heard. Cons: - Every button press elicits a beep as well as when it is plugged in to indicate that it has power. I have it on a timer plug so that it turns off automatically along with the grow light. However, when the timer plug starts for the day, the beep from the humidifier sounds off. - It has no timer function on its own, nor a function that allows it to turn on upon power-up. So setting it up with the timer plug means that it won’t start when the plug does. I still need to start it in the mornings. It is a good value for the money, I just wish it had a few more functions and a way to set it to a “quiet mode.”

Excellent air humidifier with a large water tank. It has three fan speeds and two light brightness settings: bright and dim. There is also a night mode, which is practically silent. Very convenient and functional!

My 7 year old loves this thing, she request it every night before bed & even during the day if she takes a nap. It also helps with her allergies at night. Definitely would buy this over and over & super easy to clean! If your second guessing on buying it, DON’T! It is worth every penny.

The humidifier came packaged exceptionally well, with easy to read care and cleaning instructions. It's made from high quality materials and nothing feels cheap or flimsy. One of the warning labels did leave behind a sticky residue which was impossible to remove without rubbing alcohol, but at least the plastic underneath wasn't scratched or scuffed when I peeled them off. There are quite a few parts to remove and clean before and in-between each use, but given how dangerous mold can be, I actually view this as a good thing. The unit comes with a tiny cleaning brush, 3 (total) aromatherapy pads for essential oil, the instruction/warranty booklet, and a helpful quick cleaning guide. The humidifier is very powerful and produced a huge plume of visible mist the instant it was turned on. You'd really have to strain to hear it make any noise at all, as the unit is virtually silent. There is a rather loud beep each time any button is pressed, but these noisy beeps are the only feature I could see anyone having an issue with, everything else about this humidifier is fantastic. I'm very pleased with my purchase. There is an optional nightlight of a soft teal color that can be set to high, low, or turned off. This nightlight is quite pleasant, and if anything, I wish it were a bit brighter on high. You can see a little waterfall trickling inside the unit when this light is on. It's really cute, and again, totally silent. Just a few things to note: - Never add essential oils to the water reservoir, the instructions are clear that this will damage the unit. There is a little tray in the back with an aromatherapy pad that can be used instead. The scent produced is mild, as this humidifier is not a dedicated diffuser, but my orange blossom oil was noticeable and enjoyable. - Dreo customer service is out of this world! There was this little silicone ring not specifically mentioned in the cleaning instructions which I took it off to clean before first use, but I walked away to let everything dry and completely forgot how to put it back on. There are a few different places where the ring looked like it could fit, so I had to sheepishly write to customer support for help putting it back together. Tracy immediately sent me a custom-filmed video of how to reinstall the ring, which was way above and beyond anything I could have asked for. I've never had such a fast and incredibly considerate response from a company, it really blew me away. (Thanks again Tracy, you are seriously fantastic!) I'll include the video she sent me here, just in case anyone else is as forgetful or clumsy as I am. xD - The care instructions recommend use distilled water, not tap. This might be a factor for some people, so I thought I'd mention it. (But using distilled water is always best with ultrasonic humidifiers like this, otherwise you'll be breathing in all the minerals and particulates found in your tap water, and a thin white film will eventually build up all over everything in the area.) - The tank size is really generous, an entire gallon of water is needed to fill it up! That one gallon lasted all day and all night with the unit running on high, and I could definitely feel the difference in the air. Eventually had to turn the humidifier down to low, this thing really works. I am very pleased with this product and would definitely buy another. Super high quality, especially for this price point, and the company actually cares about its customers with phenomenal service and support. I can't recommend it enough, you should get one!

Overall, I like this humidifier, but the 36-hour runtime claim is pretty misleading. In my experience, it only lasts around 12–15 hours before needing to be refilled. That’s a significant difference if you’re buying it specifically for the long runtime like I was. On the positive side, it’s very quiet, which makes it great for a bedroom. It also has a nice design that fits in well with my furniture rather than looking like an appliance sitting out in the room. The lights are soft and not overly bright, and the controls are straightforward and easy to use. It can be a little finicky at times, particularly when getting it set up or operating it, but once it’s running, it generally works well.

Perfecto, lo recomiendo 100%. Mi iaia lo mecesitaba porque se le resecan los ojos durmiendo y el medico se lo recomendo. De momento 10/10. La bateria dura y cumple su funcion perfectamente

Honestly it changed the smell in the hall after starting Great quality as well

Wow. This is a great product. It has an excellent cool mist output that doesn’t leave the surrounding area wet. I have Sjögren’s disease which means I suffer from extremely dry eyes, airways, skin etc and have been struggling with cracked and sore nasal passages (it’s as awful as it sounds) and I can honestly say that after 3 nights use, I am seeing an improvement. I live in a hard water area and this humidifier has special cartridges that will help with that. It also doesn’t seem to have small output holes that will get furred up. The other, small and cheap models have all failed after a few months due to limescale. For the size/water capacity of this model, it is exceptionally good value. So far it seems good quality and has great humidifying properties. It’s really quite quiet too. I also like that you can turn the light off. Would definitely recommend.

Its working well

Tengo más de 1 año con él y funciona a la perfección, buen producto
