DREO 4L Humidifiers for Bedroom, 36H Runtime, 28 dB Quiet, HM311 | Easy to Refill & Clean, BPA-Free, Nightlight, Supersized Air Humidifiers for Large Room, Baby Nurseries, Plants, Indoor

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.

Best humidifier I've ever had. Holds a solid amount of water, is very quiet, and it's helpful. Easier to clean than most other humidifiers I've had, but still has some hard to reach spots. Other than that, no issues. Light has variable adjustments, I keep it on low, can't notice it during the day but it has a nice glow at night. Would buy again.

Really happy with this humidifier. The top-fill design makes it super easy to refill without any mess, and the 4L tank lasts a long time so I don’t have to constantly check it. It runs very quietly, which is perfect for sleeping, and the mist output is strong enough to noticeably improve the air in my room. I also like that it’s simple to clean and maintain. Overall, great value and definitely worth it for a bedroom setup.

I have 5 Dreo humidifiers in all, a newer version of this model as well as this model. Pros - quiet and effective. The light settings are lovely, I don’t use them much in main living areas but my kids love the light features for a gentle night light. Mist is cool, fine, and travels well in the air. Cons - so this is where I am really struggling with these units. The projection of the mist is so upright and narrow that it shoots more than 40 inches high. You WANT the mist up high for the best distribution of the heavier (water dense) air - i.e. your humidity. So I understand why it’s a feature to force the mist so high. And most furniture surfaces we might place this on are high up. However, you can’t actually aim the direction of the mist almost at all, period. The tops (both models I have are the same) have an adjustable top to direct the stream of mist forward or back - a fraction of an inch! It does not actually help, at all. So, if like most people, you set these units on a piece of furniture the height of a tall dresser or perhaps a short bookshelf you will saturate your ceiling. (See photo of green unit). If you put these things on a plant shelf, you’ll have huge droplets of water collecting on the underside of the shelf - and if you have grow lights, well, those are soaked now, too. (Photo of white unit on a shelf with very tall plants). In a desperate attempt to avoid mold and damage to my ceiling (or electrical components to my lights) I folded a thin vinyl notebook cover into an elbow-shaped-tube (green unit in the photos). This is both a very obnoxious thing to have to try to fix as well as an overall hazard. Many many competent designs exist to allow you to direct the flow of the mist away from items that could be damaged. My makeshift “tube” collects water (of course it does) and drips so I also have my unit sitting inside a plant tray. This is entirely too many steps to make it safe to operate my units around things like ceilings, walls, furniture, lights, and plugs. I don’t know about you, but those are all extremely hard to avoid in every house I’ve ever been inside. Eventually I will grab an angled funnel from my local automotive store to replace the make-shift tube I made to get by. By the time I buy funnels and plant trays for every unit I really start to resent the extra steps, costs, tweaking, and daily mess to maintain in the name of safety, which should be a key consideration in the design of an electrical appliance that you fill with water. Tips: Remove ALL packaging. Start on low, run for a day, gradually work your way up until the humidity is where you need it. Use distilled water only, sorry! If you want it to last and you don’t want to take it apart and clean it incessantly, used distilled water. Tap water and drinking water will introduce minerals, chlorine, and bacteria which will shorten the life of any unit from any brand and will increase the frequency of which they need to be cleaned. Put something underneath it! ALL humidifiers function by super-soaking the air with water. Surfaces nearby collect water, that water forms drips, drips make a mess. Place your unit inside a plastic tray, dish, or tote. Don’t overfill it, for real.

I suffer from asthma so this humidifier has helped a lot. comes with a lot of features which are nice like auto shut off, the lighting is not too strong for the bedroom and and operates very quietly. And I've kept the humidity in my room at a good level and helps me sleep . The nozzle is adjustable so that you could keep the mist away from you. it's a great buy for the price.

I get spontaneous nose bleeds in dry weather, or if I'm indoors a lot and the heat or A/C are on. I had my nose cauterized and it made no difference, so I have humidifiers on in my home almost every day. For years I used a different brand of humidifier and it worked well, but it was the type where you fill the tank, then have to turn it over to place on its base. I have some permanent damage in both hands which made doing this painful and over time it caused some real problems. Also, this other humidifier is rectangular and has more removable parts, making it surprisingly difficult to clean, at least for me. This Dreo top-fill humidifier is elegant in its simplicity! So easy to fill and to clean and it works even better than the bigger, more complex one I'd been using for years. In very dry, cold weather I had to have two of the other brand on at the same time to keep the humidity up, but one Dreo is doing a great job. I can actually see (as well as feel) that more mist is coming from the one Dreo. The real surprise is that the Dreo cost half as much as the other brand! I bought two of these just in case, but I don't think I'll ever need both on at once as I did with the others. How great is it to have something more efficient, effective, simpler to use AND less expensive?

This is the easiest humidifier to clean! I love it so much! It’s so quiet and has great output! You can also adjust the direction of the mist and it has a night mode where it turns off all the lights on it. So simple to use and I don’t have to refill it every night before bed! It lasts 2-3 nights. It has two nightlight settings as well but I don use it. As someone with terrible allergies all year round I love how every single part of this humidifier can be taken apart and cleaned! I would definitely recommend this to anyone looking for a cool mist humidifier.

SUPER QUIET!!! This is a small unit that delivers HUGE results. It fits perfectly on the top of the stair landing and is so quiet you cant even hear it at night. The direction vent it a great feature as I could point away from wall/ceiling and direct the mist exactly where I wanted. There is also a mist control that I changed for day and night. Do use distilled water to avoid the white residue and buildup. The fill-up process was easy without making a mess cuz the top comes off an you can fill from there, not having to lug the container around to the sink dropping a water trail like other brands do. There is also an auto shut-off so if it runs out at night it will turn off which is a great safety feature. Will be purchasing an additional unit this fall for work desk.

Ottimo colore, ottima funzionalità umidificante, ottima luce e luce notturna e funzione notte. Peccato che non si programma.

Good humidifier ,excellent value for money,easy to use lasting 3-4 nights between refills

After trying several models, this is truly the best humidifier I’ve ever used. Have slowly replaced all the humidifiers in our house with this model and won’t even bother trying others in the future. This is the first and only humidifier I’ve seen (aside from those super expensive stainless steel ones) that is truly easy to clean and hygienic. Other humidifiers have small crevices that are hard to get to, but ever little inch of this model is accessible and easy to clean. On top of that it has a ton of great things going for it: - very quiet - has a light that can be turned on or off (great for kids rooms) - good sized tank (will last two nights if on medium mist) - most importantly, functions well and puts back a good amount of hydration into the air, with three miss levels. Excellent value for money. Zero issues with leaking, and we’ve had our first one for almost a year. 10/10!

Its working well

Ein wirklich tolles Gerät. Großes Fassungsvermögen für Wasser. Läuft sehr leise. Mit Beleuchtung was sehr gut aussieht und noch etwas Ambiente ins Schlafzimmer bringt. Die Menge an Wasserdampf ist wirklich super und ausreichend für ein großes Schlafzimmer. Merkliche Verbesserung der Luftfeuchtigkeit und somit Schlafqualität. Mit 3 Stufen kann man die Stärke einfach wählen, alles per touch pads die gut funktionieren. Night Option mit Timer ist auch toll und praktisch. Ich bin also rundum zufrieden und kann das Gerät weiterempfehlen.
