My Go-to Humidifier for a Small(ish) Room
This is my go-to humidifier. Buy a new one at the start of every winter for my smaller bedroom. 90% of the parts come apart for easy cleaning. Yes, it can get slimy pink mold if not cleaned regularly, but that’s the case with all humidifiers. The difference is if it’s easy to clean, and this one is! I take it apart and clean it once a week, takes 10 minutes, and never had a problem. Very subtle noise level that’s soothing and hardly noticeable. Lights can be completely turned off. Large water reserve lasts easily through the night. Creates the perfect amount of humidity in the room without being stuffy. Perfect for a small to medium sized bedroom. Highly recommend!

Quiet, easy to use, and works great
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.

GREAT company
I bought this humidifier in July and I demand a lot of it. It’s on for about 13 hours a day for my plants and it’s been great! It’s quiet, sturdy and it works fantastic. I love the wall of mist.About 10 months after purchase, I noticed the mist wasn’t being pushed out like it used to, even with regular cleanings. I emailed the company, Dreo, and they were incredibly helpful! They offered to send me a replacement without having to return the old one, so now I will have two working reservoirs at least.I already loved this humidifier but the company and their customer service has solidified my use of them for years to come

Get it. You’ll love it.
Very effective humidifier for this price range.I noticed my poor kitty was licking his paws excessively, and realized his nails and toes were really dry. I wanted a cheap humidifier that would fill the air of an 800 square foot room and the Dreo does it very well.I love the wide opening that the mist comes out of. It looks nice and is very quiet, even on high. A couple of complaints: 1. No matter what setting you choose, the same amount of mist comes out. It’s basically always on high. 2. It has the stupidest design for refilling. You can pour water into the top, but you either have to lift the entire tank out and carry it to a sink while it drips all over the floor, or you have to bring water to it with a jug or something. I found it to be messy both ways.Big redeemer: It’s designed beautifully for Easy Cleaning! Every single part can be removed and scrubbed or soaked. Since the opening of the tank is so large, you can put your whole hand in there to clean it thoroughly.I have really hard water, so I use half distilled, half tap. And I soak the mineral deposit buildup spots in pure white vinegar which breaks it down perfectly.

Dreo Never Misses A Beat
Love the sale they had for this. Very affordable. Arrived quick. I had a flu at the time of writing this review and not 5 mintues after i put this humidifier together and tested it, my chest and nose opened up. Definitely get you this especially for your household. It can definitely make breathing and sleeping better. Holds a lot of water. Very easy to clean, it comes with cleaning tools. The light is an added bonus, just makes sets the tone at night for a good night sleep. You can turn the light off if you want. Very quiet like i wouldnt even know it was there otherwise. Highly recommend all of their products. I have their portable air conditioner and fan and their products consistently been a pleasure to have.

great value for the money, whisper quiet
Quiet, you don't even know you have it on. Perfect for a bedroom. I suffer with severe dry eye and needed to add some moisture to our bedroom. This was very affordable so I was worried about the quality. The quality is great. I have been using it for 2 weeks every night and it has done what it's designed to do without disrupting sleep. Does have a light with 3 settings which I do not use but it does look nice. If you need a humidifier for your bedroom and are sensitive to sound this is your machine. Quiet, lightweight, easy to fill, clean, mists evenly. Easy set up and turn it on. Cool mist. I highly recommend.

Great Humidifier
This 4-L humidifier is what I decided on for my plants in a 4x4x8 grow tent to keep them in the tropical climate they need while growing before they'd be ok outside such a controlled environment. Super quiet operation, fine mist blows out strong like a fog but breaks down to invisible humidity within about 2 feet so you can see it's working great but disappears into the air beautifully, this shows the power and fine mist created.This humidifier is amazing IMO and for the price, it simply can't be beat. Arrived packaged well and easily put together, I run this non-stop on the lowest/night setting which perfectly keeps the humidity at around 50%RH, its super quiet and wouldn't even know it was running if I didn't see it blowing the mist. I keep mine going straight up because of lights and fans in the space but you can adjust the missing angle some towards the front or back so device placement isn't an issue and can be placed closely to other devices/furniture.The night setting (extremely low visual light on this setting) is great for me as I've said and most importantly is that the light does go out after a short period so won't interfere with night darkness that plants need. I refill the tank twice daily just because I'm checking all things twice daily but on the lowest 'night setting' this humidifier will easily last 30+ hours. Great product and I highly recommend it!

Dreo does it again
Probably as good or better than Dyson.If you’re looking for quality that won’t dip into your savings Dreo is it. I love this humidifier. People who need to add humidity into the home for very dry air that makes your nostrils bleed- you will notice the difference almost instantly. I tried to show the size with my boot for scale. Very nice sized humidifier and says it covers up to 200 sq ft. The air in my home is much more comfortable and I can breather easier and my plants are happy now! This is the blue Dreo with the light up feature which is full half or no blue light. Beautiful color as seen from the photo and sleek especially for those who like it minimal. Very easy to use and set up just get your favorite plant based spray on a cloth and wipe it down before use although it comes very clean already. Add distilled or filtered water that ensures no white particulate matter. Machine hold 1 gallon of liquid and evenly disperses. 3 levels of mist and water can last longer when used on lowest setting however on the highest setting it is still long lasting up to 40 hours. The rear has a little slot you push in for it to pop out add 5 drops of essential oils and you can smell it quite well it’s very soothing. Quieter than the quietest fish tank!Design, functionality, and description are all on point.Dreo may be my favorite brand ever for mimicking natural air flow and elements.

Works well for bedroom space, makes slight dripping noises
First night I used this I decided was going to return it because the dripping sound noise it made was annoying to me, I got another humidifier though to try out first and it didn't work nearly as well for the humidity, so I ended up keeping this one and used to the noise (I guess a lot of people don't mind it). I appreciate the nightime setting has no lights also!

No humidity sensor
It works great but it has no humidity sensors so it will run until it’s out of water and make the room swampy.

Si tu est pas bilingue tu devras te débrouiller seul
L’appareil est bien ,le seul problème est que tous les directives sont seulement en anglais. C'est un gros problème avec les articles qui sont fabriqués en Chine,soit aucun document explicatifs et encore moins des consignes de sécurité et d’entretien
