After researching different humidifiers, I decided to purchase this for my 92 yr old mother's senior living apartment. It has worked quite well; my mom's skin is not so dry and she doesn't complain about a dry mouth and throat when getting out of bed in the morning. I like the amount of mist it distributes at each setting. It is very quiet.

Great purchase and value as well. This humidifier is super quiet and easy to use. I like that there is a low, medium and high settings. Plus the option of using the light or not. The tank capacity is large and works well. I would highly recommend.

This is an excellent humidifier, it works great in my 12x12 foot bedroom. It's really bright, tho, so I had to rig up a cover for it and that works really well (I know I can shut off the light but I need a little light for reasons). The unit is absolutely silent. I run it on medium with a full tank and it will last 2 nights of 6-8 hours each, so I think the 36 hour runtime they advertise would be on low. I really like that the vent on top is tiltable so I can aim it towards our bed instead of straight up. It worked straight out of the box and I have had no problems with leaking. Very happy with it after 2 weeks of use!

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.

I bought 2 of these and I got them delivered today. Upon removing them from their boxes, the first thing I noticed, was how well they are packaged! I got them apart, and filled with water, and they work great! There are 3 levels of humidity to choose for what you need in your house, and mine are on the second setting. I have one in my front room, and the other in my bedroom. They are pretty quiet, more of just a light humming sound. I am using the blue light on the one in the front room, and I love it! It's not too bright, but is a pretty calming light. If you are looking for a humidifier for a room, this is a great buy!

Easy to use, easy to clean, quiet and doubles as a night light! I absolutely love it. Helps me not cough so much at night from the dry mouth/throat. Sleep quality has improved with use of the humidifier! The most output has three settings too, and the size is good for my bedside table. All in all a good purchase! 10/10! 👍👍👍

I rarely leave reviews, but I felt compelled to write one for this product because it has truly impressed me. From the moment it arrived, I could tell it was well-made and of high quality. The packaging was secure, and everything was neatly arranged, which was a great start. What really stood out to me was how easy it was to use. Whether you're familiar with products like this or it's your first time, you'll have no problem figuring it out. The setup was quick, and it worked exactly as described. I’ve been using it consistently since it arrived, and it hasn’t let me down once. The performance is outstanding. It delivers exactly what you need and more. One thing I particularly appreciate is how reliable and efficient it is. It has quickly become something I reach for regularly, and I can already tell it’s built to last. Durability is another major plus. It feels sturdy and well-constructed, so I have no concerns about it holding up over time. I’ve accidentally put it to the test a couple of times, and it has proven to be tough and long-lasting. For the price, I couldn’t ask for more. I’ve seen similar products that cost much more but don’t offer the same level of performance or reliability. This one strikes the perfect balance between affordability and quality. Customer service has also been top-notch. The company clearly stands behind their product and is available to answer any questions you might have. It’s always great to know there’s support available if you need it. In conclusion, I’m extremely happy with this purchase. It has exceeded my expectations in every way, and I can confidently recommend it to anyone. Whether you’re looking for something practical, reliable, or just a great value, this product is the perfect choice. I’m sure it will serve you well for a long time.
