Quiet, Powerful, and Perfect for Bedroom Use!
I’ve been using this humidifier for a few weeks now, and it’s easily one of the best I’ve owned. The 4-liter tank lasts all night on low mode, and I love that it can run up to 15 hours without needing a refill. It keeps my bedroom air comfortably moist, which has helped with dry skin and congestion.The built-in humidity display is super convenient—I can see the room’s moisture level at a glance and adjust the mist output manually. The top-fill design is a game-changer: no more awkward flipping or spills, and cleaning is a breeze thanks to the wide opening.I also appreciate the customizable mist settings and the 8-hour timer, which makes it perfect for overnight use. The aromatherapy tray is a nice touch, and sleep mode is truly silent—no buzzing or dripping sounds to disturb my rest.Overall, this humidifier is thoughtfully designed, easy to use, and very effective. Highly recommend for bedrooms, nurseries, or anyone needing reliable moisture and comfort!

The whole lid opens for cleaning, amazing
Great humidifier, been using this for about a month and been good, help relieved my dry skin during this winter. I live in a small apartment and because of the very cold temperature the heat has been on full blast. The humidifier helps with my stuffy nose and dry skin from the over heat. I like the design it has a small form factor since my bedroom is small, really help save space. Also the entire tank and the whole lid can be remove for easy cleaning, I had many humidifiers in the past and all had this small opening, impossible scrub; but this one is great that I can completely reach and physical clean all area of the tank, this is a complete game changer, I don’t know why was not thought of in the past. It was pretty easy to use, just fill up to the line and put back on the machine. Very quiet, I had it next to my bed and I don’t hear the motor at all. It shoots out a very strong fine mist, so the will not be a pool of water next to the machine but I recommend putting some towels or rags next to it.

This humidifier works great in a large bedroom, however it makes a bubble noise as water fills the conversion chamber. I do like the top fill as you do not have to move the unit. When I received the unit it did not work. I emailed customer service and got quick response and got the unit working.

What is it supposed to do?
The product is very simple and can pretty much take it out of the box and use it without having prior experience with humidifiers. This is the only good thing I can say about this humidifier. It’s advertised to be used in the bedroom. I’ve been plagued with a sinus infection for nearly a month due to use of oxygen after being hospitalized. I was informed a humidifier would help with decongestion especially at night. I purchased this product and spent an extra $12 on essential oil to put in for decongestion. The humidifier emits a mist into the air…but that’s where it ends. No scent, no change in humidity in the room… just a steady mist that goes straight up in the air and evaporates. I’ve used distilled water, spring water, tap water, I’ve followed the instructions and even invested time watching videos online. At the end of it all, a week later I am still congested and this product is worthless to me. Waste of time and money I don’t have to waste!

I love this ultra sonic humidifier. It is quiet and non intrusive at night time and performs as I was hoping – it definitely adds humidity in the dry air in my condo.I especially love the top fill ability. The entire top assembly can be removed to fill or to clean out or, the top cover can stay in place and be filled via the open grill. See video and picture attached.There is a small fan in the base of the unit that helps move the mist up and out and that is not a source of intrusive sound at all.The display goes out after a few minutes of use when on so the light isn’t a nuisance at night time and a simple touch wakes the display up.The only possible negatives are: 1) the outlet port of the mist is not an adjustable nozzle or directional. It simply emits the mist straight up, which for me and for my use is more than adequate and 2) there is no cover over the top grill to prevent dust from entering the reservoir. But I clean this regularly so I’m not overly concerned about that.I am happy with this humidifier and would highly recommend it.I only use distilled water in it so no white mist or unnecessary costly filters needed.

purchased this humidifier on the prime day. It was a good deal , and satisfied with its performance. It runs quietly, the mist output is steady. it looks small but can fill enough water to run through the night, and great on my desk.

1 star too much. Top cover is not easy to remove as it is almost flush. No handle to help remove. Does not go back on easily. Water tank is also tricky to handle. I get a lot of white dust even when using recommended water. The pad for essential oil is under the machine and not able to get too when water in tank. Cleaning is difficult. I would not recommend this unit.

Where do i even begin because this has been a life saver. My room had a funny smell due to poor ventilation but this humidifier did its job 100%. No funny smell at all. Cool air through out especially when i put in some few drops of Peppermint Essential Oil in the water.
