Don't think just get it!
[This review was collected as part of a promotion.] I was grateful to receive this humidifier. It was something our household needed for awhile. The instructions were clear and precise. The humidifier was easy to assemble and set up. I started using it and almost immediately the results were noticeable. The air flowing through my bathroom and bedroom felt clean and crisp. It gave me the feeling of being in a freshly cleaned, everything new, room. I loved it instantly. It does require regular maintenance of cleaning it so it doesn't acquire buildup and mildew. I would definitely recommend this humidifier if your in the market for one!

Good humidifier if it wasnt so loud
Pros - I liked that this humidifier has a larger opening for cleaning and two openings to disperse the water into the room. The machine can run all night and not run out of water. Cons - the machine is loud and it sounds like dripping or running water. The mist isn’t powerful bc of the two dispersed options which might be fine for some but if you have had the Crane it is nothing as strong or quiet like that machine.

Must Have
[This review was collected as part of a promotion.] I love it. I suffer from pretty bad allergies, seasonal and animal allergies. This has completely changed the way I breath at night. It helps me sleep great at night. The instructions are pretty simple and maintaining it clean is so easy. I love the different levels of humidity that you can use. From very little to extream!

Calming Humidifier
[This review was collected as part of a promotion.] I am loving this product, I’ve used it over a few weeks and it does exactly what’s advertised. It is very quiet and soothing and perfect for a bedroom or office sized space. I haven’t yet used the essential oil feature but I plan to as that would be great for evening relaxation. I also think the size is great, it’s pretty compact and doesn’t take up a ton of space.

A great companion for mouth breathers
[This review was collected as part of a promotion.] Setting this humidifier up was a breeze, no confusing assembly required. For anyone who's dreads putting together new appliances, this one won't give you any trouble. I use it exclusively at night, and a full tank lasts 3 nights before i have to refill it. That's a solid runtime that keeps nightly maintenance to a minimum. As a mouth breather, waking up with a dry scratchy was a regular frustration. - this humidifier has completely resolved that. I sleep much more comfortably and wake up feeling noticeably better. I fill it using a basic tap water filter that doesn't reduce TDS, so in theory the mineral content is still present. Despite that, I haven't noticed any white residue or mineral buildup around the unit like the manual says might happen. Whether it's the filter or just good design, my surface has stayed clean. There is a spot to add essential oils, which is a nice touch in concept. In practice, I haven't been able to detect much of a scent when I use it. The diffusing effect seems fairly subtle. If aromatherapy is a priority for you, you may want to add a regular diffuser along with a humidifier.

Good size for my bedroom
[This review was collected as part of a promotion.] This humidifier is perfect for my bedroom. It gets really dry in the winter so having a small humidifier for my room makes it much more comfortable. It is small enough to blend into my room but holds enough weather that I do not constantly have to refill it. It is easy to clean and maintain. Overall I am very happy with the product.

Perfect for adding moisture back to the air in air
[This review was collected as part of a promotion.] Perfect addition to our home in perfect timing. The AC running during this hot season often dries us all up. Humidifiers save the airways! We basically have one in every room in my home at this point 😅. Love the look of this humidifier, and found a happy surprise in the included brush stashed under the tank. This one also has a pad for essential oils, easily accessible. It doesn’t take up a lot of space and is light weight, which is always preferred with devices like this. Overall, I’m satisfied.

Reliable effective night time routine addition
[This review was collected as part of a promotion.] The Honeywell Ultra Mist Cool Mist Humidifier has made a noticeable difference in the comfort of my room, especially during the dry weather and colder months. It’s easy to set up, quiet while running, and produces consistent, cool air that makes it easier to breathe while sleeping at night. I’ve noticed less dryness in my skin and throat when using it regularly at night. The design is sleek and compact enough to fit nicely on a nightstand without taking up too much space. Overall, it’s reliable, effective, and great for every day use.

Great for dry nasal passages
[This review was collected as part of a promotion.] This thing is awesome! I've plugged it in for fifteen minutes and already my dry nose opened up. Took it out the box, filled with water and plugged it in. Easy peasy. It has a gallon water capacity and an essential oil tray, how cool is that? Vents at the top so you can direct the direction of the cool mist and super quiet. This is for medium sized rooms and can run up to 36 hours. Perfect for dry, itchy skin relief and keeps throat and nasal passages hydrated, naturally moisturizes and helps reduce static electricity. Get you one..

Great product
[This review was collected as part of a promotion.] This is perfect for the winter time when needing to add moisture to your home. I have set this up in my bedroom and it has improved my sleeping tremendously. I dislike that the top separates from the base very easily so it does make it a little tricky if you want to move it from room to room. But overall this humidifier has been great!

Sleek and compact humidifier
[This review was collected as part of a promotion.] This is a sleek and compact humidifier. It’s a great option for a small spaces with simple to use controls (just a single knob). Of course, due to the small size, the overall capacity is relatively limited, but it has always lasted me throughout the night.

Happy camper!
[This review was collected as part of a promotion.] So nice to have a cool mist humidifier on almost summer time. It’s been hot the past few days and it helps it cool down inside my condo. It’s easy to use, reliable on my daily life and it’s not noisy. I just put a little distilled water and put more if I need it. I turn it off when I’m out of my place and make sure to clean it from time to time. Very cute, perfect size for my space and it’s been durable so far that I’ve been using it. Highly recommended!

Great humidifier that is compact and can be easily
[This review was collected as part of a promotion.] Love this small, portable, and convenient humidifier! It is currently on the floor of our infants room, as we have moved it from room to room to help battle sickness. Sore throats were alleviated overnight with the humidifier running. It is compact enough to conveniently move, and the dial allows you to fine tune how much humidity you would like. An easily accessible filter is also a plus!
