Has essential oil pop out which is cool!
[This review was collected as part of a promotion.] Great humidifier. Easy set up. Has an essential oil spot you push the button in and it pops out with ease. Mist comes out of two holes at a good rate. Easy to control the settings. Great overall quality for the price.

Misty dreams!
[This review was collected as part of a promotion.] This product was a pleasant surprise! I’ve never owned a humidifier before but this one was fairly easy to set up and get started. I will admit, I didn’t realize you pour the water into the bottom and flip it over so I ended up pouring water into the top of the machine and getting water everywhere. Once that was figured out it was smooth sailing! I love the adjustable water vapor setting. It feels nice to put my face over the mist. I put in some tea tree oil as well and it immediately permeated the room with the aroma! Overall I’m really happy with this, it was something I didn’t know I needed.

Simple, quiet, and effective humidifier with great
[This review was collected as part of a promotion.] Loving this humidifier so far! Setup was super quick and easy - literally just fill and go. The performance is great for my bedroom, and I noticed the air feels more comfortable almost right away. It runs really quiet and doesn't seem to use much power, which I appreciate for overnight use. The water tank is easy to refill with the wide opening, and cleaning is simple with no hassle. Big plus that it's filter-free, so no extra costs. Overall, such a convenient and reliable humidifier - definitely recommend!

Best humidifier ever
[This review was collected as part of a promotion.] This humidifier is the best humidifier I’ve gotten. It’s much bigger than the one I’ve had, it was relatively easy setup. There’s no filter required. It comes with a brush for cleaning which is a big plus. And the mist covers more space.

Simple, Quiet, No Filters-Exactly what I needed.
[This review was collected as part of a promotion.] I am very impressed with this cool mist humidifier from Honeywell, and the fact it is filter free is a plus. It saves money and maintenance is just so much easier. Set up was easy and quick took me under two minutes. It was easy to fill and easy to clean. Quick front knob turn on and is working in a second’s time, no ramp up period. And it is super quiet which is a huge plus as I will be looking to use it in the baby’s room. Overall great, low maintenance humidifier that does exactly what it is supposed to do. I would definitely recommend.

Dont do it
This worked great for about two weeks. Then it completely died. Started with omit coming out and then it just would not turn on. I reached out to the warranty center and that’s an even bigger joke. You have to put in a ticket online and they say up to 6 business days to get back to you. They never do. When you call, they say all reps are busy and hang up on every time. Save yourself the trouble and get something different.
