  • Great for a Nightstand
Color: White
My old humidifier gave out, so when I had a very stuffy nose, dry eyes, and slight cough (allergies) this spring, I looked to Amazon to buy a new one. I chose this one. I was surprised at its small size, since the one I had been using was probably three times larger. I wanted a larger one, but it was my fault I didn't get one. The dimensions for this one are clearly marked on the product page, and I failed to look at them. I just noted that I would receive it the next day, and that was good enough for me. This is a humidifier more suited to an end table than to the floor. Nevertheless, I placed mine on the floor, and it worked well. The steam seems to come out more in one direction only than with my older, larger humidifier, but that's to be expected. This little humidifier gets the job done, though, and done well. After only one day of use, my eyes, nose, and throat were feeling much, much better. I continued to use the humidifier through allergy season, and now I'll put it away until next year. This humidifier is so easy to use, You just fill it with water, plug it in, and turn it on. I do like the fact that I can adjust the level of steam that comes out since sometimes I need more, sometimes less. This would be great for a child's room when he or she has sniffles or a cough. Small as the humidifier is, it doesn't tip over easily at all. Now, a rambunctious child could easily knock it over deliberately if he or she were inclined, but It would have to take a deliberate action. Cleaning this humidifier is so easy. Just rinse the water receptacle, keep it clean, and that's it. When I need a new humidifier, I'll probably go for a bigger model, but until that time, this one fills all my needs and fills them well. Highly recommended, especially for a bedroom night table. ... show more

  • A must have
Color: White
Why did you pick this product vs others?: My kids got sick and our old dehumidifier was molded. Grabbed this one in a rush and GLAD I DID. It's small but lasts all night (even in their large bed room). I've repurchased for every bedroom in the house so we all have one when needed.

  • So far, so good
Color: White
I have used two of these humifiers for two years and they work very well. My only issue is that I wish the water tank could have been made larger. If I turn it to max output it will run dry in less than eight (8) or so hours. We use one of these in our bedroom and run it while we sleep. Other than that neither humidifier has had a single issue. They are also useful to humidify my guitar when I use it. I use both distilled water and tap water without any problem. It would have been nice if a small brush would have been provided to clean it. ... show more

  • Excellent Product - Don’t Forget The Spout!
Color: White
EXTREMELY IMPORTANT! When you unpack the box, there is a small package with a spout cap and brush. These are both critical pieces. Do not be tempted to use this machine without the spout - if you do, everything around the machine will become drenched quickly. I couldn’t be happier with this humidifier. The tank is big enough that it lasts through the night, even on the upper power levels of the dial. Out of the box, it’s very easy to set up. I cannot stress enough the importance of the spout cap though. It comes in a small packet and I assumed it was either an enhancement or possibly to be used for storage. Nope! If you turn it on without the spout, you will be enchanted by the massive puffs of lovely humidity coming out and think that’s all you need. But the fact is that huge clouds like that are heavy - too heavy to float away from the machine. They settle and condense immediately and very quickly, you’ll have a pool of water; not only on the surface you’ve set the machine on but it will soak whatever fabric might be nearby. The spout not only prevents this, it’s remarkably effective at directing the mist and pushing it further away from the machine and higher into the air. The provided brush is marginally useful for cleaning the rubber inside parts. But be sure to do this, especially if (like me) you choose to ignore the warning not to use essential oils or other non-water liquids. About adding oils: The oils WILL erode the plastic tank and fan mechanisms or even clog the wet wicking filter. There is product called Vicks Vaposteam that seems to be more effective and safer. My research shows that it’s less damaging to a humidifier because it has a high alcohol content so it evaporates and doesn’t clog as much. Edited to add: “Doesn’t clog as much” means it still clogs it. The oils WILL gunk and clog up the parts, sooner than later. I learned this very literally 3 minutes after posting this review. I looked over at my adorable little humidifier lovingly and noticed the bright red placemat I’d set it on was…maroon. Lifted it up and discovered it was saturated. Not because of a defect in the product, but a defect in the user. I’ve been adding nasal passage clearing oils to help with a cold and didn’t clean it out before adding more to the next water refill. Sure enough, because it’s a cold mist humidifier, the oils sank to the bottom and solidified near the drain. Backed the whole thing up. It took boiling water and a toothbrush to scoop the goop. About cleaning: Especially if you add an oil but even if you do not, debris and gunk will collect at the bottom of the tank by the rubber parts and wiping them away doesn’t get everything out. Oil will attract even more gunk and can very easily create molds and bacteria’s which, if you don’t clean out, will spew into the air with your mist. This really has been a great product and value - I plan on ordering a couple more for the holidays. ... show more

  • Perfect Little Humidifier for Small Spaces
Color: White
This small humidifier has been a great addition to our room. It works really well even in a smaller space, and it's impressively quiet — perfect for nighttime use. One feature I really love is the adjustable nozzle. I can easily redirect the mist without having to move the whole unit, even in the dark. We once misplaced the nozzle and reached out to customer service — they were fantastic and helped us quickly and kindly. Highly recommend this if you’re looking for something compact and reliable! ... show more
