PureGuardian Ultrasonic Cool Mist Humidifier, 10 Hrs. Run Time, 210 Sq. Ft. Coverage, Small Rooms, Quiet, Filter Free, H920BL

I just ordered this humidifier for my desk at work. The long very cold winter was torture on my skin and sinuses and luckily my job approved me to bring in a small humidifier. Such relief!I didn't want USB plug in because we are not allowed to plug personal items into our computers. Plus they seemed way to small.It is extremely quiet, even quieter than a larger good ultrasonic competitor brand I've used at home. It is quite small, which is what I wanted. It is very easy to fill and much lower maintenance that larger humidifiers. I keep it on the floor half under my desk and no one even notices it. I wanted it to be discreet since I had special permission. The shape is perfect because the mist puffs up vertically at a slight angle which can be adjusted by turning the nozzle. I keep it puffing toward me as I sit in the chair. Some of the other personal humidifiers may have required me to keep them up on the desk based on the angle of the mist I saw in their pictures.I chose this model partially because of the positive reviews. I didn't want to spend a lot since it is for work use so I bought the "used" Amazon Warehouse deal with damaged packaging. I don't know the details but it seemed to be brand new. But they probably couldn't sell it as new because of the box or maybe it was a returned item. The box was taped closed and one corner was a crushed but it really wasn't all that damaged of a box. I was pleasantly surprised.Another reason I chose this model is because of the nice pretty shape. It's almost a shame to have it hiding under my desk. The blue light is very pretty but of course I don't use that at work. It is useful if using it at night so you won't trip. I can see how it might be too bright for some people but I don't find it that bad as long as it is not in your direct line of sight. I did try it out at home before bringing it in. It was enough to add decent humidity to my medium sized bedroom.One con is that it is labeled for ten hours but it only seems to last about eight. Perfectly fine for work, and very easy to refill. One tank full gets me through the day, shutting it off for lunch. This is on low speed only. But I can see how using it overnight this might not be long enough. I haven't run it yet for a long time on high but I would imagine around five hours before a refill.The mist output is really impressive for a small unit. Even my coworkers that have seen it running are impressed. The unit seems very well built and I hope it lasts me many years.I think this unit is great and I gave five stars! I would definitely recommend this humidifier for anyone looking to purchase a smaller personal unit.

I have small bedrooms, and the dry winter air prompted me to look for humidifiers. The ones from the big box stores were always too large for the limited amount of space available to me, so I went on the hunt. I found these, and they're perfect. They're slender, utilizing the space and putting the mist into the air rather than over the table it's on, like my older one. And it's not at all ugly. In fact, it's now doubling as a nightlight in the kids' rooms because of the optional blue light under the tank. It's not too bright for us in our small bedrooms. It's quite a pretty blue, and my daughter likes that you can see the reflection of the water on the wall. It's a very quiet humidifier, which is very pleasant. You almost forget it's even on! But it lasts all night, and the button turns red when it's empty, so no worries. The only thing I'd improve on is an auto-shut off. The tank fits beautifully under my sink for an easy fill up before bed. The box comes with a brush, too, which I find very useful, as not everyone has a bottle brush. I imagine it's quite easy to clean when needed, which shouldn't be often because of the Silver Clean coating. I'm glad I bought these!

I just got this not that long ago but I do have to say that I really like this humidifier. I use it in my bedroom at night and it sits on my nightstand right next to my bed. It works really good and really helps with adding humidity to my room when I sleep. I actually plan on ordering another one for my 4 year olds room as he is prone to a lot of congestion and what not. The top white piece can be moved so you can kind of direct where you want the "mist" to go. The mist that comes out is visible. Refill is easy as all you need to do is grab the blue piece off the base and unscrew the bottom and fill it up. Another pro that I like is even though it is right next to my bed and on my nightstand, I have had no issues with any damage to the wood. The final pro is the nightlight feature. It is bright enough to work as a nightlight but not that bright that I can't sleep.Now with the cons. It says that it lasts for 10 hours. So not true. I turn it on around 10:00 or so at night and by 6:00 or 6:30 in the morning I am woken up by it beeping at me for low water. I also don't like that you have to press it so many times to access the different settings. You press it one time it turns on low, 2 times is low with nightlight and 3 and 4 are the same thing but on high mode. When the water runs low and needs a change the power button will glow red and you get that beeping I mentioned. So really I wish the length of time was longer but I knew that before buying thanks to the reviews. Overall, I would still buy it again.

Wish the tank was bigger and that it was top pour, but it works great nonetheless. Very quiet! Perfect for personal spaces around plants or a very small room.

This the second identical humidifier I have purchased. The first one purchased 2-3 years ago and used in the cold/dry months is still working. The second one for which this review reflects, was used last winter without incident. This winter, starting around mid November, worked find until mid to late December when the blower quit working. Well, since having an engineer for a husband, we purchased a replacement blower, he installed it, and the humidifier is again working well.
