  • Great Product!
Color: White Size: 4L
Really like this product so far! It have been working out great for us, we live in a very dry climate and when summer comes around my wife tends to struggle with allergies and other issues brought on by the dry weather. I have used humidifiers in the past and none of them seemed to work very well and I would end up giving up on them after a few uses. Not with this one, it is super simple to set up and use, it is quite and doesn't disturb you either during the day or at night. I ran my all day at high and then refilled it and have been running it on low ever since and I can tell a difference in my room air as well as my quality of breathing as well! I also like this product because it doesn't require distilled water but either ultra purified water or distilled so it makes refilling it for me quite simple and hassle free! ... show more

  • It's very quiet.
Color: White Size: 4L
We've used it for 9 months. It puts out more vapor than others we tried and is much, much quieter. Using distilled water makes a big difference in how long it goes between cleaning and how hard it is to clean. 6 gallons lasts about a month and costs $1.25 a gallon at Walmart.

  • Perfect
Color: Black Size: 4L
We've had this for about 6 months now and it works great. It gives off quite a bit of humidity and I appreciate the large tank. On low, the whole tank lasts 2-3 nights. I use distilled water and haven't had any issues cleaning. I really appreciate night mode that turns off all lights, even the status light. ... show more

  • Be careful with these humidifiers!!
Color: Black Size: 4L
Guys, right off I must warn you that while these portable humidifiers do the job of raising the rooms ambient humidity, there are a couple of things you must know and avoid. I'm a male and I spent several weeks suffering from back to back colds that I could not shake. These colds would turn into the flu and I eventually got bronchitis. Upon finding out my rooms humidity was in 20% I went out to buy these. So this is my second unit. My first one was not powerful enough in really cold temps so I got this one. My first mistake was setting it up right next to me at the foot of my bed about a foot away from my head. These type of humidifiers releases a cool draft of air that is hard to tell where its coming from. So while your trying to get that humidity up, if your sleeping and that cool air is right on you that defeats the humidity benefits and I was still waking with the sniffles. I even ran my hand all around the unit to try and see where this cool air was escaping from but was not able to tell. So once I moved the humidifier to a new location, viola, problem solved. Maybe this is mentioned in the manual but I did not see it. So I highly recommend this model as it easily last all night for my 90 square foot room at the highest setting even in sub zero temps.. So thats the second thing about these humidifiers. Be sure to do your homework on what to buy. Based on your square footage room (lenght X width= square feet.) Plus the outside temps and your current room humidity (should be between 30-50%). Yes your going to need to buy a thermometer/hygrometer for that room though there are some units that has it built in. ... show more

  • Great humidifier!
Color: White Size: 4L
This humidifier is great! The tank is larger than my old one, but I feel like I have to refill it more often than the old one I had. However its output is amazing as this thing is nearly silent. I sleep with it right next to me and it doesn't bother me at all. The tank is easy to get backwards so before you put it to use I would recommend making a mark on it and the base so you know which way it faces when you take it off for cleaning. I just did a little streak of permanent marker and line the lines up. The refill from the top is my favorite part, its so easy! ... show more

  • Mists up into the air, no table condensation issues
Color: Black Size: 4L
I purchased two different humidifiers, one for the upstairs and one for the downstairs. The other one was fancier, with more buttons and features, and had a larger tank. I knew it was a knock-off, but sometimes they are just as good as the name brands. Well, I have to say that in my case, the name-brand was 100% worth it. This unit doesn’t have all the bells and whistles and I run it at full capacity constantly (so have to refill it more often than I would like, since it’s only 4L), but the mist actually goes UP into the air instead of immediately settling on the table. It has the power to do that, since the product focuses on the core functionality of the item. I have incredibly hard water, so I have it filtered through one of the zero-type filters. So far (about a month in), so good. I’ve washed it with a touch of dawn and warm water a few times, and there is no smell. Super easy to clean. Eventually I’m sure I’ll use vinegar to descale and clean a little more thoroughly. But for now, I could not be happier with this product. I’m really glad I bought the other one, too, or else I’d think that I over-spent on a basic item for the name brand. In this case, it really is superior quality. It was obvious just from the unboxing that it was made of better materials (and yes, you can totally tell when plastic is thin and cheap). But the fact that the other one just didn’t even do the core functionality well-enough - astounding. Anyway, 10/10 I would recommend this one to my family and friends. Also, raising the humidity in my home and especially home office has reduced my eye blurriness/irritation/eye fatigue so much. If you’re thinking of getting a humidifier for that reason, I def recommend you trying it. I had a noticeable difference in about 3 days. ... show more
