   Very effective at humidifying, but has some minor issues, July 22, 2015

   Vine Customer Review of Free Product (What’s this?)

   This humidifier uses ultrasound to vaporize the water into a cool mist. The main advantage to a “cool mist” humidifier is that it begins producing mist as soon as it’s turned on. Some people prefer to use steam humidifiers, however, because they boil and sterilize the water, and don’t eject live mold or bacteria into the air. This humidifier does not boil the water at all; if you use the warm mist setting instead of the cool mist setting, all it does is warm the water to about 80 degrees before it vaporizes it (which actually makes it easier for bacteria to thrive). If the humidifier is maintained well and cleaned periodically, this shouldn’t be a problem, but I wouldn’t recommend sticking your face into the mist and inhaling deeply.

   Regarding the warm-mist setting, it speeds up the humidification of the room. Because it heats the water to only 80 degrees before it vaporizes it, I can’t imagine it would be very effective if the water starts out warm (especially during the summer), but in cold temperatures I could understand how it might help. (The mist itself feels almost the same whether you’re using warm or cold mist.)

   I like the other features. One is variable mist output – I can adjust the amount of mist that comes out. On the fastest mist setting, running constantly, a full 2-gallon water tank lasts a little under 2 days (~43 hours, actually). You can make it even faster by removing the attachments. I haven’t tried the lowest mist setting for extended periods of time, but based on the level of mist coming out, I bet it would last the full 120 hours as advertised.

   Probably the most useful feature is the desired humidity level; you can set the humidity anywhere from 40% to 75% (in 5% increments), or you can tell the humidifier to run constantly. There’s also an optional timer, so I can tell the humidifier to turn off automatically after a period of time. The room’s current humidity is displayed on the screen.

   When “auto” is enabled, the humidifier automatically uses warm mist, keeps the nightlight on, and sets the desired humidity to 50%. Kind of pointless, because those are all features that I can easily set myself.

   I really like the vertical extension. It’s basically a pipe which takes the mist about 4 feet above the ground before releasing it into the air. This allows for more even humidification, because the mist is heavier than air and sinks downward. There’s also another attachment which goes on the end of the tube, and can be used to direct the mist. I prefer not to use it, because it restricts the airflow, so a lot of the mist collects on the inside and runs back down into the humidifier. This slows down the humidification process.

   The thing I find most annoying about the humidifier is that it has a bright blue display that won’t turn off. If I’m running it in my bedroom at night, I have to cover the display with some cardboard so it won’t keep me up. The display is bright enough to illuminate objects in my room. It wouldn’t be so bad if they used green or red light, but blue is the specific color that prevents sleep. I hate to think how bright the nightlight would be, but thankfully that can be turned off.

   Another problem I noticed is that the water in the vaporization area gets a slight off-odor if it sits for a couple days without running it. The obvious solution here is to pour out the water when it isn’t being used, but now I wonder whether the inside of the tank is the only part of the unit with antibacterial properties.

   So to summarize, it’s a pretty cool humidifier (pun intended), and has a lot of useful features, but it does have minor issues.

   Pros:
   + Very quiet (regardless of the settings).
   + Adjustable mist output. Nozzles can be removed if necessary, so the mist will come out faster.
   + Large 2-gallon tank lasts almost 2 days when running at highest setting, 5 days at lowest setting.
   + The humidifier maintains a specific humidity, or can be told to run continuously.
   + Comes with a vertical extension, which brings the mist 4 feet up into the air.
   + Cool mist will slightly cool the room in Summer.
   + Unit without water is very light, making storage easy.
   + Has an optional built-in nightlight.

   Cons:
   – The bright blue display cannot be turned off at night.
   – Only the tank seems to have antibacterial properties; the other parts of the humidifier are unprotected.
   – Uses ultrasound, so water is not sterilized. If tap water is used, minerals are released into the air.
   – The buttons respond to a very light touch, and can be activated when accidentally brushed against.

   Great in most ways., February 15, 2015

   Well in most aspects this humidifier deserves 5 stars but in two ways it does not. The first being the lack of “warmth” in its warm mist. I do feel a difference between the cool and warm settings, but it can best be described as subtle. The second thing wrong is the accuracy of the hygrometer. I actually have two of these humidifiers and was surprised to find that both suffer from this problem. Actually accuracy isn’t the right word, their hygrometers are totally off. I decided to put them side by side in the same room to experiment. After two days running side by side, one unit read at 20% humidity while the other was 15%. Using an accurate hygrometer to get the real humidity I found it to be 39%-41%…now that’s off. Despite this I’m still giving this humidifier 4 stars (it deserves 5 stars in every other way) because there’s one thing about it that simply goes beyond 5 stars…..no need to constantly keep replacing filters and cartridges (and spending money on that crap) as well as very simple cleaning/maintenance (so far at least). To me this makes this humidifier the only choice and on another level from all other humidifiers requiring that stuff. Beyond that this unit is very quiet, looks very slick, and has relatively simple operations. I appreciate its cool blue night light (although many complain it’s too bright, I don’t think so, I like it), which can be turned off if not needed. All in all I’m glad I got it and believe its actually helped calm my allergies some. As a final note I’ve read some complaints that it did not raise the humidity level in a room appreciably (if at all). This is not the fault of the humidifier but more likely the air circulation in your house. I’ve also experienced the same thing. The humidity in my average size bedroom has only increased by 5%-8% (when only one of them is running). A humidifier can only be fully effective if its not trying to keep up with the ventilation system in your house. ANY humidifier would give the same result. This humidifier has a 2 gallon tank which needs to be refilled every 18-19 hours when on the highest setting. That’s about 2.5 gallons of water being shot into the air every day…..if your room isn’t being humidified by that then there’s something else going on. Overall a good quality hassle free humidifier.

   This is one of the best humidifiers I’ve even used. It’s virtually silent even running on “high”. The tall extender releases the mist higher into the room which makes it disperse more efficiently. Very easy to fill and no filters to mess with. I love it so much I just bought a second one for another large room.
