Question: What brand of water bottles does this thing fit on properly?
Document: I expected this product to fit most of the bottles that are sold in California, and by extension the USA. This product's manufacturer is located in San Diego, CA.to my surprise, when I received the item, it did not screw on to any of the 4 different brand bottles that I tried.I contacted the manufacturer, and they said it would fit onto Evian.I don't buy Evian water, since I think it's ridiculous to buy water that's shipped across the globe (and is more expensive).
I thought perhaps the filter was bad, but I cleaned the center silver part of my humidifier with a Q-Tip and it works well. Because I work in an office with many books, there is quite a bit of dust. To keep my humidifier working properly, I need to clean the top daily.The humidifier doesn't fit securely on any bottles, but it does set loosely on the top of a standard bottle, which is the reason I gave it 4-stars.
I travel a lot, and had another travel humidifier that stopped functioning after a couple months. So, I thought that I would go ahead and get something that was a little better quality. This unit lasted a grand total of 6 bottles of water before dying. I gave up on portable humidifiers; they just don't last even when properly cared for.
Underneath it has threads to screw down as a cap would, but so far I have found that am off-brand water bottle is the only one that it works with (tried five including the latter). Many water-bottles are using a plastic-saving, earth-friendly design, and the humidifier will only sit on top of these, NOT secure at all.- USB Cable was a tad short for safe use- LED light has no off-switch (i.e.
Because it does not work tried every thing spent money on bottle water and the only one that it fit on the way it should was the EVIAN bottle that cost me $1.97 for one bottle so it does not fit any bottle of water and still after spending all that money on bottled water it still did not work so SAVE YOUR MONEY  Was very up set and disappointed because this was one thing that I could have used do to my breathing problem
The worst product I ever bought on Amazon! The product doesn't fit many water bottles! I had to buy Evian for it to work! It really sucks!
I will try my best to be very careful! It did take me a few tries to get the thing to work properly. It is totally silent, but when it is working properly you will see the misty vapor coming out of the top. The first filter/wick I put in was not touching the metal inside the top of the lid properly so I had to manually adjust the wick to touch the metal panel that creates the mist. After that it worked fine.
I used this product in a small bedroom in a dry environment, and it did not perform. First, it is supposed to &#34;fit onto most bottles.&#34; I tried six widely available water bottles, including one of the bottles I have seen the product pictured with in advertisements, and it would not screw onto any of them.
Works great! Nice cool mist, not too wet. As others have said you need to find Evian water bottles but they fit nice and tight. our 'mood lighting' doesn't work but I'm just as glad about that anyway. I'm going to get another one for me. Oh, you can use a phone charger to power it by A/C too!
I bought this from a recommendation from my doctor. I have bad allergies and sinus problems during every weather change and since I'm traveling quite a bit my doctor recommended I invest in a travel/portable humidifier. I struggled to find a water bottle that this would actually fit and not just sit on the top of. Finally discovered that Evian bottles are the perfect size.
Answer: As far as I know, it should fit EVIAN bottles perfectly. In my case, I've been using Kirkland water bottles and work just fine.
