Question: How long does it run on a full "tank" of water?
Document: Just as described. Plugged in and followed the directions to set up waited the 5 minutes to soak and gave it a test run in the house. It ran for 8 hours non stop and still had water left over. Puts out enough vapor that should be great for a car, just the right size for a cup holder and the cord is long enough to reach where ever you want to put it. Has two settings, continuous, and a 5 second run and 10 second break.
Of course not, but I don't have full room. I run it near my bed and feel the difference without seeing it.3. Endurance - it really amazes me how long a fill lasts, I feel like larger humidifiers go empty before I go to bed but this guy can go all night! (insert whitty remark here)THE NAYSI can't even number my nay because it's completely lame, but the vendor included an offer to receive 2 free filters but the offer only lasted 2 weeks.
I have a long commute everyday in the dry southern California weather and used to suffer from super dry skin and hair, no matter what beauty products I used. Now I feel like I just took a walk through the rain forest when I come out of my car - my skin is glowing and plumped up, my hair is full and bouncy. The only tiny little thing is that once there's only about 1/5 of the water left, the humidifier no longer works.
I purchased this product due to extreme dry eye problem. Although the unit is small the space inside a car is also limited. I find it very difficult riding in a car for any period of time. This product has helped put some moisture inside for which I am very pleased with. I would certainly buy again and bring extra water for long trips.
I got this humidifier to be used in may car, since I have a very long commute. I used it during the entire duration of the commute, and I can feel that it is generating a less dry environment in the car. It produces a thin stream of water droplets that can be either continuous or in intervals of 10 seconds. There's a blue light next to the stream, so at night it produces a cool blue stream of water.
&#34;I needed this product to use in my SUV as to help me with the air quality in vehicle to give it some moisture. I use it in my cup holder which is next to me. I'm glad that I was able to find a car humidifer & lucky to have run across this. I like it because it is easy to use and hopefully has helped me on my commute back and forth to work.&#34;
Too soon to review its performance. But it floats nicely in the cup of the dead beauty. So maybe I can use it in the car that way, trying not to spill the water.
Now, we only wish it will last one whole summer. Will update!We had one of those &#34;Just flip and place a purified water bottle for humidity&#34; as shown on TV product last summer. It did not even last 2 days worth of day time travel before the water leak started for no reason.
I find that when I am in the car for extended periods of time in the cold, dry weather, particularly when it is severely cold, I start to feel it. This works great. I can feel the difference withing an half hour. It holds about a a cup of water, which doesn't sound like much. But when you consider how small the space in a car is, it is more than sufficient.
Great for in the office or in the car especially in these nasty north east winters. Helps to make a long commute a bit more manageable!
Answer: Not really sure. I usually use the intermittant setting. I drive about 40 minutes each way to work 5 days a week, and it lasts a month or so that way.
