Comfort Zone Ultrasonic Turn Bottle into into Personal Portable Humidifier - 6 Hour Operation - Whisper Quiet, Travel, white (CZHD20)

I have two of these to add humidity for my small group of orchid plants. I discovered that the unit will quit working if the base becomes overfilled with water; so, be careful not to jiggle it or it will burp and overfill. I also found that efficiency was lost after a while and, although I use distilled water, it helped to remove the lid on the base and wipe away the scuzzy film with q-tips.Later notes: I am now happily using three of these for my orchid plants. I've discovered the secret to getting excellent humidifying> As I put the 'plug' into the filled bottle I depress the plunger to release any internal pressure built up as I tighten the plug into place. Hope this makes sense because I am now getting great humidity for fussy orchid plants. Also, I use distilled water only and have to rarely clean scuzz from the devices.

At first, I loved this humidifier. We use it when we are traveling. The first weekend we used it, it was great. However, I just used it over Thanksgiving and the second night there (fourth total night we have used it), it started spouting water all over, like a fountain. I thought it was a problem with the bottle connection, so I got a different bottle. It seemed to be working, so I used it that night. It ended up not working properly, and actually left water damage on my grandma`s dresser. I honestly wish this was not the case, as it was AMAZING when I first got it.I considered ordering another one to see if it was a fluke. Yet, I don't really want to spend the money twice...

Why did you pick this product vs others?:Small space needed a small unit, always on control made it more functional.

Original review - Can't get it to keep running. Runs very intermittently.Update. I figured out you need to use tap water, or at least bottled spring water. The outage sensor relies on electrical conduction, and bottled water that is distilled water with added minerals for taste does not conduct enough. Once I started using plain tap water it started working fine. The down side to that is that over time you will get the minerals in the water settling out and coating things.

I should have known buying a cheap portable humidifier was a waste of money! I got it today and was pleasantly surprised by the unit. It was better made than my last one, it had a rubber tapered top to fit any size water bottle opening, which I loved, and the electric cord wasn't some thin cord. As soon as I set it up I knew it was too good to be true. The unit leaked all over my counter and even at full blast it did not release a decent flow of mist. I'm saddened because the casing and overall design are awesome, but unfortunately it cannot do its job. Unless my unit was seriously defective, I can barely give it a one-star. I'm too leery to return for a replacement, so I'll have to choose a different model.

This is a very weak personal humidifier. On the maximum setting, it will process a bottle of water in 12-16 hours which is clearly an indication that it simply is not putting out much humidity. The output port is also very small which is in line with the amount of humidity being discharged. The adapter that is put in the water bottle to connect it to the device is a bit awkward and can easily leak when putting a full bottle on the device.It does have a blue LED indicating that it is running and a red LED to indicate that it has run out of water.There are other devices for more money which can put out considerably more humidity and will process a bottle of water in 6-8 hours when on the maximum setting. Spend more and get a better device.

I love this humidifier. It is very easy to travel with and keeps my skin from drying out. You can use different sized bottles to fill the tank. I usually use a large bottle and it will last beyond 8 hours of sleep. Highly recommend!

It's ok. It's worth the money. A water bottle is too heavy to stand alone. I have to prop it up so it is not top heavy. Also the dial is in the back so it is awkward to adjust with out turning the whole thing around, because you have to be easy but to have the water bottle fall off and spill. After working fir a while it starts and then turns off and on over and over again. Although it does do the job, great out put of midst.
