Perfect Aire Personal Travel Humidifier - Ultrasonic Cool Mist Using a Standard (12-24 oz.) Water Bottle with Auto Shut-Off , Great for Travel, Best for Small Spaces at Home, Office, and Hotels

I had a co-worker tell me about humidifiers that used water bottles and I was like, wow, I need to check that out! I researched several models on Amazon and read lots of reviews. I am happy with my choice on this model. When it first came, I had a really hard time pushing the adaptor into the top of the water bottle and was afraid that I didn't have the right kind of water bottle. I was using a 16.9 oz water bottle. After pushing with all of my strength straight down on the adaptor, it fit snug into the bottle. After that first time of struggle, I had no further issues and am able to push the adaptor in with less pressure.The reviews are right that if you set the dial past the half way point, it will last only 6-8 hours, maybe less depending on how high you turn it. The first night, I think I had the dial just shy of 3/4 of the way to the fullest setting. I would say it lasted only 6-7 hours. The next night, I set the dial closer to half way and it lasted closer to 8-9 hours. I feel that at half way or just a pinch past on the dial offers sufficient mist. It also will last a little longer if you use a 20 oz water bottle as well.I was so please with the first purchase, that I actually purchased another unit about a week later. After using that one for about 2 or 3 nights, it suddenly stopped working. Had no power. I used the plug from my other unit and it worked, so I knew I had a faulty plug. I called the customer service number for Perfect Aire and within a few moments of conversation, the customer service rep was telling me they would send out a new plug. I received it in the mail in a few days. Very satisfied with their customer service.Whether you plan to use this unit for home, work, or travel, I would definitely recommend it. And yes, the unit does turn off when the water is empty and the indicator light on the front is a bit bright at night. I placed a piece of electrical tape over it and problem solved.

Piece of junk. Seemed to work fine initially, but after 5 or 6 uses, it suddenly stopped working and all the water began leaking out.

Ordered it and took it to Las Vegas for a week. Solid performance and for me it was a game changer. Woke up without a dry nose/throat every morning. Now a few pointers: When you select a water bottle to go with this don't get an ultra cheap bottle that crumbles easily. A water bottle that is made of better plastic will work way better when you insert the plastic adapter/valve. Another observation is that if you use it on a night stand next to... Keep the dial on its lowest setting so your water bottle lasts longer before needing to refill it.

Ordered for trips, because dry hotel air from the heaters makes us congested and sleep bad. Replacing a old unit that wore out, different brand no longer available. Got this a bit late, when it did arrive, set up was pretty much like our old one, using a bottle of water for the source. This units problem is the bottle connection doesn't screw directly to the bottle like our old one did. This has a push in piece with a o-ring seal that you shove into the bottles opening, THEN a threaded adapter that screws on to that, that has the water stop valve in it. Problem is, the piece that you are supposed to stuff into the bottles opening, is very snug, causing you to grip the plastic bottle tightly while inserting the piece, and you end up squeezing the bottle to hard squirting water out. If you put the water valve on the bottle adapter first, it creates a total air block, and you can't push the bottle neck adapter in because of back pressure. You end up having to pour out or drink some of the water, to get this two piece adapter into the bottle. Not a huge thing, but, our old one just screwed directly on the bottles threads and went right in with no spilling or squirting water.Operation wise, this works as any ultrasonic humidifier, and puts out a good amount of vapor, that comes out the little (separate piece) directional nozzle. Only set up one day, and all worked okay after the messy water bottle thing, so can't speak to longevity yet. I imagine it will last a good amount of time for what it is. For travel it's a great thing to have. This unit didn't have a carry case, or bag like our last model did either, I'll find something to put all the parts in for our travels. That's my take on the humidifier.

Have ordered several times to give to friends and family.

This personal humidifier is the talk of my office. While small, it does the trick admirably. I no longer suffer from static and sinuses issues at the office. A couple drops of essential peppermint oils and the whole space is improved. Great for clearing the mind, the sinuses and clearing lingering smells from stinky visitors. One bottle lasts all day and the unit is easy to clean so no sediment or mineral build up. I would recommend to anyone.

DO NOT BUY! Unfortunately this worked for less than 5 minutes. During the 5 minutes when it did work the mist did not travel. The fan is very weak and blew the mist less than 6 inches in the air. I had another fan to help blow the mist around but again because the mist barely came out it was pointless. Once it stopped working (I believe because the nozzle was not able to regulate the amount of liquid going into the tank) it never worked again. I tried emptying the tank and starting fresh but was unable to get a mist to come out. Very frustrating. Waste of money!
