Does it last without refilling the water for about 12 hours consecutive?

It will last app. 12 hours on a tank, the nice feature of this cooler is that when it starts getting a little low you can use the built in timer, from 1 to 4 hours. This thing is worth the money.

It will definitely last 12 hours, no problem, and there are two settings, less or more water flow.

No. The water shuts off when there is enough in the tank. It only refills when needed.

For me has lasted all night, I haven't let it run more that 8 hours, but it's lasted at least until then. The water was about 1/4 full after that time, so I'm assuming it can run close to 10 hours.

Not too slow. Have no problem with refill time. 5 minutes or so it you are empty. Water tastes great.

Hi Deborah! I found your question worthy of further investigation. Although I was pretty certain mine had run longer than 4 hours, I thought I would pay better attention today. lol I filled it to the max and it ran for 7 hours. (I may have lost track of the last hour. As the water level decreases, the mist isn't quite as "thick".) In any case, it ran longer than 4 hours. I am very pleased with the performance of this little room diffuser. Regards, Ms. Wit

I ordered this model just this past November. We use it almost everyday in my office at work. We start it about 8:30 AM and it goes throughout the day until 5:00 without a refill. There is typically still water in it when it is turned off at the end of the work day. I would say at least 10 hours, if not more! This is the best one I have had after returning several to Puritan's Pride!

Yes, continuous until the water runs out. I can recommend this as OK, but the older models were better designed. This was the best of the price range I found and I am happy with it.

It holds 1.2 gallons. I assume the 80 hours is for the lowest and coolest setting. At full blast, it lasts 24 hours. I haven't seen any white dust or uptick in my electric bill (since there aren't any filters to replace), but I think any product like this only works as well as the water you put into it. Our tap water is fairly neutral (not too hard or soft).

It steams about two hours ,it's run out before without damage but wouldn't recommend doing that. It is not a large steamer and needs to be refilled way more than once daily.

My will last 20 hours every day I use this. That's how often I use My last for 20 hours each time I use this. Only I use distiller water. I really do like this unit.

Yes, it does work continuously without any interruption to cool, but I have never used it more than an hour continuously, just to take a good care of it...

Yes. Our use is minimal - probably a couple gallons a day on average. When the system triggers the refill, it only takes a very short time. Once tank is full, it just sits there - no additional water waste.

My granddaughter uses it ... She ran it for two nights, and she said she didn't have to refill it.

Well basically it depends on the use. Im using it non stop and it lasts 1 hour maybe a little bit more.

Mine usually runs for 10-12 before I refill it. It's going to depend on the level of saturation you put it to.

As long as the water lasts. I've had it on for a 3 hour class I teach and it has not run out. Longer than that, I don't know. You can always just add more water. I love it!

Not that I've observed thus far and I use it 1x per day. It starts when you plug it in and stops when you unplug it. The instructions say to not let it run out of water to pump though so you do have to watch it once your water is getting shallow. Hope this helps!
