how many hours on does the humidifier last
1702717
I use it only at night from bedtime until I get up in the morning, and I use the 30 second "on"/30 second "off" setting. I usually refill it every other night.

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.

I would return it. Mine worked well for about 3 days and started doing it. It hasn't worked since. It seems like a lot of people are having issues with these humidifiers.

During the winter I use my heater all the time and I can fill the bottle that you use to fill the humidifier every other day. I turn the heater off during the day so just running at night not 24 hours. Not sure on the spec but it heats a 400 sq foot basement area for me just fine! I enjoy this heater and had bought one for my mother and then bought this one for myself.

Depends on what setting you have it on and how dry your room is. In my house with forced hot air which is really dry, I get about 24 hours per fill. I believe it is recommended that you fill it everyday with fresh water so expect that at least. I keep it on medium in our room which is 26x16. It does a good job of bringing the humidity up and cleaning the air.

Well Cynthia, When I fill the diffuser to it's max. capacity. Then run it on high with constant on. I get about six hours. I have tried it on the low setting with time out intervals, and it has lasted close to 2 1/2 days..... Hope this helps : ) Keep on Diffusing!!!

run time depends on how strong or week you set the mist at.....i think about 12 hours is max..this is a great little easy to fill humidifier

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

Pretty simple, when it starts to get hard to breathe. Mine lasted about 6-10 hours, but that was with some painting so could last longer with less particulate in air.

Mine has lasted at least a couple of hours. I haven't needed it longer than that.

I've found it lasts all night. Which considering that this is only effective when you are right next to it, and is not intended to humidify an entire room, is all that you would need.

roughly 8 hours on a full tank. You can set a timer function to automatically turn off after a few hours.

Mine lasted for about eight hours of continuous usage. After that it needs about a gallon of water.

We keep ours on pretty high all the time and the water lasts about 18-20 hours. If it was not turned up so high, the water would last longer.

About 3 hours running full time, on/off position about six hours. This is a really good diffuser.

No. The tank capacity does not hold more than 12-15 min. of steam and not designed to work as a room humidifier.

Mine lasts around 3 months. I think this has a lot to do with me living in the desert and the humidity level being very low (less than 15% most of the year).
