how much water does it hold? and how long can it run until it needs a refill?

It holds exactly one gallon of water. One gallon will last between 2 and 5 depending on how much mist you use. To relieve the heat of a hot day, expect 2 hours before a refill.

It holds 1 gallon. How long it lasts depends on the setting. A setting of somewhere between 1/4 and 1/2 will give you about 2 to 3 hours. However, a setting of close to full will cut that back to 1 or less.

Holds about a gallon. Runs about an hour before needs refilling. Adjustable mist level. Sight glass on back shows water level.

It holds a gallon, but the time depends on your mist selection. I use it full blast in AZ so it's about an hour for me.

800ml fills it to overflowing. Realistic capacity (with enough room for the stopper/lid) is about 650ml or 21.5 oz.

It will run for a while after using it, as it is in fact refilling the holding tank. It should stop after a while though. Depends on how much water you used, but it does seem to take a while to refill.

I've let it go 2-3 days without it running completely out of water (1 cat), but usually add about a quart every other day. It holds more than it appears to.

This item has a detachable reservoir in the back that is filled with water. It holds enough to make quite a few cups without refilling.

1/2 gallons.. i believe. it holds a lot. Goes all night 8+ hours, on high, without refill

When I refill it each night (and it does need refilled each night or it will be empty before morning) I typically put 4.5 gallons in it.

It holds a little bit over One gallon and it runs for over 8 hours on a full tank at 50% load. I ran it daily on a recent camping trip. We used it for running the microwave and getting the evening news and the initial fill up lasted a week.

I am not sure of the maximum time as I only run it about 30 minutes at a time. I have not had to refill the water very often. Sorry I cannot answer your question.

Surprisingly it holds a lot of water. Depends on how many people are using it but we are 3 and only need to fill and empty it every 2 to 3 days

I use a small pail and water from my rain barrow or tap. I usually refill about once a week using the size pail I have. Works great

Sorry. I never tried to refill it. I have only used up one of them and I just threw it away.

When we run it constantly I added water every day just to get the water up to the "full" line, but I never let it go empty so I can't give you an exact length of time for that. If you ran it just off and on for either cooling or to humidify the air you wouldn't have to add it as often. It is very easy to fill.

The steam stays on until you've run out of water. I haven't timed it but it is a reasonable amount of time. When you refill it is only a matter of seconds before you can continue.

I noticed that mine won't work if its low on water, so make sure it has the recommended amount. It seems after an hour of use it needs refilling.

No, I refill every couple of days - also necessary to keep water fresh. Theoretically, it could run dry if left for a very long time without adding water.

probably almost a cup...i usually get 30 mins at least of usage before it runs out.
