Breezi AC water tank, how often do you actually empty it?

I dump mine every night. Leaving standing water in something that sits on a desk just seems like asking for slime after a few days. The tank pops off without much fuss, rinsing it takes a minute.

I don’t dump mine daily and it’s been fine for weeks, though I use it sporadically rather than all day. My bigger issue is remembering to refill it at all, since the cooling fades fast once the water runs low. Rinsing is easy enough, the tank lifts straight up, but I don’t bother unless I can see something in it. Do you find the cooling drops off noticeably after a few hours?

Refilling while skipping the dump is a habit I recognize. Since the tank lifts out anyway, I dump whatever is left right before refilling, so it is one motion instead of a separate chore. The mist draining it faster actually makes that easier, since I am emptying it more regularly now. Leaving old water to sit for days is the part I would not keep doing.

The tank coming off is the easy part, rinsing it takes two seconds. My gripe is the design assumption that you’re dumping it constantly. A little leftover water sitting in a plastic reservoir in a warm room is basically a petri dish with a fan attached. I’ve seen enough travel mugs go funky after a weekend to know better. If I ran one of these daily, I’d be emptying it after every session, not because the manual says so but because I don’t want to be breathing whatever’s growing in there by Thursday. The real question is whether the cooling is even worth the daily chore compared to just having a fan on my desk, which requires zero maintenance and doesn’t get slimy.

Mine gets a quick rinse every few days, that’s about it.

The tank pops off fine, no tools or twisting needed. Rinsing is the part I skip half the time and it’s still been fine after a few months. I just dump whatever’s left in the sink before it sits overnight, takes like five seconds.

I left water sitting in mine for about three days once and the smell when I opened it was enough to make me gag. Not mold or anything fuzzy, just that gross stale water smell that sticks to the plastic. Took two rinses with warm water and a bit of dish soap to get rid of it. Since then I empty it at the end of whatever day I use it, no exceptions. The tank itself comes off without any fuss, one little tab and it slides right out, so emptying is maybe ten seconds of effort. Rinsing takes a bit longer because of the corners, but it is not a hassle. I get that people with light use can get away with leaving it, but after that smell I am not risking it again. For the price of these things I would rather spend the extra minute than deal with that funk drifting into my face while I am trying to work.

Dumping it daily sounds like more effort than it’s worth for a little desk cooler. I usually just tip whatever’s left into a plant and let the tank air out overnight, which keeps things from getting funky without a full wash every time.

Leaving a little water in there overnight isn’t going to kill you. I’ve gone days without dumping mine and it was still usable, just a bit stale smelling. The tank comes off without any fuss though, that part’s fine.
