My unit sounds like a waterfall all the time. It puts out a lot of mist but it's loud. Does this mean it's defective?

Mine is loud too compared with, say, Air-O-Swiss, which I had before, but I've found I can sleep though it. It doesn't sound like a waterfall, though, just like a motor.

It depends on how long you've had it. It might be clogged or need a new filter. If it is new, I think there might be something wrong with it. It shouldn't be that loud.

A waterfall? Check for clogs... It makes a modest amount of noise but I wouldnt say its loud.. Try cleaning it out and if that doesn't work contact Crane.

If you turn it up all the way it can sound like a small outdoor fountain. I turn mine up to where the water hits the base where it starts to expand. I normally don't here anything with it set there.

This sounds like a defect. My unit is very stable and in normal use has been extremely quiet. Maybe yous has been damaged during shipment?

I haven't noticed very much noise on the mister I received. The mist comes out pretty good until the water is running out and then it is off and on, only if I wiggle the container around a little.

You should define what you mean by loud. This unit can rumble depending on the surface it's sitting on and how much water is inside. I think of white noise as something like a hiss, and this unit can sound like that but we had to put a heavy object on top to soften the rumble. You can cover the opening where the filter goes but make sure you don't cover the output vents because that object will get wet from the mist.

Not normal! No motor noise, maybe just a hum. Unless the motor is not stationed firmly and is maybe vibrating, I would return. Mine is so quiet, I sometimes forget it is there until I here running water!

Mine started with a high pitched buzzing noise and now after 4 months the motor is not running right and mist output is low. I am having it replaced as I like the features. If I get one that works and does not make the noise, I will be very happy! :)

Mine isn't silent, but isn't horrible. Sounds like an issue to bring up with manufacturer. They might replace the unit.

I wouldn't say mine gurgles constantly, just occasionally, but I rarely run it on high. When it is on high, it is going to use more water, and sound comes from the valve releasing more water.

Where is it leaking from? Make sure the filter is in place and the water basin is fitting into the base properly. Otherwise, I would return it because it sounds like you have a defective one.

Thanks Wagner. I will set it that way and see if anything changes over the next day or two and post back here.So much for a day or two, I just tried it and it is very loud now. Mine wasnt refurbished, I bought it new in the package. Werid bug for sure.

No, my unit does NOT make such a sound. I DO think it is faulty. Please return it, ASAP, but be sure you tell them why.

I spoke to Watts about this issue. They said the noise is related to water passing through the membrane. I am still looking into it, but the noise is not constant in our case.

Yes I had the same problem and ditched it and found a better humidifier. Our unit leaked from the very same spot. Other people have had the problem. We've had this one for about 6 months: Crane Drop Shape Ultrasonic Cool Mist Humidifier with 2.3 Gallon output per day and it seems to be working well. No filters. It's a little bit of a pain to clean, but a little bleach solution and voila, it's clean. For our needs, this has been a much better humidifier and NO LEAKS!!!!

Yes! Mine also makes the gurgling noise. From my experience, all ultrasonic humidifiers of this size or larger make a gurgling sound. This is due to the gravity fed reservoir gulping air to displace the water being used.

Ha, yeah that sounds right. It was difficult to fix, but what I did was drill two holes in the bottom of the unit towards the back to let the water drain out. It's the fan hitting the standing water that is making all the noise. It's difficult because unless you have access to the unit from outside the house (which I don't), you need to pull the unit out of the window, turn it upside down, and then I drilled 2 holes on the lowest parts the furthest towards the back of the unit. After that... no more noise. Also didn't seem to effect the unit either, still blows cold air.Hope that helped :)- Andy Ha, yeah that sounds right.

I would say that your unit is defective, yes. I used my humidifier all last winter in my office, and never had this problem.
