It is completely silent and there is a dial on the bottom to turn the light off.

It is truly silent. I don't think you want to turn the light off because that's what neutralizes the particles. It is a blue light, but if you need it totally dark in the room to sleep then move it. This unit really works. I have own it for almost 2 years and bought one for a friend and he swears by it. I'm thinking about getting a second one because I spend the night in two seperate places in a week.

It is absolutely silent. I am not sure it is worth the cost. I have had it for 2 weeks and haven't noticed much difference.

There are two settings only - bright and dim - it can not be turned off. You would not be able to read the display if it were completely dark.

not loud at all. I hardly hear it. It is connected with the light, so if you want light on you also have the filter on. Have to unplug to turn off filter and of course then no light.

You can leave the light turned off... but it does not come with any way of covering the light or installing the fan without the light.

I have not noticed any sound. It is so comfortable and completely blocks the light.

It doesn't hum or make noise. It's bright enough to read by, it definitely doesn't light up a room. It just has an on/off switch. It's pretty light weight.

Doubt it. My guess is it can be turned out to be fairly quiet. Another thing to consider is that the light is not very bright at all.

Not at all, it's almost completely silent... You'll just hear a slight hissing with this one

It's completely silent when turned off. The tv is close to silent when on other than the buzzing.

No. You can dim it but when you turn it off and back on it comes back to full brightness.

No, it is silent. The Infrared bulbs turn a little red when the pic is taken but there is no sound.

Yes, you can turn the light off. The unit will still diffuse without it being on.

No, it is not completely silent. The unit is like a very low hum. And, I have found I need to stay within 10 feet to smell the essential oils, so I do hear the sound.

We have this in our living room on a shelf and when it is on utility power, it is silent. The only time you hear it is when it is running due to utility power loss.

It's actually so quiet I forget it's on and don't turn it off before leaving the room. Extremely quiet.

It is silent, it don't have built in flash though, you would have to use your existing lighting
