Is it quiet when in operation?

It's difficult to give an honest assessment since mine only lasted 2 weeks. Sorry.

It functions quietly. The only bad thing about this is that it has to be refilled e 2 in 24hrs

It does make some noise while operating but, it is not loud to me. This is my second Panasonic and I like them very much. When this ones quits working, I plan on buying another.

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.

Yes it is. It has moments when the condenser may run and you might hear a slight noise, but by and large, this is a very quiet unit.

It's very quiet, just a slight hum. I don't even notice it. I've had mine for several weeks! Quite satisfied !

It is quiet. Don't buy if you plan on using it on surfaces other than a table or desk.

It is very quiet! You can hear it but a white noise, not problematic at all.

It's pretty quiet with the fan running. It's virtually silent with the fan turned off.

Very quiet. The only time you will hear it is when it clicks on or clicks off.

Yes, it is quiet. It is installed in one of our motel rooms and is so quiet when I walk in I have to look at the panel to see if it is on.

As I said in my review, it is WHISPER QUIET! I was very surprised. Hope this helps.

I do not think it is very noisey. In fact I have opened it up to see if it was working because it is so quiet.

No, it's super quiet. No one would know what you were doing. The only noise it makes is a soft suction noise, but only you and maybe the person next to you would be able to hear it.

It's makes the sound of perhaps "light air flow." I don't think it will disturb anyone. It's not completely silent but the sound is "soft."

Unit is quiet. No fan noise is noticable. We have been satisfied with its performance to date. Have had for about 4 months

The one I purchased and installed is relatively quiet. I don't notice any noise. I'm happy with the purchase.
