How quiet or noisy is this unit?

In a word, silent. And I am NOT joking. On the other hand the front panel LEDs are quite obtrusive, but I cover them with electrical tape, and all is good. Why manufacturers insist on having BRIGHT LEDs on their equipment is beyond me. Makes an HTPC setup look rather like an old school arcade game... :-)

I have one of this in my bedroom, I just hear the noise when the device is starting up, after that nothing, I really like it

It likely depends on the drives enclosed, mine sits behind my monitor and is quiet. I can barely hear it when it is writing or reading from the mirrored drives. I used Seagate drives.

I only notice when the hard drives spin up, but after that it's not noisy at all. (Small noises tend to bother me). It probably also depends on how loud the hard drive is.

This unit is fairly quiet. If you are doing audio editing without headphones then I think you might have an issue but otherwise I haven't noticed its volume while I am working.

I think that it is very quiet. I only use it to backup my system and it is not on all of the time. I have not noticed any noise.

You can adjust from low (2500) to high (5000). I do not think the unit is noisy at all. I run it in my business and hardly notice it's on.

We run ours on low & it's in the far corner of the room, so in ours is very quiet. It depends on what speed you run it on & how far you are from it.

Mine is actually very quiet. I had another model that was extremely noisy, so I am very happy with this model.

No really quiet or loud.... If you want power it makes noise, but less than a vacuum cleaner !!!

It's not too loud. Certainly much quieter than some of the larger HP units in our neighborhood.

Not at all - I was frankly surprised at how quiet it actually is. Low hum is about it - even on high. I use it in my basement workshop and don't even notice it after a short time.

It is very quiet. you can barely hear the air flowing through the unit. We have this unit in a den and spend some time there with the kids and we hardly notice that it is on.

Its quiet. I usd it as a bedroom refrigerator, and didnt hear it. Prior, I used it as a freezer, and it was very quiet. Great little appliance.

Unit has three different fan speed settings to help with noise. But my opinion is no, unit is not excessively loud. It is in my bedroom, I sleep with it on low.

In my opinion, yes, it is relatively quiet. At least not as noisy as some others i have used.

The unit isn't super loud or super quiet. But you do hear when it is on. However I have slept with the unit just 2 feet away or less with no problem. The noise level shouldn't be a major concern. If it is than this type of air cleaner is not what you should be looking for to clean your air.

The unit is whisper quiet. If you put it on auto fan, you hardly know the unit is on. The compressor does kick in, but it doesn't blast in and is actually no louder than a window unit.
