What are the sound ratings for the unit- in sones or dB? How quiet is the fan relative to other window fans?

Eco Breeze is definitely in the quiet category of window fans. It is easy to have a conversation while Eco Breeze is running.

Not sure on a rating but it is very quiet. For a while I had squealing problems on the exhaust blower like something was rubbing and I would use silicone spray on it. I was going to try and take it apart and fix it but all of a sudden it stopped making the noise.

I'm happy with mine. It's actually fairly quiet for a gas fired backup generator. If you vent the exhaust away from your house, it helps. I really have no idea of the db level.

For me if I put it two meters away and set it to lowest level, I can nearly heard any noise. But the sound of fans at the highest and middle level are quite clearly to be heard, which you may enjoy. The highest level is loud. Hope this will be of help.

It is somewhat louder than the single fan in my new Mac Pro, which is almost inaudible. It's really pretty quiet, although I have no way to measure the actual decibel output. I do hear the hard drives within when they spin up, and also when they are accessing data. I am not bothered by the "noise" at all.

I think it is 1.5 sones. We purchased 3 within one year and all were very quiet.

Dont have a dBa rating, but it is loud, similar to a running fan like 24 " in dia.

I don't think it's loud at all. I've had it running 24/7 in my bedroom since I got it and it's pretty quiet. It's about the same noise as a window a/c or quieter. Hope that helps!

The product description says 0.5 sones. My description is it's really, really quiet ... So quiet that you have to be careful not to forget to turn it off.

I'd classify it as quiet on low fan speed, moderate on high. I have no problem sleeping with the unit in the bedroom on low, or on watching TV in the same room, etc. On high, it's pretty noticeable in the same room, but inaudible elsewhere in the house.

One other thought. If there is a Lowes or Home Depot near you with demonstration fans, run one with a similar Sone rating and then you can get a feel for how loud it will be. Best of luck. Stephen

10 CFM probably will not make a lot of difference. 1 Sone is a significant difference in the level of noise. I think the quietest fans are rated at 2 sons, and 6 is extremely loud and the highest that it gets. The scale is just from 2 to 6. One sone difference on this scale is significant. I think it definitely worth it. I upgraded one bathroom fan, the noise reduction was huge. Now I am ordering another one for the laundry room.

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

It is pretty darn quiet, I've never measured, but it isn't noticeable if it is running or not most of the time. I've got one in my shop and I hear a window unit from 2 rooms (masonary walls) over it.

I use mine in a shop, I would say the noise level would be similar to that of a box fan. The unit does a great job.

Quite noisy - we moved it to the basement from the living room. I can't compare to a window AC but it is noisier than a central air. Although it is the proper size for our house, it ran continuously to achieve a 45% humidity for our house.

don't know about "sone" sound measurement...my unit is as noisy as a small 6 inch fan...i.e., not very noisy

Haven't had any problems with ours,,, right in our bedroom, very quiet. You might try checking to make sure it is installed securely, and not rattling on the window frame. Also check to be sure no packing material has fallen into where the fan is located.
