I need the CFM and decibel (noise) ratings on this fan. These are my two most crucial criteria, but no one shows them

Dont know the CFM, but the fan is fairly quiet. Keeps the master bedroom ventilated at night without keeping me awake. Sorry not more details.

I can't answer that in the way you're asking, but I will tell you the moise is not offensive at all.I have the fan in the TV room and I have not had to raise the volumn at all. And if you read my pevious note on this fan i will correct my brain lapse and say exhaust and in take at the same time.Hope this helps.

The reason I replaced by 20 year old fans was poor performance and/or extreme noise. These were definitely an improvement, but I cannot say I can detect the higher CFM performance. Easy to install though.

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

"Very loud"? I owned two of these after trying out three different brands/models in the last five years, and both were average noise level of a desktop computer fan. I would say if the noise you're hearing resembles something louder than a desktop computer running, then some thing is up. Good luck!

My inline Panasonic 30NLF1 exhaust fan is extremely low noise. I have to strain to hear it. I should have added a small light to show when it is on.Buy the highest CFM you can afford.

I measured it at 70 decibels running at full power. I consider it noisy in general, but not for an AC unit.

Mine works well, fans are very loud. They sent me replacements haven't installed yet...

Dude, That's a representation of the size differences. One fan should be listed. lol

Wow, that's a tough question. I have the fan mounted on a radiator on my little airplane. I actually do not hear it run as I'm flying with a headset on. I do know that when I run it while the plane is in my hangar, it really is rather quiet running. I'd have to guess that a db rating would be in the low range. perhaps 40 or so.

Neither the box nor the fan itself doesn't state what the CFM is. However, it will keep you cool while you're sleeping if you don't have power. I wish I had them (I bought 2) when we lost power two weekends last year.

It lists as 12.5 but I have since put an additional 45 CFM computer fan next to it and the Valterra fan blows almost 3 times as hard as the comp fan. I think they got the measurement wrong.

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.

The fan doesn't make much noise. Depending on the temperature setting, the fan makes a low "quite" hum.

The fan is very quiet. I almost did not buy this because someone wrote a negative review on the fan noise. This is not an issue at all.

I'm not sure of the actual "rated" CFM, but they Cool WAY better and are MUCH Quieter than these fans:www.summitracing.com/parts/flx-320/overview/
