Panasonic FV-0511VQ1 WhisperCeiling DC - Bathroom Exhaust Fan with Speed Selector - SmartFlow Technology - Quiet Energy Star-Certified Ceiling Fan - White

It is truly whisper quite! However, the air movement is well beyond the fan it replaced.It takes a few seconds to reach operating speed, you will think it's not on, but when it reaches operating speed, it works great!

It's a bit slow to get going, but is very quiet and moves air well enough for a medium size bathroom. Installation was very easy, partially due to having attic access from above. Still the mounting hardware was a huge step up from the old fan this was replacing.

This thing is relatively expensive for an exhaust fan so you're probably checking reviews to see if it's worth it. From my perspective it definitely is if you want a fan that does a great job drawing out shower moisture and toilet fumes and does so quietly; so quietly that sometimes it's difficult to know when it's running.I bought this model because my cheap-o builder spared all expense and put in a 3" duct. That duct limits the airflow so that the even cheaper fan that they put in could not keep up with the steam from my wife's hot showers so the mirrors fogged up all the time. I was concerned that even with a better fan the 3" duct would still keep the air flow down and it might even make a quiet fan noisy due to the restriction, but my concerns were alleviated with this new fan. I set it on the lowest of the two speeds and it works great in our 8'x9' bathroom! The speed switch is readily accessible if I want to test the higher speed later, but so far I have no need to do so.Installation was not simple, but it was not difficult either. I'm just a homeowner who does most of the repairs and updates to the house, but I'm no professional, yet I was able to get this installed and working within a couple of hours.Bottom line, if you have the coin to spare, you'll be happy with this fan.

The fan comes up to speed gently, so it’s pretty quiet. Impressively so. The snap in air vent is nothing to look at, but what’s important is the amount of air it moves. Our bathroom is large and it really does the job.

I had to listen hard to know it's running :)

Great exhaust fans. Adjustable CFM is nice

It is really a great, quiet fan. I was expecting that I felt more of a draft when in operation. Put the speed switch on highest. Installed the fan with a extra light (when the fan is on the light is on) and a timer switch. Easy to install. With the DC motor it will run efficient and will has a long life.

Update: I bought a second one. It turns on and off repeatedly. I read on someone else's review that this will happen if your timer switch doesn't have the right specs, and they named mine specifically. I'm going to remove it and put in a regular switch to test it out.I installed this in my bathroom because the bathroom fan that came with the house was the cheap builder's-grade fan. It was loud and didn't move much air. After each shower, the mirror was dripping wet and the bathroom was full of steam. After installing this, the bathroom air is clear of steam after a shower. The mirror fogs up, but not nearly as bad as before and it clears really quickly after I get out of the shower. Good choice! Installation wasn't fun because I got up in the attic with all of the blown in insulation so I could install a larger diameter exhaust st run and the fan was difficult to get to in my case. Not the fan's fault. I could have installed it completely from below if I had bigger exhaust piping already hooked up.
