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

This Panasonic exhaust fan continues the brand’s well-known quiet performance — it runs smoothly with very low noise, which is exactly what I was looking for. The three adjustable airflow settings are a great feature and make it easy to choose the right ventilation level for different situations. For installation, I went up into the attic to get everything properly set up, and the result was excellent. The fan works efficiently, feels solidly built, and delivers consistent airflow. Overall, a reliable and high-quality exhaust fan that I’m very satisfied with. Highly recommended!

Works well and very quiet, but: 1) the exhaust port is only 4", but the cowling is compatible with 6" duct work. So even if you use 6" ducts, there's still a 4" constriction in the airflow. 2) the motor is in a box that connects to a frame. Only the box can be inserted from below. The frame must still be installed from the attic. That's where the power and ducts are connected. So you'll still need to crawl around up there to install this. But, I still gave this fan 5 stars. I'm quite happy with it.

It is really quiet. You don’t even notice it is on. It works perfectly that I don’t see foggy mirror any more. I set it to 100 CFM. It has 50/ 80 option. Had profession to install it. and it took some time but it was not too hard to install per se.

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.

I was surprised by the size although I measured it before the time. I had one concern, the old one was just screwed in place on one side of the beam and then sealed in place with the ceiling finish and this one was bigger and heavier. This concern was gone very quick when I see they included a hanging frame that was adjustable and I could extend it from the current joist to the next one and secure it that way. The whole installation was very quick and well documented (although the font text is small). Set it to max airflow and once all was done, clipped in the face plate, turned on the circuit breaker and flip the switch. Silence.... to only realize it actually has a soft start and running at full speed was so quite you could barely hear it. Checked the flow outside and sure was working great. Way better then the box cutter build engine they had in there. Highly recommend this.
