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

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.

Excellent bathroom fan. Very quiet while still moving plenty of air. The build quality feels solid, and the SmartFlow technology keeps airflow consistent. The speed selector is a nice feature and makes installation more flexible. Easy to install and a noticeable upgrade from standard noisy fans. Definitely worth the price for the performance and reliability.

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's easy to install with the Flex-Z Fast bracket. I could do it without access from attic. The noise level at 110 rpm is just normal compared with my old fan. I would not say it's quiet. There's also a delay in starting. It struggles to start at the beginning. I thought there's something wrong with it. But many people said it's normal for this fan. It's effective to draw humid air from the shower.
