WhisperChoice AutoPick-A-Flow 80/110 CFM Ceiling Bathroom Exhaust Fan with Motion/Humidity Sense and Flex-Z Fast Bracket

Difficult to install in my case but amazing once installed. Very quiet and it sucks a lot of air. Get the one with the motion/humidity sensor. It is worth it.

The installation of this fan was fairly easy! Even a one armed man can do it (my left arm was broken recently, and I have limited use of it)! After removing the old fan, a larger hole had to be cut, a simple task with a keyhole saw. The fan utilizes a mounting frame, which makes the job much easier. Use two screws to attach the frame to the rafter/joist, then extend the other side of the frame to contact the next rafter/joist, and use two more screws to attach it there.. Next, you snap the fan body into the frame and secure it with another pair of metal screws. All that's left to do is connect the sensor to the fan cover, insert the power plug into the receptacle, and then compress the retaining springs and push them up into the slots of the fan body. The final step is to push the cover up flush to the ceiling. We are using only the timer function, which is an excellent feature. We maxed out the humidity sensor, so the fan won't turn on due to muggy conditions (this is installed in a half bath, NOT a full bath with a shower). We leave the wall switch ON all the time, so the fan will turn on automatically when someone enters the room, and then shuts itself off "x" minutes later, after the person leaves the room ("x" is the timer setting .. we chose 10 minutes). It is a great fan, and it is very quiet, while being extremely effective at exhausting the bathroom air.

We recently replaced 3 fans fir this ones. It is perfect. No foggy bathroom anymore. It turned on automatictly once you step in to the bathroom. Very poverfull fan. Not noisy like others. You cannot even notice sometimes its on or off. Highly reccomend

I love these fans and have installed two, but the design does not accommodate what my house has which is two layers of ceiling drywall, totaling 1-1/4 inches of ceiling drywall. The most the standard installation of this fan can accommodate is just under an inch (see the photo), so I have to carve a layer of drywall to accomodate the bottom flange. I mark around the edge of the flange and use a razor knife/box-cutter to carve-out just one of the two layers. As the old fans are mounted next to joists, there is probably a fastener in that space, so it's good to use a finder to locate it before you start cutting. It all adds to the mess of enlarging the hole from the old fan. This is a pain, but otherwise, the fan is quiet and moves air very well. Gee, it would be great if Panasonic designed the fan with a bit more clearance so that such field modifications were not required where two sheets of 5/8 inch drywall make-up the ceiling. What do you think Panasonic?

Super quiet. Grill has clean lines and is pretty slim. Motion sensor works great. The output duct is fairly high on the side of the unit, which makes routing ducting easier over studs. Paid a bit more than some of the cheaper units, but once you start cutting holes in your ceiling and investing in ducting, it is more critical the base unit is good for the long run.

Just got this installed. Newly remodeled bathroom. Super quiet. It does have a 2 second delay whenever I turned the switch on. Unable to get an answer from Panasonic if this is normal. Only used it a couple of times. Hoping it will continue to work well and last a long time. My contractor did not say anything about installation. So I guess it’s not difficult if you know what your are doing.

Great fan. You need a proper fan for controlling condensation and moisture, much better then cheap builder grade fans. I bought specifically for the humidity sensor functionality. If you hardwire it “on” (Ie constant power) then it could just operate by itself via sensors. However, we used a typical fan switch so it has a manual override. I.e. the sensors won’t turn the fan on because there’s no power to the unit. With the fan switch on then it will operate if 1) humidity sensor triggers or 2) motion detector triggers. I would have preferred it if the humidity sensor could trigger at any time and there was a manual on/off but I didn’t see that in any unit. I have used these fans for both my own residence, and commercial rental properties. Extremely quiet, but robust and effective. Installation is relatively simple. Took me a while at one place with plaster ceiling but the fan went in No problem. The plaster repairs took hours. With typical drywall no issue. Definitely recommend.

Really quiet, easy to install, nice bathroom exhaust.The only drawback is motion sensor is very sensitive and if you keep your bathroom door open, the fan will kick on just by walking by. I read about that elsewhere (there was nothing about that in the manual) and tried it myself. It worked; all you have to do is to angle the sensor a little bit outwards from walking area to stop this issue. You may be able to see that in my pictures attached.

Great product, easy to install and very quiet! Love It! We installed 2 of them!

Easy to install and once turned on it was so quiet I had to hold a piece of paper up to the grill to make sure it was running. This is the first exhaust fan that I have installed that was actually whisper quiet. Excellent product.
