        For bathroom installation does this fan need to be ducted to the outside for smell?
        ByOct 8, 2025
        1 Answer | 
        Answer This Question

        Yes, it should be ducted to the exterior, otherwise you are just moving the smell from one place to another. Also, you could create a humidity/condensation (mold) problem by not moving the air correctly.

          What is the maximum length the ducting can be?
          ByOct 4, 2025
          1 Answer | 
          Answer This Question

          As this is an AC motored product it will start to lose performance once ducting exceeds 30". Keep in mind each 90 degree bend adds 5 feet of equivalent duct length.

                  Fan is too weak for small bathroom
                  This is so weak that it didn’t make any difference in removing moisture after showering when using 90 cfm. I still see drops of water all over the walls where the shower does not reach. My bathroom is small, 5x8, not large, and the duct extends horizontally for more than two feet before bending towards the roof. The overall length of the duct is less than 15 ft. This is despite the product seller claiming that 70 cfm can be used with over 60 feet (see their answer to one of the questions). It has been a very terrible experience and now I have to look for another fan from a different brand and install it. I strongly don’t recommend this product.

                    Two bathroom fans installed as replacements 2-yrs. ago. This fan has 2-speed motor setting which is great as the higher setting works best for the larger bathroom. Both motor settings are quiet. I rated 3-stars as the squirrel cage fan is difficult to clean per instructions. The previous fans were easy to remove to soak and clean like new. I purchased this new identical model so I could determine how to remove the fan cage for better cleaning. The entire fan / motor enclosure has to be removed to properly clean out (I do this yearly). I swapped out the entire assembly and installed the fan assembly from the newly purchased complete unit.. After removing and disassembling motor / fan assembly I now have an additional clean unit to swap out. A bit expensive purchasing an entire new unit but this was the only way to determine how to remove the entire motor / fan assemble to throughly clean out. Note - with unit removed you can clean interior of housing in ceiling and visually check vent hose. Photo of fan housing assembly removed and another photo of fan motor. Turn over fan motor and fan cage can be removed for cleaning

                    good for small bathrooms
                    This fan is perfect for a tiny bathroom because it has a 9"x9" footprint that doesn't take up much space. The instructions say it is NOT retrofit friendly, but it was easy to get the sides of the housing screwed into a stud like the instruction, with the bottom flanges going over the top of my drywall. The grill covers everything neatly even if you install over the drywall like i did. I was able to install the whole thing (other than the roof vent) from inside of the bathroom.

                      Ok fan
                      Fan is not to bad! Problem is the springs for cover are so thin and weak it will not pull cover tight to ceiling.

                        NOT WHISPER QUIET!
                        Also not retrofit friendly. I had to take it apart to be able to put it on drywall and had to get up in the attic. This fan is so loud. I really fell for their marketing. I had it on the lower setting. 64db is not a whisper. According to Google, it's the volume of a normal conversation or and AC unit. Now I have to remove it and return it and start all over again. This is false advertising.

                          QUIET and powerful
                          I was looking for a powerful and QUIET fan for above my shower. I take scorching hot showers and because my open plan bathroom has a sloped ceiling the steam travels up toward the peak of the ceiling then out into the bedroom. I wanted a fan that would grab that steam before it made it out into the room. I’m pleased to say this does an excellent job. Having the ability to mount it to the wall was a huge advantage because I didn’t have to open the ceiling which is covered in tongue and groove wood. You will need a 2x6 stud space for installation since minimum installation depth is 4-3/4” The simple cover will blend in with my finished wall and won’t become the first thing you see when entering the room.

                          Not that quiet, mounts poorly
                          Summary: dual speed switch, but not really that quiet, and mounting instructions are wrong and leaves grill unable to latch properly. This basic fan has a switch inside the grill that lets you choose between quieter/slower or louder/faster airflow; you'll probably set it once and never again. It includes three screws for mounting, junction box is attached, and has a standard 4-in. duct fitting. Small footprint makes it a good choice for small rooms or busy ceilings. I disagree with the "whisper" moniker (-1 star): while definitely quieter than the '80's-era fan in my main bathroom, even on low speed I definitely know it's on, not like other "super-quiet" fans I've had in the past. At least it's quiet enough that it doesn't announce to everyone what you're up to :-). The instructions say to mount it directly against a truss/joist, but if you do that you can't push the retainer spring through the hole on that side to hold the cover on; someone didn't think that through (-1 star). Plus, assuming you cut the hole the size of the box so the flanges rest on the sheetrock, you'll have to carve out the sheetrock in the middle where the springs will push through (I did; see pic). Once the grill is spaced away from the face of the fan by a half-inch of sheetrock, the springs don’t hold the cover in as positively; my cover doesn't pull up to the ceiling completely. It'd work better if I mounted it flush with the sheetrock, but then the mounting holes on the side of the box would send the screws into sheetrock, not wood (-1 star). Lastly, once I snugged a hose clamp around the hose on the exit flue, it altered the round of it just enough so that the backdraft flap (which has a lot of gaps) won't fall all the way back down; I'll try loosening it next time I'm up in the attic.

                          Well built and well designed
                          Just installed the Panasonic Whisper Mighty Pick-A-Flow 70/90 CFM Ceiling/Wall Bathroom Exhaust Fan and yes it is extremely quiet at both flow settings. Installation was fairly easy as there is no drywall in the bathroom yet, the housing is held in place with three screws to the ceiling joist and is easily wired with plenty of room in the junction box. The exhaust fan is well made with a sturdy housing and a quality built fan motor that provides a smooth, quiet air flow. The two flows of 70 and 90 CFM are controlled by a switch that is easy to access by lowering the fan grille, but we set it to the higher 90 CFM as this fan is so quiet, why not go with the higher flow? The grille is held in place with two spring clips that will accommodate any ceiling and drywall thickness and makes access to the fan for cleaning it easy. Overall a well built and well designed fan for our bathroom remodel.

                          Selectable airflow
                          This is my review of the Panasonic whisper mighty bathroom fan. This fan has a couple unique features like the pick a flow which allows you to change up from 70 CFM or 90 CFM. This fit my older ceiling fan box and was simple to install. This fan is a lot quieter than our previous fan and seems to do a better job at removing the moisture in the air when I shower. This product definitely lives up to its name.

                          Absolutely Positively Panasonic
                          If you were to ask me for a recommendation for a bathroom fan the first word out of my mouth would be Panasonic. I have used Panasonic fans for over 10 years and have been extremely pleased. The Panasonic fan line up has a ton of options from lights, nite lights and motion detectors. This particular model has a switch that allow you to select between 70 and 90 CFM. I have always found Panasonic fans to run smooth and quiet. The grille is spring loaded to make cleaning easier. Great value in a bathroom vent.
