Panasonic WhisperValue Ceiling/Wall Mount Bathroom Exhaust Fan, 50-80-100 CFM, FV-0510VS1

Easy install, runs very quietly, does a great job sucking out the moisture out of the room from showers. Wish it was a little noisier to help conceal “bathroom noises” but better than being too noisy I suppose!

It’s so quiet wow pretty good! I got one for each bathroom

I built a plenum in the wall for this fan, 2x4wall, needed a thin fan to fit, mounted in a room for my kitties litter box’s.

This is a great fan and moves air very well with less noise than common fans that have a name starting with "B". A UL Listed fan was an absolute requirement. Lots of low profile fans on the market that do not have a safety certification. However, Panasonic is missing out on ceiling-side installation as a replacement fan. I was able to remove the fan and the section that holds the duct/electrical junction box from the housing. It would have been possible to reconnect the duct/electrical section once the housing was inserted from the ceiling side.....but the attachment point was misaligned by the thickness of the drywall, so I had to install from the attic side anyway. If the housing was 5/8" higher to offset the drywall thickness, the unit would still fit a 3-1/2" low profile space, but would be installed through the ceiling side rather than on the attic side. One review states they were able to install from the ceiling side, but the version I received would not work this way. Also, it would be better to provide a way to secure the fan housing from inside the room rather than the attic. The support arm provided is a challenge to install in tight spaces in an attic. I realize this would require retooling at the factory, but I would have selected a UL Listed low-profile fan that installed on the ceiling side over any others - if it was available. This one works nicely, but could be easier to install with some design changes.

Nice easy install

The Panasonic FV-0510VS1 is an excellent choice for anyone seeking a quiet and energy-efficient bathroom ventilation fan. Its WhisperValue technology ensures minimal noise, making it perfect for bathrooms located near bedrooms or other quiet areas. The low-profile design allows for easy installation in standard 2x4 ceilings, although I recommend using a 4-inch vent hose for optimal performance. The fan's Energy Star certification guarantees efficient operation, helping to reduce energy consumption and lower utility bills. Overall, the Panasonic FV-0510VS1 is a reliable and high-quality ventilation fan that provides both quiet performance and energy savings.

This is my first fan I've installed, so I didn't know what to expect, but I'm super happy. I put it vertical in the wall of a small-scale server closet in a bedroom to vent into the adjacent hallway (silly? yes. Awesome? Also yes). It says it can't be installed with the output facing down but I think that's because the 4 side mounting holes are keyhole shaped one way. There are two on the "bottom" opposite the output that seem adequate. It's working fine after I installed a fire break to hold the bulk of the weight. I'd be shocked if the bearings or whatever wore out as it's "upside down." Some are complaining that there's no stencil included. This thing seems to be designed to be placed BEFORE drywall which is unfortunate. It's a 10 inch opening but a 12 inch flange with the mounting holes that need to go into the STUDS directly, not through drywall. I placed it within an already built wall and just cut up some cardboard and sealed it into the seam. I supposed you could use.. you know.. duct tape. I also removed the screwed on support rail and tossed it. It's probably fine... UPDATE: I can't believe it's been 18 mo. This server closet gets a bit toasty and I have it on a thermostat. I'd say this thing is running about 70% of the time. It's been silent and working well this whole time. Vertical mounted and overused and still working!

Panasonic makes the quietest bathroom fans. I've installed three of them in two houses and been happy with each one. I can hardly hear them but if you stand next to the door in bare feet, you can feel the air coming in. This low profile model fit where a standard size fan would not because of a wood beam running over the fan hole. It has a slow start, which I'm not crazy about. I don't see why you would need that. A switch to turn that 'feature' off/on would be better than only having a slow start option. This one is in a half bath used by guests and for those that don't know its the switch for a fan with a delayed start, they think the switch just does nothing. Anyway, when you want a fan that doesn't sound like a 747 taking off, choose a Panasonic Whisper.

Easy to install. DC motor. 3 speeds selectable: 50 cfm silent, 80 cfm semi-silent, 100 cfm noticeable sound of whooshing air but very localized to fan area ( motor is silent, whooshing air makes noise). Yes as per instructions it takes a few (5) seconds for fan to turn on after flipping switch. We run it to vent basement at 100cfm and it even pulls air from first floor down our staircase. In conjunction with a dehumidifier and this fan, our basement is more comfortable as the dehumidifier pulls cool damp air from floor level and blows warm air (from heat-exchanger and fan motor) upwards and this exhaust fan takes it outside. We have replaced all builder installed fans with similar DC motor ones within this price range. Would buy this for bath fan replace so it can be run at full speed to remove heat in house during summer and at a low speed in winter. CON: exhaust pipe is oval and adapter not available in Canada: work around: use 4 inch aluminium elbow: tape seams of elbow with metal tape (or else joints will come apart) and then gently squeeze one end until it matches oval shape, insert and tape together to fan.

The 70 sq.ft. bathroom in our house had a 70 CFM Broan installed which was quite loud, but more worrying was the amount of moisture on the ceiling and running down the walls after a shower. Bought this one based on the reviews and the selectable CFM’s. It installed fairly easy since it all comes apart, just had to cut a bigger hole attach the duct and wiring, snap it back together and screw it to the joist with some extra wood support I installed for rigidity. I set it at 80 CFM and its much quieter than the previous fan which was 4 sones. More importantly there is no more moisture collecting on the ceiling and walls!

Due to the nature of my ceilings in my bathroom, a ceiling mounted vent fan was not an option. So I planned on wall mounting a ceiling fan but couldn't find anything that would fit in a 4" wall cavity. My friend who owns a contracting company told me about this fan and how it has a smaller profile. I have to say it fit perfectly with no hassle at all. The availability to select 50, 80, or 100 CFMs is a great feature given that there aren't many low profile vent fans out there. The noise levels at 50 and 80 are very quiet. However, at 100 as you can imagine it gets a little louder. My wife and I actually decided to set it to 100 CFM because 50 and 80 were too quiet. The noise of the fan offers some... "privacy" when using the bathroom. Thankfully, to change the CFM is extremely easy, simply remove the cover and flick a switch. The general install was straightforward, particularly if you are handy. A few screws secure it to the stud, wiring is as basic as it gets, and the cover leaves lots of room for error when drywalling around it. My only slight concern would be the shape of the duct. I used zip-ties along with aluminum duct tape as you have to bend the ducting to fit the low profile oval shape. I understand that this feature must exist to fit the 4" space, so I can't complain too much. Overall, if you require a vent fan that can be used in tight spaces, this is a great option.

Excellent product. I have bought 5 of these in the past few years and they are all great, quiet and well built. I highly recommend them.

It’s not totally quiet, i can hear it but it’s not loud. It works well, was easy to install. It takes time to start when you push the button (maybe 5-10 seconds) but it works well
