Panasonic FV-0510VS1 Whispervalue Dc Fan

The Panasonic WhisperValue Exhaust Fan FV-0510VS1 is incredibly quiet—you barely notice it’s running. It moves air well and feels like a big step up in quality compared to typical fans. It really helped elevate the overall feel of our bathroom remodel. Solid, reliable, and absolutely worth it.

What a big improvement over the cheap fans of years past. Really quiet and does the job. This is our third bathroom install for these fans. It’s always best to find a YouTube video as the directions are a bit confusing. This fan was made to fit in a 2 x 4 wall thus the oval exhaust hole. Instead of spending $20 for the premade adapters which may not fit, buy a galvanized 4” x 3” reducer and gently oval the 4” side with your hands. Use tape for galvanized or aluminum to secure it to the neck on the fan.

I like it being extra quiet.

This seems like a very good fan, being powerful and easy to install. It would be very quiet except that there's an annoying rattling sound as if a thin piece of plastic is somehow flapping around somewhere inside in the unit. It's not coming from the ductwork but somewhere inside the sealed fan assembly. I don't know if all units are like this or if I got a lemon, but I'm too lazy to uninstall it and send it back for an exchange. However, it might just annoy me enough over time to prompt me to take it apart. The other weird thing is that it's impossible to find matching ductwork (elbow or converter) for the oval-shaped exhaust duct. You would think this would be a fairly common product. I found a plastic one at Lowe's (also on Amazon), but the oval shaped is too different to fit. In the end, I had to bend some aluminum flex duct to couple it to standard 4 inch round ducting.

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!

Have two, one in each bathroom. Work great, adjustable fan speed and not noisy. Cover removes easily for cleaning as I vacuum the cover and every few months same for dust from the fan, our home has a lot so just to keep it well maintained.

The fan was larger than the one it replaced but not hard to open up ceiling to fit. Looks cleaner than the old one but it takes a few minutes to get up to full speed.

Amazing bathroom fan. Buy this. I have ZERO steam on my bathroom mirror. I learned to go bigger than what’s required. The only issue that someone might run into is the oval duct. But if you have the flexible duct tubing it’s fine. I use a large zip tie and aluminum tape for extra protection.

After having to do more monkeying with drywall then I like enlarging a hole overhead with the requisite detritus in my eyeballs I finally got to squeeze the bejeezus out of very old 4" pipe and got this fan in. I had to take it all apart to sleeve the smaller housing with the opening and the electrical portion in place, pop in a couple screws, suture up the melding of the pipes with foil tape and snap in the larger housing, replace the fan guts with three screws and plug in tge electrical quick connect.. I only have it affixed on two sides but seems solid. I omitted the internal flap on this unit as it seemed to significantly reduce air flow and the exit duct already has a flap. On 50 setting in a 45 sq ft bathroom there is sufficient airflow and no discernible noise. Pretty great.

This fan more than met my expectations. It is amazingly quiet, very well built, and easy to install. The ability to adjust the discharge rate with the flick of a switch is a real bonus, and the "shallow" design made it easy to install into a 4inch stud set-up. Highly recommended!

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.

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!

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.
