PanasonicFV-0511VF1 WhisperFit DC Fan 50-80-110 CFM Retrofit Bathroom Exhaust Fan - Quiet Energy Star-Certified Energy-Saving Bathroom Ceiling Fan

This is by far one of the best quick upgrades you can do in your house. It is a Saturday project that will be done will before lunch. The plans and template that come with this kit are outstanding. The folding design of the bracket is clever and makes install way easier. The hardest part is removing the old fan. Be ready for insulation to fall on you a little bit. Be sure to have safety glasses on as well as a mask for the dust. Once the bracket and electrical hook up is done, all you really have to do is slide in the fan assembly. It is a snug fit, and it is very satisfying to slide it into place as intended. The brightness of the light is unknown to me because I bought a fan without the light. Be patient once you turn the fan on because once functioning, it is amazingly quiet. However, the power of the fan to clear the moisture out of a bathroom is amazing. The functionality of the fan allows for your mirror to no longer fog up. If you have a noisy bathroom exhaust fan, do not hesitate to do this project. It looks great once it is done, and your bathroom will no longer look like a steam room.

Very quiet even at full CFM. Which is wild because I think it is quieter than my old 50CFM fan that this is replacing.One thing to note the fans do not kick off right away once you turn it on. That is something to get used to.Be careful you check your existing fan measurements above. I had to cut into a non support beam to fit this in because this was deeper than the old one.

Well built, easy to install as advertised, and quiet as it claims in the product specifications. Perfect balance of price, quality, and performance. Great choice for trouble free operation, hopefully for a long time…

The Panasonic WhisperFit DC Fan (FV-0511VF1) lives up to its name — it’s incredibly quiet yet powerful. I installed it in a bathroom that used to get super steamy, and now the air stays fresh and dry without the fan making more than a gentle hum. You honestly have to double-check it's even on!I love the adjustable CFM settings (50/80/110), which give flexibility depending on room size or ventilation needs. The DC motor is energy efficient, and it runs like a dream. Installation was smooth too, especially since it fits into a standard housing and can be retrofitted with minimal hassle.

Overall, excellent product. Very quiet. With 4” venting, it’s very effective at completely eliminating steam and moisture from our 85 sq’ bathroom (tested in our shower with two shower heads running during an intentionally long, hot water shower). Not a trace of fog on the mirror and not a drop of moisture on the walls - the complete opposite of how our old noisy 50 CFM vent performed.I am a very experienced DIYr and did not consider this an “easy” installation, even with complete attic access. My old vent was installed using a 3” vent pipe. I had to replace the entire length of solid and flex pipe to utilize the 4” exhaust vent on the new unit. To me, it made no sense to buy a high capacity unit with a 4” exhaust and then constrict it to 3” via the included reducer. This replacement alone is not possible without attic access.This unit is considerably larger than the one I was replacing. Due to immovable obstructions in the attic (HVAC) I had to install new unit further from the edge of the wall, leaving an old opening to sheetrock, tape, mud, sand and paint.Installation instructions lack clarity concerning two of the most critical steps in the replacement process: connecting the part housing the motor and the part containing the electrical box and vent adapter. I found this confusing but eventually figured it out.Screws: On a minor point, two of the four screw holes on the flange’s perimeter far exceed the head size of the self-taping screws provided. You’ll need to find just the right size washers to compensate for the screw head being too small for the oversized hole provided to secure the other half of the unit.In summary, excellent product, but instructions could be improved and I can’t imagine installing this unit without attic access.
