PanasonicWhisperFit Retrofit Ceiling Mount Bathroom Exhaust Fan, 50-80-110 CFM, FV-0511VF1

I have done seven ventilation fan replacements between my previous house and current house using the Panasonic fans. Builder-grade ventilation fans just did not cut it - they were loud and useless. Of the seven Panasonic fans used five are previous model FV-08-11VF5 (other than using AC motor and having just 80/110 CFM selections, it is identical to the FV-0511VF1 under review). Two are FV-0511VF1. They are all excellent ventilation fans, probably the best retrofit option for the home owners due to their easy and innovative installation method. Especially if the access to the space above ceiling is limited.FV-0511VF1 uses DC motor and it takes about a minute to reach its full speed, unlike the previous AC motor model which reaches full speed in less than 10 seconds. Once reaches the full speed I can feel the air flowing and it is pretty quiet (especially compared to the builder-grade fans I replaced). One thing to keep in mind, even though this fan comes with a 4"-to-3" duct adapter, I recommend using 4" duct whenever possible to get the best performance and the lowest noise level out of the fan. Of the seven replacements I have done, I was able to replace six original 3" ducts with 4" ducts through attic space. I was not able to replace the downstairs bathroom one as its duct goes through floor and ceiling space that I have no access to. And this one definitely has less performance and higher noise level than the other six.

We completed a long-awaited bathroom remodel for our main bathroom. We had a contractor do the majority of the work. The fan, we replaced on our own. We had to cut the hole-slightly larger, than the hole that the old fan was removed from. The installation went well. The directions are straight forward and easy to follow. We saved some money doing it ourselves. This is a nice fan...the quietest we have taken notice of. It moves air and with two shower heads running, the mirrors stay free of fog/steam. We were not interested in a light option, blue tooth speaker, gold stencil, fuzzy dice, or any other option...just a simple bathroom exhaust fan that does what it is spec'd to do. This fan certainly does a great job. We will be purchasing the same model for the other bathrooms in our home.

Panasonic Bath Exhaust Fan – Quiet, Powerful, and Amazingly Easy to InstallI've installed over a dozen Panasonic bath exhaust fans, and every single time, the reaction from my customers is the same: pure amazement. These fans are incredibly quiet and impressively effective — a true upgrade from the typical noisy, underperforming units.Panasonic has clearly put a lot of thought into making these ideal for replacement installs. Even for the average DIYer or handyman, the process is straightforward. Yes, you’ll likely need to adjust the electrical setup and cut a slightly larger opening in the drywall, but Panasonic makes it easy. They include a cutting template, all the necessary screws, and clear instructions. Each install has taken me about an hour — and just this month, I’ve done three!Now, let’s talk about the noise — or rather, the lack of it. On the lowest setting, you might not even realize it’s running. Medium speed gives off a soft, pleasant hum. And even on high, it’s just a gentle white noise in the background. No rattling, no whining — just smooth, quiet airflow.These fans clear out moisture and odors in no time. I honestly can’t emphasize enough how effective they are. If you're looking for a reliable, whisper-quiet, and easy-to-install bath fan, Panasonic is the way to go.
