Questions & Answers

new fan was installed and it takes 1-2 minutes to start, is this normal?
ByNov 6, 2026
1 Answer | 
Answer This Question

The WhisperGreen Select uses an ECM motor with SmartFlow technology, so some ramp-up as the fan reaches its selected airflow is normal. However, if the fan does not begin operating at all for 1–2 minutes after being switched on, we recommend checking the wiring and any installed Plug ’N Play modules, as optional controls can affect operation. If the delay continues, please contact Panasonic Ventilation Technical Support for additional troubleshooting.

    Does it include a Condensation sensor module?
    ByAug 13, 2026

    Answer This Question

    No, this model does not include a condensation sensor module. However, it is compatible with Panasonic's optional Condensation Sensor Module (FV-CSVK1) or the SmartAction® Motion + Condensation Sensor Module (FV-CMVK3), both of which can be added for automatic moisture control.

      How loud is the fan?
      ByApr 25, 2026
      1 Answer | 
      Answer This Question

      The WhisperGreen Select fan is extremely quiet. Depending on the Pick‑A‑Flow airflow setting, it operates at approximately 0.3 to 0.8 sones. For reference, anything under 1.0 sone is considered very quiet, many users describe this fan as barely noticeable during normal use, especially at the lower CFM settings.

        Does this fan stay on ALL the time. The description seems to say it does.

          No, this specific WhisperGreen Select model does not run continuously on its own. It operates by wall switch unless an optional multi‑speed/continuous‑run module (part # FV‑VS15VK1) is added. If you’re looking for a fan that is designed for continuous ventilation, we recommend Panasonic model # FV‑0511VKS3. This model is built to run continuously at a low, ultra‑quiet airflow to help meet indoor air quality or code requirements, and it can automatically boost to a higher CFM when needed. Continuous‑run fans provide ongoing fresh air while maintaining very low sound levels.

            Can the Model # FV-1115VK3 be used with 4 inch ducting? I know it's compatible with 6 inch ducting. But my roofer wants to taper to 4 inch ducting to use his roof cap.

              The description says: "Smart Action Motion Sensor & Condensation Sensor: Includes advanced sensors for optimal performance, automatically adjusting based on movement and humidity." Are those two sensors are included or are they add-on modules?

              Answer This Question

              Looks like it depends on the model. The cheapest version doesn't include the sensors, but higher priced ones do.

              By|Aug 5, 2025

                The SmartAction Motion Sensor and the Condensation Sensor are included features of this specific model, the Panasonic WhisperGreen Select Pick-A-Flow. They are not add-on modules and come integrated into the fan unit.

                Perfect for our bathroom overhaul. Super quiet and 80 cfm setting works perfectly for our 67 ft2 bathroom. Highly recommend. With DC motor takes about 10 sec to start spinning up which is no problem.

                Quiet fan with 3 speeds
                This fan is very quiet, even on the highest setting. Plus, it moves a lot of air even on a low setting. (There are 3 settings to chose from.) I installed this in the master bathroom but you could even use it in a garage to move air. The installation looked a little intimidating, but it ended up being easy, clear, and straight forward. It helps that the electrical connections were set up to be easy - good for new DIYers.

                Very well made product.
                Packed really well. Comes with a well written instruction sheet. Also, they went further and added a pictured diagram on part of the packaging. That is super helpful. Unfortunately, I chose the wrong size for my bathroom and my ceiling support beams were preventing me from enlarging the space to install this unit. I would double check the size needed and buy the correct size of this product before you buy it. Very well made product.

                Incredible air movement w/minimal noise
                My first impressions were that the quality of the fan and housing were well made and designed. The fan itself is a squirrel cage design (similar to what is in a window or portable AC unit) that moves a lot of air while creating minimal noise. The housing of the fan is made up of two parts, the main part of the housing holds the fan housing and the second part is for the electrical connection and vent piping. The material used to construct both housing pieces is a mixture of painted and galvanized steel and provides a solid base for the fan. The electrical connection is 110vac, fairly straightforward and is similar or common to this type of fixture. The exhaust is 6” but the provided adaptor will neck the size down to 4”. The design of the fan allows for both the electrical and ventilation piping connections to be made prior to install of the main fan box and truly simplifies the connections. The electrical connection of the fan itself is a 6pin unidirectional Molex connector with a positive lock. One note is that the housing of this fan is much bigger than a standard bath fan and requires a 10-7/8” square hole. Movement of air – The fan is capable of switching between 3 fan speeds; 50/80/110 CFM, with and initial factory setting is 80 cfm. Selection is simple and can be completed without the need for tools. I found that the 80cfm setting was the most appropriate; it provided great airflow with minimal noise. The highest setting (110cfm) certainly moved some air without a lot of added noise, but was a bit too much for my application as it caused a windstorm of air coming under the door. Final thoughts – I would certainly recommend this fan and I am pleased with the function and finish. The design of the fan and thought that went into how it would be installed is a near to perfect. The only caution that I would stress is that if the fan is a replacement for an existing fan, the housing requires a larger opening than most conventional fans and the space needed should be accounted for prior to purchase.

                Go For a Quiet Fan!
                The WhisperGreen Select Pick-A-Flow 50/80 or 110 CFM Bathroom Exhaust Fan is a sound choice when upgrading that old, noisy fan in an older home. A “sound” choice in that it is so quiet that you may not know that it is running. Install is straightforward, keep in mind that if you are replacing an old fan you may need to enlarge the opening in your ceiling. The Pick-A-Flow toggle switch is a great feature too, also another feature is the reducer duct to go from 6” diameter to 4” diameter if needed.

                Panasonic Whisper Green select bathroom vent fan
                The Panasonic Whisper Green select bathroom vent fan model FV-0511VK3 is certainly whisper quiet. It’s hard to tell if it’s on. The installation was straightforward, however, this was a replacement for a very old and noise bathroom fan. The instructions were for both new construction and remolding. In both instances the metal support hanger is attached even with the bottom of the ceiling joist. The drywall needs to be cut so the fan housing meets the metal support hanger. Overall, this is a nice looking, simple, whisper quiet fan for a small bathroom. It also has three CFM setting 80, 110 and 130 on the housing under the cover. I recommend this bathroom fan for anyone who prefers peace and quiet while in the bathroom.

                Nice, quiet ventilation fan
                This is a product that lives up to its name. It runs very quietly, and moves a lot of air. However, I can't rate its energy efficiency because I don't have a direct way of measuring it. The installation process was a little messy, partially because it wasn't new construction and I had to crawl up on the rafters to get to the mounting location. The cardboard template that came with it wasn't very useful, so I made my own. Once the mounting rails were secured to the rafters, things came together nicely.

                Panasonic Versatile Exhaust Fan
                Panasonic is known for high quality, quiet exhaust fans. What surprised me were all the add on modules available for this exhaust fan. You can get a multi-speed control, condensation sensor, Wi-Fi control, motion sensor and motion + condensation sensor modules. The fan has a selectable switch for three different CFM settings, 50, 80 and 110. Installation was very easy. It took more time to get the old fan out of the ceiling. The mounting bracket folds to easily get it through the opening, then expands to secure it to the joists with screws that are provided. The side of the fan box that has the electric connection box and exhaust is removed and installed first to make connections easier. I used the included reducer because I have 4" duct pipe. This fan is quiet and very good at preventing condensation.

                Whisper quiet
                Panasonic has always been at the top when it comes to exhaust venting. The whisper quiet series has a nice selection of speeds accessible after the install from the white cover plate. The bracket attaches to most truss spans with its slide design. The exhaust has the option of 4” or 6” with the supplied adaptor. I would recommend using an insulated tubing from the exhuast fan out of the vent.

                Adjustable cfm Ceiling Exhaust Fan
                Purchase this fan as our current fan, I think is as old as our house, it was shipped very quickly and arrived perfectly. Its a good size, cover is 13 inches square. It also has adjustable cfm, from 50, 80 or 110. We are remodeling our bathroom and this will be a great addition to pull the steam from taking a shower. Very well made and comes with everything needed for installation, even the mounting braket. I also love that if the cfm you set it on is to strong, just need to pop off the cover and turn it down, or vice versa.
