My Overall #1 Rated Pick

panasonic whisperfit
  • Flip a switch for 80-cfm or 110-cfm
  • Quiet at 0.3 sone
  • FlexZ Fast install bracket
  • Low profile (good for remodels)

My overall top pick for the best Panasonic bathroom exhaust fan goes to the WhisperFitEZ. This fan has a cool feature where you can flip a switch on the housing (just remove cover) and pick between 80-cfm or 110-cfm. The motor is also highly efficient and quiet at only 0.3 sone. The WhisperFitEZ has a low profile which makes it a good option for remodels, and it includes the FlexZ Fast installation bracket.

How Efficient Are Panasonic Bathroom Fans?

Panasonic uses high quality ECM (electrically commutated motor) motors in their exhaust fans which use less energy but exhaust more air.

These fan motors are four pole AC & DC motors. Since they are four-pole, the motors run smoother and at greater efficiency than conventional bathroom fans.

And of course, this translates to quieter exhaust fans as well as more energy efficiency — they cost far less to run over a year.

What Is The Energy Cost To Run A Panasonic Bathroom Fan?

If you want to determine the cost to run your Panasonic fan over a year, there is a simple calculation which you can make.

First, find out the wattage of the bathroom ventilation fan. For example, the WhisperFitEZ is about 25-watts. And just for comparison, the older Broan 671 bathroom fan uses a whopping 250-watts — it uses 10 times more energy.

If you convert 25-watts to kWh, it comes out to 0.6-kWh energy use per day. Over a whole year, it consumes 219-kWh  (365 days times 0.6-kWh) . 

The average cost for each kilo watt hour in the USA is about 12-cents. So 219-kWh times $0.12 is $26.

Basically, if you run your WhisperFitEZ continuously for an entire year, you will pay around $26. And most homeowners won't keep their fan on continuously by a long shot.

What Is SmartFlow Technology?

Since Panasonic motors are ECM, the motor can adjust its speed on the fly to meet your target CFM.

Especially Panasonic vent fans with SmartFlow technology, the bathroom fan will automatically speed up when it senses static pressure. So if you have a duct run with a few turns, then you don't have to worry about not getting your target CFM because the fan will speed up on its own.

How Quiet Are Panasonic Bathroom Exhaust Fans?

Most Panasonic bathroom fans are 1.0 sone or less, which is a sound rating, and it means they are very quiet.

Panasonic also likes to use larger blower wheels because when it is larger, it can move more air (higher RPM) and with less sound. Basically, the smaller the blower wheel, the less air it will move (lower RPM), and with much more noise.

Panasonic has some of the quietest bathroom fans on the market.


Sound for ventilation fans is rated in sones. I invite you to read my full guide on bathroom fan sones right here.

Basically, the lower the sones, the quieter the bathroom vent fan. Anything that is rated at 1.0 sone or less, I would consider very quiet. The very loud builder grade bathroom fan that is in most homes is in the 4.0 sone range.

Noise Complaints

To be honest, homeowners complaining about noisy bathroom fans is one of the biggest complaints in the industry — and Panasonic fans aren't immune. Unfortunately, there are factors independent of the fan that can increase noise.

When Panasonic tests their exhaust fans for noise, it is under ideal environments. So if Panasonic uses and recommends using a 4-inch duct, but you have a 3-inch duct — then your noise is going to be louder because of the increased resistance.

And you also don't want to assume that the bath fan is actually drawing air out of the house, the vent duct may not even be connected inside the wall. You can verify air flow by turning on the fan and checking for air flow at the exterior cover.

And you can also increase noise for every duct turn and the longer the duct run. If you have three 90-degree turns, and your duct is 30-feet long, this will significantly add noise.

To reach these stated Panasonic sone rating, the most important factor is matching the duct recommendation  — usually either 4-inch or 6-inch.

What Is A Panasonic Bathroom Exhaust Fan?

Panasonic bathroom vent fans are high quality exhaust fans that are designed to remove moisture and foul smells from your bathroom if installed correctly.

Panasonic sells a range of different exhaust fan features and sizes.

Most of the CFM (rating for fan speed) is in the range of 50-cfm and all the way up to 110-cfm. I recommend buying a fan with at least 50-cfm for its speed. You can read my full guide on how to size a bathroom fan here.

What Is Panasonic Corporation?

Panasonic Corporation was founded in 1918 as a lightbulb socket manufacturer in Osaka, Japan.

The company has grown into a multinational leading electronics company making consumer electronics, car and avionic equipment, and residential and construction equipment. Lately, Panasonic has partnered with Tesla to supply battery cells and solar panels.
