How Efficient are Panasonic Bathroom Fans?


Panasonic’s exhaust fans use premium ECM (electrically commutated motor) motors, which consume less energy yet produce more air.

Four pole AC and DC motors make up these fan motors. Since they have four poles, they operate more smoothly and efficiently than regular bathroom fans.

And naturally, this leads to higher energy efficiency and quieter exhaust fans that use a lot less energy over the course of a year.


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


There is a straightforward calculation you can do to determine the cost to operate your Panasonic fan over the course of a year.

Find out the bathroom ventilation fan’s wattage first. The WhisperFitEZ, for instance, uses roughly 25 watts. As a point of reference, the earlier Broan 671 bathroom fan consumes 250 watts, which is ten times more energy.

A conversion of 25 watts to kWh yields a daily energy use of 0.6 kWh. It uses 219 kWh in a year (365 days multiplied by 0.6 kWh).

In the USA, a kilowatt hour costs on average roughly 12 cents. Thus, 219 kWh times $0.12 equals $26.

In essence, you will spend about $26 if you use your WhisperFitEZ constantly for an entire year, and by no means would the majority of homes leave their fan on constantly.

What Is SmartFlow Technology?


Since Panasonic motors are ECM, they may instantly change their speed to achieve the desired CFM.

Bathroom fans, especially Panasonic vent fans with SmartFlow technology, will turn on automatically when they detect static pressure. Therefore, if your duct system has a few twists, you won’t have to worry about not reaching your desired CFM because the fan will automatically increase its speed.


How Quiet Are Panasonic Bathroom Exhaust Fans?


The majority of Panasonic bathroom fans have a sound rating of 1.0 sone or less, which indicates that they are extremely quiet.

Additionally, Panasonic enjoys using bigger blower wheels because they can flow more air at faster RPMs while producing less noise. In general, a smaller blower wheel will move less air (at a lower RPM) and make a lot more noise.

On the market, Panasonic offers some of the quietest bathroom fans.




Ventilation fan noise is measured in sones. In general, the bathroom vent fan is quieter the lower the sones. I would consider anything rated as 1.0 sone or less to be very quiet. Most homes have a bathroom fan that is very noisy and in the 4.0 sone range.

Noise Complaints


To be honest, one of the most common complaints in the market is from homeowners about noisy bathroom fans, and Panasonic fans aren’t exempt. Unfortunately, noise levels can also be increased by things other than fans.

Panasonic tests the noise levels of their exhaust fans in optimum conditions. Therefore, if you have a 3-inch duct instead of the 4-inch duct that Panasonic employs and advises using, your noise will be louder due to the higher resistance.

Additionally, since the vent duct could not even be connected inside the wall, you shouldn’t presume that the bathroom fan is truly sucking air out of the building. By turning on the fan and observing air flow at the outer cover, you can confirm air flow.

Additionally, noise levels might rise with each duct turn and length of the run. The amount of noise will increase if your duct is 30 feet long and has three 90-degree turns.

The most crucial aspect of achieving the specified Panasonic sone rating is matching the recommended duct size, which is often either 4-inch or 6-inch.


What is a Panasonic


If put properly, Panasonic bathroom vent fans are premium exhaust fans made to get rid of moisture and unpleasant aromas from your bathroom.

Panasonic offers a variety of sizes and features for their exhaust fans.

The majority of the CFM (the measurement of fan speed) falls between 50 and 110 cfm. I advise purchasing a fan whose speed is at least 50 cfm. Here is a link to my comprehensive article on bathroom fan sizing.
