What Really is Whisper Quiet Bathroom Exhaust Fan and How Does It Work?

Reliable sources like the Home Ventilating Institute, have rated a minimum of 1.0 sone or less, a quiet exhaust fan. Anything below 1.0 sone will be considered a whisper quiet bathroom fan with less than 0.5 sone been almost silent.

A fan with such a rating will be barely perceptible in a bathroom. You will barely notice its presence in the room. That’s, why having a quiet bathroom fan with LED light, will indicate that the fan is actually working.

Another common trick you can use to know if the fan is working is to put a piece of toilet paper up to the fan to see if there’s suction.

Sone is a sound rating that is used for rating how much noise a product can actually make when operating at its maximum output. Anything from 1.5 to 3.0 sones is considered average loudness and any sone rating from 4.0 above is pretty

So, how does a bathroom exhaust fan work?.  A bathroom exhaust fan works by pulling moisture out of the air before it can cause any harm.

Bathroom exhaust fans are installed in a wall or ceiling to suck warm, muggy air out of the bathroom so fresh air can enter. A properly installed bathroom fan should connect to an insulated metal duct leading directly outside to a roof vent with flashing. The duct should also be straight and as short a possible.

In many older homes, bathroom exhaust fans simply vented the humid air into the attic or the joist space above the bathroom ceiling. This practice is now prohibited under most current building codes.

How to Choose a Quietest Bathroom Fan

Choosing a bathroom fan can be a daunting task especially if you don’t know what to look for when picking one. In case you need help, here are some factors to consider.

Sone Rating

If a quiet bathroom fan is an absolute must for you, then sone rating should be considered because it tells you how much noise the bathroom fan will make. Sone ratings of 1.0 and below are considered quiet and a fan rating of 0.5  and below is ultra-quiet. Most manufacturers usually indicate this figure on the product manual.

Anything below 2 sones is good enough for bathroom use. Always choose a fan rated below 4 sones. If you must select a 4-sone+ unit, it should be an irresistible fan with strong abilities in other areas.

Cubic Feet per Minute (CFM)

CFM stands for cubic feet per minute and it’s the amount of air the fan can move per minute. So the high this number the more air it will be able to move. A larger bathroom will require a fan with a higher CFM rating.

You want just enough CFM power to effectively remove the moisture in your bathroom, but not so much so that it creates noise. To this end, we recommend one (1) CFM per square foot. Therefore, for an 80 square-foot bathroom, you need an 80 CFM fan.

Add 50 CFM for every toilet, another 50 CFM for each shower/bathroom combination, and 100 CFM for every whirlpool.

House Size

It’s also important to consider the size of the bath fan. If you have older 2×4 wall studs, some fans may not fit into the wall. It is important to measure the housing size before you buy the exhaust fan.


The best solution is to buy the best bathroom fan within your budget that is considered quiet. The good thing is that you can get a bathroom exhaust fan that is affordable and quiet but may not have some features that a high-end model will have.

With your budget in mind, identify and compare the products in that range and pick one with the lowest noise rating.

Customer Reviews

Generally, it’s easy to gauge a product quality by looking at what other customers have to say about it. There are a lot of reviews that you can look at especially on Amazon to know what verified customers have to say about the product and rating it.

How to Install a Silent Bathroom Fan

Looking for some tips to help you install your bathroom fan?. Great, these tips will help you to install it.

First and foremost, you will need to remove the existing exhaust fan from the ceiling mount or wall mount, before you can now install a new exhaust fan in the existing cutout.

Most Bathrooms have something called “fast install brackets” which is some type of bracket that exhaust fan can be mounted onto. The bracket gets screwed onto the ceiling/wall framing.

Additional features like light, heater, or humidity sensor would require additional wiring, but if none is present, then the installation will be much easier.

You can just connect the existing wiring in the ceiling to your new fan, and use the same wall switch to turn it on or off.

When it comes to installing a bathroom fan, it can get complex sometimes especially if you have other features on it. This might not be easily installed if you don’t have any handyman expertise. Hence you may need to get a certified person to help you out.

If you can handle it yourself, you will need to connect the wiring to the existing switch and electrical wiring.

In addition, installing a 4″ duct for a quiet bathroom exhaust fan may also require more work such as widening the exterior wall hole, as well as replacing the duct inside the wall or ceiling. According to HomeEnergySaver.Gov — if you have a vent duct that has many twists and turns, it can be just as loud as an older lower-quality bath fan — the vent duct matters.

How to Make a Bathroom Exhaust Fan Quieter

There are many reasons why a bathroom exhaust fan might be making noise.  If your bathroom fan is producing unusual sounds, you can try these techniques to help fix the noise exhaust fan.

Clean the Fan and All Moving Parts

If your fan is making noise, it may be worth giving it a thorough cleaning instead of going out to purchase a new quiet bathroom fan. As dirt and grime build up over the year, it can cause problems for the fan blades.

To clean the blades, first, remove the fan cover so that you can access the fan blades and housing. With a wet rag and some soap water, wipe down the fan blades and the whole fan housing, the motor assembly, and component that looks dirty.

Observe for any damage that may be present and subsequently replace them.

Once everything is dry, replace your fan cover. Test the fan to see if this has alleviated your noise problems. If so, excellent! Your job is done. If not, then proceed down the list.

Absorb the Sound with Sorbothane Rubber

Here is another technique you can use to reduce your bathroom exhaust fan noise. Try using Sorbothane rubber to absorb the sound and vibrations.

Sorbothane is a very soft rubber that is available in easy-to-work-with sheets. It can be purchased with an adhesive backing that makes it simple to apply to your bathroom fan.

Cut the Sorbothane into strips. These can be 1+½” to 2” wide.

Adhere a strip around your fan in line with where the ceiling or wall will be against the unit when installed. This will effectively decouple the fan from the wall, reducing the amount of vibration and sound transferred.

You can also add some of the Sorbothane to the electrical access plate and the fan motor assembly to help dampen some more of the vibrations.

Install a Larger Duct

The larger the size duct you use, the less air pressure is created by the air that the fan is expelling. This equates to less air noise.

Newer fans that are designed to be ultra-quiet usually use 6” duct to help achieve this goal.

If you’re upgrading to a larger duct because you’re upgrading to a quieter fan that requires 6” duct, then all you need to do is replace the existing duct.

If you’re keeping your old fan but upgrading to a larger diameter duct, you will need to get an enlarger coupling that will allow you to use the larger duct with your smaller fan outlet.

Lubricate the Fan Blades and Motor

As your fan ages and with continuous use, the moving parts will dry out and start experiencing increased friction. This will start to cause an amount of wear and tear, thereby reducing the lifespan of your fan.

To check if this is true, remove the fan cover. Make sure the fan is powered off.

First, clean off the fan and the fan housing. Make sure there is no dirt or dust to become thick grime when you add lubrication. This will make your problem worse instead of better.

Now, with lubricant oil, try and lubricate the fan blade. Make to sure spin the blades around a few times while applying the lubricant to ensure that they get a nice coat.

Tighten the Mounting Screws

Another common cause of exhaust fan noise is loose screws. As your fan work for years, the screws and mounting hardware may begin to loosen up. There are two ways to go about tightening the mounting screws depending on how your fan is installed.

If your fan is installed by screws being run through the fan assembly and into a joist, then you may be able to tighten them without getting into the attic. Remove the fan cover. Locate the screws used to install the fan to the joists and tighten them. That’s it, simple!

Many fans are installed to the ceiling joists with hangers that are mounted above the ceiling drywall. In this case, you’ll need to head up to the attic and locate your bathroom fan from above.

Start by tightening all of the screws that mount the fan to the hangers.

Final Thoughts on the Quietest Bathroom Fans

The right quietest bathroom fan can do wonders to your bathroom by helping remove all the moisture in the air after every bath to prevent mold, mildew, and stains on your walls and homes.

All the above are quiet bathroom fans that will work in this regard. The one you will choose will depend on your budget. If you want additional features, then you’ll have to pay more for them.
