No one wants a noisy bathroom exhaust fan. If anything, the majority of complaints we usually see about bathroom fans concern noise. Some people have gone as far as replacing their quietest bathroom exhaust fans because of noise.
The good news is that there are hundreds of extremely quiet bathroom exhaust fan models. We’ll review a couple of them shortly. If you can pick the right one, you’ll never complain about noise issues throughout the fan’s life.
However, the bad news is that finding the right quietest bathroom fan isn’t as straightforward as you’d think. Why? Because although the whisper-quiet operation is one of the primary considerations when shopping for a bathroom fan, it isn’t the only factor.
Additionally, something could go wrong during the life of the silent bathroom exhaust fan. When that happens, even a quiet fan can become noisy.
So, what’s the solution?
I believe in a two-prong approach. First, you need to invest in a silent bathroom fan you can afford (keeping in mind other factors). Secondly, you must know how to diagnose and even fix fundamental bathroom exhaust fan noise issues.
Bathroom Exhaust Fan Sones
Perhaps we should begin by understanding how powerful exhaust fan noise is measured. Generally, exhaust fan noise is measured in “phons,” a unit of measurement created by the American National Standards Institute (ANSI).
“Phons” measures the level of loudness of the noise. However, for most home appliances, including quietest bathroom exhaust fans, the sound level is rated based on a “sone.”
These two, i.e., “phons” and the “sone system,” are related. Forty phons equals one sone. The two are also related to the more familiar decibel (dB) measurement. By definition, one (phon) = 1 decibel at 1000Hz (1 kHz) = 40 sones.
It’s essential to keep the frequency in mind. A sound with a higher frequency, such a grating sound, will have a higher sone than decibel value.
What’s a “Quiet” Exhaust Fan?
Now that we understand what “sones” means in noise measurement, it wouldn’t be too difficult to determine a range in which the bathroom fan would be considered quiet or noisy.
First off, it’s important to mention that the standard quiet bathroom exhaust fan produces 4 sones of noise. Any exhaust fan rated under four sones is considered very quiet while those above four sones would be categorized as not very quiet.
Secondly, bathroom fans are rated anywhere from 0.3 sones to 7.5 sones. It’s unlikely that you’ll find a model rated lower than 0.1 sones. At that sound level, the best quiet bathroom exhaust fan barely produces any sound.
On the other side of the scale, values above 7.5 sones are also not very common. Indeed, you should stay away from quiet bathroom exhaust fans rated over 7.5 sones.
Finally, perhaps a few comparisons will give you a clue of the sound levels represented by the various sone rating.
- One (1) sone is about the sound of rustling leaves
- Two (2) sones is the sound of a quiet refrigerator
- Three (3) sones is the sound of a silent office
- Four (4) sones is the sound of the television
- Seven (7) sones is the sound of a normal conversation
- Nine (9) sones is the sound of a noisy restaurant
As you can see from the comparison, anything lower than 4 sones would be ideal for a silent bathroom exhaust fan.
It Starts with Choosing a Quiet Bath Fan
The first step to a noise-free fan operation in the bathroom is selecting the best quiet bathroom exhaust fan. The following are a few considerations to help you pick out the right fan.
Always choose a fan rated below 4 sones. If you must select a 4-sone+ quietest bathroom exhaust fan, it should be an irresistible exhaust fan with strong abilities in other areas. As we’ve already mentioned, even a few quiet bathroom exhaust fans are rated under 0.5 sones, with some as quiet as 0.3 sones. Anything below 2 sones is good enough for bathroom use.
There are a few people who don’t mind low noise levels. Indeed, some even desire a bit of white noise. For such people, a 3/4 sone exhaust fan would be ideal.
The ability to move air, measured in Cubic Feet per Minute (CFM), will also determine the fan’s level of noise. 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.
This is another crucial factor. Some of the quietest bathroom fans are also the most energy-efficient. But, that’s not always the case. In some cases, the manufacturer may sacrifice energy efficiency for silent operation or vice versa.
You don’t want to compromise energy efficiency for quietness. It’s counterproductive to enjoy less noise in the bathroom while spending more on energy bills, right? Instead, try to balance the two. The exhaust fan must score highly in both departments.
Cost vs. Noise
Usually, you have to pay more to get a quieter bathroom exhaust fan. The opposite is also true – you can choose to spend less but accept to deal with a more noisy model — a significant dilemma.
The best solution here is to buy the best exhaust fan – within your budget. Fortunately, some best quiet bathroom exhaust fans are very affordable. Even among the quiet models, a few are priced under $100. With your budget in mind, identify and compare the products in that range and pick one with the lowest noise rating.
Finally, you must read customer reviews before you make the final decision. Why? Because the manufacturer doesn’t always tell the truth. These people want to sell their existing exhaust fan as quickly as possible. So, they must say all the positive things about the products. Some of the attractive features are usually exaggerated.
Reading reviews (at least a few) will tell you what people already used the fan in real life. Do they agree with the manufacturer? Did they find the fan quiet? If so, then that must be a good quietest bathroom exhaust fan.
When an Initially Quiet Fan Becomes Noisy
It’s also possible for the noiseless bathroom exhaust fan you bought and installed a few weeks to make a few noises. When that happens, there could be two problems – blockage or damage/breakage.
Cleaning a Blocked fan
Often, when your exhaust fan is making lots of noise, the motor could be dirty. Or, it could be a dusty fan or crud. It should be relatively easy to blow out the dirt using a blower. Alternatively, use a hand vacuum. The vacuum will also remove any debris.
When you’re done, start the exhaust fan again and see if there’s change. If the noise hasn’t gone away, there’s likely to be a bigger underlying problem.
Repair/Replace a Broken Motor.
A lot could go wrong inside the fan system. Some of the wires may be damaged, and it could be a short circuit, the motor may break down – the list is endless.
You can always attempt to repair the unit or buy a new fan– or call an HVAC professional to take a look at it. But repair comes with one major downside, i.e., finding replacement parts. Not many hardware stores stock these parts. Moreover, if you hire a professional, the cost would exceed the price of a new fan by the time you’re done.
For the above reasons, if a very powerful exhaust fan you’ve been using starts making unfamiliar noises and you’ve tried blowing and vacuum cleaning it in vain, the more straightforward solution is to replace it. The good news is that quiet bathroom exhaust fans are easy to replace. Better still, you can take the opportunity to bring in a quieter replacement.
Installing a Bathroom Fan for Quiet Operation
For the best outcome, we recommend that you call in a professional to do the installation. That’s because even a small mistake during the installation process can contribute to bathroom fan noise. Just one missing screw can create a rattling sound that you won’t like.
If you decide to install it yourself anyway, begin by reading through the user guide. Then proceed as follows;
- Pick the installation location: The guide usually suggests a few ideal spots. Mark the area and ensure that it fits the fan, leaving enough space on the sides. Also, ensure that the surrounding wall/material is strong enough to hold the grill.
- Drill the pilot hole: Start by drilling a small hole with a hand drill. Then use a hole saw to make the exterior wall hole bigger.
- Install the exhaust fan: All you have to do is follow the instructions in the user guide. The hanger and screws should be in the package. Make sure that the power cord stays over the motor fan for easy access during electrical wiring. Once everything is in place, tighten the exhaust fan using the screws then put the grille in place.
