Our list of the top 10 Best Quiet Bathroom Exhaust Fans with proper ventilation and ceiling mounts has got your back, especially during a relaxing shower.

Whether you’re renovating or just need to swap out a rickety old bath fan model, we’ve got the lowdown on the quietest bathroom fans, yet functional options out there. Check out our buying guide for ceiling mount bath fans.

Get ready to create a calming sanctuary with our ultimate guide to the best low-noise bathroom exhaust fans. Whether you’re looking for a quiet shower fan or a ceiling mount option, we have you covered.

Our recommended fans come with noise-reducing features and are housed in durable materials for long-lasting performance.

When selecting an ultra-quiet exhaust fan for your bathroom, the low noise level it provides is crucial. The ceiling mount design ensures minimal volume.

The recommended noise level for an ultra-quiet bathroom fan with a loudness rating of 0.5 to 1.5 sone is ideal for maintaining a peaceful environment.

Sones gauge both the volume and pitch of the sound, and higher sone ratings mean louder fans. When choosing a fan for your space, keep in mind the loudness factor and consider the cons of having a fan that is too loud.

Additionally, take a look at the different fan options available to find one that suits your preferences and needs.

Most homes should aim for a bathroom fan rating of 1.0 sones or lower, but some homeowners may want to go as low as 0.5 sones for extra peace. Bath fans are commonly installed on the ceiling.

Here is a table showing the range of loudness levels and the corresponding Sones rating for quiet bathroom fans.

Noise Level (dB)Sones RatingDescription
0 – 250.25Barely audible, almost silent
25 – 350.5Very quiet, almost silent
35 – 451.0Quiet, barely noticeable
45 – 552.0Moderate, somewhat noticeable
55 – 653.0Loud, noticeable
65 – 754.0Very loud, annoying
75 – 855.0Extremely loud, very annoying
85+6.0+Painful, can cause hearing damage

The sone is a subjective unit of loudness perception, while the decibel (dB) is an objective measure of sound intensity in various settings, including ceilings, ducts, and bathroom fans.

A loudness rating of 6 sones correlates to approximately 53.83 decibels, making it an ideal choice for a quiet bathroom fan.

To put the loudness rating into perspective, normal conversation at 3 feet averages about 60 dB, while a busy city street can reach 70 dB.

It is important to consider the ceiling for noise levels in different environments, such as periods of quiet bathroom fans.

With a loudness rating of 53.83 dB and a sone level of 6, the bathroom fan may be perceived as intrusive, annoying, or distracting depending on the context.

does exhaust fan size impact noise level

The size of bathroom fans affects their loudness rating. A bigger bathroom fan usually has a bigger motor that generates more noise than a smaller quiet bathroom exhaust fan.

But, a larger quiet bathroom exhaust fan with a lower RPM motor that reduces noise can also be installed in the ceiling.

Moreover, quiet bathroom exhaust fans, such as those with a low loudness rating, may move more air with less noise than louder fans.

This is because the larger fan doesn’t have to work as hard due to less resistance in the ceiling.

Here’s an example table that shows the recommended exhaust fan size and quiet level in decibels (dB) for different bathroom sizes, including the loudness rating and ceiling.

Bathroom Size (square feet)Recommended Exhaust Fan Size (CFM)Quiet Level (dB)
Up to 5050-800-1.5 sones
50-10080-1100-2 sones
100-150110-1500-3 sones
150-200150-2000-3 sones

How to Choose a Quiet Bathroom Exhaust Fan

Determine the required airflow capacity

To choose a hushed bathroom fan, gauge the room’s volume by measuring its length, width, and height in feet, then multiply these figures to find its cubic footage.

Using this data, employ the formula below to determine the necessary airflow capacity: Airflow (CFM) = Volume of Bathroom (cubic feet) x Number of Air Changes per Hour / 60.

The quantity of air changes per hour in a room depends on its size, intended purpose, and the use of quiet bathroom exhaust fans.

Typically, eight air changes per hour suffice for a conventional bathroom, but more may be required for larger spaces or those subject to moisture.

Finally, locate a tranquil exhaust fan that matches this capacity, taking care to balance it against the fan’s noise level and sone rating (usually 1.5 or lower).

Look for a low sone rating

To find a quiet bathroom exhaust fan, seek out a low sone rating. Sone measures a fan’s noise level, with lower scores indicating less sound.

Fans rated at 1.0 sones are hushed, whereas those at 4.0 or higher are boisterous. Bathroom exhaust fans tend to range between 0.5 and 6.0 sones, but a 2.0 or below rating will bring tranquillity.

Additionally, weigh the fan’s airflow capacity, measured in cubic feet per minute (CFM). A fan with a high CFM score clears dampness and smells better, but may also be noisier. Opt for a fan that balances both low sone and CFM for your bathroom’s size.

Choose the right fan size

To select a quiet bathroom exhaust fan, choosing the correct fan size is vital. The fan’s size ought to be based on the bathroom’s dimensions.

To compute the necessary airflow, one can apply a straightforward formula: multiply the bathroom’s length, width, and height to obtain the cubic footage, then divide by 60 to determine the airflow rate in cubic feet per minute (CFM).

Look for insulated ducts

Insulated ducts, wrapped with fibreglass or foam, reduce noise by up to 50% compared to those without insulation.

These ducts also help prevent condensation and heat loss or gain, thus increasing energy efficiency.

Choose a bathroom exhaust fan that uses insulated ducts or can be installed with them to keep your bathroom quiet and energy-efficient.

How do you silence a noisy fan?

Clean the fan

Bathroom exhaust fans get noisy with dirt, dust, and debris buildup, lowering airflow and effectiveness. Clean it to bring back efficiency and quietness. Turn off the power, remove the cover, clean gently with a brush or cloth, and vacuum the remaining debris.

Check the vent cover and ductwork for blockages, and replace them if damaged. Reattach the cover, turn on the power, and enjoy a quieter fan.

Do this yearly for optimal performance. Consider replacing worn blades, installing vibration-dampening mounts, or getting a new fan for even more quietness. An electrician or HVAC technician can provide additional guidance.

Tighten loose parts

Turn off the power, detach the fan cover or grille, and assess the fan blade. If it’s loose, tighten the screw or nut holding it to the motor shaft while holding it still.

Likewise, check the motor mount and the housing for any loose screws or bolts, and adjust the blades to prevent hitting.

Lastly, secure any loose sections of ductwork with metal duct tape or screws. Turn the power back on and test the fan. If it persists, the motor or fan blade may need replacement.

Lubricate the bearings

Bathroom fans remove moisture and odours, but bearings can wear down, causing loud noise. To fix this, turn off the power, find the bearings, and use oil or spray to lubricate them.

Clean them first with a brush or cloth to remove debris. Do not over-lubricate, as this can cause excess oil to drip or more noise.

Test the fan after lubricating. If the noise continues, consider replacing the bearings or the whole fan. By lubricating the bearings, you can extend the fan’s life and make it quieter.

Replace worn bearings

If your bathroom fan makes a racket, chances are the bearings have worn out over time. Replacing them is a cinch for most homeowners with some elbow grease and basic tools. Start by shutting off the fan’s power supply.

Then, detach the cover and motor assembly. Find the bearings on the shaft and extract the old ones with pliers or a wrench. Clean the shaft with a soft cloth or sandpaper to remove rust or debris.

Apply a dollop of motor oil or bearing grease to lubricate the new bearings, ensuring they’re fitted properly.

Use the retaining clips or screws to secure them, without over-tightening. Reassemble the fan, switch the power back on, and test it out. With fresh bearings, your fan will run smoothly and noiselessly for many moons.

Balance the blades

Bathroom fans remove moisture and odour, but imbalanced blades can cause noise. Balancing is easy: turn off the power, remove the cover, check for damage, loosen screws, observe wobbling, and use a balancing kit with weight and instructions.

Attach weight to the opposite blade, observe, and repeat until balanced. Note that older fans may not eliminate noise, and replacement may be more cost-effective.

Install a vibration damper

If the fan is mounted to a flexible surface, it can vibrate and make noise. Install a vibration damper between the fan and the mounting surface. This will absorb the vibrations and reduce the noise.

FAQs for Quietest Bathroom Exhaust Fans

What size exhaust fan is best for a bathroom?

The bathroom’s size determines the ideal exhaust fan size, as per the Home Ventilating Institute. They suggest that the fan should have a minimum capacity of 1 CFM per square foot of bathroom area. So, a 50-square-foot bathroom necessitates a fan with at least 50 CFM capacity. Other variables to consider include ceiling height, number of fixtures, and ductwork configuration. Seeking guidance from an electrician or HVAC contractor is wise.

how do you measure the quietness of a bathroom exhaust fan

Bathroom exhaust fan quietness is gauged in sonar units. Sone denotes loudness or perceived loudness, measured on an American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) scale. Ratings below 0.5 sones mean very quiet, while above 4 sone means loud. A lower sone rating equals less noise.

what is the difference between an extractor fan and an exhaust fan?

Extractor fan or exhaust fan – same, remove air from bathroom or kitchen, suck the air out, blow it out. “Extractor fan” for UK kitchen, takes cooking smells, steam, and grease. “Exhaust fan” for US bathroom, takes moisture, prevents mould. Though the same function, terms differ by region and use.


To ensure comfort, lessen noise pollution, and maintain indoor air quality, it is crucial to find the best quiet bathroom exhaust fan. With numerous options available, one must consider various factors, such as noise level, ventilation rate, energy efficiency, and durability.

Our top picks, which include the Panasonic WhisperCeiling DC Exhaust Fan, Broan-NuTone Flex Bathroom Exhaust Ventilation Fan, and Delta BreezSignature Exhaust Bath Fan With Humidity Sensor, are excellent choices for those seeking high-quality and quiet bathroom exhaust fans.
