Whether you’re renovating or just need to swap out a rickety old model, we’ve got the lowdown on the quietest, yet functional options out there.
Get ready to create a calming sanctuary with our ultimate guide to the best quiet bathroom exhaust fans.
When picking a silent exhaust fan bathroom, the level of silence it brings is key. The recommended noise level for a bathroom fan is 0.5 to 1.5 sones.
Sones gauge both the volume and pitch of the sound, and higher sone ratings mean louder fans. Most homes should aim for a fan rating of 1.0 sones or lower, but some homeowners may want to go as low as 0.5 sones for extra peace and quiet.
Here is a table showing the noise level range and the corresponding sones rating:
| Noise Level (dB) | Sones Rating | Description |
|---|---|---|
| 0 – 25 | 0.25 | Barely audible, almost silent |
| 25 – 35 | 0.5 | Very quiet, almost silent |
| 35 – 45 | 1.0 | Quiet, barely noticeable |
| 45 – 55 | 2.0 | Moderate, somewhat noticeable |
| 55 – 65 | 3.0 | Loud, noticeable |
| 65 – 75 | 4.0 | Very loud, annoying |
| 75 – 85 | 5.0 | Extremely loud, very annoying |
| 85+ | 6.0+ | Painful, can cause hearing damage |
does exhaust fan size impact noise level
The size of the exhaust fan affects its noise level. A bigger fan usually has a bigger motor that generates more noise than a smaller fan. But, a larger fan can also have a lower RPM motor that reduces noise.
Moreover, a larger fan may move more air with less noise than a smaller fan since it doesn’t have to work as hard due to less resistance.
Here’s an example table that shows the recommended exhaust fan size and quiet level in decibels (dB) for different bathroom sizes:
| Bathroom Size (square feet) | Recommended Exhaust Fan Size (CFM) | Quiet Level (dB) |
|---|---|---|
| Up to 50 | 50-80 | 0-1.5 sones |
| 50-100 | 80-110 | 0-2 sones |
| 100-150 | 110-150 | 0-3 sones |
| 150-200 | 150-200 | 0-3 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 relies on the room’s size and intended purpose. 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 a 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 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.
conclusion
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 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.
