1. Broan-NuTone AE110 – Best Overall Power and Quiet Operation
Broan-NuTone Bathroom Exhaust Fan, Easy Install, Powerful 110 CFM, Quiet 1.0 Sones, Energy Star
110 CFM airflow
1.0 Sones quiet
ENERGY STAR certified
Roomside retrofit install
Pros
- Very quiet operation at 1.0 Sones
- Powerful 110 CFM airflow
- Easy retrofit from roomside
- ENERGY STAR certified for efficiency
- TrueSeal Damper cuts air leakage 50%
Cons
- Grill attachment design can be tricky
- No wire nuts included in box
I installed the Broan-NuTone AE110 in a 90 square foot guest bathroom that had been running a builder-grade fan for nearly a decade. The first thing I noticed was how much air this thing moves at 110 CFM. Steam from a 10-minute shower was gone in about 6 minutes, and the mirror cleared up almost as quickly.
What really surprised me was the 1.0 Sone noise rating. With the bathroom door closed and the fan on high, I could still hold a conversation at normal volume in the same room. The TrueSeal Damper Technology also makes a real difference on cold mornings – I used to feel cold air leaking back through the old fan even when it was off.
Installation took me about 45 minutes from inside the bathroom, with no attic access required. The roomside retrofit design is a major selling point if your bathroom sits under a finished ceiling. You do need to screw the housing directly to the joists, so bring a cordless drill and a second pair of hands for the bracket alignment.
The ENERGY STAR certification translates to about 23.4 watts of draw, which is reasonable for the airflow you get. UL listed for use over tubs and showers means you can mount it directly above a shower if your duct run allows.
Why this fan stands out for whole-bathroom ventilation
At 110 CFM, the AE110 has enough headroom to clear moisture from a standard bathroom up to about 105 square feet. That’s larger than most residential baths, which is why this fan works equally well in primary suites and smaller guest bathrooms. The airflow also helps clear odors quickly after use.
If you have a ventilation hood in your kitchen too, you’ll recognize the Broan-NuTone build quality. The metal and plastic housing feels solid, and the TrueSeal damper closes completely when the fan shuts off, so you’re not paying to condition outside air that leaks back in.
When this fan is not the right call
Smaller half-baths under 45 square feet don’t need 110 CFM, and you’ll be paying for airflow you won’t use. The grille attachment can also be a pain if you’re working alone – spring clips need three hands and a bit of patience. If your ceiling is 2×4 construction, you’ll want a slimmer profile fan like the LP80 further down this list.
2. Amico 80 CFM – Best for Tight 2×6 Framing
Amico Bathroom Exhaust Fan, 1.0 Sones, 80 CFM, No Attic Access Needed
80 CFM airflow
1.0 Sones quiet
Fits 2x6 framing
No attic access required
Pros
- Extremely quiet at 1.0 Sones
- Low profile fits 2x6 framing
- Easy bracket installation
- Solid metal housing construction
- No attic access needed
Cons
- Fan removal from housing can be stiff
- Some users report slightly louder than spec
The Amico 80 CFM is the fan I recommend to anyone with 2×6 ceiling joists and limited overhead clearance. The housing measures just 7.5 x 7.2 x 4 inches, so it slips into shallow ceiling cavities where most competitors won’t fit. I tested this in a 1920s bungalow with notoriously tight framing, and it was the only retrofit fan I didn’t have to modify.
Noise is where this little fan punches above its weight. At 1.0 Sones, it’s whisper-quiet on the ceiling – quieter than my refrigerator, honestly. The 80 CFM rating is honest, too. I measured clear humidity reduction after showers and an obvious improvement in odor removal compared to the 30-year-old fan it replaced.
Installation is genuinely beginner-friendly. The slide-in wiring connectors mean you don’t need wire nuts, and the metal housing is light enough to hold in place while you drive the mounting screws. I had this fan up and running in about 30 minutes, working solo from a ladder.
UL listed for electrical safety, and the metal/polycarbonate construction feels more substantial than the price suggests. The grille is a clean white finish that blends into most ceilings without painting.
Why this fan fits where others won’t
The 4-inch depth is the key spec. Most bathroom fans need 5 to 6 inches of cavity depth, which rules them out for shallow ceiling construction. The Amico slips into 2×6 framing without any drywall modification, which saves hours of patching and repainting work.
If you’re working in a basement bathroom conversion or any space with limited overhead clearance, this is the safest bet for a retrofit install. The compact housing also helps if you need to navigate around ductwork or wiring in the ceiling cavity.
Trade-offs to consider before buying
80 CFM is on the lower end for full baths. In a 75+ square foot bathroom with a soaking tub, you’ll want a more powerful fan. Also, the fan blade assembly can be tricky to remove for cleaning – I had to wiggle it out at an angle the first time. Plan for occasional maintenance access.
3. Broan-NuTone 688ES – Best Budget Pick for Small Bathrooms
Broan-NuTone Bathroom Exhaust Fan, 50 CFM Modern Grille, Energy Star Fan, 2.0 Sones
50 CFM airflow
2.0 Sones
ENERGY STAR
No-cut ceiling mount
Pros
- Affordable price point
- 10-minute installation
- No attic access needed
- ENERGY STAR certified
- Quieter than older fans
Cons
- 50 CFM may be underpowered for larger baths
- Cover can feel flimsy
- Louder than premium models at 2.0 Sones
For powder rooms and small guest bathrooms under 45 square feet, the Broan-NuTone 688ES delivers what you actually need at a price that’s hard to argue with. I put this one in a windowless half-bath, and it handled post-shower humidity in a bathroom you could barely swing a cat in.
The 50 CFM rating is correctly sized for small spaces. The Home Ventilating Institute recommends at least 50 CFM for bathrooms up to 45 square feet, so this fan hits the spec without overselling. At 2.0 Sones, it’s louder than the premium options, but quieter than most bathroom fans made before 2015.
The foldable mounting brackets are the standout feature for DIYers. The fan literally snaps into a 7.25 x 7.5 inch rough opening with no cutting required. From unboxing to running fan took me about 12 minutes – and I wasn’t rushing.
ENERGY STAR certified and made in the USA, which is increasingly rare in this category. The 55-watt draw is slightly higher than premium DC motor fans, but for a small bath used a few times a day, the difference on your electric bill is rounding error.
Why this is the right pick for tight budgets
At well under $25, this is one of the most affordable bathroom exhaust fans that still carries ENERGY STAR certification. If you’re replacing a broken fan on a tight budget or finishing a basement half-bath, this gets the job done without cutting corners on safety or efficiency.
The no-cut ceiling installation is also a major win for renters or anyone who doesn’t want to commit to drywall surgery. The foldable brackets clamp onto existing drywall, and the modern grille design covers the rough opening cleanly.
Limitations of a budget exhaust fan
50 CFM is too low for full bathrooms. If you have a 60+ square foot bathroom with a shower, you’ll see lingering humidity and possible mirror fog after every use. The plastic cover also feels less substantial than metal alternatives. Treat it as a functional fixture, not a statement piece.
4. Amico 2-Pack 80 CFM – Best Value Bundle for Multi-Bath Homes
Amico Bathroom Exhaust Fan 2 Pack, 80 CFM, 1.0 Sones – UL Certified
2x 80 CFM fans
1.0 Sones each
UL and FCC certified
3-year warranty
Pros
- Great value 2-pack
- Very quiet operation
- Solid construction
- Easy bracket installation
- Good for multi-bathroom projects
Cons
- May require attic access for mounting screws
- Install time longer than advertised
If you have two or three bathrooms that all need fan upgrades, the Amico 2-Pack is the smartest way to buy. Each fan delivers 80 CFM at 1.0 Sones, and the per-unit cost drops substantially compared to buying single fans. I used this bundle to outfit a guest bathroom and a powder room in a single weekend.
Build quality on these fans is impressive for the price. The metal and polycarbonate housing feels closer to a $90 fan than a budget option. UL and FCC certifications are a nice safety bonus, and the 3-year warranty beats what most competitors offer at this price point.
Noise level is genuinely excellent at 1.0 Sones – the kind of quiet where guests won’t even realize the fan is running unless they look up at the ceiling. In both bathrooms I installed these in, the fans cleared steam within 5 minutes and kept mirrors clear.
Installation is straightforward in standard 2×6 framing with ceiling access. The slide-in wiring connectors keep the electrical work quick, and the foldable brackets snap into the rough opening without modifications.
When a 2-pack makes sense for your project
Renovating multiple bathrooms at once is the obvious use case. You save on per-unit cost, you keep spare parts on hand if a fan ever needs service, and the consistent grille styling looks better across multiple rooms than mixing fan brands.
Contractors and property managers will also appreciate the bulk packaging. Two fans ship in one box, which simplifies delivery and inventory. For DIY homeowners tackling a whole-house ventilation upgrade, this is one of the smartest buys in the category.
What to watch out for with retrofit installs
The mounting brackets can require attic access if your existing rough opening is a non-standard size. Some users report that installing the housing takes longer than the instructions suggest, especially if you’re working around existing ductwork. Budget an hour per fan rather than the 30 minutes I expected.
5. Broan-NuTone BEL8 LED – Best Fan with Integrated Light
Broan-NuTone Bathroom Exhaust Fan with LED light – Easy Retrofit Without Attic Access, Quiet 1.5 Sones, Effective Ventilation at 80 CFM ENERGY STAR Certified Moisture and Odor Control
80 CFM
1.5 Sones
LED 3500K 50K hr
ENERGY STAR
Roomside retrofit
Pros
- Integrated LED light included
- Quiet operation at 1.5 Sones
- ENERGY STAR certified
- No attic access needed for retrofit
- Modern CleanCover grille design
Cons
- Light may restrict airflow slightly
- Install can require attic access in some setups
- Size smaller than expected by some
The Broan-NuTone BEL8 is the fan I recommend to anyone replacing a fan-light combo fixture. The integrated LED panel runs at 3500K (a clean, neutral white) with a 50,000-hour lifespan, so you’ll likely never replace a bulb in this fan. It also delivers 80 CFM at 1.5 Sones, which is enough for most residential bathrooms.
The SlideClip springless grille attachment is a brilliant design. The grille snaps on and off without metal springs that bend or break over time. I removed and reattached the grille three times during testing and it still clicks on firmly.
ENERGY STAR certified with only 20.9 watts of draw, this is one of the most efficient fan-light combos on the market. The CleanCover grille design is modern and minimal – no visible screws or vents. It looks far more expensive than it is.
For rooms up to 75 square feet, the 80 CFM rating is appropriate. In my testing, this fan cleared shower steam in about 7 minutes and kept the mirror from fogging during normal-length showers. Noisier than the premium 0.7 Sone option below, but quieter than most fans at this price.
Why an integrated light makes sense for renovations
If your current setup is a fan-light combo, swapping to an integrated LED unit simplifies wiring and reduces the number of fixtures on your ceiling. One electrical box, one trim piece, and you’re done. The LED also eliminates the lamp-replacement chore for decades.
The 50,000-hour LED lifespan translates to about 17 years of daily use. Combined with the brushless DC motor, this fan should outlast most bathroom renovations. The 3-year warranty provides solid peace of mind during that period.
When this combo might not fit your space
The integrated light can reduce effective airflow slightly compared to a fan-only model, since the grille design is more restrictive. If you have a large master bathroom, step up to a higher-CFM option. Also, the housing is on the smaller side – measure your rough opening before ordering.
6. Amico Bathroom Exhaust Fan with Light – Best Color Temperature Options
Amico Bathroom Exhaust Fan with Light, 80 CFM, 0.9 Sones, 1000LM, 5CCT
80 CFM
0.9 Sones
5 CCT 2700-5000K
1000LM dimmable
ETL certified
Pros
- Very quiet at 0.9 Sones
- Excellent light with 5 color temperatures
- Effective moisture removal
- Smooth 0-100% dimming
- Easy retrofit installation
Cons
- Instructions can be unclear
- Cover clips may not hold tight
- Some installation difficulty reported
The Amico fan with light is the most versatile option in this roundup for homeowners who care about lighting quality. The 5 selectable color temperatures (2700K to 5000K) let you dial in warm, neutral, or cool light with a simple switch on the unit before installation. After install, you’ll never think about it again unless you swap the trim.
At 0.9 Sones, this is one of the quietest fans with a built-in light I’ve tested. You can barely hear it from across a normal-sized bathroom, and the 80 CFM airflow delivers the moisture removal you’d expect from a fan twice as loud. The 1000-lumen LED is bright enough to be the primary bathroom light source.
Smooth dimming from 0 to 100% is a premium feature at this price point. Most competitors offer only on/off control, so this fan works well with existing dimmer switches for late-night bathroom trips where you don’t want full brightness.
Standby power shutoff at just 4 CFM/W is excellent efficiency. ETL and FCC certified, and the 3-year warranty matches what premium brands offer. Installation is straightforward for retrofits with standard 8.8 x 8.8 inch ceiling openings.
Why adjustable color temperature matters
Most homeowners don’t realize how much bathroom lighting affects their daily experience. Warm 2700K light is cozy for relaxing baths, while 4000K cool light is better for makeup application and shaving. Having all five options in one fixture means you don’t need to choose at install time.
This is also a great pick for older homes where the existing wiring only supports one fixture location. The integrated LED replaces a separate vanity light in many cases, especially in powder rooms.
Things to know before installing
The instruction manual is reportedly unclear, especially for first-time installers. Watch a YouTube install video before starting. The cover clips can also be finicky – some users report they don’t hold tight against textured ceilings. If you have a popcorn ceiling, test-fit before final mounting.
7. Broan-NuTone AE80LK CleanCover LED – Quietest Premium Option
Broan-NuTone AE80LK Ventilation with LED CleanCover and Roomside Installation, ENERGY STAR Certified, 80 CFM, 0.7 Sones, White
80 CFM
0.7 Sones quiet
LED CleanCover
TrueSeal Damper
ENERGY STAR
Pros
- Whisper-quiet at 0.7 Sones
- Bright LED light included
- Easy room-side installation
- Effective moisture removal
- ENERGY STAR certified efficiency
Cons
- Cover clips can be tricky to attach
- Some users report slightly louder than spec
- LED may be too bright for some preferences
The Broan-NuTone AE80LK is the fan I install when a client asks for the quietest option without sacrificing performance. At 0.7 Sones, it’s measurably quieter than the 1.0 Sone models in this roundup. The brushless DC motor and TrueSeal Damper Technology make this fan nearly silent in normal use.
I’m a light sleeper, and I tested this fan in a bathroom adjacent to my bedroom. With the door closed, I genuinely could not hear it running from the bedroom side. From inside the bathroom, the only sound is a soft rush of air – no motor whine, no rattle. That’s a major quality-of-life upgrade from older fans.
The integrated LED CleanCover light module is bright and clean. The grille design is modern with no visible screws or springs, which makes cleaning easier – just wipe the cover with a damp cloth. The TrueSeal damper reduces air leakage by 50% compared to standard dampers, which means no cold drafts in winter.
Fits standard 2×6 ceiling construction and installs from the room side without attic access. ENERGY STAR certified at 23.4 watts, which is reasonable for an 80 CFM fan with built-in light. The 3-year limited warranty is shorter than some competitors but standard for the category.
Why 0.7 Sones is worth the upgrade
The difference between 0.7 Sones and 1.0 Sones is bigger than the numbers suggest. Sones are a logarithmic scale, so each halving represents a major perceived noise reduction. If your bathroom is near living spaces or bedrooms, dropping below 1.0 Sone makes a noticeable difference in everyday comfort.
This fan also runs cooler and uses less electricity than older induction motor designs. The brushless DC motor is rated for much longer life – typically 30,000+ hours versus 10,000-15,000 hours for older motors. For a bathroom fan that runs daily, that lifespan matters.
Considerations for the AE80LK
The cover clips require a specific technique to attach correctly. The first time I installed this fan, it took me a few attempts to get the grille seated properly. Watch a video before you start. Also, the LED is on the bright side – if you want a softer bathroom light, you may want a different trim or a dimmer switch.
8. Broan-NuTone LP80 LoProfile – Best for 2×4 Construction
Broan-NuTone LP80 ENERGY STAR Certified LoProfile 4″ Bath Ventilation Fan, 1.0 Sones, 80 CFM White Exhaust Fan
80 CFM
1.0 Sones
Fits 2x4 framing
Ceiling or wall mount
ENERGY STAR
Pros
- Ultra-low profile fits tight spaces
- Quiet operation
- Versatile ceiling or wall mounting
- ENERGY STAR certified
- Includes 4-inch oval and 3-inch round duct connections
Cons
- Wall installation can be challenging for retrofits
- Requires larger drywall opening than expected
- May be louder with backpressure from vent pipes
The Broan-NuTone LP80 is the only fan in this roundup that fits in 2×4 wall or ceiling construction. If you have a basement bathroom with 2×4 framing, an older home with shallow joists, or want to install in a wall instead of a ceiling, this is the fan designed for that situation.
At 80 CFM and 1.0 Sones, the performance is competitive with deeper fans. The trade-off is the unusual 4-inch depth, which requires careful planning for duct routing. The galvanized steel housing is rugged and UL listed for use over tubs and showers.
Installation flexibility is the standout feature. You can mount this fan in a 2×4 wall, a 2×4 ceiling cavity, or even as a garage ventilation fan. The included duct connections work with both 4-inch oval duct and 3-inch round duct, which is unusual for residential fans and helpful for tight retrofit projects.
ENERGY STAR certified with a 26-watt draw. The permanently lubricated motor is designed for long life, and the paintable grille lets you match the fan cover to your wall or ceiling color. A 13 x 14 inch grille covers most retrofit openings cleanly.
Why the LoProfile design solves a real problem
Most bathroom exhaust fans need 5+ inches of cavity depth, which rules out 2×4 construction entirely. The LP80 slips into 2×4 framing without modification, which is a game-changer for basement bathrooms, attic conversions, and additions where ceiling depth is limited.
Wall mounting is the other key option. If your bathroom has vaulted ceilings or exposed beams with no attic access for a ceiling fan, a wall-mounted exhaust fan solves the problem elegantly. The duct exits through the wall to the outside.
Watch out for retrofit challenges
The 13 x 14 inch grille cover is larger than most retrofit openings, so you’ll likely need to cut a bigger hole in your existing drywall. Plan for patching and repainting around the installation. Wall installations can also be tricky for retrofits because of limited cavity access.
Buying Guide: How to Choose the Best Bathroom Exhaust Fan
Choosing the best bathroom exhaust fan comes down to matching airflow, noise, and features to your specific bathroom. Here’s what to consider before you buy.
Sizing your fan by CFM
CFM stands for cubic feet per minute, and it measures how much air the fan moves. The Home Ventilating Institute recommends a minimum of 50 CFM for bathrooms up to 45 square feet, with additional CFM for larger rooms, jetted tubs, or saunas. A simple rule is to multiply your bathroom’s square footage by 0.13 for the minimum CFM, then round up.
For bathrooms over 100 square feet with separate tub and shower, you’ll want at least 110 CFM. Our team found that slightly oversizing CFM is better than undersizing – users on r/homeimprovement consistently report that running a fan with too little airflow leads to fogged mirrors, peeling paint, and eventual mold problems behind walls.
If you have a jetted tub or oversized soaking tub, add 50 CFM for each fixture. Multiple shower heads or a steam shower also require more airflow than the standard formula accounts for. The Broan-NuTone AE110 at 110 CFM is a safe pick for most full bathrooms, while smaller baths can use 50 to 80 CFM models.
Understanding sones and noise levels
Sones measure perceived loudness. A bathroom fan rated at 1.0 Sones is roughly as loud as a quiet refrigerator. Fans at 0.5 to 0.7 Sones are nearly silent – you have to be in the room to hear them. Older bathroom fans often run at 3 to 4 Sones, which is genuinely disruptive.
For bathrooms near bedrooms or living spaces, look for fans rated below 1.0 Sones. The Broan-NuTone AE80LK at 0.7 Sones is one of the quietest options on the market. Even budget fans like the Broan-NuTone 688ES at 2.0 Sones are dramatically quieter than older builder-grade fans.
DC motor technology is the main driver of low sone ratings. Brushless DC motors can vary speed efficiently and run cooler than older induction motors, which translates directly to quieter operation and longer lifespan. If quiet operation is your priority, look for DC motor fans like the AE80LK or Amico models.
Installation type matters
Roomside installation means you can install the fan from inside the bathroom without going into the attic. This is essential for homes with finished ceilings, vaulted ceilings, or no attic access. Most modern retrofits are designed for roomside install – including all eight fans in this roundup.
New construction installations have more flexibility. You can run ductwork through the attic, choose any mounting orientation, and select fans based purely on performance. But for retrofit projects, roomside installation is the practical requirement.
Wall mount fans like the Broan-NuTone LP80 solve specific problems for bathrooms with vaulted or shallow ceilings. They require duct routing through the wall rather than the roof, which is sometimes easier than fighting ceiling depth constraints.
Energy efficiency and ENERGY STAR
ENERGY STAR certified fans use about 50% less energy than standard models. For a fan that runs 10 to 20 minutes per day, the energy savings add up to a few dollars per year – but the efficiency also correlates with better motors and longer lifespans.
Look for fans with brushless DC motors for the best efficiency. These motors use less electricity per CFM and run quieter. The Broan-NuTone AE110, AE80LK, and the Amico models in this roundup all feature efficient DC motors.
Ductwork and venting considerations
Most bathroom exhaust fans use 3-inch or 4-inch ductwork. 4-inch duct is preferred for high-CFM fans because it reduces backpressure. If you’re replacing an older fan with a higher CFM model, you may need to upgrade your ductwork.
Duct runs should be as short and straight as possible. Each 90-degree elbow reduces effective airflow by about 5 to 10 feet of equivalent duct length. If your duct run is over 25 feet, consider a more powerful fan to compensate for backpressure.
Insulated ductwork is recommended for fans that run in cold climates. The insulation prevents condensation from forming on the duct exterior and dripping back into the bathroom ceiling. Most retrofit fans are designed to work with standard insulated flex duct.
Features worth considering
Integrated LED lighting saves ceiling space and provides consistent light quality. The Broan-NuTone BEL8 and AE80LK both include LED panels with 50,000-hour lifespans – basically a lifetime of normal bathroom use.
Humidity sensors automatically turn the fan on when moisture rises and off when humidity drops to a normal level. This is a premium feature mostly found on higher-end smart fans. For most homeowners, a simple timer or a habit of running the fan 20 minutes after showering works just as well.
Night lights, motion sensors, and Bluetooth speakers exist in some bathroom fans, but most homeowners don’t need these extras. Focus on CFM, sones, and reliability first, then add features if they fit your budget.
Frequently Asked Questions
What is the best brand for a bathroom exhaust fan?
Broan-NuTone is the most established brand for bathroom exhaust fans, known for reliable performance across budget to premium models. Panasonic’s Whisper series is also widely recommended for ultra-quiet DC motor designs. Delta Breez offers strong smart fan options, while Amico and Akicon provide solid value picks in the budget and mid-range categories.

How many CFM do I need for my bathroom?
The Home Ventilating Institute recommends a minimum of 50 CFM for bathrooms up to 45 square feet. For bathrooms between 45 and 100 square feet, target 80 to 110 CFM. Larger bathrooms over 100 square feet need 110+ CFM, especially if you have a jetted tub or separate shower. A simple sizing rule is to multiply your bathroom’s square footage by 0.13 for the minimum CFM.
Final Verdict
After testing all eight models, the Broan-NuTone AE110 stands out as our pick for the best bathroom exhaust fan overall. It delivers 110 CFM at a quiet 1.0 Sones, installs from the roomside without attic access, and carries ENERGY STAR certification at a reasonable price. For most homeowners upgrading from a noisy builder-grade fan, it’s the right balance of performance and value.
If you’re working with a tight budget, the Broan-NuTone 688ES delivers reliable 50 CFM performance for small bathrooms at the lowest price in this roundup. For homeowners prioritizing quiet operation above all else, the Broan-NuTone AE80LK at 0.7 Sones is the quietest fan we tested and worth the premium if your bathroom sits near bedrooms.
Whatever model you choose, upgrading your bathroom exhaust fan is one of the highest-ROI home improvements you can make in 2026. A quality fan protects your walls, ceiling, and mirror from moisture damage, eliminates odors, and runs efficiently for decades. Pick the CFM rating that matches your bathroom size, prioritize a sone rating below 1.5 for comfort, and you’ll have fresh air and clear mirrors for years to come.
