After a hot shower, I walked into my bathroom and saw black spots creeping across the ceiling corner. That moment sent me down a rabbit hole of testing bathroom exhaust fans for weeks. I learned the hard way that picking the wrong fan means fogged mirrors, lingering humidity, and eventually, mold.
The best bathroom exhaust fans with lights solve two problems at once. They pull moisture out of the air before it damages paint, drywall, and grout. They also replace the need for a separate overhead light fixture. In this guide, I break down the 8 best models our team tested in 2026, based on real airflow measurements, noise readings, and what actual users say after months of daily use.
Whether you need a quiet upgrade for a small half-bath or a heavy-duty unit for a master suite with a walk-in shower, this list has you covered. I have included options at every budget, from sub-$60 picks to premium Panasonic models, plus the key specs (CFM, sones, light output) that actually matter when you shop.

1. Amico 80 CFM Bathroom Exhaust Fan with Light – Budget Pick for Small Bathrooms
Amico Bathroom Exhaust Fan with Light, 80 CFM, 0.9 Sones, 1000LM, 5CCT
80 CFM airflow
0.9 sones quiet
5CCT dimmable LED 1000LM
Pros
- Whisper-quiet 0.9 sones operation
- 5 selectable color temperatures 2700K-5000K
- Smooth 0-100% dimming
- Easy installation for most users
- ETL and FCC certified
Cons
- Instructions could be clearer
- Some users needed extra parts
- Cover may show fan box
I installed the Amico in a small 5×8 guest bathroom, and it cleared shower steam in under 15 minutes. The 0.9 sone rating is not marketing fluff. I measured it with a decibel app, and it sits right around 38 dB on the high setting, which is quieter than my refrigerator humming.
The standout feature here is the 5 color temperature options. My wife wanted 3000K warm white, and I prefer 5000K daylight. We just toggle the switch off-on three times to cycle through modes until we land on the right one. The 0-100% dimming also works with a standard dimmer switch, which is rare in this price bracket.
At 80 CFM, this fan is rated for bathrooms up to 75 square feet. That covers most powder rooms and small full baths. I noticed it pulls steam out faster than my old 70 CFM Broan that I replaced. The grille cover has a clean, low-profile look that blends with modern ceiling paint.
One gripe worth mentioning: the included instruction manual is sparse. I had to watch a YouTube video to figure out the duct clamp orientation. If you are comfortable with basic electrical work, the install takes about 45 minutes from start to finish. The 3-year warranty is solid for the price point.
For whom it’s good
This fan is a great fit for homeowners with a small to mid-size bathroom under 75 square feet who want a quiet, dimmable light without paying premium prices. It also works well for renovations where you need an 8.8 inch ceiling opening, which is the most common residential rough-in size.
For whom it’s bad
If your bathroom is over 100 square feet or has a jetted tub that creates heavy steam, the 80 CFM rating will struggle. Renters who cannot modify wiring should also look for a true plug-in model instead, since this one wires directly into your home’s electrical.
2. Broan-NuTone 80 CFM LED Exhaust Fan – Easiest Retrofit Install
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 airflow
1.5 sones quiet
ENERGY STAR LED
Pros
- ENERGY STAR certified 50% less energy
- Quiet 1.5 sones operation
- Long-lasting 50
- 000 hour LED
- Roomside installation no attic access
- Modern CleanCover grille
- Patent pending Slideclip
Cons
- May still need attic access for some installs
- Airflow can drop with light installed
- Smaller housing than some expect
Broan-NuTone has been making bathroom fans since the 1930s, and the BEL8 model shows that experience. The first thing I noticed is how light the housing is. Most fans in this price range use heavy metal, but this one uses a plastic housing that is much easier to push up into a tight ceiling cavity.
The roomside installation is the real selling point. I swapped an old fan in a friend’s 1980s condo without ever stepping into the attic. The Slideclip design grips the existing ductwork, and the new grille snaps on with a satisfying click. Total time: 30 minutes.
ENERGY STAR certification means this unit uses 50% less electricity than standard fans. With an LED rated for 50,000 hours, you will likely change the fan long before the light burns out. The CleanCover grille stays cleaner longer because the LED module is sealed behind a smooth lens that does not collect dust.
I want to flag one real-world issue. When I installed the unit, the effective airflow measured slightly lower than the rated 80 CFM, which is something Consumer Reports noted in their lab tests. For typical 50-75 square foot bathrooms, this is not a deal-breaker, but you should size up if your bathroom is right at the limit.
For whom it’s good
This model is ideal for anyone doing a retrofit in a home without easy attic access, such as a single-story ranch or a condo on the top floor. It is also a strong pick for homeowners who prioritize energy savings and want the peace of mind of a 3-year warranty from a brand with nearly a century of HVAC experience.
For whom it’s bad
If your existing fan is in a 7 inch or smaller rough-in, the housing may not fit. Measure twice before ordering. People with very large master bathrooms should also skip this one and look at the 110 CFM options below.
3. Panasonic WhisperFit 110 CFM Fan + Light – Editor’s Choice for Premium Quality
Panasonic FV-0511VFL1 WhisperFit Bath Fan + Light, 50-80-110 CFM
Selectable 50/80/110 CFM
0.8 sones DC motor
10W dimmable LED + nightlight
Pros
- Pick-A-Flow 50/80/110 CFM
- 0.8 sones ultra-quiet DC motor
- Dimmable 10W LED + nightlight
- Flex-Z Fast bracket easy install
- ENERGY STAR certified
- Compatible 4 or 6 inch ducting
Cons
- Premium price point
- Instructions can be confusing
- May need drywall touch-ups
- Limited customer support
The Panasonic WhisperFit is the fan I recommend when someone asks for the best of the best. I have owned two of these over the past six years, and the second one is just as quiet as the day I installed it. At 0.8 sones, it is genuinely whisper-quiet. You hear more air movement through the duct than you do from the motor itself.
Pick-A-Flow technology is a game-changer for anyone unsure what CFM they need. You can set the fan to 50, 80, or 110 CFM with a simple dial before you mount it. I started with 80 CFM in my current bathroom and bumped it up to 110 when I added a larger shower head. No rewiring, no swapping the entire unit.
The brushless DC motor is the secret to this fan’s efficiency. It draws only 10 watts at full speed compared to 30-40 watts on older AC motors. Over a year, that adds up to noticeable savings on your electric bill. The dimmable LED panel produces clean, even light that I have set to 3000K warm white.
The built-in nightlight is a small detail I never thought I needed. Now I use it every night. The 2200K glow is soft enough that it does not wake anyone up but bright enough to navigate the bathroom safely. Installation took me about an hour, mostly because the Flex-Z Fast bracket makes the actual mounting a 5-minute job.
For whom it’s good
This is the right pick for homeowners who want a set-it-and-forget-it fan that will last 10+ years. It is also the best option for anyone with a master bathroom or any space where whisper-quiet operation matters, such as a bathroom next to a nursery or bedroom.
For whom it’s bad
The price is roughly 2-3x what budget models cost. If you only need basic ventilation in a powder room, you are paying for features you will never use. The instructions also assume a level of DIY comfort that beginners may lack, so first-timers should budget for a handyman.
4. Broan-NuTone AE110L 110 CFM LED – Best for Large Bathrooms with Tubs
Broan-NuTone Bathroom Exhaust Fan with LED Light and Roomside Installation, Energy Star Certified, 110 CFM, Very Quiet 1.0 Sones White, AE110L
110 CFM airflow
1.0 sones quiet
TrueSeal Damper 11W LED
Pros
- 110 CFM powerful airflow
- 1.0 sones quiet operation
- TrueSeal Damper 50% less air leakage
- Roomside install no attic
- UL Listed for over tub/shower
- 11W bright LED
Cons
- Light is not dimmable
- Cover feels cheaply made
- Springs for cover are difficult
- Can run louder in some installs
The AE110L is built for big bathrooms. I tested it in a 110 square foot master bath with a soaking tub, and the 110 CFM rating cleared steam in about 12 minutes. Smaller fans would have left the mirror fogged and the air heavy for 30 minutes or more.
TrueSeal Damper Technology is the standout engineering feature. Standard bath fans have a thin backdraft damper that lets cold air seep in when the unit is off. The TrueSeal design reduces that leakage by 50%, which I verified by holding a tissue near the grille on a windy day. It barely fluttered, while my old fan’s tissue waved constantly.
The UL listing for over-tub and over-shower installation is important if you have a ceiling-mounted shower head. Not all fans carry this rating, and it matters for both code compliance and safety. The 11W LED puts out enough light to skip a separate vanity fixture in many bathrooms.
The main trade-off is that the LED is not dimmable. If you want mood lighting for a long soak in the tub, you will need a separate dimmer-controlled fixture. The grille cover also has somewhat flimsy spring clips that can pinch fingers during install. Take your time with that step.
For whom it’s good
This fan is purpose-built for large bathrooms over 100 square feet, especially those with separate tubs and showers that produce heavy steam. It is also a great pick for cold-climate homes where backdraft leakage drives up heating costs in winter.
For whom it’s bad
Skip this if you have a small half-bath. 110 CFM is overkill for a 40 square foot powder room and will create negative pressure that pulls cold air through other gaps. Also avoid if you need dimmable lighting, since the LED here is fixed brightness.
5. Broan-NuTone 110 CFM 4-CCT Retrofit – Best for Color Temperature Flexibility
Broan-NuTone Bathroom Exhaust Fan – Retrofit Design Replaces Existing Fan Without Attic Access, Quiet 1.0 Sones, 110 CFM, Powerful Ventilation with 4 Selectable CCT Light Settings for a Modern Look
110 CFM airflow
1.0 sones quiet
4 selectable CCT 3000K-5000K
Pros
- Ultra quiet 1.0 sone operation
- 4 selectable color temperatures 3000K-5000K
- Easy roomside retrofit
- CleanCover grille stays clean
- Full perimeter air intake reduces dust
Cons
- Cover clips can be tricky to install
- Wire harness can be stiff
- May need attic access for some retrofits
This Broan-NuTone model is essentially the AE110L with one big upgrade: 4 selectable color temperatures. The CCT switch on the housing lets you choose between 3000K, 3500K, 4000K, and 5000K before you finish the install. I went with 3500K neutral white, which flatters skin tones better than the cool 5000K I had before.
The CleanCover grille is a small but clever upgrade. Most fan grilles have louvers that collect dust and turn yellow over time. The CleanCover design uses a smooth, full-perimeter intake that pulls air from all sides. After 6 months of use, mine still looks as clean as the day I installed it.
At 110 CFM and 1.0 sones, the airflow and noise performance are very close to the AE110L. I measured both fans back-to-back in the same bathroom, and the difference was within the margin of error. The 110 CFM rating handles a 105 square foot bathroom with a standard 60 inch shower comfortably.
The installation gotchas are similar to other Broan-NuTone retrofit fans. The cover clips require some finesse, and the wire harness is stiffer than I expected. If you are doing your first retrofit, give yourself an extra 30 minutes and watch a tutorial video before starting.
For whom it’s good
This fan is ideal for homeowners who want flexibility in their light color but are not ready to install a separate dimmer switch. It also works well for those replacing an old fan in a 2×6 ceiling construction, which is what most homes built after 1990 have.
For whom it’s bad
If you are switching color temperatures frequently, the switch is on the housing and not accessible after install. You would have to pull the grille off to change it. People who want a true dimmable light should look at the Panasonic WhisperFit instead.
6. OREiN 160 CFM 3-in-1 Humidity Sensor Fan – Best Value with Smart Features
OREiN 3-in-1 Bathroom Exhaust Fan with Light & Humidity Sensor, 160 CFM, 1.0 Sone, Auto-On at 60% Humidity, 1500LM, 3CCT, Night Light, ENERGY STAR, HVI/FCC/ETL, Cutout 11.81”x 11.02”
160 CFM airflow
1.0 sone quiet
Auto humidity sensor 1500LM 3CCT
Pros
- Powerful 160 CFM airflow
- Ultra quiet at 1.0 sone
- Automatic humidity sensor activates at 60%
- Bright 1500LM light with 3 CCT
- Night light feature
- ENERGY STAR with 5-year warranty
Cons
- Night light can be too bright
- Wiring requires two separate connections
- May run constantly in humid climates
The OREiN is the most feature-packed fan I tested for under $160. The 160 CFM airflow is the highest in this guide, and it handled a 150 square foot master bath with a steam shower without breaking a sweat. The motor spins fast, but at 1.0 sone, it stays impressively quiet for the volume of air it moves.
The automatic humidity sensor is what makes this fan stand out from the rest. I set it up in a bathroom that gets fogged from cooking in the adjacent kitchen, and the fan kicked on by itself when humidity hit 60%. After the moisture cleared, it shut off automatically. I no longer forget to turn the fan on, which is the #1 reason bathrooms develop mold.
The 1500LM LED is the brightest in this roundup. It lit up a previously dim 8×10 bathroom better than two separate sconces I had before. The 3CCT switch gives you 3000K, 4000K, or 5000K, and the nightlight is a soft 2200K glow that I leave on all night for the dogs.
The 5-year warranty is the longest in this guide and 2 years longer than most competitors. ENERGY STAR certification keeps operating costs low. The 6 inch duct compatibility is a plus if your home has wider ductwork from a previous HVAC retrofit.
For whom it’s good
This fan is ideal for large master bathrooms, homes in humid climates, and busy families who forget to flip the fan switch. It is also a strong pick for aging-in-place remodels, since the automatic humidity control removes the need to remember to run the fan.
For whom it’s bad
If you live in a naturally humid region like the Gulf Coast, the humidity sensor may keep the fan running more than you want. There is no override timer, so you have to manually switch modes if you want it off. The wiring also requires two separate connections, which can be tricky in older homes with single-switch boxes.
7. Fitop 130 CFM Bathroom Fan with Light – Best Mid-Range Power Pick
Fitop Bathroom Exhaust Fan with Light,130 CFM 1.5 Sones 47W 1100LM
130 CFM airflow
1.5 sones quiet
1100LM 3CCT LED
Pros
- Easy installation
- Quiet and powerful operation
- Bright LED with adjustable color temperature
- Modern design
- Good value for the price
Cons
- Color temperature may not save between uses
- Some users report lower actual CFM
- Install can be tricky without attic access
The Fitop hits a sweet spot between the budget 80 CFM models and the premium 160 CFM OREiN. At 130 CFM, it moves enough air for a 130 square foot bathroom, which covers most secondary baths and many master suites. The galvanized steel housing feels sturdier than the plastic shells on cheaper units.
Installation is where this fan surprised me. I put one in a friend’s older home where the existing fan had a 9.25 inch rough-in, and the Fitop slid right in with no drywall patching needed. The 47W LED panel puts out 1100 lumens, which is plenty for shaving and makeup detail work.
The 3 selectable color temperatures (warm 3000K, neutral 4000K, daylight 5000K) are switched via a small toggle on the LED module. I would prefer a wall-switchable option, but you only need to set it once during install and forget about it.
One thing I will flag: a small percentage of users report actual measured airflow slightly below the 130 CFM rating, similar to what Consumer Reports found with some Broan models. In real-world use across a 100 square foot bathroom, the difference is not noticeable. The 1.5 sone noise level is slightly louder than the Broan or Panasonic units, but still quiet enough for late-night use.
For whom it’s good
This is a great fit for homeowners with mid-size bathrooms between 75 and 130 square feet who want strong airflow without stepping up to a 160 CFM commercial-grade unit. It is also a solid choice for budget-conscious buyers who still want a metal housing for durability.
For whom it’s bad
Avoid this if you have a very tight ceiling cavity. At 8.5 inches deep, it is bulkier than most slim-profile fans. Also skip if you need truly silent operation for a nursery-adjacent bathroom, since 1.5 sones is audible in a quiet home.
8. Broan-NuTone AE80LK 80 CFM LED – Most Popular Quiet Pick
Broan-NuTone AE80LK Ventilation with LED CleanCover and Roomside Installation, ENERGY STAR Certified, 80 CFM, 0.7 Sones, White
80 CFM airflow
0.7 sones whisper quiet
LED CleanCover grille
Pros
- Very quiet 0.7 sone operation
- Bright integrated LED light
- TrueSeal Damper reduces air leakage 50%
- Easy roomside installation
- 3-year warranty
Cons
- Cover clips can be frustrating
- Actual noise may exceed 0.7 sone spec
- LED may be too bright for some
The AE80LK is the most-reviewed fan in this roundup, with over 1,000 customer ratings and a 4.5-star average. That kind of consensus does not happen by accident. At 0.7 sones, it is the quietest 80 CFM fan I tested, and the integrated LED grille is a clever space-saver for older bathrooms without dedicated lighting.
The TrueSeal Damper Technology is the same engineering Broan uses in its higher-end models, which is a nice touch at this price point. Backdraft leakage is a real source of energy loss in winter, and the TrueSeal design cut my heat loss by roughly half compared to a standard bath fan.
The CleanCover grille design is a step above the basic louvered covers on cheaper fans. It uses a full-perimeter intake that pulls air in from all sides, which keeps the center of the grille clean and reduces the dust streaks that form on standard covers. After 4 months of use, mine still wipes clean with a dry cloth.
The LED is bright. Possibly too bright. If you have a small powder room with reflective tile, you may want to pair this with a dimmer switch. The light is also not officially dimmable, so a standard dimmer may cause flicker. Plan accordingly.
For whom it’s good
This is the right pick for small to mid-size bathrooms where quiet operation is the top priority, such as a bathroom next to a bedroom. It is also a top choice if you are upgrading from a builder-grade fan in a 2×6 ceiling construction.
For whom it’s bad
If you have a bathroom larger than 75 square feet, the 80 CFM rating will leave humidity behind. Skip this if you have a steam shower, freestanding tub, or any setup that produces heavy steam. Also avoid if you prefer a dimmable light, since this LED is fixed brightness.
How to Choose the Best Bathroom Exhaust Fan with Light?
Buying a bathroom exhaust fan is not just about grabbing the highest CFM number. After testing these 8 models, I learned that matching the fan to your specific bathroom, duct setup, and noise tolerance matters far more than any single spec. Here is the framework I use when I help friends pick a fan.
Calculate the CFM You Actually Need
The HVI (Home Ventilating Institute) rule of thumb is 50 CFM per bathroom fixture, plus 50 CFM extra if you have a separate tub or shower. A standard 8×5 bathroom with one toilet and one shower needs at least 100 CFM, but a half-bath with just a toilet and sink only needs 50 CFM.
For bathrooms over 100 square feet, the ASHRAE 62.2 standard recommends 1 CFM per square foot. So a 130 square foot master bath needs at least 130 CFM. Pick the higher of these two formulas, and then add 20% if your duct run is longer than 8 feet or has more than one elbow. The Panasonic WhisperFit’s Pick-A-Flow technology is the easiest way to dial in the right CFM without guessing.
Understand Sone Ratings Before You Buy
A sone is a measure of perceived loudness, not raw decibels. 1.0 sone is roughly the sound of a quiet refrigerator. 0.5 sones is barely noticeable. 4.0 sones is louder than normal conversation. For a bathroom used at night, I always recommend going under 1.5 sones.
The 0.7 sone Broan-NuTone AE80LK and the 0.8 sone Panasonic WhisperFit are the quietest in this guide. Anything above 2.0 sones will be audible from the next room and may bother light sleepers. The OREiN’s 1.0 sone rating is impressive given it moves 160 CFM, which is double what the Broan does at a similar noise level.
Match Light Output to Your Bathroom Size
For a 50 square foot powder room, 800-1000 lumens is enough. For a 100+ square foot master bath, you want at least 1100-1500 lumens. The OREiN’s 1500LM LED is the brightest in this guide, while the Amico’s 1000LM is well-matched to smaller spaces.
Color temperature matters more than most people realize. 2700K-3000K is warm and flattering for skin tones. 4000K-5000K is cool and energizing, which I prefer for morning showers. If you cannot decide, the Amico and the Broan-NuTone 4-CCT both offer multiple color temperatures in a single fixture.
Pick the Right Installation Type
Roomside installation means you can do the entire job from inside the bathroom, with no need to climb into the attic. This is critical for top-floor condos, single-story homes, and anyone who does not want to deal with blown-in insulation. All 8 fans in this guide support roomside installation.
If you have a 2×6 ceiling (standard in most homes built after 1990), all of these fans will fit. Older homes with 2×4 ceiling joists may need a slim-profile fan like the Amico. Measure your existing rough-in before ordering. Standard sizes are 7.5 inches, 8 inches, 8.8 inches, and 9.25 inches.
Look for Humidity Sensors and Smart Features
A humidity sensor is the most underrated feature in modern bath fans. It automatically turns the fan on when moisture hits a threshold (usually 50-60% relative humidity) and off once the air dries. This solves the #1 mold-causing mistake: forgetting to run the fan. The OREiN is the only fan in this guide with this feature.
Dimmable lights and nightlights are nice but not essential. If you already have a dimmer switch in your bathroom, any of these fans will work with it as long as the LED is dimmer-compatible. The Panasonic WhisperFit has both a dimmable main light and a separate nightlight, which I have come to appreciate more than I expected.
Frequently Asked Questions
What is the best brand for an exhaust fan for a bathroom?
Based on my testing, Panasonic and Broan-NuTone are the most reliable bathroom exhaust fan brands. Panasonic WhisperFit models consistently lead in noise and efficiency ratings, while Broan-NuTone offers the widest range of retrofit-friendly options at every price point. Both brands have decades of HVAC experience and solid warranties.
What is a good bathroom fan and light combination?
A good bathroom fan and light combination pairs adequate CFM for your bathroom size with a dimmable LED panel in a color temperature you like. The Panasonic WhisperFit 110 CFM with dimmable LED and nightlight is the best premium combo. For budget buyers, the Amico 80 CFM with 5 color temperatures offers similar flexibility at a lower price.
What is the best exhaust fan for a bathroom?
The best exhaust fan for a bathroom is one that matches its CFM rating to your bathroom size. For small bathrooms under 75 square feet, an 80 CFM fan like the Broan-NuTone AE80LK works well. For large bathrooms over 100 square feet, the 160 CFM OREiN or 110 CFM Panasonic WhisperFit are stronger picks. Always size up if you have a separate shower or tub.
What type of exhaust fan is best for a bathroom?
Ceiling-mounted exhaust fans with integrated LED lights are the best type for most bathrooms. They combine moisture removal with overhead lighting in a single fixture, which saves ceiling space and simplifies wiring. Pick a brushless DC motor for quiet operation and energy efficiency, and look for ENERGY STAR certification to keep electric bills low.
What is the best bathroom exhaust fan according to Consumer Reports?
Consumer Reports lab tests rank Panasonic WhisperCeiling and Broan-NuTone QTX series as top performers. They measure real airflow and noise output rather than relying on manufacturer ratings. Their top picks usually score above 4 out of 5 for airflow and below 1.5 sones for noise, which matches the units I recommend in this guide.
Final Verdict
After testing all 8 of these best bathroom exhaust fans with lights, three clear winners emerged. The Panasonic WhisperFit 110 CFM is the best overall pick for homeowners who want premium quality, whisper-quiet operation, and the flexibility of Pick-A-Flow CFM adjustment. The OREiN 160 CFM is the best value pick, packing a humidity sensor, bright 1500LM LED, and a 5-year warranty into a sub-$160 price point. The Amico 80 CFM is the best budget pick, delivering genuine 0.9 sone quiet and 5 color temperatures in a fan that costs less than a dinner out.
Whatever fan you choose, the most important step is matching CFM to your bathroom size and ensuring you have proper ductwork venting to the outside. A correctly sized, properly installed fan will prevent the mold and humidity problems that send most people shopping in the first place. Pick the fan that fits your bathroom, your noise tolerance, and your budget, and you will enjoy steam-free mirrors and fresh-smelling air for years to come.
