10 Best Bathroom Exhaust Fans 2021

Best Bathroom Exhaust Fans

After a long, busy, and hectic day, nothing beats a hot shower. However, while steamy water can soothe your nerves, it can have the opposite effect in your bathroom, particularly if it isn’t properly ventilated. Excess humidity collects on space’s available surfaces, creating destruction in the form of cracking paint, peeling wallpaper, and bent cabinetry, among other things.

Furthermore, moisture accumulation promotes mold growth in drywall and caulking, putting indoor air quality at risk. After each bath or shower, particular renters and homeowners will ventilate their baths by opening a window. Many without windows, on the other hand, should think about adding a bathroom exhaust fan. The best bathroom fan successfully prevents extra steam, shielding the bathroom from mold and water contamination while also assisting with removing mirror fog and odors.

10 Best Bathroom Exhaust Fans

When it comes to bathroom fans, there is a wide range of options available at all price points, from basic versions to high-end fans with built-in lights, heaters, and motion sensors. Keep reading for a step-by-step guide to exploring the options—and don’t forget our top choices, which are listed below.

Size and Power of Fans:

The amount of air moving by a bathroom exhaust fan is measured by Cfm, which is the amount of air driven by the fan per minute. The CFM number will be listed on the product’s packaging, along with a recommended room-scale. As a general rule, homeowners can purchase a fan with a minimum CFM value equal to the square footage. For a 50-square-foot bathroom

Measure the bathroom and use the following statistical formula for even greater precision:

Assume your bathroom is eight feet wide, ten feet long, and eight feet tall. Then add eight by ten by eight by 0.13 to arrive at an answer of 83.2. In this scenario, a bathroom fan with a CFM rating of 80 will most likely suffice.

Noise:

An exhaust fan’s noise is measured in “sones,” and most fans have a sones level ranging from 0.5 to 6.0. Therefore, the fan will be louder when working if the sones number (usually written on the fan box) is lower. For example, a sones rating of 1.0 corresponds to the sound of a quiet refrigerator. A sones ranking of more than 4.0, on the other hand, could be loud enough to block out the shower singing.

Many vendors now make whisper-quiet bathroom fans. Try mounting a 6-inch ducting adapter for your fan instead of the usual 4-inch attachment if you’re concerned about noise. Air can move easier in the broader duct, so a 6-inch duct puts less strain on the fan and allows for quieter operation.

Built-in feature:

Many people want a bathroom fan with a lamp built-in. These fan/light combos make installation simple by allowing the customer to remove their existing light and replace it with the new fixture using the same wires. Then, when someone comes into the bathroom, some of these versions have motion sensors that switch on the lamp automatically.

The Humidity sensors that activate the exhaust fan when moisture levels exceed a certain amount, nightlights that provide a soothing glow for late-night bathroom guests, and built-in heaters that quickly warm the bathroom on cold winter mornings are all optional features in bathroom fans.

Ducting and Installation:

When you take moist air out of the toilet, it has to go elsewhere. Any bathroom vents exhaust into a home’s attic; however, this arrangement isn’t suitable because extra moisture in the attic will lead to mold problems. Instead, bathroom fans can be vented to the outside wherever possible.

You will vent the air from the side of your house if the bathroom is on the first floor of a multi-story building. As long as the external wall, a regular ceiling-mounted fan is used for this form of venting.

Build a wall-mounted fan that pumps the exhaust directly out the side of the house. Your bathroom has at least one external wall. Route the vented air to the attic and then, by ducting, either to a soffit under the roof’s eave or out via a vent pipe in the ceiling for any bathroom situated on the floor immediately below the attic.

You can install the Bathroom fans between the tub and the bathroom in a section of the ceiling free of joists or drains. Replacement fans should be mounted in the same spot as the old ones. Larger bathrooms can necessitate the use of several fans to ventilate the space effectively. Additional wires or a dedicated circuit are needed to control fans with other features, such as lamps, heaters, and nightlights.

1. Panasonic FV-0811VF5 WhisperFit EZ Retrofit Ventilation Fan

Panasonic FV-0811VF5 WhisperFit EZ Retrofit Ventilation Fan, 80 or 110 CFM
  • Retrofit Solution: Ideal for residential remodeling, hotel construction or renovations
  • Low Profile: 5-5/8-Inch housing depth fits in a 2 x 6 construction
  • Pick-A-Flow Speed Selector: Allows you to pick desired airflow from 80 or 110 CFM
  • Flexible Installation: Comes with Flex-Z Fast bracket for easy, fast and trouble-free installation
  • Energy Star Rated: Delivers powerful airflow without wasting energy

The ceiling fan is built with remodeling and reconstruction in mind. With permanent lubrication, galvanized steel housing, and a rust-proof finish, this fan is designed to work continuously. Under standard operating conditions, this fan can sustain a bathroom of up to 80 square feet with its 80 CFM.

This device is also ENERGY STAR certified, comes with a built-in damper for backdraft protection, and is simple to mount for professionals or the DIY handyman.  Smaller fans like this are usually used in smaller homes or homes without a lot of bathrooms. In most situations, an 80 CFM fan can accomplish its goal of eliminating humidity from the space. In addition, this unit will play a cost-effective role in holding your construction budget down if you’re building a home with a smaller range of showers.

The fan is suitable for use in enclosures, including tubs and baths, as long as it is attached to a GFCI-protected circuit. I’ve seen this unit in several homes’ main and guest bathrooms, as it can fit most bathrooms of that scale. However, it is in an external water-tight enclosure. Therefore, we don’t recommend it for an oversized master bathroom. We may also recommend a different model if the toilet has multiple shower/bath fixtures, a hot tub, or low outside ventilation

Pros
  • 80 cubic feet per minute (CFM)
  • Son of less than.3
  • This product is designed to run continuously.
  • Ideal for more extensive baths or shower/tub enclosures in the house.
Cons
  • None

2. BV Ultra-Quiet 150 CFM, 2.0 Sones Bathroom Ventilation & Exhaust Fan

BV Ultra-Quiet 150 CFM, 2.0 Sones Bathroom Ventilation & Exhaust Fan
  • 2.0 sone super quiet performance. Silent-Clever Technology
  • Mounting opening: 10.5" x 10.5". Height: 8". Stainless steel 4" duct collar
  • Ventilating for bathroom space up to 150 sq-ft
  • HVI 2100-certified, and UL Approved. Quality & performance assurance.
  • One-year limited product warranty with technical support service included.

At a great price, the BV Ultra-Quiet pulls extreme humidity. There isn’t a bathroom (at least on the suburban side) that this can’t accommodate, making it ideal for homeowners who want a large master bath or a bathroom with multiple shower/tub combinations (or maybe even a hot tub). You do not assume this model is the quietest at 2.0 Sones. And, unlike the models previously mentioned, it isn’t all quiet.

However, when compared to its strength, a 2.0 sone rating is meager. In addition, this unit’s permanently lubricated motors allow it to operate continuously, making it ideal for high-humidity areas and small bathrooms. However, you won’t get any extras like nightlights, heating lamps, or Bluetooth speakers. That may be a deal-breaker for some, particularly if you want to create your dream luxury bathroom. And the rest of us, though, this fan would fit in nicely with every big room setup.

Pros
  • There are no tones.
  • This product is designed to run continuously.
  • This Ideal is master baths and places with a lot of humidity.
Cons
  • None

3. Broan-NuTone 655 Bath Fan

Broan-NuTone 655 Bath Fan and Light with Heater, 70 CFM 4.0 Sones, White
  • FAN COMBO: Fan, light and 1300-watt heater function independently or together to provide comfort to your bathroom
  • DECORATIVE: Designer white polymeric grilles complement virtually any decor
  • DISCREET: Type IC (Insulation Contact) unit is installed into your ceiling so all but the light and white grille shows in your room for a clean and cohesive appearance
  • COMPACT: Fits 2" x 6" ceiling construction and works in bathrooms up to 65 sq. ft. for your convenience. Voltage: 120 V
  • EASY TO USE: Two- or three-function wall controls are available separately. A 20-amp circuit is required for use to ensure the best performance

Along with its 80 CFM engine, this exhaust fan has a 270W collection of heat lamps and a 60W incandescent bulb. So you get a power outlet and a separate nightlight and heater light in addition to the 80 CFM size. Consumers would appreciate the unit’s flexibility. The installer should mount the Aero Pure A515A and wire the light, heat lamp, and fan separately.

It means you should have a click or button for each part you want to monitor. When in the bathroom, switch on the light and heat lamp without blowing the fan, or turn on the heat and exhaust fan. It’s ideal for luxury bathrooms that want a few more perks to make them even more luxurious.

Pros
  • 80 cubic feet per minute (CFM)
  • This product is designed to run continuously.
  • Excellent for luxurious bathrooms that need a higher degree of comfort.
Cons
  • None

  • Precision engineered with DC brushless motor for extended reliability, this fan will outlast many household appliances
  • Galvanized steel construction resists corrosion
  • Duct: Detachable 4-inch Plastic Duct Adapter

For late-night bathroom breaks, the Broan 665 is a fun machine with a night light and heater. It isn’t the largest unit on the list, and it isn’t the quietest at four sones, but the price is right, and it can comfortably cover a 65-70 square foot bathroom. The heater in this machine isn’t a lamp, which is a plus. However, instead of dispersing heat in a toilet, the Broan 665 uses a metal blower wheel to spread it. It results in more consistent heating and a more pleasant atmosphere.

Pros
  • This product is designed to run continuously.
  • Metal blower heater included for even heating.
Cons
  • None

  • Seams sealed to inhibit radon leakage

This inline fan is air ventilation and noise control workhorse. It is built with energy conservation and quietness in mind. More specifically, this fan employs reverse pressure to remove radon gas from your home through your HVAC system. Within, unique fans filter radon from the air supply and reintroduce it as filtered air. The housing is also insulated to prevent radon from escaping during the filtering process.

It is a perfect machine that kills two birds with one stone if you live in a house with higher-than-normal radon levels.

Pros
  • 166 CFM
  • Design that saves energy
  • Filters radon from the air being circulated.

Find the Delta BreezSlim Bathroom Fan for bathrooms up to 50 square feet, as well as laundry rooms and service rooms. It moves 50 CFM of air, but with just 1.0 sones of noise, you might not even notice it’s on. We like this device because of its quiet service and how quickly it removes humidity, and how simple it is to install (which is done via a 3-inch duct connection).

Pros
  • High Service Quality
  • Remove Humidity
Cons
  • None

7. Broan-Nutone 670 Ventilation Fan

This model from Broan-Nutone saves money by omitting bells and whistles while losing efficiency. For example, though louder than some of its competitors, the standard bathroom fan does an excellent job of removing humidity and excess moisture from bathrooms up to 50 square feet. The fan may be placed on an external wall or built in the ceiling with a 3-inch vent link.

Pros
  • Excess moisture
  • Excellent job
Cons
  • None

A bathroom exhaust fan with a radiator, such as the Broan 9093WH, can warm it up while keeping moisture out. An exhaust fan, an onboard radiator, and a lamp are included in this combo model. The 1500-watt heater delivers a direct source of heat into your bathroom, allowing you to get out of the shower or steam up your morning routine. Space is illuminated by a 100-watt incandescent lamp, while the 7-watt night light is only in the middle of the night. The 70 CFM exhaust fan can transfer enough air in a bathroom of up to 65 square feet. The machine comes with a four-function wall switch that allows you to control each function independently.

Pros
  • Transfer enough Air
  • Four Function Wall
Cons
  • None

9. Hunter 83002 Ventilation Sona Bathroom Exhaust Fan

Hunter 83002 Ventilation Sona Bathroom Exhaust Fan with Light, Imperial Bronze...
  • 110 CFM, 3.0 Sones
  • This quiet bathroom exhaust fan is a sophisticated fixture with flowing scrollwork and a Imperial Bronze finish
  • Reduces excess moisture and humidity and circulates air to fight odors
  • ETL damp listed for use over shower or tub with GCFI circuit
  • 5-Year limited warranty

Find the Hunter Sona Bath Fan with Light for a discreet bathroom exhaust fan. This decorative exhaust fan resembles a standard flush-mounted light fixture outside, but it houses a 110 CFM engine on the inside.  The Hunter Sona is illuminated by two 60-watt light bulbs, with the option to add a smaller 7-watt bulb for a dim nightlight. People believe that this bathroom exhaust fan is attractive and may be mistaken for a light fixture.

However, the frosted layer on the dome diffuses the glare, necessitating the use of a second source of light in the bathroom. This bathroom exhaust fan is much quieter than any other top model, at 3.0 sones.

Pros
  • Attractive
  • Quiet
Cons
  • None

10. Broan-Nutone 682 Duct-Free Ventilation Fan

Broan-Nutone 682 Duct-Free Ventilation Fan, White Square Ceiling or Wall Exhaust...
  • VERSATILE FAN: Ventilation fan helps eliminate humidity, tobacco smoke, and cooking odors. Install the compact fan between ceiling joists or wall studs - wherever it's needed most!
  • EFFICIENT: Fan circulates air past replaceable activated charcoal filter to continually cycle the air in enclosed spaces. Minimum Construction Space Required- 2 x 4 inches
  • EASY INSTALLATION: Torsion springs grille mounting - no tools necessary for a quick and easy installation
  • DECORATIVE: Paintable polymeric grilles allow you to ensure the fan is cohesive with your existing decor
  • FEATURES: Plug-in, permanently lubricated motor with the Broan-designed polymeric blower wheel for high-quality operation every time. Motor snaps in and out for easy cleaning - no screws required

Consider a duct-free bathroom exhaust fan if you don’t have access to an exterior vent but also want to increase ventilation and air quality. For example, the Broan 682 has a fan that circulates air and a charcoal filter that absorbs odors.

For basement bathrooms or bathrooms without access to the attic, a duct-free bathroom fan is a decent option. Instead of an external vent, the hardwired fan purifies the air before recirculating it in the room. That means the fan works well in powder rooms and half baths to improve air conditioning and eliminate odors. Still, it isn’t recommended for more oversized bathrooms or controlling high humidity levels.

The product summary does not specify how much noise the device makes because it does not connect to a duct, so bear in mind that it is not silent.

Pros
  • Improve Air Condition
  • Eliminate Odor
Cons
  • None

  • CERTIFIED: ENERGY STAR qualified and HVI Certified to ensure the best quality for your home

Broan-QT NuTone’s Series bathroom fan is a whisper-quiet bathroom fan. This fan is rated at 0.3-sones, which means it is very silent, and you may not even notice it is on. The QT series fan has an 80-Cfm rating, making it ideal for bathrooms up to 75 square feet. This Broan-NuTone bath fan has a hanger bar system that allows it to be installed in several construction configurations (though it does need 2′′ x 8′′ space).

This high-performance bathroom exhaust fan uses 6-inch ducting, which is one reason for its ultra-low noise level. It’s also energy star and HVI accredited, but Broan isn’t just making claims; the industry backs them. This bathroom fan is mounted over a shower or bathtub if it is wired to a GFCI circuit.

Pros
  • Hanger bracket for fast mounting Ultra quiet at 0.3 sone
  • HVI accredited and Energy Star eligible
Cons
  • Output needs a 6-inch duct.

12. Delta Electronics VFB25AEH BreezSignature Humidity sensor fan

Sale
Delta Electronics (Americas) Ltd. VFB25AEH BreezSignature Humidity Sensor Fan,...
  • Noise level of 2.0 sones
  • Precision engineered with DC brushless motor for extended reliability
  • Easily switch in and out of humidity sensing mode by toggling wall switch
  • ENERGY STAR qualified for efficient cost-saving operation
  • Precision engineered with DC brushless motor for extended reliability, this fan will outlast many household appliances

Delta’s BreezeSignature is a high-end bathroom exhaust fan with a humidity counter. Based on the moisture level, the humidity sensor would turn the bathroom fan on and off automatically. It is a fantastic feature because it helps you leave the fan on for the recommended 15-30 minutes after a shower to extract moisture easily.

It’s also valuable for households where you know people don’t use the bathroom fan, and you want to avoid mold or wall damage. By merely toggling the wall switch for manual use, you can disable the humidity sensor. A DC brushless motor has been used in the design of this bathroom fan, which can outlast many other household appliances.

It even has an indicator light on the grille, so you can see if the fan is running even if you can’t hear it. This fan has an average CFM of 80 and a sone rating of 0.8 to 2.5, depending on the fan level.

Pros
  • For automatic on/off, a humidity sensor is used.
  • 8 to 2.5 sones of silence
  • Brushless DC motor
Cons
  • There is no way to change the humidity level.

Final Thoughts:

Each of the bathroom exhaust fans we looked at has its own set of good and bad features. All of the items performed admirably, but one, in particular, stood out.

The bathroom ceiling fan is one of the few vent fans that allows users to choose the appropriate ventilation for their bathroom height. Assume you have a smallish to medium-sized toilet. But the efficiency of a bathroom exhaust fan is more significant, and this model outperformed its competitors. Panasonic is also one of the few firms that have a lengthy warranty on parts.
