Top 5 Best Delta Bathroom Exhaust Fans

Installing a quality exhaust fan in your bathroom introduces a number of advantages, with the most important one being the reduction of humidity.

As you probably already know, an excessive amount of humidity can turn a bathroom into an ideal breeding environment for mold and mildew, which, in turn, can seriously damage the walls of your home.

However, these convenient appliances can also eliminate the so-called “foggy mirror syndrome”, reduce airborne contaminants, as well as keep unpleasant odors at bay. If you’d like to enjoy all of these benefits and have already decided to get yourself a brand new bathroom exhaust fan, you’ve probably bumped into a very common dilemma – which brand should I go with?

Besides Air King and Broan-NuTone, Delta Electronics is probably the most well-known manufacturer of bathroom exhaust fans. In this article, I’ll be taking a closer look at 5 of their most popular models and help you decide whether this particular brand is the right choice for your needs.

The Best Delta Bathroom Exhaust Fan: Delta VFB25AEH BreezSignature

BreezSignature Exhaust Fan


  • Quiet (2.0 Sones)
  • LED indicator light
  • 130 CFM of air-moving power
  • Equipped with a humidity sensor
  • Energy Star-qualified brushless motor

Out of all Delta bathroom exhaust fans listed in this roundup, this model is the best. And I’m saying this for a good reason – it is powerful, feature-rich, and it does its job just as advertised.

Due to the fact that it’s equipped with a humidity sensor, it switches on and off automatically (although you can also operate the model manually).

Its powerful, 130 CFM-rated brushless motor is Energy Star qualified and makes quick work of excess moisture, while the convenient LED indicator light tells the owner whether the appliance is currently in operation or not. This Delta fan is also relatively quiet, at 2.0 Sones.

Reviews of the Best Delta Bathroom Exhaust Fans

1. Delta RAD80L BreezeRadiance

Radiance fan


  • CFM rating: 80
  • Sone rating: 1.5
  • Dimensions: 14.38” x 8.25” x 5.5”

[amazon fields=”B00HPZUR42″ value=”button” button_text=”Check Price on Amazon”]

The very first Delta bathroom exhaust fan I’ll be taking a look at is RAD80L, a member of the company’s BreezeRadiance lineup and a genuinely premium-quality model.

The best feature of this particular unit is undoubtedly the fact that it’s equipped with a heater. It’s a 1300-watt heater that can effortlessly raise the temperature in the bathroom and make those morning showers much more pleasant.

Besides the heater and the fan itself, Delta RAD80L BreezeRadiance also has a light. This is an extremely useful feature and one that can provide some extra illumination in your bathroom.

Furthermore, this particular model is rated at 80 CFM. As you can already guess, this makes it ideal for 80 sq. ft. bathrooms.

Finally, RAD80L is very quiet – at only 1.5 Sones – and has rust-resistant galvanized steel housing.


  • DC brushless motor
  • Convenient light
  • 1300-watts heater
  • Very quiet (1.5 Sones)


  • Somewhat tricky installation

2. Delta GBR80 BreezGreenBuilder

Delta GreenBuilder fan


  • CFM rating: 80
  • Sone rating: 0.8
  • Dimensions: 10.75” x 10.75” x 5.75”

[amazon fields=”B00C2N9HCA” value=”button” button_text=”Check Price on Amazon”]

Next up is a member of Delta’s BreezGreenBuilder range – the GBR80 bathroom exhaust fan. What makes this particular model unique is the fact that it was designed exclusively for new construction, which is precisely why it comes together with hanger bars.

As its name suggests, the GBR80 is rated at 80 CFM. In other words, it is just as powerful as the model described above – RAD80L BreezeRadiance – although this one doesn’t have a heater.

It does, however, have a DC brushless motor that performs just as advertised and which bears the Energy Star certification. What is more, it is exceptionally quiet: this is the quietest Delta bathroom exhaust fan in this roundup, rated at only 0.8 Sones.

The last feature of this fan worth mentioning is the LED indicator light. While it certainly won’t provide illumination in your bathroom, it will tell you whether the unit is currently in operation or not.

All in all, a great choice as long as you don’t need a retrofit installation.


  • An ultra-quiet bathroom fan (0.8 Sones)
  • Simple, minimalistic design
  • Energy Star-qualified motor
  • LED indicator light


  • Not for retrofit installation

3. Delta ITG80LED BreezIntegrity

BreezeIntegrity Fan


  • CFM rating: 80
  • Sone rating: 1.3
  • Dimensions: 7.5” x 5.8” x 7.2”

[amazon fields=”B01MV83Q8C” value=”button” button_text=”Check Price on Amazon”]

Here we have yet another 80 CFM-rated fan from Delta – the ITG80LED BreezIntegrity. This is a potent appliance with a couple of convenient features that put it above the competition.

First of all, the Energy Star-qualified motor of this unit is very quiet when it’s working. With a 1.3 Sones rating, this is undoubtedly one of the quieter 80 CFM-rated fans you can find on today’s market.

Secondly, it is equipped with a dimmable LED light. This is an extremely bright light that can easily illuminate the entire bathroom.

As far as I’m concerned, this model is ideal for medium-sized bathrooms. You are bound to fall in love with its energy efficiency, quiet operation, and simple, minimalistic design.

The only thing I didn’t like is the somewhat tricky installation – the design of the unit’s wiring compartment is not the best one I’ve seen so far.


  • Energy-efficient brushless motor
  • Ideal for medium-sized bathrooms
  • Dimmable LED light
  • Very quiet (1.3 Sones)


  • Poor wiring compartment design

4. Delta SLM50 BreezSlim

Breezslim bathroom fan


  • CFM rating: 50
  • Sone rating: 2.0
  • Dimensions: 3.94” x 7.25” x 7.2”

[amazon fields=”B00C2N9CP2″ value=”button” button_text=”Check Price on Amazon”]

If you have a small bathroom, look no further. Rated at 50 CFM, the Delta SLM50 BreezSlim is an ideal exhaust fan for folks with smaller bathrooms.

The fact that this model is not as powerful as the rest of the fans on my list is also the reason why it sports an exceptionally compact design. You can, however, obtain the same model in the 70, 80, and 100 CFM-rated versions, and these, of course, have larger dimensions.

The low-profile housing of this bathroom exhaust fan makes installing it as easy as it gets. The SLM50 BreezSlim is not the quietest Delta fan out there, though – it is rated at 2.0 Sones.

Other features worth mentioning are the Energy Star certification, as well as the fact that Delta SLM50 BreezSlim is a retrofit-ready bathroom exhaust fan.

In summary, a perfect option for a smaller bathroom.


  • Great for smaller bathrooms
  • Energy Star certification
  • Very easy to install
  • Compact design


  • Not the quietest Delta fan (2.0 Sones)

5. Delta VFB25AEH BreezSignature

BreezSignature Exhaust Fan


  • CFM rating: 130
  • Sone rating: 2.0
  • Dimensions: ‎9.7” x 9.7” x 8”

[amazon fields=”B003O0MNHG” value=”button” button_text=”Check Price on Amazon”]

This is, in my opinion, the best Delta bathroom exhaust fan currently available on the market. The fact that it’s not the quietest model out there is its only disadvantage.

First of all, this model is extremely powerful – it is rated at 130 CFM. This means that it can effortlessly eliminate excess humidity from a large bathroom in a matter of minutes.

Secondly, it comes equipped with a humidity sensor. This feature controls the speed at which the fan removes excess moisture. Turning the humidity-sensing mode off is as easy as toggling a wall switch.

The unit also has a simple indicator light and its DC brushless engine bears the Energy Star certification.

If you have a large bathroom, look no further – Delta VFB25AEH BreezSignature has everything you need.


  • Equipped with a humidity sensor
  • Very powerful (130 CFM)
  • Energy Star-certified
  • LED indicator light


  • Could be quieter

Is Delta Electronics a Good Brand

Delta fan close-up

Established all the way back in 1971, Delta Electronics is one of the world’s best-known manufacturers of bathroom exhaust fans. It’s a Taiwanese company and one whose market cap currently stands at around 740 billion dollars.

To answer the question from the title – yes, Delta’s bathroom exhaust fans are exceptionally well-made and provide phenomenal performance. This is particularly true for the brand’s pricier models, which are typically feature-rich and effortlessly deal with excess moisture and humidity.

Delta Bathroom Exhaust Fans – Performance

The bathroom exhaust fans manufactured by this company come in a wide variety of designs and power ratings.

Delta Electronics offers fans that range from compact, 50 CFM-rated models that work extremely well in smaller bathrooms to large, 130 CFM-rated units that can deal with excess moisture in bathrooms with sizable square footage.

If you don’t know what CFM is, it’s an abbreviation for “Cubic Feet per Minute” and a measurement that can tell you how powerful a particular model is.

This rating makes picking the right exhaust fan for your bathroom quite easy. All you have to do is to get a model whose CFM rating equals the size of your bathroom (in square feet). For example, you’ll want to purchase an 80 CFM-rated unit if the size of your bathroom stands at 80 square feet.

Things become a bit trickier when it comes to larger bathrooms, though. If the square footage of your bathroom is over 100 sq. ft., you will have to assign a certain number of CFMs for each of your plumbing fixtures.

You can learn more about sizing a new bathroom fan in my CFM sizing chart article.

Delta Bathroom Exhaust Fans – Motors

One of the best things about the bathroom exhaust fans made by this company is that almost all of them come equipped with DC brushless engines. It goes without saying, but this makes them exceptionally energy-efficient.

That is precisely why a lot of their units bear the Energy Star certification. And due to the fact that they run so efficiently, Delta’s bathroom exhaust fans are also very quiet in operation.

The models reviewed in this article have Sone ratings (this measurement tells you how loud a particular unit is) from 0.8 to 2.0. An appliance of this type whose Sone rating stands below 1 is almost completely silent.

Delta Bathroom Exhaust Fans – Humidity Sensors

Wet shower stall

As I said, this brand’s exhaust fans are often rich in convenient features. One of these features is the humidity sensor, which is capable of detecting an increased amount of humidity in a bathroom and, consequently, automatically turning the machine on.

This same feature can also automatically turn the fan off once it detects a decreased level of moisture. Of course, all of this can be disabled if the homeowner wants to turn the appliance on or off by simply using the wall switch.

Delta Bathroom Exhaust Fans – Heaters

Delta Electronics also manufactures bathroom exhaust fans with integrated heaters.

A model that’s equipped with a 1000+ watt heater can effortlessly remove the morning chill from your bathroom. However, keep in mind that such appliances typically require a dedicated circuit back to the panel box.
