The best part of the fan is the 130CFM air capacity that can quickly move all the unwanted moisture and odor from your large bathroom and introduce a conditioned environment. Even though the fan has a considerable airflow capacity, but it keeps the sound level around 2.0, which means you will hardly hear any sound in your large bathroom.

It works so silently in large spaces that the manufacturer has added a LED indicator within the grille to indicate its operation.

Based on the freshness of the bathroom, you can set the fan in full speed or humidity control mode with a simple push on the on/off switch. However, the feature that takes all the attention is the precision-engineered humidity sensor with a humidity control model.

You can set the humidity level between 50% and 80%, and the fan will automatically start its magic when the humidity crosses the scale. The exciting part is that the fan will automatically stop spinning after 10 minutes when it senses the moisture has gone below the set level. Besides the fan indicator, you will also have another LED indicator which will indicate the working of the humidity sensor.

Now, you must be thinking with so much airspeed and feature; this humidity-sensing fan must consume a tremendous amount of energy. But surprisingly it is quite an energy-efficient and only consumes around 7.2-19.1-watts along with Energy Star certification.

With high performance and effective humidity sensitivity, you will also appreciate the white square-shape grille that looks well in most of the bathroom decors. Delta offers a 3-years warranty coverage with this model so you can use this device without any worry.

The hanger bar attached on all sides makes the installation process quick and easy. You can expect the exhaust to stay by your side for many years, and the rugged galvanized steel construction is partly responsible for it.

What are the Benefits of Installing a Bathroom Fan with

Humidity Sensor?

When you install a bathroom fan with a humidity sensor, it will treat numerous benefits and won’t be limited to just moisture removal. Let’s check out those benefits;

Automated Operation

The automated operation of the bath fan with a humidity sensor relieves you from the hassle of switching on the exhaust every time you use the bathroom.

When you shower, the sensor automatically senses the increased moisture level in the bath space and switches on the fan to maintain a balance. Some fans even come with different speed options based on the moisture level so it can create a fresh air quality while you use the bathroom.

Fresh Bathroom Space

Excess moisture in the bathroom leads to a musty odor, which can ruin the freshness of the toilet. With the automatic removal of excess moisture, the exhaust with a humidity sensor brings a freshness to your bathroom.
Not only that, but winter mornings or summer afternoons can also create a high humid environment in the bathroom even when you don’t use it, and it is not suitable for usage. So when your exhaust fan senses the high moisture level, it will automatically start its magic and maintain a fresh bathroom space so that you won’t face discomfort.

Automatic End

Another great perk of automated operation of the exhaust fan with a humidity sensor is that it will automatically shut off when the humidity reaches an acceptable level. It is a general scenario that many people often forget to switch off the exhaust fan while they are in a hurry.

Leaving the fan running, not only causes the removal of conditioned air but also leads to unnecessary use of electricity. Plus, when you keep the fan running for long hours, then there is a chance that the fan might catch fire due to heat buildup. So the automatic shutoff saves you from all the issues and ensures a safe bathroom.

Prevent Damages

Having an exhaust with an automatic humidity sensor prevents your bathroom from different kinds of damage and keeps up the good look. Not only it prevents the metal items, especially the bathroom pipes from getting rust but also saves the wooden furniture from getting cracks.

Plus, it protects the wall color from getting fluffy and maintains the pristine look of the bathroom. So ultimately, it bars you from spending a considerable amount of cost on renovation and also minimizes maintenance costs.

Bathroom Exhaust Fan with Humidity Sensor: What To Consider Before Buying?

Buying the best bath fan with humidity features is easy, but choosing it is where the trick lies. So we have put forward some vital factors that you should consider before buying:

  1. Adjustment In Humidity Sensor
  2. Bathroom Size
  3. CFM Rating
  4. Customizable Fan Speed
  5. Noise Level(Sones)

Adjustment In Humidity Sensor– Humidity sensor is an excellent tool in an exhaust fan that removes unnecessary moisture. But having the option to adjust the humidity would be helpful as you will be able to set the moisture level you prefer. Generally, a fan with a customizable humidity sensor gets a knob that allows you to change the relative humidity from 25% to 75%. Having customizable humidity will let you keep the loo slightly humid during winters when the weather is arid.

Bathroom Size – Before considering any exhaust fan, the first thing you should assess is your bathroom’s size to help you determine the CFM. Having an overpowered or underpowered exhaust fan would be a futile investment.
If you get an overpowered fan for a small bathroom can lead to air problems, which might affect other appliances in the bathroom. But if you go for an underpowered fan, then it won’t get the job done, and the excess moisture will cause numerous damage in the bathroom.

CFM Rating – With bathroom size, the next most crucial factor that you need to consider is the CFM rating because it determines the strength of the exhaust. Basically, the CFM rating tells you how much air volume the fan can move based on per square feet of the bathroom space.

So if you have a 50sq ft small bathroom, then you should look for exhaust with a minimum 50 CFM rating. However, if the exhaust has to cater to a large bath of 120sq ft, then you should go for 120 CFM. Besides, you should consider the number of fixtures in the bathroom because they obstruct the air movement.

Customizable Fan Speed – Once you have decided your CFM, now you need to determine whether you want a fixed or customizable fan speed. If you go for fixed fan speed, then the fan will run on full swing even if you don’t need that much exhaustion of moisture. But having an adjustable-rate allows you to choose the fan speed based on various conditions. Certain fans will give three to four-speed options, while some budget models only come with high and low-speed settings.

Noise Level(Sones) – You should never ignore the noise level of your fan, which is denoted in Sones. A fan that has a noise level of 1.0 Sones or below, then it would give you a quieter exhaust operation. So if you want a pleasing showering experience, then you should go for a low Sones rating. But if you think you can bear some fan noise, then you can go for a noise level between 2-4 Sones but not above that range.


When you get a bathroom exhaust fan with a humidity sensor, you will find a significant change in the freshness of your bathroom. Regardless of the fan airflow capacity, the humidity sensor works flawlessly by sensing the humidity level and automatically starts the fan to curb down the humidity. Proper ventilation is essential in any bathroom, and we think an exhaust with a humidity sensor will be ideal for that purpose.

Besides having a humidity sensor, the products, we have added also works quietly so that you can enjoy a peaceful environment while using the lavatory. Even though most of the products come with affordable pricing, but when you install them, you will see a significant improvement in air quality.

We have highlighted a buying guide that we hope will help you make a better decision for your convenience. However, if you feel you are still confused, you can contact us, and we will try to help you to narrow down your choice.
