How Humidity Sensing Bathroom Fans Work

Unlike traditional models that are connected to your lamp switch, these sensors have an inbuilt detection system that monitors the humidity in the bathroom. Whenever the moisture rises above the specified level, the fan automatically turns on, only switching off when the appropriate level has been restored.

Evidence of their incredible innovation is evident in their efficient, hushed operation. Your property will be maintained in the pristine state it’s in, with no nasty mold creeping in and causing potential health problems. 

While most are hydrostatically engineered to switch on and off, others run continuously at a controlled level, spiking only when the norm is exceeded. Forbes covers why it’s important to take home ventilation seriously for further reading.

Advantages of Bathroom Exhaust Fans:

The innovation in these pieces of technology make thousands of homes better across the country. Some of the benefits they offer are:

  1. They’re independent to set timers

Since they’re not connected to the home timer, they won’t be cut off until the moisture level is reestablished, not based on time. 

  1. No noise

They’re well designed to run quietly in the background without making a fuss, allowing a peaceful home.

  1. Easy to set up

Though functionally more advanced compared to cheaper extractors, they are structurally similar. This means that the installation process will be simple as you pop the old ones out and bolt these in.

Ventilation Requirements

Proper air circulation and sufficient ventilation are necessary for bathroom humidity fans. Air circulation is often calculated as a measure of cubic feet per minute, abbreviated CFM. This is a standard calculation for the airflow of a fan. The appropriate CFM will depend on the size of your bathroom.

When it comes to the bathroom fan’s drone, they are measured using sones, not decibels. This ultimately is a measurement of how loud the fans sound to the hearer. These are directly proportional, with lower values being less noisy.

Features of Bathroom Fan Humidity Sensors

Humidity sensor fans are often chosen based on personal taste and overall rating and performance. Common highlights range from moisture detecting features, fans with installed lights, and temperature lamps. “Smart” designs have an automated running system to switch on and off in response to the changing humidity. 

Most units come as a combination of two of these highlights, usually the fan and the light. Recent designs may even look like ordinary decorative lamps for a more stylish aesthetic. If you know you’re likely to be forgetful and leave the fan on all day, there are options with a timer incorporated as well.

Installing a Bathroom Sensor Fan

Installing a Bathroom Sensor Fan

Though most bathrooms have built-in exhaust fans, some of these may not be efficient at eliminating all the moisture out of your home. To fully enjoy the benefits of having a humidity sensing bathroom fan, you’ll need to have it properly installed. If you’re feeling brave, check out Wikihow for tips on how to set up the humidity bathroom fan.

Buying Guide: 

Each of these humidity sensing bathroom fans allows you to adjust their dampness responses to curb mold and mildew forming. Based on user preference, these may be set to very high or significantly reduced as needed. Making your choice when deciding how to choose a bathroom fan humidity sensor bath fan depends on various factors:

  1. Energy Consumption

Check for an Energy Star rating that qualifies and confirms that the appliance uses your electricity conservatively. A strong fan may keep the mold away and keep your room crisp, but if it’s hiking your electricity bill, then it’s not worth it. Fortunately, our ten picks are all Energy Star qualified and have decent energy consumption rates. 

  1. Sound When Running

The droning hum of a running humidity fan can make most people run mad. This is why most customers specifically search for the least noisy appliances with lower sone units. 

  1. Overall Design

Apart from the humidity fan’s functionality, it’ll need to fit in with the rest of your bathroom design. Bold, grotesque machines throw off your well thought out interior design, so the overall make is important. A good looking one doesn’t have to compromise of efficiency, and variations exist, with some having grilles installed. If the color is a concern, you could opt to have the fan painted since most of them come in a plain white shade.

  1. Kind of Sensor

Ultimately, you’ll have to decide between two options – the adjustable version and the fixed option. With the first one, you’ll have a lot more flexibility with changing it to the humidity level of your choosing at any time. The latter, however, allows you to fix the humidity point once, and after that, it’ll continue to run at that level. If you know you’re the forgetful type, you’ll appreciate the latter option that requires less control. 

  1. Size of The Bathroom

The dimensions of your bathroom greatly affect your choice in picking the best bathroom fan humidity sensor bath fan. Think of it this way – a tiny one won’t be able to reach all the corners, meaning your restroom will still be moist and funky. On the other hand, one that’s too big for the room will overpower it, throwing the airflow balance off. Additionally, this will end up being expensive when the humidity sensing bathroom fan is too powerful for the room it’s placed in.


What’s the appropriate ventilation measurement?

Based on the bathroom size, here are the recommended bathroom fan humidity sensor sizes:

  • For bathrooms smaller than fifty square feet, get a humidity sensor fan of fifty CFM.
  • If the bathroom is between fifty and one hundred square feet, a bathroom exhaust fan of one CFM for every square foot of the ground area will suffice.
  • When purchasing for anything larger than one hundred square feet, calculate the appropriate CFM for the toilet space, shower, and bathtub separately.
How often should humidity sensing bathroom fans be replaced?

On average, based on the unit’s quality, a replacement every decade or so should suffice. Maintaining it well ensures that it lasts as long as it should without any premature problems.

What is the best way to care for and maintain the fans?

If you’re seeing dust collecting on the unit, or fog settling on the mirror, it may be time to clean your fan. Follow the manual and switch the fan off before removing the cover and rinsing it over a sink. Make sure it’s dry before setting it back up again. WebMD tackles how to clean a humidifier properly.

Can I install it myself?

The humidity sensing bathroom fan units come with simple to follow user manuals for the adventurous. However, if you’re not familiar with setting up humidity fans, you should seek a professional to handle it.


One of the most taxing home-keeping practices is maintaining a fresh, humid-free bathroom. The only sure way to achieve this is to get the best humidity sensing bathroom fan and ensure that your home is mold-free. Not only is mold unsightly to look at, but it also has health-hazardous side effects. That’s why it’s essential to keep your restroom fresh and clean because a healthy home is a healthy you!
