In most cases, to improve ventilation, this means you will need to install a humidity extractor fan. This is especially important if opening a window is not an option. Without good ventilation, excess moisture can cause not only damage to your property, but it can also affect your health.

The next time you visit your bathroom, take a good look around. If you spot any of the following:

  • condensation on walls, ceiling or windows after a shower,
  • cracked paint,
  • wallpaper that is peeling,
  • mold or mildew growth, or
  • cabinets that don’t function properly anymore due to warping,

then you’re likely to have a humidity problem.

Bathroom Humidity Ventilation Fan vs Dehumidifier to Remove Moisture

Humidity in other areas of the house may be able to be controlled with a dehumidifier. However, bathrooms create a unique environment. Hot showers and baths that typically produce a lot of steam create intense bursts of humid air. This calls for a device that is specifically-designed to handle this type of situation.

While dehumidifiers are great for their intended purpose, they are not designed for situations like this. Dehumidifiers are better for other areas of the house where moisture is more constant (like living rooms, garages, basements, etc), rather than the intense environments created in bathrooms.

Instead of removing the moisture from the air (which is how a dehumidifier works), in environments like bathrooms, it’s better to actually remove the air and replace it with air that is less moist. This is what a bathroom extractor fan does. And by adding a humidity sensor, this automates the process, so you don’t even have to worry about it.

This is why the best option to keep your bathroom moisture-free is to use a bathroom exhaust fan with humidity sensor. However, if you need information on choosing a good dehumidifier, click here.

Best Bathroom Exhaust Fan Options

Before you head down to the hardware store and pick out one of the best bathroom exhaust fans with humidity sensor to solve all your bathroom humidity issues, let’s go over some of the things you need to consider before you make this purchase.

The Volume Of Air That The Fan Can Extract

You can’t identify the best bathroom exhaust fan for your needs just by grabbing the first one you see. You need to do a bit of homework so that you know roughly what kind of fan you need.

One of the main specifications of bathroom exhaust fans is the amount of air the fan can move each minute. This is measured in cubic feet per minute, or CFM. The CFM number should be noted on the packaging of any bathroom fan with humidity sensor.

Along with that notation will likely be a suggested room size the fan can easily service. Not sure what size to get? If you know the square footage of your bathroom, aim for a humidity ventilation fan that is close to that square footage figure.

The Amount of Noise That The Humidity Extractor Fan Makes

best bathroom exhaust fan

When was the last time you used a bathroom with an extractor fan that was so quiet you couldn’t hear it? Probably never. No-one wants a noisy fan, as these can be intrusive and disturb your sleep at night. Because of this, it has become a selling point for the best bathroom exhaust fans. And that’s why exhaust fan with humidity sensor manufacturers provide this data along with the other information you will find on the box of the fan you are considering purchasing.

The noise that the average humidity controlled extractor fan emits is rated in a measurement called sones. The majority of fans have a rating that falls somewhere between 0.5 and 6.0 sones. The lower the sone figure, the less noise the fan makes.

To help you further, a quiet refrigerator makes about 1.0 sones so any fan rated 1.0 or fewer sones is going to be as close to silent as possible. Fans that are rated at 4.0 sones or more are more noticeable and are probably going to disturb you, especially in quieter times such as when you are relaxing or at night.

Other Optional Extras

Some people shopping for a bathroom exhaust fan with humidity sensor like to have additional features. Depending on the make and model, you can find some with:

  • a fan/light combination. The inclusion of a light is a common extra and makes for a clean look on the bathroom ceiling.
  • Some have a sensor that detects motion and will automatically turn on the light. This is a handy feature if you find yourself wandering into the bathroom late at night.
  • Humidity sensors are another added feature worth considering. What these do is automatically turn on and pull air out of the bathroom once a pre-programmed humidity level is reached.
  • Some humidity ventilation fan models have a built-in nightlight that will provide a comforting glow throughout the night.
  • Some bathroom fans contain a built-in heater that will warm up the bathroom making it more comfortable on a cold winter’s night.

Where To Install The Fan and Blow Out The Air

So, you have found the best bathroom exhaust fan with humidity sensor and light. Now, what do you do with it? Well, let’s think about that for a moment.

If your goal is to move humid air away from the bathroom, it has to go somewhere. You can’t blow it into the hallway, as this will just move the humidity problem into another part of your house. This has to be considered when buying a bathroom extractor fan since units come with different attachments depending on where the exhaust air is wented.

Some homes are built in such a manner that the exhaust fan sends humid air from the bathroom into the attic. Since that air isn’t released to the outdoors, mold and mildew can form in the attic which can create more issues.

If your bathroom is on the first floor and you have a two-story home, you can install a bathroom exhaust fan, but you would need to ensure that ducting runs through the ceiling joists to an exterior wall and then outside of the house.

But what if you can’t get ducting to pass through the ceiling joists? If the bathroom has at least one exterior wall, you can vent the humid air outside by installing a wall-mounted fan.

If your bathroom is located directly below the attic, you can still use a ceiling exhaust fan to blow the moist air into the attic. However, you will have to do something else to vent this air from the attic. You can either add a soffit under the eaves of the roof to let the moist air escape outside or run a vent pipe to the outside through the roof.

If all you are doing is replacing an existing humidity sensor extractor fan that has given up or passed its effective lifespan, you can probably just install the new one where the old one was. This means you can make use of existing venting or other material that ensured that the moist air from the bathroom was released outside of your house.
