Best Humidistat Extractor Fan of 2023

Included in this guide (scroll):

As you may know, extractor fans can be activated by a number of different modules. One of my favourite extractor fan control modules is the humidistat or humidity sensor.

A humidistat, also known as a hygrostat, is the type of module that activates when the humidity of your bathroom reaches a certain level. Once it reaches a specific humidity level, the extractor fan is activated and then extracts the air.

Frequently Asked Questions (FAQs)

What is the Best Humidistat Extractor Fan?

We found the Best Humidistat Extractor Fan to be the Xpelair C4HTS. It is one of the most popular humidistat extractor fans on the market, runs quietly at just 16dB, has two speed options (15l/s and 21 l/s), features a run-on timer, and more!

Are humidity extractor fans any good?

Humidity extractor fans can be very effective in reducing excess moisture in a room or area. They work by drawing in humid air and expelling it outside, which can help prevent mould growth, reduce the risk of respiratory problems, and improve overall air quality. However, the effectiveness of a humidity extractor fan depends on several factors, such as the size of the fan, the size of the room, and how often the fan is used. It is also important to properly maintain the fan, including regularly cleaning the filters and ensuring that it is installed correctly. Overall, humidity extractor fans can be a useful tool in managing humidity levels, but it is important to do your research and choose a high-quality fan that is appropriate for your specific needs.

What does a humidistat do on an extractor fan?

A humidistat is a device that measures the level of humidity in the air. When it is installed on an extractor fan, it helps to regulate the amount of moisture in a room or space by automatically turning the fan on or off depending on the humidity level. When the humidity is high, the humidistat will activate the fan to remove excess moisture from the air, which can help prevent mould and mildew growth, reduce odours, and improve indoor air quality. The humidistat also helps to save energy by only running the fan when it is needed, rather than constantly running it at full speed. Overall, the addition of a humidistat to an extractor fan can help to create a more comfortable and healthy living environment.

Should I get a bathroom fan with a humidity sensor?

Yes, it is highly recommended to get a bathroom fan with a humidity sensor. This type of fan can detect the level of humidity in the bathroom and automatically turn on and off accordingly. This is important because high humidity levels can cause mould and mildew growth, which can be harmful to your health and damage your bathroom. A bathroom fan with a humidity sensor can also help reduce moisture buildup, prevent condensation on mirrors and walls, and improve air quality. In addition, this type of fan is convenient and energy-efficient, as it only runs when needed. Overall, investing in a bathroom fan with a humidity sensor is a smart choice for maintaining a healthy and comfortable bathroom environment.

One thing to keep in mind is during hotter days, if the humidity in the air is high enough, it will trigger your humidistat to activate. This may mean that you will need to set it on a less sensitive level – 60% humidity should be more than sufficient. In addition, make sure that you are not constantly configuring or adjusting your humidistat as they are very sensitive modules and you may damage them by mistake. For this reason, many people will opt for a timer-controlled extractor fan over a humidity-sensing extractor fan.
