FAQs
What are the benefits of using a humidistat fan?
Too much humidity in a room can lead to mould and mildew growth, especially in small or poorly ventilated household bathrooms or shower rooms, perhaps those without a window and natural light.
A humidistat fan draws the excess moisture out of the air and reduces the risk of mould growth and minimises the risk of health issues associated with mould over a long period, such as shortness of breath, watery eyes and a runny nose.
A humidistat timer also helps to combat overly dry air which can lead to irritation and dry, itchy skin.
Excess humidity also creates an ideal environment for pollutants and allergens such as dust mites and bacteria.
A humidistat fan helps to improve overall air quality and keep your bathroom or toilet fresh and hygienic, particularly after bathing.
As a humidistat only operates when needed, it is energy-efficient to run and consumes less energy than a traditional fan that relies on manual operation, which is more economical and can help to lower energy bills.
Here at YESSS Electrical, our fantastic collection includes several noise level options for quiet running at night, with no compromise on efficiency.
What is the difference between a bathroom extractor fan and a humidistat fan?
An extractor fan and a humidistat fan both remove excess moisture, warm air, unpleasant odours and allergens from a room.
The extractor fan operates by pulling in air from the room and expelling it through a vent or duct.
However, a humidistat fan is designed for the sole purpose of removing moisture from the air by monitoring humidity levels and activating or turning off as needed.
It's automatic, so there's no need for a pull cord next to your light switch.
How do I set up a humidistat fan?
Building regulations state that Humidistat extractor fans should be installed as high as possible on the wall, no more than 400mm below the ceiling. Once connected to a power source, the humidity sensor can be adjusted to turn on or off automatically once humidity levels reach a certain threshold.
Always refer to the manufacturer's guidelines and employ the help of a qualified electrician when needed for installation.
How do I know if I need a humidistat fan?
Humidistat fans are suitable for rooms that are prone to excess moisture in the air.
For instance, condensation and mould growth is a strong indicator of a high humidity level and excess moisture.
A humidistat extractor fan will help to reduce moisture, condensation and mould growth.
How should I clean and maintain a humidistat fan?
Regular cleaning of your humidistat fan will ensure it is operating at max efficiency once installed and can extend its lifespan.
For example, regular dusting of the grille and fan blades will prevent build-up of dirt and allow free, constant airflow without blocking the humidity sensor.
