Why Use An Exhaust Smart Fan?
Very few extractor fans on the market can be described as “Smart”. The Smart fan differs, it intelligently reacts to its environment, working almost autonomously because of its multiple sensors and the advanced technology associated with them.
Common activities increase the amount of moisture within a home, from washing machines, cooking or having a shower or bath.
It can also vary at any point through the day within a busy home or social housing situation due to peoples differing schedules and hygiene habits. This creates the perfect situation for mould to develop, as there is an abundance of warm and moist air in the property. There are also smells coming from the cooker that might be disagreeable to some of your family members or tenants.

- Timers reduce night time activity - Prevents night time noise and saves energy
- Humdistat measures moisture, only boosting the fan when required, saving energy

Frequently Asked Questions
The Essential Guide to Choosing the Right Bathroom Exhaust Fan
Introduction to Bathroom Ventilation
Proper ventilation in your bathroom is crucial for maintaining a healthy environment and preserving the integrity of your space. A high-quality bathroom exhaust fan is key to preventing mold, mildew, and other moisture-related issues. Whether you're building a new home or upgrading your current bathroom, understanding the different types of bathroom extractor fans and their features can help you make the best choice for your needs.
Why You Need a Bathroom Exhaust Fan
Moisture Control
The primary function of a bathroom ceiling exhaust fan is to remove excess moisture. This helps prevent damage to paint, wallpaper, and fixtures, extending the lifespan of your bathroom materials.
Odor Elimination
A good bathroom extractor fan helps eliminate unpleasant odors, ensuring that your bathroom maintains a fresh and clean atmosphere.
Improved Air Quality
By extracting airborne contaminants and excess humidity, bathroom exhaust fans improve the overall air quality, which is especially important in rooms with little or no natural ventilation.
Types of Bathroom Exhaust Fans
Ceiling-Mounted Fans
The most common type, bathroom ceiling exhaust fans, are installed in the ceiling and vent through the roof or an exterior wall. They are effective at removing moist air directly from your bathroom.
Wall-Mounted Fans
These fans are installed in the wall and are a good alternative if ceiling mounting is not feasible. Wall-mounted fans work well in bathrooms located on the ground floor or where attic access is restricted.
Inline Fans
For larger bathrooms or those requiring powerful ventilation, inline fans are ideal. These systems involve a fan unit that is mounted away from the bathroom, usually in the attic, with ducting that connects to an exhaust point in the bathroom ceiling.
Choosing the Right Bathroom Extractor Fan
Size and Power
The size of the fan you need depends on the size of your bathroom. Generally, you should aim for a bathroom exhaust fan that provides at least 1 CFM (cubic feet per minute) of air movement for every square foot of room area. For bathrooms larger than 100 square feet, add the CFM requirements for each fixture (toilet, shower, bathtub).
Noise Level
Consider the noise level of the bathroom extractor fan. Noise is measured in sones; the lower the sones rating, the quieter the fan. A fan rated at 1 or 2 sones will provide a comfortable noise level.
Features
Modern bathroom ceiling exhaust fans come with various features such as humidity sensors, motion detectors, and built-in lights. These can enhance functionality and convenience, adjusting the fan's operation to specific conditions or providing additional illumination.
Energy Efficiency
Look for bathroom extractor fans that are ENERGY STAR rated for energy efficiency. These models are better for the environment and will save you money on electricity bills over time.
Installation Considerations
Proper Venting
Ensure that your bathroom exhaust fan is vented to the outdoors, not just into an attic or crawl space. Improper venting can lead to moisture problems in other areas of your home.
Professional Installation
Consider hiring a professional to install your bathroom extractor fan, especially if you are not experienced with home electrical systems. Proper installation ensures that the fan operates efficiently and safely.
