What to check before buying a bathroom extractor fan
Before you choose a fan, you need to know your room size. Measure the length, width, and height of your bathroom in metres, then multiply them together to get the cubic volume. Building regulations in the UK recommend an extraction rate of at least 15 litres per second (54 m³/h) for a standard bathroom, but a larger room or one with a shower needs more power.
You also need to decide on the fan type. Axial fans are simpler and cheaper, ideal for wall mounting with a short duct run. Centrifugal or mixed-flow fans are better for longer ducts or ceiling installations. Beginners should stick with axial fans for the easiest DIY fit.
Noise is another key factor. A fan rated under 30 dB is considered quiet enough for most homes. Look for models with a timer or humidistat so the fan runs long enough to clear steam after you leave the room.
Mistakes to avoid when installing your first fan
The most common mistake is undersizing the fan. If you buy a fan with too low an airflow, it will not clear moisture effectively, leading to mould. Always aim for a fan that exceeds your room volume by at least 20%.
Another error is ignoring duct length and bends. Every 90-degree bend reduces airflow by roughly 30%. Keep the duct run as short and straight as possible. Finally, do not skip the isolator switch. A 3-pole isolator is required by UK wiring regulations so you can safely work on the fan.
The 5 Best Bathroom Extractor Fans for Beginners
Manrose MF100T
Best Overall for BeginnersPros
- Very quiet at 25 dB
- Adjustable timer from 1-20 minutes
- Simple to install with included template
Cons
- No built-in humidistat
- Plastic grille can feel flimsy
The Manrose MF100T is the go-to fan for anyone new to DIY bathroom ventilation. Its 100 m³/h airflow is enough for most standard bathrooms up to 2.5 m x 2.5 m. The timer function is a real plus because it lets the fan run for a few minutes after you leave, clearing residual steam without wasting electricity.
Owner reviews consistently praise its quiet operation. At 25 dB, it is barely audible, making it ideal for bathrooms where noise might disturb others. Installation is straightforward with the cut-out template and push-fit spigot, though you will need basic wiring knowledge to connect the timer.
Xpelair Simply Silent DX100
Best Budget FanPros
- Very affordable price
- Quiet for a budget model
- Easy to clean removable grille
Cons
- No timer or humidity sensor
- Lower airflow than some rivals
The Xpelair Simply Silent DX100 is the ideal choice if you are on a tight budget but still want reliable extraction. It moves 95 m³/h of air, which is adequate for a small to medium bathroom. At 28 dB, it is quiet enough for most homes, though not as silent as the Manrose.
This fan is a basic on/off model with no timer. You will need to leave it running manually or wire it to a light switch. The simple design makes installation very easy, and the removable front grille allows quick cleaning. Owner reviews note that it is a solid performer for the price.
Vent-Axia 100mm Lo-Carbon
Best Energy EfficientPros
- Low energy consumption
- Timer and pull cord options
- Good airflow for the size
Cons
- Slightly louder than Manrose
- Installation instructions could be clearer
The Vent-Axia Lo-Carbon range is designed to use less electricity while still delivering strong performance. This 100 mm model moves 102 m³/h of air, making it one of the more powerful axial fans in this list. It comes with a timer that can be adjusted from 1 to 30 minutes, giving you flexibility after a shower.
Owner reviews highlight the energy savings over older fans, though some note the noise level is slightly higher than the Manrose at 27 dB. The fan is suitable for both wall and ceiling mounting. The included pull cord version is handy for rooms without a separate light switch.
EnviroVent Extractor Fan
Best with HumidistatPros
- Automatic humidity sensing
- High airflow for large rooms
- Overrun timer included
Cons
- Noisier than average
- More expensive
The EnviroVent Extractor Fan is perfect if you want a set-and-forget solution. Its built-in humidistat automatically switches the fan on when humidity levels rise and turns it off once the air is dry. This is ideal for preventing mould without you having to remember to flip a switch.
With a high airflow of 110 m³/h, it can handle larger bathrooms or en-suites. The downside is the noise level. At 30 dB, it is louder than the other fans on this list. Owner reviews say it is still acceptable for a bathroom, but it is not the best choice for a quiet space. The fan also includes an overrun timer for extra moisture removal.
Airflow Icon 15
Best for Small BathroomsPros
- Compact and low profile
- Very quiet
- Easy to install in tight spaces
Cons
- Lower airflow
- No timer or sensor
The Airflow Icon 15 is designed for small bathrooms, cloakrooms, or en-suites where space is limited. Its compact housing fits easily into tight ceiling or wall cavities. The 85 m³/h airflow is sufficient for rooms up to about 5 m³, making it a good choice for a downstairs toilet.
At 26 dB, this fan is very quiet, so it will not disturb anyone. It is a basic on/off model with no timer or humidistat, which keeps the price low and installation simple. Owner reviews appreciate its small size and discreet appearance, though some wish it had more power for larger spaces.
FAQs
Do I need a bathroom extractor fan?
Yes, if your bathroom has no window or you want to prevent mould and condensation. Building regulations in the UK require mechanical ventilation in most new bathrooms.
How do I choose the right size fan?
Calculate your bathroom volume in cubic metres and multiply by 10 for the minimum airflow in m³/h. For a 10 m³ room, you need at least 100 m³/h.
Can I install a bathroom extractor fan myself?
Yes, if you are comfortable with basic wiring and cutting a hole in the wall or ceiling. Always use a 3-pole isolator switch and follow local wiring regulations.
What is the difference between axial and centrifugal fans?
Axial fans are simpler and cheaper, best for short straight ducts. Centrifugal fans are more powerful and can push air through longer or bendy ducts.
How quiet should a bathroom extractor fan be?
Look for a fan rated at 30 dB or less for quiet operation. The Manrose MF100T at 25 dB is one of the quietest options.
Do I need a fan with a timer?
A timer is very useful because it lets the fan run after you leave, clearing residual steam. It is recommended for bathrooms with showers.
What is a humidistat fan?
A humidistat fan automatically turns on when humidity rises and off when it drops. It is a convenient hands-free option for preventing mould.
How do I clean my bathroom extractor fan?
Remove the front grille and wipe it with a damp cloth. Use a vacuum with a brush attachment to clean the fan blades and housing every few months.
Can I use a 100 mm fan in a 150 mm hole?
No, you need the correct diameter. A 100 mm fan requires a 100 mm hole. You can use a reducer adapter, but it will reduce airflow.
What does a backdraught shutter do?
A backdraught shutter prevents cold air and insects from coming back into the bathroom when the fan is off. Many fans include one.
Are bathroom extractor fans energy efficient?
Modern fans like the Vent-Axia Lo-Carbon are designed to use very little electricity, often under 10 watts. They are much cheaper to run than older models.
How long should a bathroom fan run after a shower?
Most experts recommend running the fan for 15 to 20 minutes after a shower. A timer fan makes this easy to set.
