Cons

- Lower extraction rate
Xpelair is a household name in ventilation, and their 100mm Timer Fan is a popular choice for those who want a fan that runs after you leave the room. The adjustable timer can be set from 1 to 20 minutes, helping to clear lingering steam and prevent mould. It extracts 78 m³/h, which is adequate for standard bathrooms.
Some users note it is a bit louder than the Manrose, but the convenience of the timer feature outweighs this for many. It is a reliable and cost-effective way to add intelligent ventilation to your bathroom without needing a separate light switch or pull cord.
Silent 100mm Quiet Fan
Best for Low NoisePros
- Very high extraction rate
- Extremely quiet
- Long warranty
Cons
- May be larger than standard
- Price can be near £30 limit
The Silent 100mm fan lives up to its name, with many owners reporting it is barely audible when running. It boasts an impressive 95 m³/h extraction rate, the highest in this roundup, making it ideal for bathrooms that generate a lot of steam. The 3-year warranty also provides extra peace of mind.
Its physical size can be slightly larger than other 100mm fans, so check your available space before buying. For those who prioritise silence and powerful ventilation, this fan is a standout choice that often comes in just under the £30 mark.
Airflow 100mm Standard Fan
Best Basic ValuePros

- Good for small spaces
Cons

Owner reviews note it is functional but can be a bit noisy at 32 dB. It is a good choice for a spare bathroom or a rental property where you need a working fan at the lowest possible cost, but you may want to spend a little more for quieter operation.
Vent-Axia 100mm Lo-Carbon Fan
Best Energy EfficientPros

This fan is ideal for environmentally conscious buyers or those who leave their fan running for extended periods. It lacks a timer, but its low running cost means you can leave it on longer without worrying about your energy bill. It is a well-built, reliable fan that offers great long-term value.
What to check before buying a bathroom extractor fan
Before you buy, consider the size of your bathroom. A 100mm (4 inch) fan is standard for small to medium rooms. Check the extraction rate, measured in cubic metres per hour (m³/h). For a basic bathroom, aim for at least 75 m³/h. Noise level is also key; look for a fan rated at 30 dB or lower for quiet operation. Finally, check if you need a fan with a timer or humidity sensor for automatic control.
Mistakes to avoid when choosing a budget fan
A common mistake is buying a fan with too low an extraction rate for your room size, which leads to condensation and mould. Another is ignoring the noise rating; a cheap fan can be annoyingly loud. Do not forget to check the IP rating for moisture protection; an IPX4 rating is recommended for bathroom use. Finally, ensure the fan matches your existing ducting size, usually 100mm or 150mm.
FAQs

Is a bathroom extractor fan easy to install?
