10 Best Quietest Bathroom Fans 2025 in the UK

The Xpelair C4TSR Extractor Fan is designed for those seeking a quiet and efficient bathroom fan. With a noise level of just 16 dB, it's one of the quieter options available, making it suitable for environments where noise reduction is a priority. The fan offers two speed settings, delivering airflow rates of either 15 or 21 liters per second, providing flexibility based on your ventilation needs.

Its energy efficiency is respectable, consuming only 6.3 to 7.0 watts, which should appeal to those conscious of their energy usage. Installation is made convenient with the inclusion of both circular and square baffles, allowing for a preferred finish style. The fan's Ghost Airmovement technology contributes to its quiet performance, and its IPX4 rating ensures it is safe for bathroom environments. Additionally, the fan features a timer, adding convenience for users who want to set it to run for specific durations.

On the downside, while the fan is effective in quiet operation and energy use, its airflow capacity might not be sufficient for larger bathrooms or spaces that require more robust ventilation. The simple modern design should blend well with most bathroom décors, but those looking for advanced smart features may find it lacking. This fan is best suited for smaller bathrooms where noise and energy efficiency are the main concerns.

The Envirovent SIL100 Silent-100 is a quiet and efficient bathroom fan, making it a solid choice for anyone who prioritizes minimal sound. With a noise level of 26 dB, it stands out as one of the quietest fans in the market, earning it the Quiet Mark award in 2013, which is a testament to its silent operation. Its airflow capacity is impressive at 96 cubic metres per hour, suitable for effectively ventilating bathrooms, toilets, and kitchens.

This fan is also energy efficient, consuming only 8 watts of power, which is a plus for those looking to reduce electricity consumption. The adjustable timer feature adds convenience, allowing users to set the fan to operate for a specified time after leaving the room, ensuring continued ventilation without unnecessary energy use. Additionally, the fan's IP45 rating makes it water-resistant, which is crucial for bathroom environments.

Installation is relatively straightforward due to its compact size and standard 100mm diameter, which is compatible with most ducting systems. However, it requires a mains connection to 230/240V AC, which might necessitate professional installation if you're not comfortable with electrical work. On the downside, the fan is available in a classic white style, which might not suit all modern bathroom aesthetics. Weighing just 250 grams, it's lightweight, but this might also suggest that it may not feel as robust as some users might like. Despite these minor drawbacks, the Envirovent SIL100 provides excellent performance and noise reduction, making it a great choice for those seeking a quiet and efficient bathroom ventilation solution.

The Manrose QF100T Quiet Extractor Fan is designed for those seeking a tranquil bathroom environment. With a noise level of just 27 dB, it operates quietly—akin to a whisper—making it suitable for bathrooms and toilets where noise might be a concern. This low noise level is achieved through testing in an anechoic chamber, ensuring the fan's quiet operation under controlled conditions.

Its compact dimensions (16.3 x 11.1 x 16.3 cm) and lightweight build (621 g) make it easy to fit into most bathroom spaces without being intrusive. The fan is equipped with a timer feature, allowing users to set an operating time between 0 to 20 minutes, which is a helpful addition for energy efficiency and convenience. The inclusion of a backdraught shutter helps in preventing unwanted air from flowing back into the room.

The fan is powered by a corded electric source with low wattage (4.8 watts), making it energy-efficient. Its modern style in white complements most bathroom decors, and it comes with all necessary fixings and ducting for installation. Designed for indoor use, it's certified to IP44 for splash resistance, ensuring it can handle the humid environment of a bathroom. Potential buyers should be mindful that this product is primarily suitable for smaller spaces due to its size and features, and may not be the best fit for larger bathrooms needing higher airflow capacity.
