As standard, the Envirovent has an extraction rate of 26 litres per second which is substantially more than the Xpelair above – this is the reason the latter is slightly quieter. Vent-Axia has really pushed the boat out with this brand-new model. Aside from shifting up to 39l of damp air per second, this bathroom extractor comes crammed with more sensor tech than any other model on the market. In fact, it has a sensor for everything, even odour. Yes, that’s right, when this clever little air mover detects a nasty smell, it either switches itself on or, if already running, speeds up the fan, returning the bathroom to its original sweet-smelling scent in a thrice. Extractors come in two sizes: 100mm/4 inches and 150mm/6 inches. In most cases, the 4-inch fan will remove moist air well enough to keep the bathroom smelling fresh and be less susceptible to mould. The only reasons you would need to consider a 6-inch extractor fan is if:

Recorded at 26 dB, it’s on par with the Envirovent and louder than the Awenta, although the Awenta offers extraction of less litres per second. So, if you have a bigger bathroom or condensation is a problem, it might be better you go for a slightly louder model that has more power. This is the cheapest fan we’ve tested, and it holds up well against the competition. Granted, it has less features than others (no timer or PIR) so if those are essential then this isn’t the fan for you.

The Xpelair C4HTS is a terrific extractor fan choice, coming in at 20 dB. Advertised at 16 dB we believe it’s closer to 20 dB, which is still the quietest we’ve tested. You do have the option of turning it off, but if you allow moisture to build up for a long time, the fan may struggle to get rid of it all by the time you turn it on. If your fan has a humidity sensor, you may not be able to turn it off which could ruin your chance at a peaceful soak.

There aren't many silver extractor fans on the market so it's great that the one that is, is a really good one! The EnviroventSIL100ST delivers on every front: It's really powerful - delivering 95m3/hr air flow, virtually silent - operating at just 25dB(A) and energy efficient - consuming just 8w! ..and on top of all that it looks great in a satin chrome finish.Our images show the satin silver /chrome effect as it appears in different lights from varying angles. Each extractor fan in our list is best for a different purpose. The Xpelair C4HTS is by far the quietest coming in at an incredible 20 dB (although advertised at 16 dB). Slightly harder to install than the other three, make sure you read the instructions carefully. Humidity extractor fans can be very effective in reducing excess moisture in a room or area. They work by drawing in humid air and expelling it outside, which can help prevent mould growth, reduce the risk of respiratory problems, and improve overall air quality. However, the effectiveness of a humidity extractor fan depends on several factors, such as the size of the fan, the size of the room, and how often the fan is used. It is also important to properly maintain the fan, including regularly cleaning the filters and ensuring that it is installed correctly. Overall, humidity extractor fans can be a useful tool in managing humidity levels, but it is important to do your research and choose a high-quality fan that is appropriate for your specific needs. The Blauberg 100 Quiet Style TH is the perfect solution for those looking for a powerful and stylish fan that won’t break the bank. German-engineered for quality and reliability, this fan boasts a powerful airflow extraction rate of 27 litres per second, making it perfect for use in toilets and bathrooms. Yes, it is highly recommended to get a bathroom fan with a humidity sensor. This type of fan can detect the level of humidity in the bathroom and automatically turn on and off accordingly. This is important because high humidity levels can cause mould and mildew growth, which can be harmful to your health and damage your bathroom. A bathroom fan with a humidity sensor can also help reduce moisture buildup, prevent condensation on mirrors and walls, and improve air quality. In addition, this type of fan is convenient and energy-efficient, as it only runs when needed. Overall, investing in a bathroom fan with a humidity sensor is a smart choice for maintaining a healthy and comfortable bathroom environment.Even if your fan doesn’t wake anyone, it might simply be an annoying sound. If you’re unwinding in the bath after a long day, the last thing you want is the drone of the extractor fan running. The Envirovent SIL100T is probably the best overall extractor fan choice for a standard bathroom. Coming in white only, it should suit most bathrooms, but leaves it slightly limited when dealing with bathrooms of different colours. The Envirovent SIL100T is a great all-round option and the most well-known brand. Reliable and well-built, this fan is easy to install and will work without you noticing it too much. A humidistat is a device that measures the level of humidity in the air. When it is installed on an extractor fan, it helps to regulate the amount of moisture in a room or space by automatically turning the fan on or off depending on the humidity level. When the humidity is high, the humidistat will activate the fan to remove excess moisture from the air, which can help prevent mould and mildew growth, reduce odours, and improve indoor air quality. The humidistat also helps to save energy by only running the fan when it is needed, rather than constantly running it at full speed. Overall, the addition of a humidistat to an extractor fan can help to create a more comfortable and healthy living environment. Should I get a bathroom fan with a humidity sensor? The precise duration of the overrun is normally configured during installation, with most fans offering a range between 30 seconds and 30 minutes. You might as well tend towards the latter end of the scale as the cost is very low: on average, a fan like this uses around 8W.

Depending on the schedule of other members of the household, it could also wake you up. If you have a spouse or flat mate that works late shifts and likes to shower when they get in at night, then a noisy fan running at all hours could disturb your sleep. A PIR motion sensor starts the fan if you move within 4 metres, so for my smallish bathroom it is always on. Can be a pro or a con depending how you see it. Until you have one, it’s hard to explain the difference a silent bathroom extractor fan will make. It sounds silly, but removing unnecessary noise really does make a difference, especially when trying to unwind from a hard day.This could be a good combo with the overrun timer; if there’s still a lot of moisture, even after the overrun, the humidity sensor will activate and complete the job. Do be aware, though, that the sensor won’t work as well if it’s dirty. Wipe it down every couple of months to ensure it works as intended. Two speed options are available of 15 and 21 litres per second. 15 is the lowest extractors fans should be, so you have the option of increasing to 21 if you need more power or have a bigger bathroom. An overrun timer gives it time to complete the job. You can set how long it runs for when the fan is installed, but most models offer settings from 30 seconds to 30 minutes. If you’re going to use this feature, it makes sense to leave it running for as long as possible to make sure it removes as much humidity as possible.
