The Xpelair offers two speeds depending on how powerful you’d like it to be. This will vary on bathrooms size, and will have an effect on noise level. The slower the fan needs to work, the quieter it will be. The timer can range from 30 seconds – 30 minutes, again this setting will depend on how hard you need the fan to work. 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:

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. 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. Available in seven different colours, the Awenta offers an affordable option with features you’d expect. Modern looking, this extractor fan fits in well with newly renovated rooms or extensions. 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.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. Most domestic bathroom extractors attach to a 100mm hole in the outside wall. If you’re replacing a standard-sized extractor fan, this hole will already be present and you should be able to install the new one yourself. Before you remove the old fan, it’s a good idea to take a photo of its wiring for later reference – and make absolutely sure you shut off the mains power before you take the old one’s front housing off. The fan is switched on and off by means of a switch (not included in the device) being a part of the electrical installation of the building, but it will turn off after the time set by a potentiometer on the PCB has elapsed. The minimum delay is 3 minutes, the maximum - 30 minutes. Time delay adjustment is smooth.

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 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. This really is an excellent extractor that uses just 2W of electricity when running continuously and no more than 5W at full pelt. It’s also one of the most attractive models around – the fascia can be used bare or with the included white magnetic cover – and one of the very quietest. 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. 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.

Can I Collect My Order Instead?

How much extraction you’ll need depends on how large your bathroom is, how well it’s already ventilated, and how many people will be using it. As extractor fans don’t use a massive amount of power, it’s best to go for the most powerful one available within your budget. If you want further reassurance, you can also look for fans with accreditation from the Noise Abatement Society. These products will be marked with the Quiet Mark, which is given to the manufacturers of the most silent products produced around the world. 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. This model comes in four variations, each with different extras like a Timer, Pull Cord and Humidistat. The variation with a Timer and Humidistat is the most expensive option, but one well worth looking into.
