Buying A New Bathroom Extractor Fan? We Can Help You Make The Right Choice

Best bathroom extractor fan

Looking for the Best bathroom extractor fan? Check out our guide below and you’ll be well-placed to select the correct one for your needs.

It’s not a luxury to have a bathroom extractor fan; it’s a necessity.
It removes moisture from the air after a shower or bath, which could otherwise cause long-term harm, especially if your bathroom lacks an outside window.
An extractor fan is also a legal requirement if you plan to rent out your home.

However, with literally hundreds of different bathroom extractor fan types on the market, how can you choose one?
We spoke with a professional builder, who stated that all bathroom extractor fans perform the same basic function.
The key difference is that low-cost devices are more likely to break down and are louder.
As a result, it’s recommended that you always choose for a reputable brand and avoid the cheapest options.

Here’s our advice to picking the right bathroom extractor fan, as well as our picks for high-quality extractors that are economical, simple to install, and effective at removing stale air.

What factors should you consider while selecting a bathroom extractor fan?

What are the characteristics of an bathroom extractor fan that I should search for?

The average household bathroom extractor fan moves roughly 21 litres of air per second, which is sufficient for a medium-sized bathroom or shower room.
Look for a model with an overrun timer, which keeps the fan spinning for a certain period after you’ve shut it off, to ensure the room is well ventilated.

The exact time of the overrun is usually set during installation, with most fans allowing for a range of 30 seconds to 30 minutes.
You might as well go for the lower end of the range because the cost is so low: a fan like this uses about 8W on average.

A backdraught shutter is included with most bathroom extractor fans to prevent cold air from flowing in from the outside.
Windy circumstances can cause the shutter to clatter against the wall, so if your outlet is exposed to the weather, it’s probably best to leave it off.

Finally, if you (or anyone else in the house) is worried about forgetting to turn on the bathroom extractor fan, look for one with a humidity sensor.
When the amount of moisture in the air reaches a specific level, the bathroom extractor fan will automatically turn on.
However, this sensor may require cleaning from time to time if dust or grime accumulates, as this would reduce its efficiency.

What about the sound?

In a poll conducted by ventilation company Vent-Axia, 40% of respondents indicated that a noisy bathroom fan had woken them or their children up in the middle of the night.
Even the cheapest fans are normally extremely silent right out of the box, but as the motor bearings wear out – which happens after roughly two years with low-end models – the blades can start to oscillate against the main housing, causing an irritating noise.
A higher-quality bathroom extractor fan should last longer, but if you prefer quiet, you’ll need to fix or replace your fan at some point.

How do you fit a bathroom extractor fan?

A 100mm hole on the outer wall is required for most household bathroom extractor fans.
This hole will be there if you’re replacing a standard-sized bathroom extractor fan, and you should be able to install the new one yourself.
Take a photo of the old fan’s wiring for future reference before removing the front housing – and make sure you turn off the mains electricity before removing the old one’s front housing.

If you don’t already have a bathroom extractor fan, you’ll need to hire a professional to dig the hole and run the wires.
You must use a low-voltage SELV fan with a transformer or an AC-powered model that is IPX5-certified if you wish to put a fan in Zone 1 (the area within a shower or 2.25m above a bath) or Zone 2 (60cm from Zone 1).
Although the majority of our suggestions are intended for use outside of Zone 2, the layout of your bathroom may limit your alternatives.
