Why do I need a bathroom extractor fan?

Bathroom extractor fans remove moist air and unwanted smells from your bathroom. When you run hot water in a bathroom, moist air fills the room. If this air is not extracted quickly, it can cause aesthetic and structural damage to your bathroom’s walls and/or ceiling. For this reason, it is now a legal requirement to have a sufficiently powerful bathroom extractor fan.

Building regulations

Building Regulations guidelines for England and Wales state that a bathroom fan must extract air at a rate of 15 l/sec (54 m3/hr). If your bathroom is an internal room with no opening windows that allow rapid ventilation, your extraction fan must also have a 15 minute overrun timer.

Best Bathroom Extractor Fan: Things to consider

Overrun Timer: This is a feature that allows the fan to continue running after its been switched off. Bathrooms without external windows (that allow rapid ventilation) are legally required to have an extractor fan with an overrun timer of 15 minutes. This is to allow sufficient time for an extractor fan to rid a bathroom of moist air.

Back-draught Shutter: This prevents external air/wind coming through your ventilation duct. An important feature for winter months when you want to keep your house properly insulated and warm.

Decibels: How loud is a bathroom extractor fan? Pay particular attention to this feature if you’re installing a bathroom extractor fan to an ensuite.

Power Usage: How much power is consumed by an extractor fan? A good way to measure if a fan is efficient is by looking at its extraction rate (below) compared to its power usage. Logic dictates that higher power usages demand better extraction rates.

Extraction Rate: This is one of the most important features you can look at. If you’re installing a bathroom extractor fan in the UK, then it needs an extraction rate of at least 15 l/sec (litre of air per second). Note that the fast the extraction rate, the faster your bathroom with be drained of moist air or bad smells.

Humidistat (Humidity Sensor): This is an intelligent feature that automatically switches on the extractor fan when it detects certain levels of moist air. Likewise, it will automatically switch off when the levels of moist air falls below a certain level.
