What does a bathroom extractor fan do?

Bathroom extractor fan and ventilation fans help to remove the moisture or humidity in the air after a shower or bath caused by steam. This keeps mildew from forming in the bathroom. Bathroom extractor fans also help remove any unwanted odors.

Bathroom Extractor fans options. Many brand of extractor fans come with options or add-on modules to give additional features. Standard bathroom extractor fans offer a standard on/off option controlled by a separate switch, pull cord or by the light switch. Timed or overrun fans offer the option for the fan to continue to run for a set period of time after the on/off switch is put in the off position. Humidity controlled bathroom extractor fans switch on automatically when the room humidity reaches a set level.
