One thing that I do advise is to go for humidstat extractors with a
pull cord on to the timer as well. This enables extraction when the
air moisture level gets too high, avoids the irritation of the fan
coming unnecessarily when you switch the light on, but does allow you
to blow out the smells when you need to.


I am of the opinion that average priced humidistat fans are a waste of
time - the first thing to go is the humidistat!
