Extractor fan for Bathroom

Forget the extractor fan, noisy, causes massive draughts throughout your home, etc, etc.  Get a dehumidifier.  Bye bye condensation & bye bye mould.  If I had realised how great it was I would have bought one with a humidity cut off - as in get down to 40% & turn itself off.  When this one breaks that is what I will be getting.

But you can't permanently plug a dehumidifier in, in your bathroom. You'd have to use an extension lead (or a conveniently  located plug socket) to enable you to position it in the room. Bathroom fans that come on when the humidity is over a certain level take up much less space and can extract for as long as necessary. The fans we bought were well over £100 each, but worth every penny.

We also have Meaco dehumidifier (with a cut off) which is fantastic when drying laundry inside and reducing general humidity in the flat - but it needs to be stored somewhere, emptied and is cumbersome to move around - it didn't really properly address the bathroom humidity problem either - since the fans went in we've used it pretty rarely too.

Hi thanks for that.
My current cheapo  extractor fan comes on when the bathroom lights are turned on and is vented outside.
I presume the Xpelair Premier CF20T I can just do the same with and use the original mains wiring that goes to the existing fan or would I need a separate switch?
Thanks

If your existing one runs on after you have turned off the light, it seems like you have the separate supply required and yes, you use the same switch.  If you click on the link I provided, you can see the wiring schematics for the various types.

With persisting condensation, it's a sign that the room is cold.  You may find it helps to pre-heat the room well before showering as warm walls, ceiling, etc will help the condensation to evaporate and dissipate through the fan or open window.
