Xpelair DX100H 12W Axial Bathroom Extractor Fan with Humidistat & Timer
Good, but not great
I fitted this into a bathroom as the house was starting to get a bit damp in the run-up to winter.
This unit is intended to be permanently live (not switched off a light switch); it decides when the humidity is too high and cuts in and out as it needs to. The advantage of this is the fan isn't running at times it's not needed - such as when you go to the loo in the middle of the night.
There are two controls: one for the humidity trigger level, and the other for the timer. The manual says the timer is adjustable so that you can set how long it stays on if connected to a switch (in which case it will turn on automatically when the switch is turned, then turn off after the timer expires or when the humidity falls below the threshhold, whichever is longer). Note that if you set it up like this, when you turn the light switch off again, the fan will NOT stay on - there is no facility to connect both permanent and switched lives.
I used the factory settings but found the fan was cutting in and out too often. I turned up the timer potentiometer to stop it cutting out so quickly; although the manual doesn't seem to say this is what it's for, it appears to have worked. It's not obvious which potentiometer is which but they are labelled on the PCB if you look carefully.
Other reviewers are saying this fan is quiet, but mine isn't. It's averagely noisy, but nowhere NEAR as quiet as some of the whisper-quiet fans which are becoming fashionable at the moment. If you want a quiet fan, don't buy this one.
For the price you get a well-built unit, and many of the fixings you're likely to need to mount it. There are cheaper humidistat fans, but the reviews of the others don't inspire me with confidence.
Apart from the noise, the other disappointment is that the throughput doesn't seem any more than adequate. I had hoped for a bit more oomph.
Backdraft protection is an added bonus and worth having - it helps stop the shutters on the vent from flapping in the breeze, and avoids cold air blowing back in through the fan.
For the money this is a good buy, but if you want a quiet, powerful fan be prepared to pay more.
I haven't had it long enough to know if it's reliable so it gets a standard 3 stars; however, the light on mine doesn't appear to work.
If installing this in a location containing a bath or shower, be aware that it may be notifiable work (depending on exact location), so may need to be done by a registered electrician who can certify it and notify Building Control. It will also need a suitable isolator (such as switched fused connection unit).

Quiet effective fan
This fan is so quiet I cannot hear if it goes on when having a shower. Has made a big difference in clearing bathroom of steam and reducing mould etc.
If fitting through brickwork you will find the need to buy longer length of pipe- screwfix stocks this also- costs less than Â£2.
I fitted mine on ceiling above bath and it works great- should have got one years ago.
