Xpelair C4HTSR 4" Simply Silent Contour bathroom extractor fan with humidistat and timer, plus choice of square and round baffles, White, 240V

I installed the Xpelair C4HTSR 4-inch extractor fan in my bathroom, and it has been working perfectly. It’s quiet, even when running on the higher setting, and does a great job of clearing steam and moisture quickly. The humidity sensor is a great feature, as it automatically turns on when needed, which is really convenient.Installation was straightforward, and the adjustable timer makes it easy to customize how long it runs after the room is used. It also looks sleek and modern, blending in well with the bathroom decor.Overall, it’s a reliable and efficient fan that does exactly what it’s supposed to. Highly recommended!

Easy assembly, fit well in my toilet and looks great with my choice in square or circle cover. Very functional and very quiet.

The extractor fan was reasonably easy to fit and runs fairly quietly.My main disappointment is that the humidity sensor adjustment doesn't seem to make any difference and it runs for 6 to 12 hours plus after having a shower (even with the window open now the weather is warmer).I have adjusted the timer so it only runs for a few minutes after manually turned on and off.The other adjustment doesn't seem to make any difference to the sensitivity to humidity and always is too sensitive. The fan will automatically come on within a few minutes of someone just being stood underneath the fan!I fitted the fan a few months after buying it, so unable to return it as faulty.There is at least one other review that seems to suggest the same fault.I will try talking to Xpelair customer service to see what they suggest as it's supposed to have a two year warranty.

This replaced a cheaper 100mm fan which ran off an isolator switch. This new fan is running off of the same switch permanently on, with the fan powering on when the room has high humidity - perfect for our use case where we want it to be able to handle for humidity without our intervention.Has two semicircle flaps to prevent backdraught which work reasonably well, a fixing-less clamp arrangement on each side, and two fascias. Not the easiest mechanism to remove the casing to get to the controls - these could be placed somewhere accessible - but otherwise a good investment so far.

Do not buy this, the humidistat or timer does not operate properly. Sometimes it turns off, ither times uts on xonstantly so has to be switched off from mains. I have 2 of them and both have this issue. It is also very loud. Get vent axia, much better.

Likes:Simple to install as it was a like-for-like replacement.Quiet when running so why 3* for noise level. Has already started rattling against the side walls. Removed the cover and "twiddled" the fan. Replaced the cover and the noise has gone away. Had the same fault as the previous one but it had been in for 3 years.Dislikes.Unable to fix the "square cover" as supplied as unable to remove the circular one, no matter how hard I try. Applying any additional force will most likely break it.The fan sometimes stays on and does not go off even when the bathroom is fully clear of moisture. Consequently, we have to turn it off at the isolator switch. Switch it off and on and it works perfectly again.

Quiet and easy to fit. The overrun and humidistat are good features and can be adjusted to your needs. This was a good price for the features.

This was a great fan powerful, very quiet. Instructins could be improved as well as taking front off.We had it working for a four days and already. Made a big difference to our bathroom.. Reduced dampness and feels cleaner. Overlall very pleaseed.
