XpelairC4HTSR 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!

The actual cover is quite large but looks smart and is useful for covering up messy walls from where the duct/wiring is. Easy enough to install.It's quite quiet but this is more down to a less powerful fan and less airflow to similar fans

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

Bought 2 of these to replace 30yr old humidity controlled fans that had discoloured. They are no quieter. The cover is a nightmare to remove requiring considerable force with a screwdriver. And the controls can only be accessed by removing it.But most disappointing is that it doesn’t turn itself off - runs for 12+ hours after use. So have a shower in the evening and it runs, noisily, all night even on a warm, dry summer’s day.This is on the highest humidity setting and the shortest timer setting so no further adjustments possible.One bathroom has an isolator switch- turning this off then immediately back on stops it so the humidity has obviously reduced to the level at which it should turn off. Unfortunately our en suite has no isolator switch….

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.

It was all going so well. Quiet fan, full feature. Nice choice of covers included.Until one windy night this stupid fan flapped all night long. The backdraft flaps are very noisy. It kept me awake. I will be removing and returning immediately.Waste of time

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.

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.
