Review: Performs well & has a tidy finish - Lot's of research lead to this product. It's not silent (in the high speed mode at least) but is much quieter than the old unit. The advantage of humidity switching ensures that most bathroom events are completed without triggering the fan. Use of a shower or bath will trigger the unit. The other advantage here is that you can set a relatively short run time, as once running, until the humidity drops below your chosen level the timer is not triggered & the fan continues to run. Fit & finish are excellent, instructions simple & swapping the old unit easy. Whilst these things couldn't be described as pretty, not seeing all the dirt in the front grill is another nice touch.
Review: It’s works and it’s quiet! - This was an easy fit in an newly fitted en-suite. I Google what the building regulations were and after going through many nice looking fans this one fitted what I needed. It arrived quickly and the plumber and electrician fitted it within the week. It can be fitted with a different shaped front as it comes with a couple and the important bit for me was that it can remove 25ltrs or 15ltrs of steam a second and it runs for 15 minutes once the shower is switched off as needed with the building regulations for en-suite bathrooms / shower rooms. And excellent piece of kit and I need four more and I will be buying these

### ⭐⭐⭐⭐ Quiet fan, does the job but do read the instructions closely.
*by R***4 on 28 June 2018*

The fan is very neat and works well. I have dropped a star as the instructions are not perfect and there were issues in the installation, see below. The instructions are the usual 40 page multi-lingual tome with 4 pages of illustrations and 4 in English which relate to the illustrations. I got the local handyman to install it as a ceiling fan to replace the previous wall mounting. He was unfamiliar with the model and missed an essential item in the instructions - I had to refit everything once he had left. (First lesson - read the instructions yourself and do a complete dry assembly) The square baffle plate over the fan has to be set parallel to the wall or square to the ceiling. To do this Xpelair have a raised line on the motor plate marked LEVEL. He had not spot the need to Level (wall fitting) or align (ceiling fitting). (Second lesson) To aid proper fitment I highlighted this line in pencil and a similar line on the ceiling. When fitting I aligned the two. Once secured I copied the wiring for there previous fan - grey to T, black to Neutral and brown to Live. Once switched on 'nothing' happened as there is no test mechanism to test the installation, the only way is to run the shower and increase the humidity. Once we got it 'working' it became apparent there were issues that I don't need to detail except to say the fan would not stop. After trying various options I contacted Xpelair. They advised that I switched two wires over. This improved matters but was not quite right. I then did a further swap and it now all works. As I had switched the timer to minimum and humidity stat to max I now need to reset these to better values. Third lesson, do not fit the fan cover until you are satisfied that the humidity stat kicks in at the right level and that the over run timer is long enough. It would be very useful if you had a humidity sensor so you could set things up. (I have). Once everything was setup and running we had the option to set the fan speed from the default Low Speed to High Speed by moving a jumper. In high there is a clearly audible rush of air through the fan (I haven't tried with the baffle plates on) At low speed the airflow is still audible in the bathroom but there is no sound outside the room. In conclusion, excellent support by Xpelair but installation, while not difficult, requires a bit more care than a simple circular mount timer fan. We ordered a second for the other bathroom. With prior experience the old fan was out and the new in in well under an hour. The wall fitting highlighted another problem. The previous fan power was on the left, the Xpelaire input is on the right. I had to install the fan upside down with the logo also upside down. Excellent fan but not 5* for the issues listed.
