Review: Very effective and quiet too, but beware of air depletion in the room! - Happy days I've found this extractor fan when was looking to replace an old one in the bathroom, that was as "effective" new - same as dead. After testing one - got myself a second one. Good stuff: 1. It is easy to install, no rocket science, most people will be able to fit it with a bit of attention. Obviously I won't recommend self-install if you are not much into safety (cutting electricity safely and not working with live wires (!) or just don't feel comfortable to do so. 2. It's quiet indeed. No, don't expect it to be completely silent as it's simply impossible for something that has meaningful extraction power, which I bet we all need from an extraction fan :). But it is not loud! I am a light sleeper and can definitely fall asleep with it working right against the wall. 3. Effective and extracts decent amount of moisture! I definitely felt a big difference here in comparison with the old one. Now, I'm not taking a shower anymore in a cloud of fog and my fire alarm in landing does not go off once I open the door after showering (because of excess moisture rushing to it). Considering it also consumes just 8 watts - yes please. That's another reason why I've got two of them. TO NOTE: - Beware of air depletion (make-up air)! If something is extracting air - there has to be a replacement of air coming from somewhere. So if you have everything tightly closed, doors, windows, etc. - eventually you get reduced extraction flow and correspondingly efficiency. So if possible, consider not closing the door fully, or leaving the window slightly open. This by the way applies to any extractors and is just a showcase that this one actually has decent (96 cubic meter/hour (!) extraction power not just on paper! - If it exits in your loft or attic - make sure it goes through a pipe straight outside, through the roof or whatever setup you have. Don't leave it just like that, trust me, if it sucks air from your bathroom - it will fill effectively with moisture any room to which it connects :) you won't want clear bathroom but an attic full of mould. Beside all above, it looks good, feels sturdy for what it is and despite maybe not being the cheapest - provides great value for your money. Recommended it to my friends and can responsibly recommend it to you. Hope it helps. Stay well & Cheers!

## Questions & Answers

**Q: Timer function appears to have stopped working, continues to run after it is switched off and after the time delay set on the timer. Any suggestions?**
A: I have this problem, but it has never turned off!!?

**Q: Is it wired to the light and has a time delay when light switched off**
A: Yes it is wired to the light and the timer delay can be set for up to 30 mins.

**Q: There seems to be some confusion over the back draught shutter, is there one supplied or not please?**
A: There is a backdraught shutter supplied, although I would prefer to call it a thin piece of plastic, an after thought which is connected to the rear of the fan. I would recommend buying a separate backdraught shutter. I brought one which was a plastic spigot with a rubber shutter, which fits inside the ducting. This does not make any noise when it is windy outside.

**Q: Where is the item**
A: That presumably is a question for Amazon.

### ⭐⭐⭐⭐ It's good, but it's not silent.
*by C***S on 16 May 2024*

I have an ensuite bathroom with no window. Which is therefore prone to condensation and of course smells tend to linger....! The extractor in situ wasn't really pulling its weight, so I spent some time researching the options. This one appeared to offer a good balance between performance and cost, and to be fair it does. It's definitely shifting more air and moisture - I can feel a stronger flow at the duct exit point outside, and the walls and mirror both clear more quickly than in the past. And I'm pretty sure that smells are shifting more quickly too. I think it's a good buy, but it's no quieter than the old one. To be fair it's not at all noisy - but it's not silent. It was also very simple to fit, removal and replacement took about 15 minutes. I definitely recommend it.
