Rank #2 in Best Bathroom Extractor Fan 2026: 10 Ranked, and the 16 dB Claim That Isn't Measured
VENTS Silenta 100mm Extractor Fan with Run-On Timer
Price and rating as shown on Amazon when we collected them. Both change.
The VENTS Silenta 100mm is a £26.59 bathroom extractor fan with a run-on timer and a back draught shutter, finished in brilliant white and rated for wall or ceiling mounting. It sits at number two in our guide to 100mm bathroom fans, with 4.3 out of 5 from 4,090 ratings. Its listing quotes 78 m3/hour of airflow at 26 dBA, and — unusually for this list — it says the noise was measured at 3 metres.
That distance matters, because it is the whole point of this guide: these adverts are not measured the same way, so the bigger number is not automatically the better fan. The Silenta names its distance, unlike the fan in this list that claims 16 dB without saying where from. But its own copy does not agree with itself on power: one bullet claims 5.5 W running, while the spec table lists 7 watts. Everything on this page comes from the Amazon listing for the VENTS Silenta 100mm, not from any test of ours.
