Not every 100mm bathroom extractor fan in this list was measured the same way, and that changes which number you should trust. Every listing that states a distance uses 3 metres: 25 dB(A) on the Manrose MF100T, 26.5 dB(A) on the Envirovent SIL100, 26 dB(A) on the Vents Silenta, 28.8 dB on the Airflow iCON 15 and 32 dB(A) on the CubeTECH. The Xpelair C4TSR claims 16 dB and says nothing about where the microphone was, which means it cannot be lined up against any of them. Meanwhile, the Manrose QF100T is the only fan here honest enough to say its 27 dB reading comes from an anechoic chamber — a room with no echoes, not your bathroom wall.

The airflow column is just as loose. The QF100T lists "21 Cubic Feet Per Minute", about 36 m³/h in a class where rivals quote 78 to 98 m³/h. The Hon&Guan claims 110 m³/h from a 5W motor through a 102mm duct that will not fit the standard 100mm hole. We ranked ten of the best bathroom extractor fan options on Amazon on three things we could actually check: whether the airflow and noise figures are given in units you can compare, what the fitting demands of your wall, and how the ratings split across the 1- to 5-star bars.

## The ranking

### 1. Envirovent SIL100 Silent-100 Timer Extractor Fan, 100mm

- Price: £41.99 | Amazon rating: 4.4 from 4,001 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/envirovent-sil100-extractor-fan
- Buy on Amazon: https://www.amazon.co.uk/dp/B0080XNKQ0?tag=ranked10-21

The only fan here that states both a 96 m³/h extract rate and 26.5 dB(A) at 3 metres — which is why it takes first place in this bathroom extractor fan ranking.

26 litres per second — 96 m³/h — from an 8W brushless motor, with the noise figure taken at 3 metres. In practice, that combination is why it leads. The CubeTECH moves less air (90 m³/h) and makes more noise (32 dB). The Vents Silenta matches the noise figure but gives away 18 m³/h of airflow. And Envirovent states the distance, which the Xpelair C4TSR does not.

The spigot is 99mm and projects 80mm behind the installed face, so it couples to standard 100mm ducting; the face plate is 158mm square. Eleven blades, IP45 rated — the highest water protection in this group — an adjustable over-run timer and a 2013 Quiet Mark award. Wiring needs a permanent live, a switched live and a neutral, so this is not a two-wire swap.

That said, an axial fan of this size is the wrong tool for a long duct with two bends in it. It is also not the cheapest bathroom extractor fan here: the Vents Silenta lists 78 m³/h for £26.59, and the HG Power lists 95 m³/h for £19.97. What you are paying for is the stated distance behind the 26.5 dB figure, the IP45 rating and the warranty. If none of those three matters to you, spend less.

Pros: 96 m³/h (26 l/s), the highest axial airflow in this list; 26.5 dB(A) measured at 3 metres — a distance the listing actually states; 8W brushless motor with an adjustable over-run timer; IP45 rated, the highest water protection here; 71% of its 4,001 ratings are 5-star
Cons: £41.99 is £15 more than the Vents Silenta, which lists 78 m³/h; The spec table says 26 dB while the bullet text says 26.5 dB(A); Needs permanent live, switched live and neutral wiring; Axial design loses flow on long or bendy duct runs

### 2. VENTS Silenta 100mm Extractor Fan with Run-On Timer

- Price: £26.59 | Amazon rating: 4.3 from 4,090 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/vents-silenta-100mm-extractor-fan
- Buy on Amazon: https://www.amazon.co.uk/dp/B01LXUKQ8S?tag=ranked10-21

78 m³/h and 26 dB(A) at 3 metres for £26.59 — the strongest value in the top three.

£26.59 buys 78 m³/h and 26 dB(A) taken at 3 metres, which lands within half a decibel of the Envirovent that costs £15 more. It is a bathroom extractor fan with run on timer and a backdraught shutter, and on price against delivered airflow nothing else in the top five gets close.

The listing disagrees with itself on power: the bullet text claims a 5.5W running motor, the specification table says 7W. Either way both are below the Envirovent's 8W. It is a 100mm axial unit wired live, switched live and neutral, covered by a five-year warranty — the longest in this list, against two years on both Xpelairs. The same body is sold with a pull cord, humidity sensor or PIR detector, and there is a 150mm version.

By contrast, there is one speed only and the timer triggers from the light switch, so there is no separate boost control. Anyone wanting humidity sensing has to buy a different variant. Worth noting too: on a duct run beyond about a metre and a half with a bend, 78 m³/h will not survive the pressure drop. For a standard en-suite it is the quiet bathroom extractor fan to fit. For a long roof run it is the wrong shape of fan altogether.

Pros: 78 m³/h (22 l/s) airflow for £26.59; 26 dB(A) at 3 metres, with the distance stated; Five-year warranty — the longest cover in this group; Backdraught shutter and run-on timer included; 63% of its 4,090 ratings are 5-star
Cons: Bullet text says a 5.5W motor, specification table says 7W; Timer only triggers from the light switch, with no separate boost; One speed only, and no humidity or PIR option on this exact model; 100mm axial design loses performance on long or bendy duct runs

### 3. Manrose QF100T Quiet Extractor Fan with Timer, 100mm

- Price: £30.99 | Amazon rating: 4.4 from 3,739 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/manrose-qf100t-extractor-fan
- Buy on Amazon: https://www.amazon.co.uk/dp/B00CJ8L8ZM?tag=ranked10-21

The only listing here that admits its 27 dB figure comes from an anechoic chamber.

The QF100T is the only bathroom extractor fan in this list that tells you the conditions behind its noise number: 27 dB, measured in an anechoic chamber to a recognised standard. That is more than most rivals admit. Crucially, it also means the figure is not directly comparable to the 26.5 dB at 3 metres from the Envirovent or the 25 dB at 3 metres from the Manrose MF100T.

Airflow is where the listing falls down. The specification table gives "21 Cubic Feet Per Minute" — roughly 36 m³/h — in a class where rivals quote 78 to 98 m³/h. It draws 4.8W, the lowest of any fan here, is IP44 rated and meets Part F and L, and includes an over-run timer, a backdraught shutter and turning vane technology to smooth the flow.

Even so, 21 CFM will not clear a steamy family bathroom quickly, whatever the decibel figure says. Buy this one for a small toilet or en-suite where noise matters more than speed. And expect to convert the airflow yourself — this is the only listing here that never states it in m³/h.

Pros: The only listing here that names its test conditions: an anechoic chamber; 27 dB noise figure; 4.8W power draw, the lowest in this list; Over-run timer and backdraught shutter fitted as standard; IP44, Part F and L compliant, with 68% of 3,739 ratings at 5-star
Cons: Airflow given as "21 Cubic Feet Per Minute" — about 36 m³/h, less than half of rivals; Noise is not quoted at a distance, so it is not like-for-like with the others; Airflow is never stated in m³/h anywhere in the listing; Wall, ceiling and panel mounting only, with no window kit

### 4. Manrose MF100T Inline Extractor Fan with Timer, 100mm

- Price: £62.60 | Amazon rating: 4.6 from 2,784 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/manrose-mf100t-inline-extractor
- Buy on Amazon: https://www.amazon.co.uk/dp/B01G8DM5UA?tag=ranked10-21

245 m³/h from an inline unit — two and a half times the airflow of the best axial fan here.

68 litres per second — 245 m³/h — on maximum speed, from 25W, at 25 dB(A) measured at 3 metres. Nothing else in this list comes near on airflow: the Envirovent moves 96 m³/h, the Hon&Guan 110 m³/h. Three speeds are selected by an internal dip switch.

This is an inline mixed-flow fan, not a wall grille. It sits inside rigid ducting, usually in a loft or ceiling void, and is built to hold pressure over a longer run. The motor is ball-bearing and continuously rated for 30,000 hours or three years, the unit is Class II double insulated so no earth is required, and it is BEAB and CE approved with a built-in run-on timer.

Do not buy this to fill a hole in a tiled wall — it will not fit there, and it needs access to the duct for maintenance. It also needs a permanent live for the timer. As a result, check the description rather than the specification table: that table lists the power source as "Battery Powered", the item as "Rechargeable", and names the room as "Kitchen". None of that is right for a 240V inline fan.

Pros: 245 m³/h (68 l/s) at maximum speed — 2.5x the best axial fan here; 25 dB(A) at 3 metres even at full flow; Ball-bearing motor rated for 30,000 hours or 3 years; Three speeds selected via internal dip switch; Class II double insulated, no earth required
Cons: Specification table wrongly lists "Battery Powered" and "Rechargeable"; Needs a loft or ceiling void with access to rigid ducting; £62.60, the second most expensive fan in the list; Not a like-for-like replacement for a wall grille

### 5. Airflow iCON 15 Extractor Fan, 19 l/s, 100mm Duct

- Price: £59.99 | Amazon rating: 4.4 from 1,599 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/airflow-icon-15
- Buy on Amazon: https://www.amazon.co.uk/dp/B005FPD49E?tag=ranked10-21

19 l/s at 28.8 dB measured at 3 metres, with an iris shutter that seals the duct when the fan stops.

69 m³/h (19 l/s) at 28.8 dB, taken at 3 metres, for 9.4W. In theory those numbers sit in the middle of this group — quieter than the CubeTECH and the HG Power, but moving less air than the Envirovent, the Vents or the Hon&Guan, and costing more than all three.

The selling point is the iris shutter, which closes like a camera lens when the fan stops and seals the hole against backdraughts and outside noise. Fitting takes a single 110mm core drill, wall or ceiling, and the circular design means no squaring up and little tiling damage. It arrives set up for light-switch operation, and you snap an optional module under the twist-off cover for a run-on timer, humidity sensor, PIR or pull cord. Covers are interchangeable in seven colours, and there is a three-year warranty from a brand trading since 1955.

The catch is that those control modules are sold separately, so £59.99 buys the fan and nothing else; the timer version costs more again. It also wants a 110mm hole rather than the standard 100mm, which matters if you are swapping out an existing fan. Two speeds only, set at installation, with no fine adjustment afterwards.

Pros: 69 m³/h (19 l/s) at 28.8 dB, with 3 metres stated as the distance; Iris shutter seals the duct when off, unlike louvred fans; Timer, humidity, PIR or pull-cord modules can be added later without changing the fan; Seven interchangeable cover colours and a 3-year warranty; Recessed 110mm circular fit, no squaring up and minimal tiling damage
Cons: Timer, humidity and PIR modules cost extra on top of £59.99; Needs a 110mm core drill, not the standard 100mm hole; 27 m³/h less airflow than the £41.99 Envirovent; Only two speeds, both fixed at installation

### 6. Xpelair C4TSR Simply Silent 100mm Extractor Fan, Timer

- Price: £46.99 | Amazon rating: 4.2 from 859 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/xpelair-c4tsr-simply-silent
- Buy on Amazon: https://www.amazon.co.uk/dp/B08KQBLL2P?tag=ranked10-21

Claims 16 dB — the lowest figure here, and the only one with no measurement distance attached.

The C4TSR lists 16 dB. No other fan in this list goes below 25, and the ones that do state a distance — the Envirovent at 26.5 dB, the Vents at 26 dB, the Manrose MF100T at 25 dB — are all measured at 3 metres. The C4TSR does not say how far away the microphone was, whether the reading was taken in free air, or how the AC motor was loaded. A 10 dB gap is not a small edge. It is the difference between a number you can compare and a number you cannot.

It runs two speeds, 15 or 21 l/s, selected when you install it. Power draw is 6.3W at low and 7.0W at high, against 8W for the Envirovent. There is an over-run timer and a 2-year guarantee, it is IPX4 rated, and it ships with both a circular and a square baffle so you can pick the finish. Xpelair markets the motor as "Ghost Air movement technology".

That said, buyers who want the quietest figure on paper will be drawn to the 16 dB, and buyers who want a number they can check against another fan should not be. The specification table also lists 15 l/s while the bullet text claims up to 21 l/s, so even the airflow column does not agree with itself. It is the joint-lowest rated fan in this top ten at 4.2 stars, from 859 reviews.

Pros: 16 dB — the lowest quoted noise figure in this list; 6.3 to 7.0W, among the lowest power draws here; Two speeds, 15 or 21 l/s, selected at installation; Ships with both circular and square baffles for the finish you want; IPX4 rated with a 2-year guarantee
Cons: The 16 dB figure has no stated measurement distance or test method; Spec table says 15 l/s while the bullet text claims up to 21 l/s; Two-year guarantee, against five years on the Vents Silenta; Joint-lowest rating here at 4.2 stars, from 859 reviews

### 7. CubeTECH CTQF100t 100mm Extractor Fan with Timer + LED

- Price: £37.99 | Amazon rating: 4.3 from 493 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/cubetech-ctqf100t-bathroom-fan
- Buy on Amazon: https://www.amazon.co.uk/dp/B0BBSKLH3R?tag=ranked10-21

90 m³/h and a 2-to-30-minute timer behind a 39mm white glass face plate.

90 m³/h (25 l/s) at 32 dB(A) measured at 3 metres, from 10W. That airflow is the second highest of any axial fan here, behind the Envirovent's 96 m³/h. At the same time, 32 dB is the loudest figure any manufacturer in this group is willing to attach to a stated distance — six decibels above the Manrose MF100T.

The face is white glass and only 39mm deep, so it sits flatter against a wall or ceiling than the 158mm square plastic grilles on most of the others. The over-run timer adjusts from 2 to 30 minutes, a longer range than the Xpelair LV100T's 2 to 20. There is an integrated LED light, a brushless motor running at 2,350 rpm and seven blades, and it mounts on wall or ceiling.

The listing says "almost silent" in its first bullet and 32 dB in its third. Those two claims pull in opposite directions, and 32 dB is roughly the level of a quiet conversation. It is a fair fan, not a silent one. The specification table also lists the switch type as a pull chain and the controller as a remote, neither of which matches a fan sold with a light-switch timer. If you want a genuinely quiet bathroom extractor fan, look at the Manrose QF100T or the Vents Silenta first.

Pros: 90 m³/h (25 l/s) from a 10W brushless motor; Over-run timer adjustable from 2 to 30 minutes; 39mm glass face plate, flatter than most plastic grilles; Integrated LED light and a seven-blade, 2,350 rpm impeller; 70% of its 493 ratings are 5-star
Cons: 32 dB at 3 metres — the loudest stated figure in this list; First bullet says "almost silent", third bullet says 32 dB; Spec table lists a pull chain and a remote, not the timer control; 493 ratings is the smallest review base in the top seven

### 8. HG Power 100mm Extractor Fan, No Timer

- Price: £19.97 | Amazon rating: 4.4 from 272 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/hg-power-100mm-extractor-fan
- Buy on Amazon: https://www.amazon.co.uk/dp/B0DCGK8CP6?tag=ranked10-21

£19.97 for 95 m³/h — within 1 m³/h of the Envirovent, with no timer at all.

95 m³/h at 30 dB for £19.97. That airflow is within 1 m³/h of the Envirovent, which costs more than twice as much. There is no timer, no humidity sensor and no pull cord, which is precisely why it is cheap — switching is done at the wall or the light switch, and nothing runs on after you leave the room.

The motor is a double ball-bearing unit with copper coils, drawing 10W at 2,550 rpm. The housing is PC+ABS composite rather than plain ABS, which the listing says resists moisture better, and the unit is IP44 rated. It mounts on a wall or ceiling and the surface wipes clean. It carries CE and RoHS marks.

Without a run-on timer, though, this fan stops the moment the switch does, and the last of the steam stays where it is. That is fine in a small toilet and less fine in a shower room. At 272 ratings it has the second-smallest review base here, so the 4.4 stars rests on far fewer buyers than the Envirovent's 4.4 from 4,001. If you need a bathroom extractor fan with timer built in, this is not the one.

Pros: 95 m³/h, within 1 m³/h of the £41.99 Envirovent; £19.97 — the cheapest fan in this list; 10W double ball-bearing motor with copper coils, 2,550 rpm; IP44 rated in a wipe-clean PC+ABS housing; 74% of its 272 ratings are 5-star
Cons: No timer, humidity sensor or pull cord — it stops with the switch; 30 dB with no stated measurement distance; 272 ratings, the second-smallest review base here; Wall or ceiling mounting only

### 9. Hon&Guan 102mm Extractor Fan with Timer, 110 m³/h, 5W

- Price: £29.74 | Amazon rating: 4.2 from 167 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/hon-guan-102mm-extractor-fan
- Buy on Amazon: https://www.amazon.co.uk/dp/B0GYCKRB84?tag=ranked10-21

110 m³/h from a 5W motor — and a 102mm duct that wants a 105mm hole.

The headline number is 110 m³/h, the highest airflow in this group, delivered from a 5W DC motor. The nearest rival is the Envirovent at 96 m³/h from 8W, then the Vents Silenta at 78 m³/h. That ratio is why a lesser-known brand sits above three established names.

A brushless DC motor makes 5W plausible at that flow; the AC motors in this class typically draw 8 to 13W. There are five timer settings — 1, 5, 10, 15 or 30 minutes — and the memory holds your choice after a power cut. The backdraught shutter opens to 85 degrees, the cover is magnetic and snaps off for cleaning, and the unit is IP64 rated, the highest water protection in this list, with a two-year warranty.

The catch is the duct. It is 102mm, not 100mm, and the listing states that installation needs a 105mm hole. If you are replacing a fan on an existing 100mm duct, or you have already core-drilled at 100mm, this will not drop in without opening the hole out. At 35 dB it is also the loudest figure quoted here, and again with no stated distance. High flow, yes; quiet, no.

Pros: 110 m³/h — the highest airflow in this list; 5W brushless DC motor, a third of what comparable AC fans draw; Five timer settings (1, 5, 10, 15, 30 minutes) held in memory; IP64 rated, the highest water protection here; Magnetic snap-off cover for cleaning, plus a 2-year warranty
Cons: 102mm duct needs a 105mm hole, not the standard 100mm; 35 dB is the loudest quoted figure here, with no distance given; 167 ratings — the smallest review base in the top ten; 4.2 stars, the joint-lowest rating in this list

### 10. Xpelair LV100T Low Voltage Extractor Fan with Timer, 12V

- Price: £83.99 | Amazon rating: 4.6 from 129 ratings
- Full review: https://www.ranked10.co.uk/home/best-bathroom-extractor-fans/xpelair-lv100t-low-voltage-fan
- Buy on Amazon: https://www.amazon.co.uk/dp/B0036PQIBG?tag=ranked10-21

12V SELV, a remote transformer and a 2-to-20-minute timer — the only fan here rated for a shower zone.

This is the only 12V safety extra-low voltage fan in the list, and the only one supplied with a remote transformer. It draws 13W, the highest power consumption here, and Xpelair publishes no airflow figure and no noise figure at all. At £83.99 it is also the most expensive bathroom extractor fan in this top ten.

The reason to buy it is the wiring, not the numbers. A 240V fan inside a shower cubicle or within reach of a bath normally falls foul of the wiring regulations; a 12V SELV unit fed from a transformer outside the zone does not. The timer runs from 2 to 20 minutes and is triggered by a remote switch, usually the lighting circuit. It comes with a universal mounting kit, conforms to Building Regulations Part F1, and can be wall or window mounted.

Even so, the transformer has to live somewhere accessible and dry, and you have to wire both it and the fan. There is no airflow figure to check and no decibel figure to compare against anything else in this list, which means you are buying on the low-voltage specification and the brand rather than on measured performance. At 129 ratings it is the least-reviewed fan here. If you do not actually need 12V, the mains fans above are cheaper and far better documented.

Pros: 12V SELV with a remote transformer — safe for shower and bath zones; Timer adjustable from 2 to 20 minutes, triggered by a remote switch; Universal mounting kit included; Conforms to Building Regulations Part F1; 4.6 stars, the joint-highest rating in this list
Cons: £83.99 — the most expensive fan here, with no airflow figure published; No noise figure at all, so it cannot be compared with the rest of the list; 13W, the highest power consumption here; 129 ratings, the smallest review base, and the transformer needs its own dry location

## Verdict

For most homes, the Envirovent SIL100 is the bathroom extractor fan to pick: 96 m³/h, 26.5 dB measured at 3 metres, 8W and IP45, and it is the only fan here whose quietness claim comes with a stated distance and a Quiet Mark award. If £41.99 is more than you want to spend, the Vents Silenta does 78 m³/h at 26 dB for £26.59 with a five-year warranty, and it is the better value of the two on paper — provided you accept that its own listing quotes 5.5W in one place and 7W in another. If your duct run is long or bends more than once, no axial fan here will hold its rated flow, so go straight to the inline Manrose MF100T at 245 m³/h and 25 dB, and accept the loft access it needs. In short, match the fan to the hole in your wall before you match it to the decibels: the Hon&Guan wants 105mm and the iCON 15 wants 110mm, and neither drops into a standard 100mm core. Whichever bathroom extractor fan you buy, check the measurement distance behind the noise figure — that is what separates a real comparison from a marketing number.
