Best Bathroom Extractor Fan 2026: 10 Ranked, and the 16 dB Claim That Isn't Measured

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.

£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.

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.

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.

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.

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.

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.

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.

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.
