2. Greenwood CV2.1HT: Ultra-Silent Continuous Option

As the upgraded replacement for the now discontinued CV2GIP, the CV2.1HT is the quietest extractor fan available at a mere 7.9dB(A) in low-speed mode (up to 10.1dB overall)—even quieter than its predecessor. Delivering 21l/s (75.6 m³/h) with ultra-low 0.54W continuous power, it features SMART humidity sensing for automatic adjustments, a built-in timer with overrun and three speed settings for tailored ventilation.

3. Vent-Axia NBR: Lowest Trickle Noise

The Vent-Axia NBR edges out as the quietest extractor fan in continuous trickle mode at an astonishing 7.4dB(A)—virtually inaudible—ramping to 34.3dB only on boost for 25l/s extraction. This dMEV model shines with ambient-sensing humidistat that auto-boosts on rising humidity, optional "comfort control" to delay activation (e.g., for quiet nights), and ultra-efficient 0.08 W/l/s SFP for minimal energy use. It's wall/ceiling mountable with a slim profile and is backed by a 7-year warranty. SAP PCDB listied, it's ideal for eco-conscious installations and is compliant with 2021 Part F and L regs for low-carbon homes.

4. Vent Axia Silent Fans VASF100: Versatile & Efficient

The VASF100 range, often called the original “Silent Fan,” remains one of the quietest traditional bathroom extractor fans, delivering just 11.8–12dB(A) at a tiny 2.7-4.8W while pulling up to 23l/s on boost. IPX5-rated for safe Zone 1 installation, it offers a choice of basic, timer, and humidistat+timer models, all with an easy-clean fascia. Perfect for small to medium bathrooms that need powerful yet almost inaudible intermittent ventilation rather than continuous dMEV running, it’s still the benchmark most competitors try to beat more than a decade after it launched.

5. National Ventilation Monsoon MONS100T: Balanced Power

The National Ventilation MONS100T delivers a robust 27l/s (97 m³/h) extraction rate at a hushed 25dB(A) measured at 3 meters, powered by an energy-efficient 7.5W motor that keeps running costs low while meeting Building Regulations Parts F and L for effective moisture control in mid-sized bathrooms.

IP45-rated for safe Zone 1 use (with a 30mA RCD in splash areas), it features a customisable overrun timer adjustable from 2–30 minutes, an integrated spirit level for precise leveling during wall, ceiling, or window mounting, and a larger terminal block for hassle-free wiring, all housed in durable UV-resistant ABS plastic to prevent fading or degradation over time. With special airflow vanes that minimise turbulence for even quieter operation, a built-in backdraught shutter to block drafts and a 5-year warranty, it's an ideal choice for family bathrooms needing reliable, no-fuss ventilation without compromising on silence.

6. Airflow QuietAir QT100: Sleek & Low-Maintenance

The QT100 series stands out as a sleek axial fan that's QuietMark certified for whisper-quiet operation at just 25dB(A) on low speed, delivering two-speed extraction of 21–25 l/s (75–90 m³/h) with an energy-efficient 5–9W motor that handles up to 12m of rigid ducting while complying with Building Regulations Part F.

IP45-rated for safe Zone 1 installation (with RCD protection), it features an integral flow straightener and backdraught flap to prevent drafts, and long-life ball bearings rated for 40,000 hours, with models like the QT100T adding a 2-minute delay-on timer and adjustable overrun (6–21 minutes) to eliminate startup noise, plus a Room Refresh interval option (every 8–24 hours). For automatic control, opt for the QT100HT variant with its adjustable humidistat (65–90% RH) that triggers boost extraction during steamy conditions, all backed by a reliable 3-year warranty and available in modern black finishes to blend seamlessly into contemporary bathrooms or en-suites.

7. Envirovent Silent 100 SIL100: Ultra-Efficient

The SIL100 series excels as an ultra-efficient, ultra-quiet bathroom extractor fan, operating at just 26.5dB(A) while delivering a powerful 26l/s (93 m³/h) extraction rate powered by a low-energy 8W motor that complies with Building Regulations Part F and L for effective condensation control. IP45-rated for safe installation in Zone 1 areas (with RCD protection), it features a durable ABS plastic body and a built-in backdraught shutter to block unwanted drafts, all backed by an impressive 5-year warranty for long-term peace of mind.

Available in versatile models—including the standard SIL100S, timer-equipped SIL100T (adjustable 2–30 minute overrun), humidistat+timer SIL100HT (auto-boost at 60–90% RH), PIR motion-sensor SIL100PIR for hands-free activation in small spaces, and pullcord SIL100PC for manual control—the range offers something for every bathroom setup, from en-suites to family rooms, with easy-clean detachable grilles and a 40,000-hour motor life ensuring minimal maintenance and reliable, silent performance year after year.

8. Manrose Quiet Fan QF100: Affordable Entry-Level

The Manrose QF100 remains one of the best-value quiet extractor fans, delivering a solid 21l/s (75 m³/h) extraction rate at a barely audible 27dB(A) thanks to its cleverly designed turning vanes that smooth airflow and reduce turbulence, all while using just 5W of power and fully meeting Building Regulations Part F for domestic bathrooms.

IPX4-rated, it’s incredibly easy to install with a simple two-screw fixing system, a built-in spirit level and a generous wiring terminal block. Available in multiple versions—including basic, timer (adjustable 1–20 min overrun), humidistat+timer, and pullcord models—plus a 3-year warranty as standard, the QF100 is the perfect no-nonsense choice for landlords, renters, or anyone wanting reliable, near-silent ventilation on a budget without sacrificing performance or longevity.

Which Quiet Extractor Fan Is Best for My Bathroom?

Small Rooms (<5m²): Go for CV2.1HT or VASF100 for ultra-quiet operation.
Large Rooms (>10m²): MF100T or MONS100T for power without roar.
Ultra-Quiet Pick: Vent Axia NBR or Greenwood CV2.1HT for near-silent continuous running.

You may have noticed that the silent fans such as the Greenwood Airvac CV2GIP and the Vent Axia Silent Fans have a lower extraction rate. Because of this these fans are better suited to smaller bathrooms, toilet or cloakroom areas. For larger bathrooms, the National Ventilation Monsoon is the best quiet extractor fan - operating at a decibel reading only slightly louder than rustling leaves.

Other options for silent condensation solutions include anti-fog bathroom mirrors which are ideal if condensation interrupts your morning routine, and inline fans which provide a discreet yet powerful way to control moisture levels.
