The best MVHR units, compared.
Top pick: Envirovoid single-room MVHR Best value: EUROPLAST EER100 – About £189.90, with 29 m³/h stated and a wall switch in the box, at 3.9 from 70 reviews. Updated October 2026.
MVHR means mechanical ventilation with heat recovery sold on amazon.co.uk. You are either treating one damp room or comparing a loft box with a kit. A push-pull wall unit and a ducted unit are different objects, so a recovery percentage alone does not rank them. Then check airflow at the speed you will leave running, noise where a figure was measured, and whether the controller and ducts are in the box. Approved Document F, 1 (2021 edition, England) sets rates in litres per second. A product title is not a commissioned system. Read the [MVHR buying guide](/hub/heating/mvhr/sub/mvhr-buying-guide) for the checks, and [single-room and whole-house MVHR](/hub/heating/mvhr/sub/mvhr-single-room-vs-whole-house) for sleeve versus loft box. Mechanical ventilation with heat recovery, MVHR, is a fan that takes stale indoor air out and brings outdoor air in while a heat exchanger keeps some of the warmth. Tell them apart by system type, by whether airflow and noise still agree when you read the same page twice, and by whether the controller and ducts are in the box. Alternate-flow single-room units use one fan that reverses through a ceramic core. A five-star line on three reviews is a thin sample.

Personal buying guide
Question 1 of 2
What are you ventilating?
Envirovoid’s single-room unit at £360.00 shows 5.0 stars from only three amazon.co.uk reviews—enough for enthusiasm, not for a stable quality picture. Buyers describe a smart-looking wall fan that reduced window fogging after about a week and smelled fresher, with quiet running on the 20 dB low claim. The listing advertises up to 90% recovery and a HEPA filter with 99.7% of pollen and PM2.5, but no filter standard number is printed, and airflow is not credibly stated—a capacity field even shows cubic centimetres. Core hole range is 100–160 mm with remote in the box. It may suit a dry bedroom with mild condensation if install goes well, but do not read three perfect scores as beating the 182-review LIRAST on reliability.
Pros
Cons
Best for: A single dry room where aesthetics and early positive reviews outweigh sparse data and unverified HEPA wording
Less suitable: Whole-bathroom boost duty, buyers who need stated m³/h or l/s figures, or risk-averse shoppers who rely on review count
Specifications
Common questions
What filter does the listing claim?
HEPA, with 99.7% of pollen, dust mites and PM2.5. No standard number is printed.
What airflow is stated?
Airflow is not stated. A capacity field prints 30 cubic centimetres, which is not a credible airflow.
How many reviews are on the listing?
5.0 from 3 reviews.
Across 182 amazon.co.uk reviews at 3.9 stars, the white LIRAST EER100 behaves like a budget through-wall alternate-flow fan for one small room, not a whole-house system. Buyers who measured the wall first report a straightforward fit with the 300–555 mm telescopic duct and notice fresher air in a living room without opening a window. The listing claims up to 85% heat recovery, but several UK reviewers say incoming air still feels cool, so treat the percentage as marketing until you judge comfort in your room. Noise splits the sample: bedrooms are often fine, yet a large kitchen-diner can feel too loud for conversation. Instructions come up weak, and the sleeve assumes roughly 300 mm minimum wall thickness—easy to miss on a cavity wall. At £123.12 it is the cheapest heat-recovery row in our set and carries the top score badge in this comparison, mainly on review volume rather than a lab test.
Pros
Cons
Best for: One small bedroom or living room with an external wall around 300–555 mm thick and tolerance for fan noise
Less suitable: Large open-plan kitchens, whole-flat ventilation, or walls thinner than the telescopic range
Specifications
Common questions
Is this a through-wall unit?
Yes. The listing gives a telescopic duct of 300–555 mm.
What heat recovery and airflow are stated?
Heat recovery is up to 85%. Airflow is not stated.
What is included?
The included line says recuperator. Two filters are described. The grade is not stated.
The anthracite LIRAST EER100 is the same hardware story as the white listing: decentralised single-room, 300–555 mm sleeve, up to 85% recovery on the page, and the same 3.9 average from 182 reviews—do not treat anthracite as a separate review sample. You pay about £16 more at £139.15 for colour that matches darker render or window frames. Review themes match the white row: easy install when wall depth fits, better air in a living room, bathroom warmth when left running, but cool-feeling supply air and loud operation in bigger spaces. Model text on the listing prints EER 100 125 150, which confuses size choice until you confirm the 100 mm path you are drilling. Pick anthracite for aesthetics; pick white if you want the lowest shelf price in the pair.
Pros
Cons
Best for: Same jobs as the white LIRAST where anthracite finish matters on the external elevation
Less suitable: Buyers expecting a quieter or more reviewed variant—review text is shared with the white ASIN
Specifications
Common questions
How does this differ from the white LIRAST listing?
The variant is anthracite and the model number prints EER 100 125 150. The review text matches the white listing, so the 182 reviews are not a second sample.
Which rooms does the listing name?
A bullet calls it a bathroom MVHR. The room-type field lists bedroom, home office and living room. No IP rating is stated.
What wall depth is listed?
The telescopic duct is 300–555 mm.
EUROPLAST’s EER100 at £189.90 is one of the few rows here that states a hard airflow number—29 m³/h—plus a wall switch in the box, which matters when Brookvent lists “unit only”. Seventy reviews sit at 3.9 stars: several UK buyers describe low bedroom noise and a few degrees of heat held compared with plain extract, though others find an office install louder than the 35 dB claim. A recurring complaint is the buttons wired back to front, so off and on feel reversed until you relabel or rewire. The listing prints both Type G and Schuko plug fields, so check the plug on delivery before you assume a UK fused spur layout. Heat recovery percentage is not stated; treat it as a moving-air wall fan with recovery hardware rather than a datasheet-perfect MVHR unit. It earns the best-value badge in this folder on price against stated airflow and included switch.
Pros
Cons
Best for: A bathroom or bedroom where you want a stated 29 m³/h figure and a wall switch supplied without hunting a separate controller
Less suitable: Noise-sensitive home offices, buyers who need a printed heat-recovery percentage, or installs that cannot tolerate reversed switch logic
Specifications
Common questions
What airflow is stated?
29 cubic metres per hour. The heat-recovery percentage is not stated.
Which plug does the listing show?
One field says Type G and another says a Schuko plug.
Is a wall switch included?
Yes. The included line says wall switch. The room type is bathroom. No IP rating is stated.
Swiftair’s HRU100 at £400.00 is priced as a ducted kit with 100 m³/h in the title and “four rooms” in the name, yet UK review text describes a loft-mounted unit and at least one buyer received a two-room box and bought extra vents and pipes. Ten reviews at 3.9 stars still tell a useful mould-and-condensation story in a 1980s flat where moving air around the dwelling cut moisture and black mould, with one install still quiet after a year. Physics constraints remain: the fan must sit lower than ceiling terminals, moisture stayed above 60% for nearly two months in one case, and noise exceeded expectations for another buyer. Heat recovery is not stated on the listing. Budget for ducts beyond the cord listed in the box before you treat this as a complete multi-room MVHR package from one click.
Pros
Cons
Best for: Retrofit flats with loft space and willingness to verify kit contents and ceiling routing before cutting holes
Less suitable: Buyers who need the four-room title to match the delivered parts, or single external-wall flats with no duct path
Specifications
Common questions
Is this a single-room fan?
No. The title says a complete 4-room kit at 100 m³/h. Reviews describe a loft unit.
Does the box match the 4-room title?
A UK review says the box was a 2-room kit and extra vents and pipes had to be bought. Ducts and terminals are not itemised.
What electrical connection is listed?
Type G, corded electric, one speed. The noise field says 30 decibels.
Vent-Axia’s HR100R at £319.00 is a different object from the ceramic wall fans: a small ducted heat-recovery unit with 18 l/s FID on the listing, two speeds, and top access aimed at loft mounting—not a 100 mm through-wall sleeve. Six reviews at 3.8 stars include a compact retrofit that kept a shower and small bathroom clear of humidity, which aligns with ducted distribution rather than one-hole push-pull. Packaging drew criticism: cardboard-only transit and a bent condensate drain in one delivery, though the buyer still judged the unit sound. Instructions and port labelling confused an Irish install. Heat recovery percentage and filter grade are not stated on the listing. Step up here when you can run ducts and condensate to a loft box; do not compare the price directly with £123 wall fans without adding duct work.
Pros
Cons
Best for: Loft or ducted retrofits for a bathroom or bedroom zone where 18 l/s FID matches your installer’s layout
Less suitable: Flats with one external wall only, DIYers expecting a core drill and grille, or buyers who need rich amazon review depth
Specifications
Common questions
What type of unit is this?
A two-speed heat recovery unit with top access described as suited to a loft. It is not a push-pull sleeve.
What airflow is stated?
18 litres per second FID. The heat-recovery percentage is not stated.
What did reviews say about the drain?
A condensate drain is mentioned because one arrived bent. Included components are not stated.
Brookvent’s Aircycle ONE 100 at £204.99 sits in an awkward spot on the listing: only four amazon.co.uk reviews at 3.8 stars, conflicting airflow lines (3/4/7 l/s versus 17 l/s on the same page), and a noise field that prints 5 dB—clearly inconsistent with real fan physics. Quiet running and helpful seller support appear in the tiny sample, but a buyer also reports a wall switch not in the box and an extra controller cost that was not available on amazon.co.uk at the time of review. The alternate-flow cycle can produce an audible click about every 70 seconds when the fan reverses, which matters in a bedroom. Up to 82% recovery is claimed, yet you should verify controls and airflow on paper before paying Vent-Axia money for an unproven listing. Consider it only if you accept sourcing switches elsewhere and reading the manual against the printed conflicts.
Pros
Cons
Best for: A quiet bedroom trial where you will confirm controller parts and ignore inconsistent catalogue numbers before fixing the wall
Less suitable: Shower-room boost expectations, buyers who need everything in one amazon order, or anyone who wants a deep review pool
Specifications
Common questions
Is the controller in the box?
The included-components field says 1 unit. Reviews say the wall switch is not supplied.
Which airflow figure is on the listing?
The file prints ONE 100 at 3/4/7 l/s and also 17 litres per second. Those figures conflict.
What noise figure is printed?
The noise field says 5 decibels. Treat that figure as unsettled because the same listing conflicts on other numbers.
LINGGONGAIR’s VT125-WIFI at £216.54 targets buyers who want app, remote and button control on a 125 mm single-room unit with 60 m³/h stated and roughly 40 cm depth—plan the core drill accordingly. Twelve reviews at 3.7 stars praise straightforward install with a template, quiet running in several rooms, and a washable filter as a running-cost talking point. The Tuya app name appears in buyer text alongside the supplied remote. Limits show up in harder cases: one cottage install saw unchanged window condensation after three weeks of continuous use, and other comments say effectiveness drops in larger spaces. Heat recovery is not quantified on the listing. Power draw is higher than the 2 W LIRAST row at 12 W. Pay the premium for connectivity and airflow on paper, not for proof it will dry a cold single-glazed bedroom on its own.
Pros
Cons
Best for: Smaller rooms with external wall depth near 40 cm where app scheduling and 60 m³/h on the listing match your plan
Less suitable: Cold cottages with persistent condensation, large open rooms, or buyers who need a stated recovery percentage
Specifications
Common questions
How is it controlled?
The listing says app, remote and button. A review names the Tuya app. A remote is listed in the box.
What airflow and depth are stated?
60 cubic metres per hour. Depth is 39.9 cm. A review notes about 40 cm and the need for the right core drill.
Does the listing name a bathroom?
The room-type field includes bathroom, home office and kids' room. No IP rating is stated.
fans4less lists the CFLO250 at £340.23 as a whole-house ducted unit with 550 m³/h in the title, up to 75% efficiency and seven speeds, yet the listing shows no duct kit line and only five reviews at 3.7 stars. The sole substantive review body says it works better than expected—useful optimism, not a commissioning record. Treat the “whole house” wording as a capacity headline on the appliance, not proof that one amazon basket ventilates every wet room to Part F rates. Weight, dimensions and included parts are largely unstated compared with wall fans. This row suits someone already planning a duct network with a merchant, not a flat owner buying the only ventilation product of the year from a single ASIN.
Pros
Cons
Best for: A planned ducted install where an installer sizes a central unit and sources ducting outside this listing
Less suitable: One-room condensation fixes, buyers who expect ducts in the box, or evidence-hungry shoppers—review depth is minimal
Specifications
Common questions
What does the title claim?
A whole-house unit, 550 m³/h, up to 75% efficient, with 7 speeds.
Is a duct kit listed?
No. The rank sits under Ducting and a duct kit is not listed.
What do the reviews say?
The listing count is 5. The only review body says it works better than expected.
Nine amazon.co.uk listings are on this page. The score uses the star line and the review count for that ASIN. The white and anthracite LIRAST listings share one pool of 182 reviews, and those counts are not added. There is no lab test. A recovery percentage, an airflow line or a noise field is the seller’s text. Where one listing prints two airflow or noise figures, neither figure is treated as settled. The top pick is the white LIRAST EER100, the listing with the top score award. Best value is the EUROPLAST EER100, a different listing, because 29 m³/h is stated and a wall switch is in the box. Rows after those two awards follow the amazon score. The weights sum to 100.
Amazon evidence
40%Stars and the review count come from the amazon.co.uk listing for that ASIN. A 5.0 from 3 reviews is not the same evidence as 3.9 from 182. The two LIRAST counts are one shared pool and are not added.
System type and airflow
25%A push-pull wall unit and a ducted loft unit are different objects. Airflow is read at the speed you would leave running. Two airflow lines on one page, or a capacity in cubic centimetres, are not a settled rate.
Noise, wall or ducts, and the box
20%A noise figure counts when the listing does not print a second figure that disagrees. A 300 mm wall limit, a missing switch, or a four-room title that a review says arrived as two rooms, changes how far that listing can be trusted.
Shelf price
15%The price is the amazon.co.uk card in GBP, not an installed whole-house quote. The top pick is the white LIRAST on score and review volume. Best value is the EUROPLAST, where airflow and a wall switch are stated.
MVHR here is a fan that exchanges stale air and outdoor air and keeps some of the warmth. The decision is the system type, then whether airflow, noise and the box contents survive a second look at the same listing. A recovery percentage is not a bill saving, and a product title is not a commissioned system under Approved Document F. Shelf prices were read on 20 October 2026. There is no lab test.
Mechanical ventilation with heat recovery, MVHR, is a fan that takes stale indoor air out and brings outdoor air in while a heat exchanger keeps some of the warmth. The nine amazon.co.uk listings here are the units left once extractor fans and filter packs are set aside. You are either treating one damp room or comparing a loft box with a kit.
Up to 85%, up to 82% or up to 90% is a heat-exchanger line on the listing. LIRAST reviews still describe cool incoming air. The Centre for Sustainable Energy discusses savings for this system type in airtight homes. That is not a result for these shelf prices.
LIRAST’s sleeve is about 300–555 mm, and a thinner wall was easy to miss. Brookvent’s included line is one unit, and reviews say the switch is extra. Swiftair’s title says four rooms. A UK review says the box covered two.
The white and anthracite listings share one pool of 182 reviews at 3.9 stars. They are not 364 reviews. A 5.0 from 3 reviews on Envirovoid is a thin sample, not a larger one than the LIRAST pool.
System type comes before any recovery percentage. A push-pull wall unit serves one hole. The LIRAST pair, EUROPLAST, Brookvent, LINGGONGAIR and Envirovoid are that type. Vent-Axia HR100R is a small ducted loft unit. fans4less CFLO250 is titled as a whole-house unit. Swiftair HRU100 is a ducted kit. Do not line them up on an up to 85% claim alone. Airflow is the figure at the speed you will leave running, in l/s or m³/h, checked against the room. EUROPLAST states 29 m³/h.
Noise only counts where a figure was printed, and only when the page does not print a second figure that disagrees. The white LIRAST prints 27/32 dB(A) at 3 m and a field of 44 dB. Anthracite prints 45 dB in that field. Reviews mention a click when an alternate-flow fan reverses, about every 60 to 70 seconds. Brookvent’s noise field prints 5 dB. That figure is unsettled. EUROPLAST prints 35 dB. LINGGONGAIR prints 45 dB. Envirovoid prints 20 dB on low, from three reviews. Swiftair prints 30 dB.
Three typical situations, each with a recommendation from this comparison.
You have one external wall and you want a single hole rather than ducts. The white LIRAST EER100 is the top pick at about £123.12, with 3.9 from 182 reviews and a 300–555 mm sleeve. Measure the wall before you drill. Incoming air can still feel cool.
You are renovating a bathroom or utility room and you want a number on the page, not only a recovery percentage. The EUROPLAST EER100 is best value at about £189.90, with 29 m³/h stated and a wall switch in the box. That is not the Part F high rate for a shower by itself. The listing prints both Type G and Schuko.
You are comparing a ducted unit with a wall fan and you can run ducts. The Vent-Axia HR100R at about £319.00 states 18 l/s FID and top access for a loft. It is not a core-drill sleeve. Check the condensate drain on delivery. Six reviews is a small sample.
The top pick is the white LIRAST EER100 at about £123.12. It has the top score in this set, 3.9 from 182 reviews, on a through-wall unit with a 300–555 mm sleeve. That score is stars and review count, not a lab test, and the anthracite listing shares the same reviews. Best value is the EUROPLAST EER100 at about £189.90, because 29 m³/h is stated and a wall switch is in the box. Skip the LIRAST if the wall is thinner than about 300 mm or you need ducts. Skip the EUROPLAST if you need a printed recovery percentage or a plug that is only Type G.
EUROPLAST EER100
About £189.90, with 29 m³/h stated and a wall switch in the box, at 3.9 from 70 reviews.
