The best FFP3 masks, compared.
Top pick: Spanner In The Works FFP3 moulded 20-pack Best value: Spanner In The Works FFP3 10-pack – Lowest price per mask among the other EN149 packs with one count and at least 10 United Kingdom reviews, at about £11.95. Updated 21 October 2026.
An FFP3 mask is a disposable particle-filtering half mask to EN 149, not a surgical mask and not a reusable half facepiece with separate filters. You are usually buying it on amazon.co.uk for fine dust from sanding, cutting or insulation. A workplace uses the same class when a assessment needs assigned protection factor 20. That factor holds only when the model seals on your face. A beard, a gap at the nose, or an ear-loop strap removes the assumption. A title that only says FFP3 is not treated as EN 149 unless that standard is printed. What to check before you pay is set out in the [FFP3 mask buying guide](/hub/medical-protection/ffp3-mask/sub/ffp3-mask-buying-guide).

Personal buying guide
Question 1 of 2
Where will you wear it?
The Spanner moulded box of 20 at about £26.95 is titled for sanding, construction and DIY, at about £1.35 a mask. The amazon.co.uk line is 5.0 from 9 reviews, and the two captured UK texts say only that it is good as advertised and very good for the purpose. Those lines do not name a job, a seal or a strap. EN 149, a valve, a layer count and a harness are absent from the listing. The title does say disposable and moulded, and the box weight is listed as 420 g. A five-star average from nine ratings, with no fault written down, is a thin record beside the packs that have over a hundred reviews. Buy it when the moulded shape is what you want and you accept that the notes do not show how it fitted a face.
Pros
Cons
Best for: You want a moulded 20-count and you will judge the fit when it arrives.
Less suitable: You are choosing from the star line alone, or you need a standard and a harness printed first.
Specifications
Common questions
How many masks are in the box?
The title says a box of 20 moulded disposable FFP3 masks.
Does the listing state a valve or an EN number?
No. A valve, a layer count and an EN number are not stated on the listing.
How many review texts are saved?
The rating line says 5.0 from 9 ratings. Two short positive reviews are saved, and they name no job and no fault.
The Apex JADA ten-pack at about £17.99 prints EN149 in the title, and the detailed UK review describes a seal that filtered dust in a recycling-centre hall. The amazon.co.uk line is 4.8 from 11 reviews, and the page was first listed on 6 November 2025, so the star line is a small sample. That reviewer also says a lighter flame did not go out while the mask was worn, which is one anecdote rather than a fit test, and they call the mask a little tight and warm. The title lists construction, sanding, spray painting, cleaning, mould, fine dusts, and asbestos particles, and those words are title uses rather than a hazard rating. A valve, a harness and a layer count are not stated. At about £1.80 a mask it sits above the Spanner EN149 packs that have far more reviews. The asbestos wording is a use line, not evidence this mask is rated for asbestos work.
Pros
Cons
Best for: You want EN149 printed on a ten-pack and you will judge the fit on your own face.
Less suitable: Asbestos, spray, or any job that needs a stated harness and a larger review sample.
Specifications
Common questions
What standard does the title cite?
EN149, pack of 10, FFP3 dust mask. A valve is not stated.
Does the title mention asbestos?
Yes. The title lists asbestos particles among uses. That is title wording only. The listing has no HSE task assessment, and it is not evidence the mask is rated for asbestos work.
Does the listing state a valve?
No. A valve is not stated, and neither is a harness or a layer count.
The Spanner moulded box of 10 at about £16.95 is titled for sanding, construction and DIY, and the UK notes describe a dust seal while sanding paint off a door. The amazon.co.uk line is 4.6 from only 7 reviews, and the listing first appeared on 24 April 2026. One reviewer says a valve cuts condensation and another describes heavy-duty four-point straps, but neither the valve nor the harness is in the title, and EN 149 is not printed. One buyer found it a little uncomfortable and still reported a good seal. Seven reviews are not a basis for ranking the seal above the 1,975 notes on the Aura ten-pack. At about £1.70 a mask you are paying for a moulded cup the title names, and you would confirm any valve on the mask in your hand.
Pros
Cons
Best for: You want a moulded cup under £17 for ten and you will confirm any valve on the mask you receive.
Less suitable: You need the valve and EN 149 printed before you pay.
Specifications
Common questions
What shape is the mask?
The title says moulded disposable face masks, box of 10.
Does the title state a valve?
No. One UK review says a valve reduces condensation. Treat that as a review, not as a printed specification.
Which standard is in the product details?
None. The title says FFP3, and the product details do not cite EN 149.
The Spanner In The Works 20-pack at about £21.95 is the box United Kingdom reviewers use for fine dust, including bagging hay, where one buyer says particles collect in the mask rather than reaching them. Across 4.5 from 135 amazon.co.uk reviews, more than one person says the nose mould stops glasses steaming, and several mention handing out the individually wrapped masks. The title prints UK certified EN149, seven layers, and disposable, and it does not state a valve. One reviewer could not get a secure seal, so air bypassed the material, and another notes condensation inside during use. One comment praises heat-welded ear loops, which the title itself does not name as the harness. At about £1.10 a mask it is the top pick in this set when you check the seal on your own face before the dust starts.
Pros
Cons
Best for: You want a wrapped 20-pack with EN149 on the title for dusty jobs, and you will check the seal on your face.
Less suitable: You need a valve printed on the listing, or a head harness stated before you order.
Specifications
Common questions
How many masks are in the pack?
The title says a pack of 20, individually wrapped, seven-layer FFP3 masks.
Does the listing state a valve?
No. A valve is not stated in the title or the product details.
What standard does the title cite?
The title says UK certified EN149. It also says the masks are disposable.
This seven-layer listing at about £19.99 prints EN 149:2001+A1:2009 and a claim of more than 99% filtration, and UK reviewers describe wearing a fresh mask through a day of urban pollution until it looked soiled. The star line is 4.5 from 112 reviews. Comfort and an easy breath are repeated, and one review says the seal worked for a husband with a larger face. Pack size is not stated, so about £19.99 does not become a price per mask. The product-information ASIN is B0G2HHLSJ6 while the page URL is B0FFF9WSWN. Those two codes are not treated as one variant. A valve is not stated, and reviewers describe ear loops, including twisting them for a closer fit. One review calls the mask poorly made and suffocating, and a smaller face is described as slightly loose at the sides.
Pros
Cons
Best for: You can confirm the pack count on the live page and you want the full EN 149 string in the title.
Less suitable: You need a stated pack size, a valve, or a head harness before you order.
Specifications
Common questions
Which ASIN is on the product page URL?
The product-information ASIN is B0G2HHLSJ6. The page URL is amazon.co.uk/dp/B0FFF9WSWN. They are not merged into one variant here.
What filtration figure does the title claim?
The title claims more than 99% filtration efficiency, 7 layers, and EN 149:2001+A1:2009. Pack size is not stated.
Does the title state a valve?
No. A valve is not stated. Reviews mention ear loops, which the title does not specify.
The Spanner valved ten-pack at about £12.95 is the box UK reviewers use when an electric saw throws sawdust and they want a valve named on the title. Across 4.3 from 143 reviews, people mention a mask that stays put for some faces and is easy to breathe through, and several short reviews call the price fair. The title also says six layers, disposable, and individually wrapped. The product details never print EN 149. Ear-loop elastic is the repeated complaint: one review title says the straps break as soon as the mask goes on, and others call the fit too big so the filter rests on the face. The package weight prints as 11 g, which is not a usable mass for ten masks. It suits occasional sawing if you check the seal yourself, and the missing standard is the reason it sits behind the EN149 packs.
Pros
Cons
Best for: You want a valve on the title at about £1.30 a mask and you will check the seal on your face.
Less suitable: You need EN 149 printed on the page, or headbands instead of ear loops.
Specifications
Common questions
Does this mask have a valve?
Yes. The title says ventilated and with valve, six layers, pack of 10, individually wrapped.
Which standard is printed in the product details?
None. The title says FFP3, and the product details do not cite EN 149.
What pack weight is printed?
The listing prints package dimensions 29.9 x 26.3 x 4.9 cm and 11 g. The 11 g figure is unusually low for ten masks and is not used as a weight.
The 3M Aura 9332+ ten-pack at about £58.03 is the listing that prints EN 149:2001+A1:2009 FFP3 NR D, a Cool Flow valve, and red headbands, with 4.2 from 1,975 amazon.co.uk reviews. Buyers describe easy breathing through the filter when the size suits the face, and some say the straps are long enough to hold the mask. The same UK notes call the elastic very tight and prone to breaking as the mask goes on, and many describe the fit as small or far too small so the seal fails. The bullets say NR while a later attribute says reusable, and the model field says 9332 while the title says 9332+. Several reviewers doubt the masks are genuine 3M, which these notes do not verify. At about £5.80 a mask it is the dear end of the set, and the NR mark still means a single shift if you follow the bullet rather than the reusable line.
Pros
Cons
Best for: You want the printed EN 149 line and a valve, and the three-panel size suits your face.
Less suitable: Larger faces, or a budget that stays under a couple of pounds a mask.
Specifications
Common questions
Is this the valved 3M Aura?
Yes. The title says 9332+, FFP3, valved, pack of 10, and the bullets name the Cool Flow valve.
What reuse mark is printed in the bullets?
The bullets say EN 149:2001+A1:2009 FFP3 NR D and CE 0086. A separate attribute says reusable. Both are on the listing. Follow the NR bullet for a single shift.
What harness does the listing describe?
Colour-coded headbands, red for FFP3, plus an adjustable nose clip and a sculpted nose panel.
The Apex JADA ten-pack at about £9.99 is the lowest shelf price in this set, with a title claim of more than 99% filtration and the words UK certified, and with no EN number on the listing. The line is 4.2 from 19 United Kingdom reviews. Short reviews call it comfortable, say it kept dust out, and one buyer recommends it for spray paint and says their glasses did not fog. A particle mask is not a rating for spray-paint vapour. A valve, a layer count and wrapping are not stated, and a listing question about adjustable ear loops is not a specification. The product-information ASIN is B0FV2WTRHQ while the page URL is B0FV2VYCQH, and the title says packaging may vary. One review title says they are not face masks as such, and another says good mask, poor order, without explaining the order fault. At about £1.00 a mask the price is low, and the missing EN number is why that price stays behind the EN149 packs.
Pros
Cons
Best for: You are comparing the lowest pack price and you will check what arrives against the title.
Less suitable: You need an EN 149 number on the page, or a stated harness.
Specifications
Common questions
Which ASIN is on the product page URL?
The product-information ASIN is B0FV2WTRHQ. The page URL is amazon.co.uk/dp/B0FV2VYCQH. They are not merged into one variant here.
What does the title claim on filtration?
More than 99% filtration efficiency, UK certified, pack of 10, disposable. An EN number is not in the product details.
Does the listing state a valve?
No. A valve is not stated, and a layer count is not stated either.
The Spanner ten-pack at about £11.95 is the lower shelf price among the listings here that print EN149 and a pack of 10, and UK reviewers say it stops them breathing in a lot of dust. The line is 4.1 from 13 reviews, and the page was first listed on 24 April 2026, so that average is a short sample. The title says seven layers and individually wrapped, and one reviewer says the nose clip holds a seal and the cup keeps its shape when damp. A valve is not stated. Straps are the recurring fault: one buyer calls them flimsy, and another had the strap come off two masks while pulling them over the face. Reviewers also call the mask large and more suitable for a larger face. It is the best value here when you try the elastic before a dusty job and you treat 13 reviews as a thinner record than the 135 on the 20-pack.
Pros
Cons
Best for: You want the lower EN149 ten-pack price in this comparison and you will test the straps before a dusty job.
Less suitable: A smaller face, or a decision you want backed by more than 13 reviews.
Specifications
Common questions
Are these masks individually wrapped?
Yes. The listing title says the pack of 10 is individually wrapped.
Does the listing state a valve?
No. The listing does not state whether a valve is fitted.
What standard does the title cite?
The title says UK certified EN149 and FFP3, in a pack of 10 with 7 layers.
The 3M Aura 9332+ five-pack at about £50.79 is titled as valved FFP3, which is about £10.16 a mask and the highest price per mask in this set. The star line is 3.9 from 32 reviews, and the captured texts are from France, Italy, Germany and Spain, not the United Kingdom. This listing does not print an EN 149 sentence, so the ten-pack’s FFP3 NR D line stays on that other ASIN. An Italian review says one mask arrived when five were expected. A German review praises fit and breathing, and a French review mentions comfort, including a claim about chemical smells that this listing does not rate as vapour protection. Harness, layers and a reuse mark are not stated. Count the masks in the parcel, and compare this about £50.79 line with the about £58.03 ten-pack that does print the standard, before you treat the names as the same offer.
Pros
Cons
Best for: You specifically want a five-pack of the named Aura model and you will count what arrives.
Less suitable: You need United Kingdom review text, the EN 149 line on this ASIN, or a lower price per mask.
Specifications
Common questions
How many masks are in this pack?
The title says 9332+, FFP3, valved, 5 per pack. The item model number is 9332PRO5.
Are the saved reviews from the United Kingdom?
No. The captured reviews are from France, Italy, Germany and Spain. The rating line is 3.9 from 32. They are not used as British shopper opinion.
Does this listing repeat the ten-pack EN 149 string?
No. Standard, NR and D are not printed on this ASIN. Do not copy the ten-pack line onto this five-pack.
Scores use the ten amazon.co.uk listings kept in this comparison, the prices and star lines on those pages, and the review notes for the same ASINs. Shelf date 20 October 2026. This is not a laboratory test or a face-fit test. A title that says FFP3 is not scored as EN 149 unless EN149 or EN 149 is printed on that listing. Weights sum to 100. The highest score is the top pick. Best value is the lowest price per mask among the other EN149 packs with one count and at least 10 United Kingdom reviews.
Amazon evidence
30%Stars are the amazon.co.uk rating divided by 5, then multiplied by 20. A review-count band is added on top, and the block is capped at 30. If the saved review texts are not from the United Kingdom, the count bonus is 0. The 3M five-pack is in that position: 3.9 from 32, with the saved texts from outside the UK.
Listing fit
35%EN 149 printed on the listing, one pack count, FFP3 in the title, a valve or a harness stated on the listing, individual wrapping, and a layer count or a filtration percentage. UK certified with no EN number scores as a phrase. A product-information ASIN that differs from the page URL costs points. NR and reusable in the same listing also cost points.
Review outcome
20%United Kingdom notes that name a dust job and a seal score higher when the sample is large and a recurring fault stays visible. Under 10 reviews, or texts that name no job, stay low. Seven reviews cannot outrank a sample of hundreds. No United Kingdom review text scores at the bottom of this block.
Value
15%Price per mask is used only when the pack count is one number. Under about £1.25 with EN 149 on the listing scores at the top of this block. The lowest shelf price does not win when the EN number is missing. An unknown pack count cannot be turned into a per-mask price. Above £5 with the standard printed scores low.
Read the printed class and the standard before the layer count. A valve, a head harness and the letters NR change the job the mask can do. A title that says FFP3 is not EN 149 unless that standard is on the same listing.
An FFP3 mask is a disposable particle-filtering half mask to EN 149. It is not a surgical mask, and it is not a reusable half facepiece that takes separate filters. On amazon.co.uk the usual reason to buy one is fine dust from sanding, cutting, insulation and similar DIY. A workplace uses the same class when a COSHH assessment needs assigned protection factor 20. HSE assigns FFP1, FFP2 and FFP3 the factors 4, 10 and 20, and that 20 only holds when the model seals on your face.
Seven layers, or a claim of more than 99%, does not replace FFP3 to EN 149. Inward leakage is a separate test from filter efficiency. UK certified with no EN number is a phrase.
HSE says ear-loop respirators, even with clips, are not recommended as tight-fitting RPE for most people. Prefer a head harness you can fit-test. A daily seal check is not that fit test, and facial hair on the seal rules the mask out.
If the bullets say NR, an Amazon line that says reusable is not the EN mark. A particle mask does not filter gases or vapours. A title that lists asbestos is not an assessment. em6 covers only some short non-licensed tasks.
The listing has to show the class and the standard, not a layer slogan. An FFP3 mask should be marked FFP3 to EN 149. BSI’s public summary puts FFP3 filter efficiency at 99%, and inward leakage is a separate test, so a claim of more than 99% is not that standard. The words UK certified, with no EN number, score as a phrase. In this set the Spanner 20-pack at about £21.95 and the Spanner 10-pack at about £11.95 both print EN149. The Apex ten-pack at about £17.99 also prints EN149.
HSE does not recommend ear-loop respirators, even with a clip, as tight-fitting respiratory protective equipment. Prefer headbands when the mask is a workplace control you can fit-test. Only the 3M Aura ten-pack states colour-coded headbands, red for FFP3, and reviewers still call that mask small, with elastic that can break as it goes on. Several Spanner notes describe ear loops or straps that come off, and the title often does not name the harness at all.
Three typical situations, each with a recommendation from this comparison.
You want a wrapped pack for sanding, cutting or hay dust, and you will check the seal on your own face. The Spanner In The Works 20-pack is the top pick: EN149 is on the title, the price is about £21.95, and the line is 4.5 from 135 reviews. A valve is not stated, and at least one reviewer could not get a seal.
You want EN149 printed and a lower pack price than the 20-count. The Spanner 10-pack is the best value here, at about £11.95, about £1.20 a mask. The line is 4.1 from 13 reviews, first listed on 24 April 2026, and reviewers say the straps can come off. Try the elastic before a dusty job.
You want EN 149, a valve and headbands named on the listing, and the three-panel size has to suit your face. The 3M Aura 9332+ ten-pack prints FFP3 NR D and a Cool Flow valve, at about £58.03, with 4.2 from 1,975 reviews. The bullets say NR while another line says reusable. Many reviewers call the fit small.
The top pick is the Spanner In The Works 20-pack at about £21.95. It scores 81, the highest here, with EN149 on the title, a pack of 20 at about £1.10 a mask, and 4.5 from 135 United Kingdom reviews. Reviewers cite hay dust and glasses that stayed clear. At least one person could not get a seal. Best value is the Spanner 10-pack at about £11.95, a different ASIN, the next EN149 pack with one count and at least 10 UK reviews. Skip the 20-pack if you need a valve or a head harness printed before you order. Skip the 10-pack if you want a larger review sample than 13.
Spanner In The Works FFP3 10-pack
Lowest price per mask among the other EN149 packs with one count and at least 10 United Kingdom reviews, at about £11.95.
