Read on as we explain these differences and help you select the right FFP mask for you.
What does it mean if a mask is an FFP1, FFP2 or FFP3?
The terms FFP1, FFP2 and FFP3 masks are seen more frequently recently due to coronavirus, however these types of masks have been used across multiple industries for years.
FFP stands for Filtering Face Piece, referring to a half face style mask. They are a form of disposable RPE (Respiratory Protective Equipment) and work by filtering out the smallest air particles to protect to wearer from respirable dust, smoke, and aerosols.
Unlike surgical masks, FFP masks protect the wearer against incoming and outgoing particles, e.g., an FFP2 mask will protect both the person wearing the mask and the people around them.
Each FFP mask conforms to the EU standards EN 149: 2001 the masks are then split into the 3 FFP categories determined by their protection level: FFP1, FFP2 and FFP3.
Before we jump into the different properties of the FFP1, FFP2 and FFP3 masks, there are some terms that are useful to understand.
IMPORTANT FFP MASK TERMS
Occupational Exposure Limit (OEL): OELs are standards that determine the amount or concentration, of a hazardous substance allowable in the workplace air.
Assigned Protection Factor (APF): Indicates the factor by which the wearer is protected from hazardous substances. For example, an FFP mask with an APF of 4 will reduce the hazard of the wearer breathing in toxic substances by 4 times
FFP1
FFP1 masks are the most basic FFP masks offering a limited amount of respiratory protection.
FILTER
These masks have the least number of filtering layers meaning that they are also the easiest to breathe in. An FFP1 mask should filter at least 75% of the substance it is protecting the wearer against. They are perfectly capable masks depending on the hazard.
These masks tend not to have a valve but may be purchased with one to aid in exhalation. Moldex 2365 Classic FFP1 NR D valved – Rapid Fire Supplies
SHOULD I WEAR AN FFP1 MASK?
Deciding which FFP mask is right for you does not need to be tricky! Do you work in the painter and decorator industry? Or dabble in DIY at home? Do you teach a woodwork class? Perhaps you are onsite smoothing cement or a gardener whose hay fever is playing up? The FFP1 mask is suitable for all the above and more!
Here are the types of industries that may benefit from wearing an FFP1 mask and the types of hazards the FFP1 mask would protect them from.
INDUSTRY/ROLE | PROBLEM/HAZARD | MASK TO PROTECT |
Painter and decorator | Sanding down an item | FFP1 |
Shopper | COVID-19 | FFP1 |
DIY Enthusiast | Non-toxic paint | FFP1 |
Woodwork | Small wood shavings | FFP1 |
Gardener | Pollen allergy | FFP1 |
Construction worker | Pouring cement | FFP1 |
Electrician | Working in a dusty loft | FFP1 |
Keep in mind that FFP1 masks can protect the wearer against irritating, non-toxic substances such as brick dust, cement, limestone and pollen, but these masks will not provide enough protection if the substance is toxic – a higher standard would be required.
STANDARDS
FFP1 masks generally have a 4X OEL and a 4X APL.

FFP2
An FFP2 mask is the equivalent of a US N95 standard mask. These masks were initially created to protect people against infectious diseases, as such FFP2 masks have been recommended by the WHO (World Health Organisation) as the best option to protect people from COVID-19.
At the time of writing, FFP2 masks are compulsory on public transport and in shops in Germany, this has been the case since January 2021 to protect people from COVID-19. This is also currently the law in Austria.
The FFP2 mask has currently not been made compulsory in the UK.
FILTER
FFP2 masks have more filter layers than an FFP1 meaning that it offers the wearer a higher level of protection.
It is more commonplace to see a valve in an FFP2 mask. This can help to reduce a build-up of heat in difficult working conditions increasing the comfort of the wearer.
An FFP2 mask offers 94% of Bacterial Filtration Efficiency.
USE
As before mentioned, FFP2 masks were initially created for infectious disease due to its superior protection against small particles in the air.
However, they have been used to protect people in a variety of industries for years.

INDUSTRY/ROLE | PROBLEM/HAZARD | MASK TO PROTECT |
Doctor/nurse | Infectious disease | FFP2 |
Miner | Large amount of dust | FFP2 |
Agriculture | Mouldy hay | FFP2 |
Metal workers | Foundry fume | FFP2 |

EXAMPLE
For a top quality FFP3 mask we recommend the Moldex 2535 Speciality FFP3 Mask. Not only does it offer unmatched protection to the user it also includes comfort features such as a foam nose bridge and fabric straps.
One of the straps has a ‘handy strap’ that can be easily unclipped to allow the mask to hang around the neck when not in use, this helps reduce waste and the number of disposable masks used.
