Buying respiratory protection online should not feel like a guessing game, but counterfeit and misleadingly labelled masks are still common. The good news is that most fakes can be spotted quickly if you know what real certification looks like and which documents to ask for.
📋 Key Takeaways
- For FFP2 and FFP3 respirators, look for EN 149:2001+A1:2009 plus a CE or UKCA mark and, for CE, a 4-digit notified body (NB) number.
- Certification is more than a logo, genuine products have a Declaration of Conformity and traceable manufacturer details.
- Many “CE” or “FFP2” claims are misleading, especially on generic masks with no model name, no standard, or no certificate.
- If you cannot verify the certificate, approved body, and model, treat the product as unverified and choose a trusted supplier.
What “Certified” Actually Means (UK and EU)
“Certified” is often used loosely. In PPE terms, it should mean the product has been assessed against a recognised standard and is legally placed on the market with the required conformity markings and documentation.
Respirators (FFP1, FFP2, FFP3): the key standard
For filtering facepiece respirators in the UK and Europe, the main standard is:
- EN 149:2001+A1:2009 (commonly shortened to “EN 149”)
FFP2 and FFP3 are PPE and classed as Category III (serious risk). That matters because it requires stricter conformity assessment than simple self-declarations.
Surgical masks (Type I, Type II, Type IIR): a different category
Medical or “surgical” masks are not the same as respirators. They are tested differently, usually to:
- EN 14683 (bacterial filtration and splash resistance for Type IIR)
A Type IIR mask is designed primarily to protect others from the wearer’s droplets and resist splashes, it does not provide the same inward leakage performance as an FFP respirator.
A genuine FFP2 or FFP3 respirator sold for the UK/EU market will normally show the standard (EN 149) and a clear manufacturer + model identification. If a listing only says “CE certified” without the standard and model, that is a red flag.
Quick refresher: FFP2 vs FFP3 (what the markings are trying to guarantee)
Mask Comparison
| Feature | FFP2 | FFP3 |
|---|---|---|
| Minimum filtration (EN 149) | 94% | 99% |
| Max total inward leakage (EN 149) | 8% | 2% |
| Typical use | Dusts, non-toxic aerosols, many workplace particulates | Higher-risk particulates, finer dust, more demanding tasks |
Note: performance depends heavily on fit. Even a genuine FFP3 can underperform if it does not seal to your face.
Step-by-step: How to verify a mask is genuinely certified
1) Check the mask itself for the required markings
For an EN 149 respirator (FFP2/FFP3), you should typically see markings printed on the mask such as:
- Manufacturer name or trademark
- Model number (not just “FFP2”)
- EN 149:2001+A1:2009
- FFP2 or FFP3
- NR or R (Non-Reusable or Reusable)
- D (optional, Dolomite clogging test)
- CE and often a 4-digit NB number for CE-marked PPE
If the mask is completely blank, or only says “FFP2” with no standard and no manufacturer, treat it with caution.
2) Check the packaging for traceability (lot numbers, addresses, instructions)
Genuine PPE packaging normally includes:
- Manufacturer or importer name and postal address
- Product name and model
- Batch or lot number
- User instructions (or an IFU leaflet)
- Storage conditions and sometimes an expiry date
A plain unbranded box, vague branding, or missing manufacturer address are common counterfeit signs.
3) Confirm the standard matches the type of mask being sold
Common examples of mismatches:
- A mask advertised as “FFP2” but only references a non-EN standard, or no standard at all
- A “medical mask” advertised as “FFP2-level protection” without EN 149 certification
- A product described as “N95/FFP2” without clarity on which standard it is certified to
N95 (NIOSH, US) is not the same certification scheme as FFP2 (EN 149), even if performance can be similar in some cases.
4) Ask for the Declaration of Conformity (DoC)
A serious seller should be able to provide a Declaration of Conformity for the exact model. The DoC should clearly state:
- Manufacturer details
- Product model identification
- The standard(s) used, for respirators: EN 149:2001+A1:2009
- The conformity route and the assessment body (where applicable)
If you receive a generic PDF that does not match the model name on the listing or box, be cautious.
5) Validate the notified body or approved body (do not just trust the number)
If the mask shows a CE mark with a 4-digit number, you can look up that notified body on the EU database (often called NANDO). What you are checking:
- The body is real
- It is authorised for PPE and relevant standards like EN 149
- The certificate references the correct manufacturer and model
Counterfeiters sometimes print a real NB number that belongs to a different company or is not authorised for that product type.
6) Watch for “test reports” that are not certification
A lab “test report” is not the same as certification. Red flags include:
- Reports with no lab accreditation details
- Reports that test only filtration material, not the whole mask performance (fit, leakage, breathing resistance)
- Documents that do not name the exact model and production site
The most common signs of fake or misleading masks
Benefits (of doing a proper authenticity check)
- You avoid masks with unknown filtration or high leakage
- You reduce risk in dusty or high-exposure environments
- You get consistent fit and performance, especially across repeat orders
- You keep compliance paperwork tidy for workplace use
Strong red flags to look for
- “CE approved” with no EN standard listed
- “FFP2” printed but the mask has no manufacturer name or model
- Poor printing quality, spelling errors, low-quality packaging
- A CE mark that looks wrong (odd spacing or proportions)
- A certificate that names a different company than the one on the box
- Prices that are dramatically below market norms for branded PPE
If you need respiratory protection for hazardous dusts or regulated work (for example, high-risk workplace exposure), do not rely on a mask with unclear certification. Use verified PPE from a reputable supplier and ensure you have the correct RPE selection, face fit testing where required, and training.
Buying online safely: a practical checklist
Before you place an order, you should be able to answer “yes” to most of these:
- Is the exact model stated (not just “FFP2 mask”)?
- Is EN 149:2001+A1:2009 shown for FFP respirators?
- Are there clear photos of the mask markings and packaging?
- Can the seller provide a Declaration of Conformity on request?
- Is the supply chain credible (UK-based business details, VAT info, returns policy)?
- Does the product arrive with lot/batch traceability?
Fit is the other half of protection. Even a genuine, certified FFP3 can leak if it does not seal to your face. In workplaces, face fit testing is often required to confirm the right model and size for each wearer.

If you are unsure, here is the safest approach
If anything about a mask’s certification feels unclear, do not try to “decode” it after the fact. Choose a product where the model, standard, markings, and documentation are straightforward from the start, and buy from a supplier that can support you with paperwork if needed.
