Since Coronavirus outbreaks in Europe.  FFP2 have been highly demanded from China.  Many people don’t know what FFP2 is, FFP2=KN95=N95? Is CE certificate you received valid? How to protect yourself?

What is FFP2?

An FFP mask (Filtering Facepiece Particles, also called respiratory protection mask) is a type of protective mask certified by the European Union that serves to protect against particulates such as dust particles and various viruses in the air.

European Standard EN149 defines the following classes of “filtering half masks”, they are entirely or substantially constructed of filtering material:

Class Filter penetration limit(at 95 L/min air flow)Inward leakage
FFP1 Filters at 80% of airborne particles <22%
FFP2 Filters at 94% of airborne particles <8%
FFP3 Filters at 99% of airborne particles <2%

FFP2 is considered Personal Protective Equipment (PPE). CE number of the certification body + EN 149: 2009 + FFP2 + acronym (NR or R) should be shown on product


Lately health authorities often reference these standards when making respirator recommendations, stating, for example, that certain populations should use an “N95, FFP2, or KN95” respirator. This document is only intended to help clarify some key similarities between such references, specifically to the following FFR performance standards:

 • N95 (United States NIOSH-42CFR84)

 • FFP2 (Europe EN 149-2001)

 • KN95 (China GB2626-2006)

Is CE certificate you received valid?

In the past two weeks, I have received 60-80 CE certificates, among of them only 5 are valid. Even some factories and agents don’t realize that their certificates are not valid.

Since February, many newcomers start producing masks. In order to export to EU, some factories applied for “CE certificate” from notified body who are not acknowledged by EU.

Here is the link for “suspicious certificate “updated by European Safety Federation on Apr. 7th.for your information.

How to protect yourself?

  1. Verify all certificates and documents including inspection report
  2. Company background check
  3. Oversee and inspect the production. As qualified factories are over demanding. It happens that some factories just take products from around unqualified factories (like newcomers) as their own to sell
  4. Sign a contract with clear responsibilities and obligations. Make sure once you have dispute that you could have the legal support.
