FFP2 masks and KN95 masks are both respiratory protective devices designed to filter out particles from the air, including airborne contaminants such as viruses, dust, and pollutants. While they serve a similar purpose, there are differences in their standards, certification, and manufacturing regions:


1. Certification Standards:

  • FFP2 Mask: FFP2 stands for "Filtering Face Piece 2." FFP2 masks are certified according to European standards, specifically EN149:2001+A1:2009. These standards are commonly used in Europe and some other regions. FFP2 masks are designed to filter out at least 94% of airborne particles, including aerosols.


  • KN95 Mask: KN95 stands for "Chinese Standard for Respiratory Protective Devices." KN95 masks are certified according to Chinese standards GB2626-2006 or GB2626-2019. These standards are used in China and have also been adopted in other countries. KN95 masks are designed to filter out at least 95% of airborne particles, including aerosols.

2. Manufacturing Regions:

  • FFP2 Mask: FFP2 masks are typically manufactured in Europe and must comply with European Union standards. They are prevalent in European countries.


  • KN95 Mask: KN95 masks are primarily manufactured in China and must meet Chinese standards. However, they have gained global popularity due to their filtration efficiency.


3. Certification Bodies:

  • FFP2 Mask: The certification for FFP2 masks is usually issued by European Conformity (CE) bodies, which assess and confirm that the masks meet the EN149 standards.


  • KN95 Mask: KN95 masks are certified by Chinese authorities, and manufacturers must obtain certification from accredited Chinese testing laboratories.

4. Testing and Performance:

Both FFP2 and KN95 masks undergo similar testing for filtration efficiency, airflow resistance, and leakage. They are designed to provide a high level of respiratory protection against particulate matter. Both types of masks can filter out particles as small as 0.3 microns, including fine aerosol particles.


5. Design and Shape:

In terms of design and shape, FFP2 and KN95 masks may have slight variations, but they generally cover the nose and mouth, forming a seal to prevent the entry of contaminants.


6. Usage Recommendations:

It's important to note that both FFP2 and KN95 masks are intended for single-use or limited use, depending on the manufacturer's instructions. They are not typically designed for long-term use or reuse without proper disinfection.


In summary, the primary difference between FFP2 and KN95 masks lies in their certification standards and manufacturing regions. Both offer a similar level of particle filtration efficiency, with KN95 masks requiring a slightly higher minimum filtration efficiency according to Chinese standards. When choosing between them, it's essential to ensure that the mask is certified by a reputable organization and that it meets the standards and requirements of your specific region or country.
