Reusable P3 Filter

Filters are split in different classes according to their capacity gas filters or their efficiency (particle filters).
The class of a particle filter indicates how efficient the filter is in filtering out particles:

  • class 1: 80%, 
  • class 2: 94%, 
  • class 3: 99.95%

Filter selection
Contaminants come in different forms – generally: aerosols (dusts, mists, fibres, fumes, microorganisms) or gases or vapours. You can choose between the filter types to protect against one of these forms or a combination of both of them. The following table shows you the colour coding of filters according to EN 14387 – which helps you to determine which filter type is needed for the contaminants you are dealing with.
