The best protection: Pfannenberg filter mats.

Sensitive electronics deserve the best protection against harmful particulate. The quality of a filter is defined by how many particles of a certain size can pass through the filter medium. This is known as filter class. The highest achievable filter class by coarse dust filters is G4.
G4 means that a filter prevents more than 90 % of all particles smaller than 10 μm from passing through. At Pfannenberg, G4 is standard for all our filter mats, fleece and fluted versions.
