The sacrificial layer

Every filtration stack has one cheap part in front whose job is to be replaced. Neglecting it does not stop the system working immediately; it quietly shortens the life of the part behind it.

Check the fitment

Filters are specific to blower units. This set is named for STAHLWERK fresh-air helmets, and a filter that nearly fits leaves an unfiltered path — which defeats the entire arrangement.

Sources

Every figure above comes from the manufacturer’s published specification for this reference. Fields the listing does not publish are left out rather than estimated. Market availability was verified per market on the EAN.
