The MARCHALD air filter protection must be applied over the motorcycle filter as if it were a sock.

Anti-water version of MARCHALD FILTERS, made of polyethylene with water-repellent surface treatment; it is used to prevent the filter sponge from coming into contact with water. To be applied in case of use in rain, puddles or fords. N.B. the duration of the water-repellent treatment can only be calculated if the surface is in constant contact with water, it is therefore practically impossible to calculate its duration if used on the motorbike. It is therefore advisable to check its efficiency after each use.
