BMC Super Quad Air Filter - FM321/21 Polaris Trail Boss

Established through their success in the world’s most prestigious competitions, BMC air filters are today renowned for setting a benchmark in terms of performance, reliability and manufacturing quality.

The characteristics of a cotton filter can be summarised simply: permeability, filtration, retention, re-use

• Permeability: presents minimal obstacles for maximum air flow
• Filtration: prevents foreign bodies from penetrating
• Retention: retains solid particles
• Reuse: cotton filters can be reused thanks to BMC-specific cleaning products

BMC’s air filters are designed specifically for Super quads and should be used with their prefilters.
