Special cotton filtering material soaked in low-viscosity oil
High-strength epoxy mesh resistant to gasoline vapors and oxidation
Washable cotton, therefore reusable
Optimal airflow ensuring minimal power loss compared to traditional paper filters
The characteristics of a cotton filter are summarized as permeability, filtration, retention, and reuse.

Permeability: offering minimal resistance for maximum airflow
Filtration: preventing foreign particles from entering
Retention: holding solid particles
Reuse: cotton filters can be reused thanks to BMC’s specific maintenance products
