BMC Air Filter Filtration Process & Technology

Multi-Layer Cotton Gauze

Multiple layers of oiled cotton gauze trap impurities while maintaining high airflow. This washable design is engineered for long service life.

Electrostatic Filtration

The oil coating creates a positive charge that attracts and captures negatively charged particles, ensuring cleaner intake air for your engine.

Epoxy-Coated Mesh

A durable alloy mesh with epoxy coating shields the filter media from petrol fumes, moisture, and oxidation—extending performance and lifespan.

Full Moulding Technique

Each filter frame is created from a single mold with no welded joints, giving the filter superior rigidity and a precise seal inside OEM airboxes.

Proven Performance & Durability

Together, these techniques make BMC Air Filters one of the most trusted options for both car and motorcycle applications. They combine efficient filtration, reusability, and long-term durability—making them a top choice among enthusiasts worldwide.
