Why Use the Official BMC Kit?

Use only original BMC regeneration products. Other cleaners or oils may be ineffective, may permanently damage the filter, and may invalidate its warranty. Apply oil evenly: too much may affect an airflow sensor, while too little may reduce filtration protection.

Follow the complete step-by-step guide for washing, drying, and evenly re-oiling a washable BMC cotton-gauze air filter with the WA250-500 kit.

How to Clean and Recharge a BMC Air Filter

How to Clean and Re-Oil a BMC Air Filter

  1. Remove the filter and clear loose debris
  2. Apply WADET500 detergent for 20–30 minutes
  3. Rinse gently with low-pressure water
  4. Air-dry completely away from direct sunlight
  5. Apply WAFLU250 evenly
  6. Blot excess oil before reinstalling
Oiling matters: Yes. Let the washed filter air-dry completely away from direct sunlight before applying WAFLU250. Oiling a damp filter can prevent even absorption. Apply oil evenly: too much may affect an airflow sensor, while too little may reduce filtration protection.

Recommended Service Interval

BMC recommends regeneration approximately every 20,000–25,000 km (12,400–15,500 miles). Inspect and service sooner in dusty, sandy, off-road, track, or other harsh conditions.
