6. 99.8% dust containment methodology
- Equipment: Bona Atomic DCS and commercial two-stage cyclonic extraction units connected directly to belt sanders, edgers, and buffer machines.

- Limitation notice: Dust containment captures airborne sanding discharge at the source; it is not a representation of a completely sterile or dustless home. Minor incidental surface wiping is standard practice. Read our detailed dustless sanding process.
