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.
- Capture Efficiency: Dual cyclonic separation with HEPA filtration captures up to 99.8% of airborne wood dust particulates down to 0.5 microns at the tool head before particles can enter ambient air, HVAC ductwork, or adjoining living quarters.
- 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.
