The dust problem with traditional sanding
Dust from sanding machines gets everywhere. It gets into clothes and wardrobes, into kitchen cabinets, into bedding, into curtains and drapes, and into your lungs. Traditional sanding processes remove as little as half the airborne dust or even less. Microscopic particles can remain in a room for days after the floor has been sanded.
Apart from the mess, dust particles cause irritation, allergic reactions and severe respiratory illness. Wood dust is proven by the World Health Organisation to be carcinogenic to humans. The health risk applies to everyone in the house, not just the person running the sander.
Bona DCS -- 99.99% dust containment
The Bona Dust Containment System (DCS) removes 99.99% of floor sanding dust. A timber floor can actually be sanded without the slightest trace of dust left in the home.
Nothing needs to be covered up, taken down or put away before sanding starts. On completion, there is no major clean-up needed -- in fact no clean-up at all. The air coming out of the Bona DCS is typically cleaner than the air already inside the house.
When a dust-free system exists, there is no good reason to sand without one. Placing anyone's health at risk is no longer acceptable for professional contractors.
How the system works
The purpose-built extraction system forms an end-to-end completely sealed unit. The DCS connects to the sanding machine with flexible tubing and uses special HEPA (High Efficiency Particulate Absorber) filters to clean the air in two stages. The two-step cyclonic separation process captures the tiny dust particles and pollutants that cause allergies and respiratory illness -- the particles that are so difficult to clean up after normal sanding.
Even the bag change is dust-free. The specially designed self-sealing bag system means no dust can escape when the bag is removed or emptied.
Bona DCS 70 -- the specifications
The Bona DCS 70 is the first machine of its kind to attain the highest possible "H" Classification according to the strict European Standard EN 603395-2-6. H-level filtration is deemed industrial strength and is the only classification standard considered capable of filtering toxic (carcinogenic) dust.

Better finish quality from a cleaner surface
The reason for sanding a floor is to get a good finish. Residual dust left after sanding stays in the air and settles back onto the floor. Microscopic particles get trapped under the finish, causing nibs, rough patches, and adhesion problems.
With dust-free sanding the finish goes onto a genuinely clean surface. The result is smoother, more consistent, and lasts longer. The end-to-end Bona DCS system has all the components to eliminate dust completely -- HEPA filtration arrests pollen and carcinogenic wood dust, the seamless bag system prevents dust leaks when changing, and the floor is ready for priming and finish application with no clean-up required.
The clean dust-free environment allows for a superior finish and a better end result. Doing the job cleaner also means doing it better.
