Statutory framework conditions apply to various dust classes. These are described in the international standard IEC 60 335-2-69, which classifies dust into three different dust classes: L, M, and H.

Dust Class L:
Ordinary and harmless dust, such as household dust, and ordinary and harmless materials, such as soil.

Dust Class M:
All wood dust, as well as dust from putty, fillers, and varnishes; plaster; cement; concrete; tile adhesive; and paints (e.g., latex and oil-based paints); or materials containing silica, such as sand and pebbles. 

Dust Class H:
Carcinogenic dust, dust containing carcinogenic and pathogenic particles, as well as dust containing fungal spores, asbestos, mineral fibers, asphalt, and synthetic mineral fibers, such as glass wool.

 So what exactly does this mean?

 For all types of dust harmful to health, there are strictly defined workplace limit values (AGW) in mg/m³ of air within the dust classes. This standard divides dust into three classes: L, M, and H. The workplace limit value (AGW) specifies the maximum concentration of dust in the air we breathe at which no health problems are expected, even during prolonged exposure (eight hours a day, five days a week). The lower the AGW value in mg/m³ of air, the more hazardous the dust is and the greater the health risk.

Now all you have to do is choose the container size and the necessary vacuum cleaner accessories, and you can start vacuuming.
