Dust is normally quite harmless and leaves nothing more than a fine coat on our polished surfaces. However, there is a sinister side to dust as dust can be comprised of any substance, which includes those harmful to humans. Dust is made up of minute particles from the size of a micron or two (a thousand of which make a millimetre) to much larger particles. The larger, weightier particles often settle quickly but smaller particles can float indefinitely in the air.
