Every step taken on hard flooring kicks up a cloud of dust and fine particles. When breathed in over a long period of time, these are harmful to health. Carpets, on the other hand, have proven themselves to be real dust magnets, filtering the unwanted particles from the air and binding them to the fibres. Carpets trap the dust until it is vacuumed. This is not only smart, but can even be measured. The guideline amount for maximum dust accumulation in the air stands at 50 µg per cubic metre. For smooth surfaces such as parquet flooring, PVC, linoleum and marble, this figure averages 62.9 µg per cubic metre – well above the guideline amount. In rooms with carpets, however, the dust accumulation comes in at 30.4 µg per cubic metre. This figure is not only well below the accepted maximum threshold, but also less than half the level observed in rooms with smooth flooring. In practice, this means no clouds of dust and fine particles swirling around the room. In turn, this eases the strain on the airways, which is a big plus for allergy sufferers, as shown by a 2005 study published by Deutsche Allergie- und Asthmabund e.V.
