Fitted carpets: Advantages for allergy patients

The health magazine of DAAB (Deutscher Allergie- und Asthmabund e.V.) gives detailed and interdisciplinary information about themes like “allergies”, “asthma”or “neurodermatitis”to patients, relatives or physicians. The findings of a study, already conducted by DAAB in 2005 found that the level of fine dust matter is much lower in carpeted areas as in a non-carpeted environments.

Smooth flooring or textile floor coverings?
So far, the answer has divided allergy patients, doctors and scientists into two camps. A study commissioned by the DAAB shows: Using a smooth flooring markedly increases the risk of finding an increased fine dust load in indoor rooms, while using fitted carpets minimises this risk. The article “Better carpets” deals with fine dust load in the indoor air and gives clear preference to textile floor coverings.
The average fine dust concentration in indoor rooms equipped with smooth flooring material is twice as high as in indoor rooms equipped with carpet tiles or wall-to-wall carpets. With 62.9 μg/m³, the arithmetic mean value of the fine dust concentration in rooms with smooth flooring clearly exceeds the limit value of 50 μg/m³, whereas in households with fitted carpets the mean value amounts to 30.4 μg/m³ and is thus substantially lower than the limit value.
When individual rooms are considered, the limit value is exceeded in some cases. This, however, is due to other marginal parameters such as smoking, pets, kind and frequency of cleaning, activities in the rooms, etc. Above all for particularly sensitive persons already suffering from previous damage to their airways, the selection of textile floor covering (e.g. flooring material binding dust) and not emitting it to the air to be breathed is an essential preventive aspect.
Fine dust is a big problem especially for allergy patients. Irrespective of the kind of the dust inhaled, the particles as such, with their mechanical effect, cause irritation when they enter the respiratory tract. Where the bronchial system has previous damage, this effect will be so much the stronger. Moreover, we find other pollutants bound to these particles, e.g., allergens which, in this manner, may get deep down into the lungs where relevant reactions may be caused.
The quality of the outdoor air has continuously improved up to the present day. This is the consequence of scientific findings and the resulting laws and regulations made to protect man. This is also the core of what the fine dust discussion is aiming at.

From the point of view of DAAB and also from the Society for Environmental and Indoor Room Analysis (GUI), indoor rooms – where we spend more than 90 per cent of our lifespans – are given too little attention.
