We have our products tested and certified by TÜV Nord in terms of suitability for allergy sufferers. The DAAB (Deutscher Allergiker- und Asthmaverbund e.V. (German Allergy and Asthma Association)) also recommends synthetic carpets for allergy and asthma sufferers. They also bear the "Blue Angel" seal of approval from the German Federal Environment Agency, which is recognized by environmentalists, because they are particularly low in emissions and protect health. Furthermore, carpets measurably reduce impact sound as well as sound levels and reverberation time.
