Seit einigen Wochen sind wir sehr glücklich darüber, die Active Coating Beschichtung zu haben. Frische, klare Luft im ganzen Haus, die Augen-Trockenheit ist komplett weg. Für Tiere Besitzer sehr empfehlenswert, da die Gerüche viel schneller verfliegen. Wir sind begeistert!(Translated by Google) For a few weeks now we have been very happy to have the Active Coating coating. Fresh, clear air throughout the house, the dryness of the eyes is completely gone. For animal owners very recommendable as the smells evaporate much faster We are excited!Marketa Sura
Wir haben die Beschichtung Active Coating seit ca. 3 Wochen Zuhause. Das Ganze ist einfach nur genial. Obwohl öfter kein Fenster geöffnet ist, hat man den Eindruck das doch eins offen steht. Die Luft ist klarer und reiner. Unangenehme Gerüche jeglicher Art verschwinden viel schneller. Auch ist dadurch die Pollenbelastung im Wohnraum bedeutend geringer und mein Heuschnupfen ist so gut wie nicht spürbar. Diese Beschichtung kann ich nur jedem Empfehlen .Steffen P. aus Gersthofen(Translated by Google) We have had the Active Coating coating at home for about 3 weeks. The whole thing is just awesome. Although often no window is open, one has the impression that one is open. The air is clearer and cleaner. Unpleasant smells of all kinds disappear much faster. This also significantly reduces the pollen load in the living room and my hay fever is barely noticeable. I can only recommend this coating to everyone.Steffen P. from GersthofenSteffen Paul
Seitdem PURE AIR vor ein paar Wochen bei uns auf die Fenster beschichtet wurde, ist mein Heuschnupfen zu Hause quasi weg. Für mich eine absolute Erleichterung, da ich oft nachts schlecht Luft bekommen habe und tagsüber viel niesen musste. Auch Gerüche nach dem Kochen sind viel schneller verflogen, als noch vor ein paar Wochen. Wir sind absolut zufrieden.(Translated by Google) Since PURE AIR was coated on our windows a few weeks ago, my hay fever at home has almost disappeared. It was an absolute relief for me, as I often had difficulty breathing at night and had to sneeze a lot during the day. Even smells after cooking evaporated much faster than a few weeks ago. We are absolutely satisfied.Julia Moessle
