+Schmitzi Posted February 13, 2016 Author Share Posted February 13, 2016 . yes, exactly what I wanted to say: "who really knows".... And that with "Ultra-Fine-Dust" just came up last year, here in Germany, beside to the discussions we have to the diesel-cars "Fine-Dust-Pollution" (I try to translate:) ) diesel-cars are "locked out" from downtowns here, if they don´t have these "Fine-Dust"-filters, and some scientist were loughing about now, because they say they do not prevent from/filter the Ultra-Fine-Dust And they told the same for laserprinters, where you also can buy this paperfilters.... I really don´t know what to believe, so best way for me seems to assume the worst.... Quote Link to comment Share on other sites More sharing options...
