Adhesion is good on the adhesive side, but there is also adhesive residue on the dust side, so dust remains after direct contact with vacuuming the net. While it still looks dusty, the remaining layer of dust shouldn't cause significant airflow resistance. Apart from that, by just covering the air intakes, I was able to fit a 200mm fan, an 18x26cm fan hole on the side of my PC case and 2x14x14cm fan holes and under the PSU on the bottom of the case cover. In general, "dusty appearance" does not bother, the product is good. However, they could make it wider as they had to use multiple pieces of mesh to cover areas larger than 15cm.
