What you get sent, is an 8-way folded and vacuum packed, carelessly torn from the roll fleece. Therefore, the mass does not agree - in length were missing in my 3cm. After opening it unfolds though largely, but then comes far closer to the twice as thick, about 1.3 cm, from the hardware store - cost eg in OBI Two Pack 2.29. The whole thing fits into a A5 letter from 3mm thick! Thought at first already, they sent me something completely wrong. He's so thin and coarse "meshed" as a floor cloth has for one euro a better filter effect! The reviewers with 5 stars must either have the filters ready to get or do not know better. Is certainly a mystery to me! Right condition: photos-upload (*) net / view / linksamazonrm74ret19j3.jpg The seller was positive with 93%. One probably. send the other two to the original image?
