So far the first vacuum cleaner filter does its job well. It seems to me that your request for a review is a bit premature. The company fulfilled my order promptly. I appreciate it very much. Can't see how the suction affects the filter other than it doesn't seem to reduce the vacuum's suction. Perhaps Revane, or whoever is writing the questions, should reconsider this question. I see that Revain will not accept my submission score until I answer this question.
