Returned
Tried many filters and these were the worst yet, first off they had different size o-rings in them, so one had no draw and the other had a draw without trapping any tar. Also looks better in the picture. Total rip off, if only people cared enough to make a quality product so much time would not be wasted returning stuff. So far the Sanda Wood Reusable Circulating Filter Direct Pull Reduce Tar Smoke Cigarette Holder is best, if you don't mind cleaning it after 3 or 4 cigarettes.
