1. A tubular filter that absorbs ethylene or other gases for refrigerated transport containers, formed by a cylindrical tube of plastic mesh (2), closed at both ends with respective hermetic caps (3), which internally incorporates granulated materials that absorb ethylene or other gases, characterized by said plastic mesh (2) having a structural configuration which facilitates the entry of air flow into the cylindrical tube, being formed by the combination of an inner crown (20) formed by a filament having a circular section (201), and an outer crown (21) formed by a filament having a wing-shaped section configuration (211), wherein a circular base thereof is wider than a distal end thereof, thereby facilitating the entry of air flow into the tube.
