FILTER FOR AIR CLEANER

摘要

PURPOSE:To prevent the movement of a granular deodorizing filter medium with a rib by providing the rib obtained by adding a hot-melt material to a corrugated dust-protective filter medium in which a deodorizing filter medium is provided in its valley. CONSTITUTION:A granular deodorizing filter medium 2 is packed in the valley on one side of a corrugated air-permeable dust-protective filter medium 1. An air-permeable-sheet cover 4 is fixed on the peak of the mountain on one side of the filter medium 1 to cover the filter medium 2. Furthermore, the rib 10 obtained by adding a hot-melt material is formed on the filter medium 2 side of the filter medium 1 in the direction orthogonal to the ridgeline of the mountains of the filter medium 1. The movement of the filter medium 2 is prevented by the rib 10.
