PURPOSE: A filter element is provided to reduce the amount of waste and environmental problems by decomposing a retainer part from a filtering part and reusing the retainer part. CONSTITUTION: A filter element includes a spunbond-based fleet filtering part(21), a cylindrical flexible bonding material(24), and flexible connecting materials(23, 25). The cross section of the spunbond-based fleet filtering part is star-shaped. The cylindrical flexible bonding material is arranged at the upper part and the lower part of the fleet filtering part. The flexible connecting materials are interposed between the cylindrical flexible bonding material and the fleet filtering part. A mesh-shaped cylindrical retainer part is detachably attached to the inner circumference of the fleet filtering part. |
