Abstract: A water-soluble, biodegradable filter medium for removing entrained solid and/or liquid particles from an air stream, and a method of use thereof are disclosed. The filter medium is a solid solution of starch and a biodegradable, water-soluble synthetic polymer. After use, the filter medium is disposed of in an environmentally sound fashion. In particular, the filter medium is dissolved in water and the solid and/or liquid particles collected thereon are removed from the resulting aqueous solution of starch and polymer by decantation and the polymer and starch biodegraded using a conventional biological water treatment process.
