Metal rubber, which has a series of excellent properties, is combined with both metal and rubber’s characteristics. By means of VHX-600super field depth three-dimensional microscope and HPCA-2portable analyzer of contamination, the filtrating experiments about chocolate milk samples were carried out using metal rubber cylindrical filter elements with different structure parameters. The broken line graph about the chocolate milk’s pollution level before and after filtering was obtained through changing porosity, wire diameter, and thickness of the specimen shape. And the decrease of porosity and wire diameter as well as the increase of thickness could improve the filtering performance of materials, which was obtained through the horizontal and vertical comparison of the broken line graph.
