The Grade 413 filter PAPER is made of Cellulose. Paper filters are depth filters as are Quartz filters. PVC, PVDF, and PTFE MEMBRANES are surface filters. Membranes are 1um or smaller pore size. The filter on this page is a 20 inch x 20 inch sheet. Please email us at labsales@opticsplanet.com with your application and we will be better able to help.
