Advanced Filter Tester for Size Resolved Penetration Measurements
Ondráček, Jakub ; Zíková, Naděžda ; Ždímal, Vladimír
Aerosol filtration is the most widely used process to capture aerosol particles. It is used in various applications throughout the different areas of interest (emissions cleaning, occupation safety and health, air-conditioning, etc.). In most of these applications, it is useful to have information about penetration, or filtration efficiency, of the chosen filtration material. Information available from filter manufactures, a background of a decision on which filter to use for the specific purposes, is usually not detailed enough. Therefore, new, fully controlled filter testing instrument was developed and thoroughly tested, providing a size-dependent penetration; proving a very good precision and reproducibility of the results. Using this instrument we have measured several commercial filter materials including standard filters (Whatmann, Milipore, Pall) and personal respirators (e.g. 3M).
