Abstract
Three 3.0m polycarbonate track-etched filters were used in series in a 37 mm cassette and tested at 2.2 L/min using an automated filter tester to determine the filter assembly’s deposition curve as a function of particle size from 0.03 to 0.4 m. The filter assembly’s efficiency curve was compared to Stahlhofen’s resting with nose breathing and working with mouth breathing human total lung deposition curves used by the ICRP. Bias maps show that the shape of the filter assembly’s deposition curve matches the two lung deposition curves in the ultrafine range under these specific test conditions. The efficiency curve of the three 3.0m polycarbonate filters at 2.2 L/min was compared to the efficiency curve of the same configuration at 1.5 L/min. It was shown that a flow rate of 2.2 L/min more closely mimics the ICRP deposition models than a flow rate of 1.5 L/min in the ultrafine range.
