Development of a procedure to measure the performance of ventilation filters for nanoparticles

Abstract

Abstract Filtration is a simple and effective way to capture particles of different sizes used in different workplaces. However, the state of current knowledge has shown that the performance of entire filter depending on the particle size are still very limited. The main objective has therefore been to develop a procedure to evaluate the filter performance used in ventilation systems for particles smaller than 300 nm including nanoparticles. The measurement procedure has been validated by comparing the penetration measurements on two different setups for nanoparticles.
