Abstract：In order to solve the problem of massive nano-sized aerosols go ing into environment produced by manufactured nano-materials， endan gering the environment and human health， the properties and origin of nanosized aerosol were mainly summarized. Then the situations and the impacting parameters for scavenging nano-sized aerosol were presented. The research orientations of combination of coagulating technique and fil tration technique for scavenging nano-sized aerosol were brought forward. The design method was provided， guiding the choice for scavenging nano-sized aerosol.
