Presents the germ filtering efficiency of high efficiency filters abroad. Through giving off the germ in front of the return air inlet with a high efficiency filter in an isolation ward, calculates the germ filtering efficiency of B and C type filters respectively. Proves that when return air inlets fitted with high efficiency filters, the circulation air can be partly used in isolation wards.
