    It is known that the ultra-fine dust is fatal to human health, and HEPA filter is one of the efficient ways to remove it at home, office and etc. The present work studied the variation of HEPA filter performance(pressure drop, dust collection efficiency and etc.) as ultra-fine dust under 0.3μ was accumulated on the filter and the characteristic difference from the results of the regular test dust whose diameter ranges from 0 to 100μ. Incense smoke was used to generate the ultra-fine dust for the test. Generally it is known that as the regular test dust is accumulated on a filter pressure drop increases and dust collection efficiency of the filter remains constant or increases. However It was fount that the accumulation of ultra-fine dust on HEPA filter resulted in a considerable reduction in the dust collection efficiency while the pressure drop remains almost constant, which is quite different from the results of regular test dust.
