ABSTRACT:
The present invention relates to a filter element suitable for the purification of gas, in which spaces are constituted with porous spacer between plural membrane filters. Particles or dusts captured in the filter element of the present invention are prevented from rescattering under the impulsive pressure at the initiation or termination of the filtration, so that the high precision of the filtration can be achieved.
