Bacterial filter is a kind of filter, generally less than 0.22 micron pores, should be able to filter bacteria.

Bacteria have a certain size. If the filter membrane or filter column (or other) has a pore size smaller than the diameter of the bacteria, then when the liquid or gas passes through, the bacteria will be blocked, and the past liquid will not pass. Or the gas is sterile.

However, the virus can pass through bacterial filters because of its tiny structure, which is on the order of nanometers.
