, Filtration does not kill microbes, it separates them out.
Membrane filters with pore sizes between 0.2-0.45 μm are
commonly used to remove particles from solutions that can't
be autoclaved.
It is used to remove microbes from heat labile liquids such
as serum, antibiotic solutions, sugar solutions, urea solution.
Various applications of filtration include removing bacteria
from ingredients of culture media, preparing suspensions of
viruses and phages free of bacteria, measuring sizes of
viruses, separating toxins from culture filtrates, counting
bacteria, clarifying fluids and purifying hydrated fluid.
Filtration is aided by using either positive or negative
pressure using vacuum pumps.
The older filters made of earthenware or asbestos are
called depth filters.
