A membrane filter is a matrix with channels which act as a screen and retain particles larger than the filter on the surface of the
membrane. Membrane filters allow the retention of sub-micron particles and organisms.
Note that pores have not been observed in RO or NF membranes using a microscope.
Filtration definitions and relative pore size
MF 0.1 - 5.0 micron
UF 0.01-0.1 micron
NF, RO 0.001 (theoretical)
