Filter Sterilization

Dear Kev,
Filters don't sterilize, they disinfect by trapping microbes larger than
their pore size. Standard biological filters in the 0.45 um to 0.22 um
range are capable of trapping most bacteria, the exceptions being
relatively small forms such as mycoplasmas. These filters will not trap
viruses. I hope this helps.
