This Technical Report was prepared by members
of the PDA Virus Filtration Task Force.
This technical report addresses virus removal filters that retain viruses
by a size exclusion mechanism. It explains how they work, recommends how to
elect the best filter for various applications, physical and biological characterization
and test methods, and validation. The 2008 revision expands the original report
to cover best practices for filter qualification and validation of filters
designed to remove viruses 20 nm in diameter and larger.
