Abstract: The great majority of sterile products commercially available as well as prepared in compounding pharmacies are sterilized by sterile filtration during aseptic processing. This brief and basic review will highlight the nature, action, and use of sterilizing filters. Special emphasis is given to how filters are validated in producing a sterile filtrate while being compatible with the filtered solution, as well as how filters are integrity tested during aseptic processing.
