RAPID STERILIZATION OF AN AIR FILTER MEDIUM

摘要

A method and apparatus (10) for sterilizing a filter medium (14) includes th e steps of providing a filter element (14), an atmospheric plasma device (12) capable of generating and convecting reactive oxidative species, and locatin g the filter element (14) downstream of the plasma device (12) whereby both th e surface and the bulk of a filter media (14) is exposed to the reactive oxidative species generated from the atmospheric plasma effecting sterilization of the filter element (14). The atmospheric plasma device (12) is either an RF, a DC pulse, or an AC power supply to generate the atmospher ic plasma and create the reactive oxidative species.
