Abstract

A system for sanitizing and filtering air includes a chamber through which air passes, the chamber containing an ultraviolet light source. A sanitizing filter is removably mounted in the chamber, the filter containing a mechanical filtration media and a photocatalytic agent. The ultraviolet light illuminates the photocatalytic agent, and air passing through the chamber is purified by the photocatalytic agent and filtered by the mechanical filtration media. The system may also ionize the air, thereby polarizing particles in the air. When the polarized particles are caught in the filter they polarize the filter media, causing it to electrostatically attract other polarized particles in the air, thereby improving its filtration efficiency.
