Antimicrobial Filter Media With Zeolite Ions for Pathogen Control

The patent converts the harmful captured pathogens into a beneficial outcome by using antimicrobial agents embedded in the filter media to neutralize and eliminate the pathogens. The harmful biological contaminants that accumulate on the filter are transformed from a biohazard risk into a controlled situation where the pathogens are destroyed by the antimicrobial action, thereby resolving the contradiction between capturing pathogens and preventing biohazard risk.

The patent introduces antimicrobial agents as an intermediary substance within the filter media structure. These agents act as a mediator between the captured pathogens and the environment, continuously releasing antimicrobial compounds that neutralize pathogens on contact. This intermediary mechanism allows the filter to maintain high filtration efficiency while simultaneously eliminating the biohazard risk of captured contaminants.

The patent employs porous filter media structures that provide extensive surface area for particle capture while maintaining open pathways for airflow. The porous architecture allows submicron particles to be captured on the vast internal surface area without significantly blocking the flow channels, thereby achieving high particle capture efficiency while minimizing pressure drop and delaying premature filter blockage.

The patent uses composite filter media combining different materials with complementary properties - such as hydrophobic and hydrophilic components, or materials with different pore size distributions - to optimize both particle capture efficiency and airflow performance. The composite structure enables selective capture of submicron particles while maintaining sufficient permeability to reduce pressure drop.

The patent applies preliminary action by embedding antimicrobial agents within the filter media structure before the filter becomes contaminated. These pre-positioned antimicrobial agents are released upon contact with moisture from captured biological particles, creating a protective effect that prevents biological film formation and fouling before they can occur. This preliminary antimicrobial action maintains filter performance and prevents secondary emissions.

The patent ensures continuity of useful action through the sustained release of antimicrobial agents from the filter media over time. As moisture from captured particles triggers continuous antimicrobial release, the filter maintains its pathogen-neutralizing capability throughout its service life, continuously preventing biological fouling and secondary emissions rather than providing a one-time effect.
