  • Surface-enhanced copper filter for air purification and system and method for using
    Patent number: 11969679
    Abstract: A surface-enhanced copper filter for air purification and a filter assembly with a surface-enhanced copper filter composed, at least in part, of substantially pure copper. The surface-enhanced copper filter uses the anti-microbial and electrostatic properties of elemental copper to inactivate biological contaminants and remove biological contaminants and other pollutants from the air. Also disclosed is a system and method using a filter assembly having a surface-enhanced copper filter to purify air. The disclosed surface-enhanced copper filter can be used in a stationary or mobile HVAC system or in a mobile air purification system.
