Corona disinfecting air filter systems

An air filter to inactivate viruses, the air filter comprising:

• a filter medium configured to inactivate viruses from an air stream flowing therethrough, the filter medium comprising:
• a first filter layer;
• an entrance support screen disposed adjacent to a first side of the first filter layer;
• an inner separator screen disposed adjacent to a second side of the first filter layer;
• a first copper wool medium disposed adjacent to the inner separator screen;
• a second copper wool medium;
• a non-copper, non-filtering metallic separator screen disposed between the first copper wool medium and the second copper wool medium, said separator screen operable to randomize airflow coming out of the first copper wool medium and into the second copper wool medium;
• and
• a frame configured to support the filter medium.

An air filtration system comprising:

• a first filter comprising copper configured to inactivate contaminants from an air stream flowing through a ventilation system;
• a first frame configured to direct the air stream through the first filter;
• a second filter comprising copper configured to inactivate contaminants from the air stream flowing through the ventilation system;
• a channel extending between the first filter and the second filter such that the first filter and the second filter are in fluid communication;
• and
• a non-copper metallic separator device positioned between the first and second filters configured to randomize the air stream flowing through the ventilation system between the first and second filters.

A method for removing or deteriorating airborne contaminants from air, the method comprising:

• providing and air filter comprising:
• a first copper wool medium configured to inactivate viruses from an air stream flowing therethrough;
• a second copper wool medium configured to inactivate viruses from the air stream flowing therethrough;
• a non-copper metallic separator disposed between the first copper wool medium and the second copper wool medium configured to randomize the airflow coming out of the first copper wool medium and into the second copper wool medium;
• assembling an elongate section onto each perimeter edge of the air filter, and joining the elongate sections by way of corner sections section to create a rigid frame;
• positioning the air filter within the air stream of a ventilation system;
• adjusting the rigid frame to direct the air stream to flow through the air filter;
• and
• wherein the degree of obstruction that the air filter imparts on the air stream flowing therethrough does not result in a significant increase in pressure drop.
