AIR FILTER COMPRISING COPPER-BASED MAGNETIC ALLOYS FOR REDUCING MICROORGANISMS IN POLLUTED AIR, AND PRODUCTION METHOD THEREOF

摘要

Disclosed is an air filter comprising copper-based magnetic alloys, which is useful for reducing microorganisms suspended inside hospital facilities and other enclosed spaces with a high microbial load density. The air filter comprises porous plates of copper-based magnetic alloys of the type Cu-Co-Fe, wherein the alloying agents Co and Fe are present in an amount of 5-10% w/w Co and 5-10% w/w/ Fe, or of the type Cu-SmCo5, wherein the alloying agent SmCo5 is 10-15% w/w. Also disclosed is a production method comprising the steps of: obtaining the magnetic alloys by means of mechanical grinding; compacting the porous plates of copper alloys; and preforming by compaction of the porous plates.
