Virucidal air filter
The PuraWard air filter is made of high-performance fibers with built-in copper and silver ions that attack bacteria and viruses together. Copper ions attack the amino acids of the cell membrane or viral envelope, allowing silver to enter the interior. Copper and silver then react with the basic enzymes and cause significant damage and destruction of the microorganism.
PuraWard has been successfully applied to air filters and respirators approved by the US FDA for their antibacterial and antiviral properties in surgical environment. The antimicrobial efficacy of PuraWard against Sars-CoV-2 virus as well as other viruses and bacteria has been documented in relevant studies.
Applications: Used in any existing or new central type air conditioning system or in local air filtration units. Particularly applicable to hospitals, clinics, health care facilities, schools and educational institutions, shopping malls, office buildings, hotels, airports, means of transportation (buses, trains, ships).
