Fighting Viruses and Bacteria: Filtration that Destroys on Contact

With growing concerns around the global pandemic, businesses around the world are innovating solutions to help limit the spread of the virus and keep our communities safe. As leaders in air filtration, Purafil has the knowledge and know-how to design viable solutions. We are using this expertise to create antimicrobial, multi-stage filtration systems that capture and destroy viruses and bacteria on contact.

As the world combats viruses and bacteria with facemasks and personal protective equipment (PPE), we must also consider other factors that could impact the spread. One such factor is air quality. A recent study indicates that unclean air can increase the risk of respiratory problems and increase the fatality rate by 15 percent.  Additionally, Harvard Medical School states that infectious viral particles can float or drift around in the air for up to three hours (Covid-19 Basics, Harvard Health) making air filtration another component to fight the spread.

When we consider crowded hospitals and medical facilities, air filtration becomes even more important. Indoor air can be up to 5x more polluted than outdoor air, and even with HEPA filters, deadly airborne viruses and bacteria can still thrive. This is why filtering air and destroying viruses and bacteria on contact is so important.

Purafil’s technology* has been shown to be effective against SARS, Influenza, H1N1 and airborne bacteria.1 The air scrubbers include multiple stages of filtration to effectively capture, remove and kill viruses and bacteria.

1) Pre-filter. This catches and removes large particles in the air.

2) Chemical filtration. Our patented antimicrobial chemical media enables an oxidation process that eliminates viruses and bacteria.*

3) Puraward fiber (PWF) technology. This fiber is embedded with copper and silver ions that have antimicrobial properties to destroy viruses and bacteria.*

4) HEPA filter. This final step fully cleans the air before releasing it back into the room.

 These air filtration systems are suitable for hospitals, medical facilities, laboratories, office buildings, and educational institutions. They come in a range of sizes and airflows to kill up to 99.98% of target viruses and bacteria for more efficient and complete removal.

With proper air filtration that kills viruses and bacteria, we can help address one of the factors impacting the spread of viruses and bacteria. Our antimicrobial, multi-layered air scrubbers are designed to do precisely this. To learn more about Purafil’s air filtration equipment, visit
