Fighting Viruses and Bacteria: Filtration that Removes 99.99% of Aerosols Carrying Viruses*

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 remove 99.99% of aerosols carrying viruses.*

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 with molecular filtration is so important.

The air scrubbers include multiple stages of filtration to effectively remove aerosols carrying viruses and bacteria.

Each piece of equipment includes:

1) A Pre-filter that catches large particles and removes them from the air.

2) Molecular filtration Patented§ molecular filtration media removes aerosols carrying viruses from the air, safely oxidizing the molecules, while removing toxic and harmful gases.

3) PuraWard Filter The PuraWard filter is protected from many viruses, bacteria, and mold using copper and silver ions.

4) A HEPA filter that cleans the air of particulates as small as 0.3 microns 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 remove 99.99% of aerosols carrying viruses.*

With proper air filtration, we can help address one of the factors impacting the spread of viruses and bacteria. To learn more about Purafil’s air filtration equipment, visit
