While HEPA and other standard air filters go down to 0.3 microns, viruses are 100 times smaller than bacteria and are typically at 0.004 to 0.1 microns in size. By comparison, that is 3 to 75 times smaller than what available filters can treat.
Micron Pure™ is designed to be effective at inactivating viruses at this tiny scale (SARS-CoV-2 is approximately 0.125 microns). It continuously treats air to inactivate airborne pathogens in hospitals, offices, public spaces, and homes. 3rd party testing of the initial prototype unit at ARE Labs showed >99.99% removal of all particles even those just 1⁄2 the size of SARS-CoV-2. Testing at MRIGlobal showed a 99.97% inactivation of live SARS-CoV-2 (the virus that causes COVID-19).
