The Science of HEPA Filters

If you want to get the actual virus particles out of your air (rather than just filtering out virus-carrying water droplets), you will need a HEPA filter. Human coronaviruses measure 0.1 to 0.2 microns, much smaller than your home air filter (or face mask) can capture. You can get HEPA air filtration at home (or at your restaurant or small business) with an Austin Air purifier. All Austin Air models include a medical-grade HEPA filter rated to capture "99.97% of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns." The models are further specialized for different air contaminants such as volatile organic compounds (VOCs), smoke, or allergens, but all Austin Air models are equipped with a HEPA filter.

The Allergy Machine and Bedroom Machine also include a HEGA filter, which captures virus particles in a different way.

If you don't get a HEPA, it is still worth replacing or upgrading your air filter. A filter rated MERV 8 will capture the dust that carries viruses, and filters rated MERV 13 can capture virus-carrying water droplets as well as dust and allergens.
