Viruses are very tiny microbial particles. They are less than .012 microns in size and are easily transmitted by air or touch. The masks that people are wearing to protect themselves from this virus. Unfortunately this is just not the case.
In order to remove viruses from the air you need some very special HEPA type filters. These are called SULPA filters. This stands for Super Ultra Low Particulate AIr or Absolute filters. These are used by the CDC and other medical clinics around the world. Most of the masks now worn by people for protection are not capable of removing any viruses and most bacteria. They are good for removing large dust particles. HEPA masks are available but very expensive and hard to breathe thru as the HEPA paper is very dense and creates a lot of air resistance.
Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985 and has a number of HEPA filter systems that are designed for residential, commercial, institutional and medical applications. Their portable unit is certainly one of the best on the market for reduction/removal of harmful airborne particulate including bacteria and some viruses.
