Indoor Air Quality What kind of Virus is COVID-19 (Coronavirus)? Viruses can be generally categorized in three groups by virus structure. This affects the effectiveness of disinfectants in killing the viruses. Enveloped viruses are easiest to kill. (An example is Influenza A Virus. Large, non-enveloped viruses are more difficult to kill. (An example is Rotavirus. Small, non-enveloped viruses are hardest to kill. (Examples are Rhinovirus and Norovirus. Coronaviruses are enveloped viruses, meaning they are one of the easiest types of viruses to disable with the appropriate product. A third-party laboratory documented Top Product Innovation's cold plasma generator technology, Phenomenal Aire™ as successfully disabling Norovirus at a rate of 93.5% in 30 minutes. In March of 2020 3rd party testing validated that bipolar ionization technology can disable the Human Coronavirus (229E). Similar results are anticipated for SARS-CoV-2 (COVID-19). Phenomenal Aire™ Cold Plasma Generator technology is designed for installation and use within a commercial building's Heating Ventilation and Air Conditioning (HVAC) system. Phenomenal Aire™ produces an electric field filled with highly charged ions. The ions act as a natural scrubbing agent for the air passing through the field. The scrubbing process (bipolar ionization) safely disables viruses and other harmful microorganisms. The ions created by Phenomenal Aire™ travel from the HVAC system into the occupant space where they continue to safely disable harmful microorganisms in the air and on high touch surfaces like tables, countertops, desktops, doorknobs and computer keyboards.
