The formulation used in the mini fogger product has been independently tested in order to measure its antiviral performance (efficacy). The two test methods used were the International Standards termed EN 14476 and EN 16777. The viruses used by the laboratory in testing are specified by these Standards to represent a wide group of medically important viruses (it’s not possible to test everything). A product passing these tests can be considered to possess broad spectrum antiviral properties. Importantly, the Hycolin Antiviral Mini Fogger exceeded the PASS thresholds of the tests (i.e., reduced the virus number by more than 99.99%) so it can legitimately claim excellent, broad spectrum antiviral efficacy. Within the range of viruses that are captured by the results of this test are the Coronaviruses, hence the ‘Kills Coronavirus’ claim. In addition to testing against the test viruses described here, the mini fogger product has been tested against a virus called Feline Coronavirus – a member of the actual Coronavirus group of viruses. Results were excellent, i.e., in excess of 99.99% of this virus killed on contact with the mini fogger.
