Yes. AiroDoctor WAD-M20 was tested in the ISO 16000-36:2018 test chamber procedure in March 2021 and was subsequently certified. This standard procedure evaluates the performance of air purifiers, testing the reduction rate of culturable bacteria in the air. AiroDoctor achieved a reduction rate of 99.9% here. As there is currently no air purifier ISO test procedure for the elimination of airborne viruses such as SARS-CoV-2, further test runs were carried out outside the ISO certification, but in the same test chamber and under the same test conditions. For this, the efficacy of the AiroDoctor was determined on surrogate viruses similar to SARS-CoV-2. Here, too, the AiroDoctor achieved a reduction rate of 99.9%.
