Evaluating the Efficacy of the MedicAir Air Purifier in Reducing Ambient Air Pollution in Classrooms

In light of the novel coronavirus and transmission in schools, increased scrutiny has been placed on airborne viral and particulate contamination, and efforts to mitigate this have been suggested, including the use of air purification. The importance of this is increased given the relationship between increased airborne particulates and increased coronavirus transmission, as well as the significance of removing particulates in the size range of bacteria and viruses from the air. Ambient levels of pm2.5 and pm1 in the absence of purification were recorded in two classrooms of similar size using medical grade data loggers, which then measured the change in these levels with use MedicAir air purifiers. It was found that baseline levels at times doubled the WHO limits for safe IAQ- MedicAir units were able to rapidly reduce levels of particulates to significantly below guidelines. We propose that the use of these units is an effective and rapid solution for the mitigation of coronavirus transmission, as well as the improvement of IAQ in schools.
