Throughout the COVID-19 pandemic, Canadian public health advisors and politicians have shared mixed messages about the utility of portable air filters (PAFs) for mitigating the transmission of airborne infectious diseases. Some public health advisors and decision-makers have also suggested that PAFs are cumbersome or require expert advice. We take this opportunity to review evidence and address myths about PAFs. In short, PAFs are an important tool to help reduce the risk of transmission of airborne infectious diseases. Moreover, PAFs are relatively simple to use, and there is a variety of high-quality guidance available for their deployment. We share this science here with the expectation that, going forward, public health authorities will position PAFs appropriately in infection prevention and control plans for both health care and community settings.
