In December, the Alberta Chapters of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers released guidance recommending that schools have ventilation systems that use filters with minimum efficiency reporting values of 13 or higher to try and make indoor learning as safe as possible for staff and students during the COVID-19 pandemic. These are also known as MERV-13 filters or systems. Edmonton Catholic Schools are now in the process of having MERV-13 systems installed. Edmonton Public Schools, according to the superintendent, are looking at options, and have issued a request for vendor proposals for additional room air purifiers.
