Wildfire smoke shows need for better ventilation in public spaces

"...Regulations on air quality vary across federal and provincial jurisdictions but none mandate the use of high efficiency particulate air – or HEPA – filters, or those that have a minimum efficiency reporting value of 13 – termed MERV-13 – or higher. Many organizations are opting to improve their ventilation systems, but Fox believes high-quality filters should be a requirement, not a suggestion.
