High-performance mask origin story
Masks have been identified as important for reducing transmission of COVID. While of unquestionable value, unfortunately many masks either fail to effectively filter out the virus (poor filtration efficiency) or allow large quantities of air to leak around the mask (poor fit). This has forced individuals to either accept using cloth masks with low performance or purchasing medical grade disposable surgical masks. The consequence of these decisions being either an increased risk of infection or contributing to the high volume of mask waste accumulating in the environment and landfills. At the beginning of the pandemic, CHEO researchers believed Ottawa needed a mask that was both reusable and high-performing and partnered with Dessuis and EcoEquitable.
What sets the Ottawa Mask apart? Safety and sustainability
Particle filtration: Recognizing the problem with poorly quality masks, the American Society for Testing and Materials (ASTM) recently released specifications for community (consumer) masks. The ASTM suggested that a high performing, or level 2, mask must meet or exceed 50% Particle Filtration Efficiency (PFE) when tested at 0.1 microns. The Ottawa mask well exceeds the 50% target, reaching up to 88% prior to laundering.
Washable/Re-usable: Importantly, the Ottawa Mask was designed to maintain high PFE after sterilization with soap and water. Testing demonstrated the Ottawa Mask PFE to be 72 - 77% after x30 and x50 washes.
Mask fit and comfort: Fit has been shown to be a significant factor in mask effectiveness. The Ottawa Mask has been through multiple rounds of testing, including input from dozens of CHEO health care providers. Designed with a moldable nose bridge and adjustable head strap the Ottawa Mask is not only comfortable, but able to effectively reduce the proportion of inhaled air that bypassed the filter. Quantitative fit testing performed at CHEO has demonstrated that by forcing air through the filter, the Ottawa Mask is able to achieve results similar to single use surgical masks designed for health care.
