This collaborative project is between McGill University and Airpura Industries - a Canadian developer and global exporter of indoor air purifiers. Indoor air purifiers usually contain the following principal components: a filter and a sorbent, an air handler, and, sometimes, a catalytic element. This collaborative project aims to create new knowledge on how these components of indoor air purifiers interact with the three most problematic categories of indoor air pollutants: nano-aerosols, bioaerosols, and volatile organic compounds. The physical, chemical and biological processes inside indoor air purifiers involving these pollutants are poorly scientifically understood. This lack of knowledge is especially acute for more sustainable filters and sorbents under development: recyclable, biodegradable, and compostable. The project's results will facilitate the development and implementation of better performing, healthier and more sustainable indoor air purifiers. The advancements will deliver an edge over the global competition providing an economic benefit to Canada. The project will include: 1) the experiments investigating the physical, chemical and biological processes at the interfaces of indoor air purifier components and the traditional and novel sustainable filters and sorbents, 2) the investigation of the removal, deposition, transformations over the product lifespan, and generation in indoor air purifiers of bioaerosols, (nano)aerosols, and volatile organic compounds, 3) characterization of indoor air purifiers' effects on bioaerosols in the processed air, and 4) biological and non-biological contaminants' interactions and formation inside indoor air purifiers. Based on this project, Airpura is expected to upgrade its series of products for the domestic and export markets and emerge as a global leader in the sustainability of indoor air purifiers, including the product end of life stage, highly important for reducing the environmental impact of indoor air purifiers. Four highly skilled young professionals will be engaged in the project and trained in a rich collaborative research environment.

该合作项目由麦吉尔大学和加拿大室内空气净化器开发商和全球出口商AirPura Industries共同完成。室内空气净化器通常包含以下主要组件：过滤器和吸着剂、空气处理器，有时还包括催化元件。这个合作项目旨在创造关于室内空气净化器的这些组件如何与三种最有问题的室内空气污染物相互作用的新知识：纳米气溶胶、生物气溶胶和挥发性有机化合物。涉及这些污染物的室内空气净化器内的物理、化学和生物过程科学上知之甚少。对于正在开发的更可持续的过滤器和吸着剂：可回收、可生物降解和可堆肥，这种知识的缺乏尤为严重。该项目的成果将有助于开发和实施性能更好、更健康和更可持续的室内空气净化器。这些进步将带来在全球竞争中的优势，为加拿大带来经济利益。该项目将包括：1)研究室内空气净化器部件与传统和新型可持续过滤器和吸附剂界面上的物理、化学和生物过程；2)研究生物气溶胶、(纳米)气溶胶和挥发性有机化合物在室内空气净化器中的去除、沉积、转化和生成；3)表征室内空气净化器对处理后空气中生物气溶胶的影响；4)室内空气净化器内生物和非生物污染物的相互作用和形成。在该项目的基础上，AirPura预计将针对国内和出口市场升级其系列产品，并成为室内空气净化器可持续发展领域的全球领先企业，包括产品生命周期结束阶段，这对减少室内空气净化器的环境影响非常重要。四名高技能的年轻专业人员将参与该项目，并在丰富的协作研究环境中进行培训。
