Exposure to contaminants in indoor air represent the single largest environmental health risk for most Canadians. Despite this known risk, indoor environments are resistant to policy solutions owing to the practical challenges of regulating private indoor environments. There is also a motivation gap as most of the health risk is chronic and outcomes emerge decades after exposure complicating the alignment of costs and benefits. However, the COVID-19 pandemic has focussed attention on indoor air cleaning solutions including ventilation and filtration. This increased attention has created an opportunity to meaningfully advance the science and practice of indoor air cleaning as the public, industry, and government are paying attention in a manner not seen historically. There are also new challenges including the proliferation of air cleaning technologies that are at best not effective and at worst harmful because of the emission of oxidants, byproducts and/or ions. The proposed research has the programmatic objectives of developing new scientific knowledge in the area of air cleaning and advancing the use of and motivation for air cleaning that will engage the public and decision makers and lead to a sustainable future for effective air cleaning technologies and techniques. An underlying aspect is the consideration of equity. In much of the world, safe indoor air is a commodity that is available to some but not to others. This project proposes an alternate framework where innovative air cleaning approaches are used as part of a strategy to address societal disparities. This research program is organized around four integrated short-term objectives. 1)Development and validation of an in-situ test for air cleaning approaches 2)Development of a measurement approach for total particle removal in an environment 3)Design and testing of new control strategies to optimize the performance of air cleaners 4)Assess the relationship between air cleaning and cognitive performance and decision making These objectives are all focussed on overcoming important barriers to the increased use of air cleaning and share several common elements including the use of low-cost pollutant sensors to ensure wide adoption, the inclusion of the importance that the indoor environmental context has on air cleaning performance, the consideration of primary and secondary impacts, the use of machine learning approaches to improve analysis and performance, and the reliance on interdisciplinary approaches to achieve goals. This research program will also train HQP in indoor air measurement, assessment, and improvement that are clearly needed in Canada. The outcomes from these objectives will be novel contributions to the field that allow specific air cleaning approaches to be appropriately valued and make air cleaning more reliable, effective, and available to all.

对大多数加拿大人来说，暴露于室内空气中的污染物是最大的环境健康风险。尽管存在这种已知的风险，但由于管理私人室内环境的实际挑战，室内环境对政策解决方案具有抵抗力。也存在动机差距，因为大多数健康风险是慢性的，结果在暴露几十年后出现，使成本和收益的匹配复杂化。然而，新冠肺炎疫情使人们的注意力集中在包括通风和过滤在内的室内空气净化解决方案上。随着公众、行业和政府以一种历史上未曾见过的方式关注，这种日益增长的关注创造了一个机会，有意义地推进室内空气净化的科学和实践。还存在新的挑战，包括空气净化技术的扩散，这些技术充其量是无效的，最坏是有害的，因为氧化剂、副产品和/或离子的排放。拟议研究的方案目标是在空气净化领域发展新的科学知识，促进空气净化的使用和动机，使公众和决策者参与进来，并为有效的空气净化技术和技术创造一个可持续的未来。一个根本的方面是对股权的对价。在世界上许多地方，安全的室内空气是一种商品，一些人可以获得，而另一些人则不能。该项目提出了一个替代框架，其中创新的空气净化方法被用作解决社会差异的战略的一部分。这项研究计划围绕四个综合短期目标进行组织。1)开发和验证空气净化方法的现场测试2)开发环境中总颗粒物去除的测量方法3)设计和测试新的控制策略以优化空气净化器的性能4)评估空气净化与认知性能和决策之间的关系这些目标都集中在克服增加使用空气清洁的重要障碍上，并共享几个共同的元素，包括使用低成本的污染物传感器以确保广泛采用，包括室内环境环境对空气净化性能的重要性，考虑一次和二次影响，使用机器学习方法来改进分析和性能，以及对跨学科方法的依赖以实现目标。该研究计划还将对HQP进行室内空气测量、评估和改进方面的培训，这些显然是加拿大需要的。这些目标的成果将是对该领域的新贡献，使特定的空气净化方法得到适当的重视，并使空气净化更加可靠、有效和可供所有人使用。
