Review of Current and Future Indoor Air Purifying Technologies
Air pollution poses the greatest risk of death for humans and has become a global cause of concern. The global population spends an average of 90% of their time indoors; therefore, the significance of indoor air quality (IAQ) on human health comes to the forefront. Most households, offices, restaurants, and other indoor places, whether in rural or urban areas, are facing the problem of indoor air pollution (IAP). This review begins by elucidating the health impact analysis of IAP and drawing parallels and distinctions between outdoor and indoor air pollution. This paper synthesizes a critical examination of existing commercial indoor air purifiers and sheds light on their limitations and drawbacks through a comprehensive review of the literature. The review then pivots toward the exploration of new technologies poised to revolutionize indoor air purification. From advanced filter manufacturing techniques to regenerating photocatalytic oxidation, this review outlines the possibilities to shape next-generation indoor air purifiers. Simultaneously, it discusses challenges holding back the integration of these technologies into commercial applications.
期刊介绍：
ACS ES&T Engineering publishes impactful research and review articles across all realms of environmental technology and engineering, employing a rigorous peer-review process. As a specialized journal, it aims to provide an international platform for research and innovation, inviting contributions on materials technologies, processes, data analytics, and engineering systems that can effectively manage, protect, and remediate air, water, and soil quality, as well as treat wastes and recover resources.
The journal encourages research that supports informed decision-making within complex engineered systems and is grounded in mechanistic science and analytics, describing intricate environmental engineering systems. It considers papers presenting novel advancements, spanning from laboratory discovery to field-based application. However, case or demonstration studies lacking significant scientific advancements and technological innovations are not within its scope.
Contributions containing experimental and/or theoretical methods, rooted in engineering principles and integrated with knowledge from other disciplines, are welcomed.
