Abstract

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.

当前和未来室内空气净化技术回顾

空气污染是导致人类死亡的最大风险，已成为全球关注的问题。全球人口平均有 90% 的时间是在室内度过的，因此，室内空气质量（IAQ）对人类健康的重要性凸显出来。无论是在农村还是城市，大多数家庭、办公室、餐馆和其他室内场所都面临着室内空气污染（IAP）问题。本综述首先阐明了室内空气污染对健康的影响分析，并对室外空气污染和室内空气污染进行了比较和区分。本文综合了对现有商用室内空气净化器的批判性研究，并通过全面的文献综述揭示了其局限性和弊端。然后，本文转向探索有望彻底改变室内空气净化的新技术。从先进的过滤器制造技术到再生光催化氧化技术，这篇综述概述了打造下一代室内空气净化器的可能性。同时，它还讨论了阻碍这些技术融入商业应用的挑战。

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.
