Abstract

Background: Bioaerosols can represent a danger to health. During SARS-CoV-2 pandemic, portable devices were used in different environments and considered a valuable prevention tool. This study has evaluated the effectiveness of the air treatment device "AEROK 1.0^®" in reducing microbial, particulate, and pollen airborne contamination indoors, during normal activity.

Methods: In an administrative room, airborne microbial contamination was measured using active (DUOSAS 360 and MD8) and passive sampling; a particle counter was used to evaluate particle concentrations; a Hirst-type pollen trap was used to assess airborne pollen and Alternaria spores. Statistical analysis was performed using SPSS 26.0; p values < 0.05 were considered statistically significant.

Results: The airborne bacterial contamination assessed by the two different samplers decreased by 56% and 69%, respectively. The airborne bacterial contamination assessed by passive sampling decreased by 44%. For fungi, the reduction was 39% by active sampling. Airborne particles (diameters ≥ 1.0, 2.0 μm) and the ratio of indoor/outdoor concentrations of total pollen and Alternaria spp. spores significantly decreased.

Conclusions: The results highlight the effectiveness of AEROK 1.0^® in reducing airborne contamination. The approach carried out represents a contribution to the definition of a standardized model for evaluating the effectiveness of devices to be used for air disinfection.

铜静电过滤系统 "Aerok 1.0 "在空气消毒方面的效果研究。

背景：生物气溶胶可对健康造成危害。在 SARS-CoV-2 大流行期间，便携式设备被用于不同的环境，并被认为是一种有价值的预防工具。本研究评估了空气处理装置 "AEROK 1.0®"在正常活动期间减少室内空气中微生物、微粒和花粉污染的效果：在一间行政办公室内，使用主动采样（DUOSAS 360 和 MD8）和被动采样测量空气中的微生物污染；使用颗粒计数器评估颗粒浓度；使用赫斯特型花粉捕集器评估空气中的花粉和交替孢子。使用 SPSS 26.0 进行了统计分析；P 值小于 0.05 视为具有统计学意义：结果：两种不同采样器评估的空气细菌污染分别减少了 56% 和 69%。被动采样法评估的空气细菌污染减少了 44%。在真菌方面，主动采样减少了 39%。空气中的颗粒物（直径≥ 1.0 和 2.0 μm）以及室内/室外总花粉和 Alternaria spp：结果表明，AEROK 1.0® 能有效减少空气污染。所采用的方法有助于确定评估空气消毒设备有效性的标准化模型。

期刊介绍： International Journal of Environmental Research and Public Health (IJERPH) (ISSN 1660-4601) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes, and short communications in the interdisciplinary area of environmental health sciences and public health. It links several scientific disciplines including biology, biochemistry, biotechnology, cellular and molecular biology, chemistry, computer science, ecology, engineering, epidemiology, genetics, immunology, microbiology, oncology, pathology, pharmacology, and toxicology, in an integrated fashion, to address critical issues related to environmental quality and public health. Therefore, IJERPH focuses on the publication of scientific and technical information on the impacts of natural phenomena and anthropogenic factors on the quality of our environment, the interrelationships between environmental health and the quality of life, as well as the socio-cultural, political, economic, and legal considerations related to environmental stewardship and public health. The 2018 IJERPH Outstanding Reviewer Award has been launched! This award acknowledge those who have generously dedicated their time to review manuscripts submitted to IJERPH.
