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.
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 spores. Statistical analysis was performed using SPSS 26.0; values < 0.05 were considered statistically significant.
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 spp. spores significantly decreased.
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.
生物气溶胶可能对健康构成威胁。在 SARS-CoV-2 大流行期间，便携式设备在不同环境中得到了应用，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设备“AEROK 1.0”在正常活动期间减少室内空气中微生物、颗粒物和花粉空气污染物的有效性。
在行政室内，使用主动（DUOSAS 360 和 MD8）和被动采样法测量空气中的微生物污染；使用粒子计数器评估粒子浓度；使用 Hirst 型花粉陷阱评估空气中的花粉和孢子。使用 SPSS 26.0 进行统计分析；<0.05 被认为具有统计学意义。
两种不同采样器评估的空气中细菌污染分别降低了 56%和 69%。被动采样评估的空气中细菌污染降低了 44%。对于真菌，主动采样的减少率为 39%。空气中的颗粒物（直径≥1.0、2.0μm）以及总花粉和 spp 孢子的室内/室外浓度比值显著降低。
结果突出了 AEROK 1.0 降低空气中污染的有效性。所进行的方法为评估用于空气消毒的设备的有效性的标准化模型的定义提供了贡献。
