Traffic-related ultrafine particle pollution near highways is associated with adverse health. Reducing exposure by use of portable air purifiers in homes is one approach to reducing this risk. However, the reaction of residents to having air purifiers in homes is not well studied.
Within the framework of our randomized crossover trial of air purifiers in homes near a major highway, we collected data about participants' use and reactions to air purifiers using questionnaires at their 30-day and 90-day home visits, recorded electricity consumption using HOBO monitors, and conducted structured interviews with participants.
Nearly all 150 participants reported running the air purifiers virtually 24 h every day in both their living room and their bedroom in the prior month. The units' HOBO electricity use, from a subset of 45 participants, supported the participants' responses from the questionnaire. Approximately 80% of participants reported setting their air purifier on the medium setting. Tolerance to air purifier noise increased significantly between the 30-day and 90-day home visits, with approximately two thirds reporting not being bothered at all by the noise. The qualitative interviews in a subset of 26 participants yielded consistent responses to those from the questionnaires. Size of unit, airflow, and energy consumption were additional concerns that emerged during the interviews.
Results from the questionnaires, HOBO data, and structured interviews all suggest participants had positive reactions towards the presence of in-home APs, and therefore may be receptive to using air purifiers in their homes on a regular basis.

高速公路附近与交通相关的超细颗粒污染与健康不良有关。在家中使用便携式空气净化器减少暴露是降低这种风险的一种方法。然而，居民对在家中使用空气净化器的反应尚未得到充分研究。
在我们关于在主要高速公路附近的家中使用空气净化器的随机交叉试验框架内，我们使用问卷在 30 天和 90 天的家访时收集了有关参与者使用和对空气净化器的反应的数据，使用 HOBO 监测器记录电力消耗，并对参与者进行了结构化访谈。
在过去一个月中，几乎所有 150 名参与者都报告说几乎每天 24 小时都在客厅和卧室里运行空气净化器。来自 45 名参与者的一部分的单元的 HOBO 用电量支持了参与者从问卷中获得的响应。大约 80％的参与者报告将空气净化器设置在中等设置。在 30 天和 90 天的家访中，对空气净化器噪音的容忍度显着增加，大约有三分之二的人完全不受噪音干扰。在 26 名参与者的一小部分中进行的定性访谈得出的结果与问卷中的结果一致。单元的大小、气流和能耗是访谈中出现的其他关注点。
来自问卷、HOBO 数据和结构化访谈的结果均表明参与者对家中存在的空气净化器有积极的反应，因此可能愿意定期在家中使用空气净化器。
