进行了全面的定量实验，以评估几种空气净化装置为过敏性鼻炎和哮喘患者创造无颗粒微环境的能力。评估了六个设备，其中五个是便携式的，旨在为卧室大小的空间提供一般空气净化。第六个是安装在床的床头板前，旨在为睡觉的人提供清洁的空气。所选设备的空气净化方式包括高效微粒空气（HEPA）过滤和静电沉淀。在8小时模拟睡眠期间测量6个粒径范围的颗粒浓度和声强。研究了四个参数的影响：(i)装置位置，（ii）控制实验室空气运动，（ii）空气净化装置的气流速率设置，以及（iv）控制扰动。为了确保完全客观的研究，建立了一个特殊的实验室设施，可以完全控制实验条件。测量的浓度历史提供了各种设备的特定空气净化功能的相对能力的综合证据。研究发现，该装置旨在将净化后的空气集中在睡眠空间，达到了目的，在这方面，它明显优于所有其他空气净化装置。
Comprehensive quantitative experiments were performed to assess the capabilities of several air-cleaning devices to create a particle-free microenvironment as a therapy for sleeping persons affected by allergic rhinitis and asthma. Six devices were evaluated, of which five were portable and intended to provide general air cleaning for bedroom-sized spaces. The sixth was intended for installation in front of the headboard of a bed and was designed to provide clean air focused in a space occupied by a sleeping person. The air-cleaning methods of the selected devices included high-efficiency particulate air (HEPA) filtering and electrostatic precipitation. Particle concentration measurements for six particle-size ranges and sound intensity measurements were made during 8-h, sleep-simulating periods. The effects of four parameters were studied: (i) device location, (ii) controlled air motion in the laboratory, (ii) airflow rate setting of the air-cleaning device, and (iv) controlled disturbances. To ensure a totally objective study, a special laboratory facility was constructed which enabled complete control of the experimental conditions. The measured concentration histories provided comprehensive evidence of the relative capabilities of the various devices for the specific air-cleaning function. It was found that the device designed to focus the cleaned air in the sleeping space fulfilled its goal and, in that regard, was clearly superior to all of the other air-cleaning devices.
