The authors initiated random placement of a working PM<sub>2.5<\/sub> filtration device and a placebo filtration device within the children&#8217;s bedrooms for two weeks, incorporating a two-week washout interval period.<\/p>\n<p>The researchers found that while using the PM<sub>2.5<\/sub> filtration device, the concentrations of PM<sub>2.5<\/sub> within the bedrooms were a mean (SD) of 63.4 percent (35.9 percent) lower than when the placebo filter was used. The use of a true filter also incrementally improved airway mechanics, shown in peak expiratory flow (1.6 percent) and fractional exhaled nitric oxide (a 27.6 percent reduction). Additionally, the children exhibited a reduction in total airway resistance of 24.4 percent, a reduction of 43.5 percent in small airway resistance, a reduction of 22.2 percent in resonant frequency, and an increase of 73.1 percent in airway reactance.<\/p>\n<p>&#8220;These observations support a future clinical trial to assess the efficacy and effectiveness of indoor air filtration in improving small airway pathophysiology that plays a vital role in asthma,&#8221; the authors write.<\/p>\n<p><a href=\"https:\/\/jamanetwork.com\/journals\/jamapediatrics\/article-abstract\/2763826\" target=\"_new\" rel=\"noopener noreferrer\">Abstract\/Full Text (subscription or payments may be required)<\/a><\/p>\n<p><i><\/i><\/p>\n<p><i>Copyright \u00a9 2020 <a href=\"https:\/\/www.healthday.com\/\" target=\"_new\" rel=\"noopener noreferrer\">HealthDay<\/a>.
