Although outdoor individual protection could be achieved by facial masks, indoor air usually relies on expensive and energy-intensive air-filtering devices. Here, we introduce a transparent air filter for indoor air protection through windows that uses natural passive ventilation to effectively protect the indoor air quality. By controlling the surface chemistry to enable strong PM adhesion and also the microstructure of the air filters to increase the capture possibilities, we achieve transparent, high air flow and highly effective air filters of ~90% transparency with &gt;95.00% removal of PM<sub>2.5<\/sub>\u00a0under extreme hazardous air-quality conditions (PM<sub>2.5<\/sub>\u00a0mass concentration &gt;250\u2009\u03bcg\u2009m<sup>\u22123<\/sup>). A field test in Beijing shows that the polyacrylonitrile transparent air filter has the best PM<sub>2.5<\/sub>\u00a0removal efficiency of 98.69% at high transmittance of ~77% during haze occurrence.<\/p>\n<h3 class=\"h3 strong small-space-below\">Publication history<\/h3>\n<div class=\"grid grid-12\">\n<div class=\"grid grid-3 mq875-grid-12 sans-serif text14\">\n<h4>Received<\/h4>\n<p class=\"standard-space-below\"><time datetime=\"2014-09-01\">01 September 2014<\/time><\/p>\n<\/div>\n<div class=\"grid grid-3 mq875-grid-12 sans-serif text14\">\n<h4>Accepted<\/h4>\n<p class=\"standard-space-below\"><time datetime=\"2015-01-06\">06 January 2015<\/time><\/p>\n<\/div>\n<div class=\"grid grid-3 mq875-grid-12 sans-serif text14 last\">\n<h4>Published<\/h4>\n<p class=\"standard-space-below\"><time datetime=\"2015-02-16\">16 February 2015<\/time><\/p>\n<\/div>\n<\/div>\n<h3 class=\"h3 strong mb4\"><abbr title=\"Digital Object Identifier\">DOI<\/abbr><\/h3>\n<p class=\"standard-space-below text14\"><a href=\"https:\/\/doi.org\/10.1038\/ncomms7205\">https:\/\/doi.org\/10.1038\/ncomms7205<\/a><\/p>\n<\/div>\n<\/blockquote>\n<p>Source: <em><a href=\"https:\/\/www.nature.com\/articles\/ncomms7205\">Transparent air filter for high-efficiency PM2.5 capture | Nature Communications<\/a><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Kh\u00f4ng ng\u1ea1c nhi\u00ean khi ti\u1ebfn b\u1ed9 trong vi\u1ec7c nghi\u00ean c\u1ee9u b\u1ed9 l\u1ecdc kh\u00f4ng kh\u00ed \u0111\u1ebfn t\u1eeb Trung Qu\u1ed1c.
