Is the air coming out of the Smart Air DIY air purifier clean?<\/h3>\n\n\n\n<p>This is the easiest question to answer, and we do it by holding a Dylos DC1100 Pro particle counter in front of the purifier and watching the numbers drop. Here&#8217;s a video of Thomas doing just that:<\/p>\n\n\n<div class=\"gb-container gb-container-f5dfa52d\"><div class=\"gb-inside-container\">\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"lyte-wrapper\" title=\"Smart Air Original DIY Air Purifier Live Test with Dylos Particle Counter (CN Subtitles)\" style=\"width:640px;max-width:100%;margin:5px auto;\"><div class=\"lyMe hidef\" id=\"WYL_JpfpZofUzNo\" itemprop=\"video\" itemscope itemtype=\"https:\/\/schema.org\/VideoObject\"><div><meta itemprop=\"thumbnailUrl\" content=\"https:\/\/i.ytimg.com\/vi\/JpfpZofUzNo\/maxresdefault.jpg\" \/><meta itemprop=\"embedURL\" content=\"https:\/\/www.youtube.com\/embed\/JpfpZofUzNo\" \/><meta itemprop=\"duration\" content=\"PT2M3S\" \/><meta itemprop=\"uploadDate\" content=\"2015-07-24T14:48:52Z\" \/><\/div><meta itemprop=\"accessibilityFeature\" content=\"captions\" \/><div id=\"lyte_JpfpZofUzNo\" data-src=\"https:\/\/i.ytimg.com\/vi\/JpfpZofUzNo\/maxresdefault.jpg\" class=\"pL\"><div class=\"tC\"><div class=\"tT\" itemprop=\"name\">Smart Air Original DIY Air Purifier Live Test with Dylos Particle Counter (CN Subtitles)<\/div><\/div><div class=\"play\"><\/div><div class=\"ctrl\"><div class=\"Lctrl\"><\/div><div class=\"Rctrl\"><\/div><\/div><\/div><noscript><a href=\"https:\/\/youtu.be\/JpfpZofUzNo\" rel=\"nofollow\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.ytimg.com\/vi\/JpfpZofUzNo\/0.jpg\" alt=\"Smart Air Original DIY Air Purifier Live Test with Dylos Particle Counter (CN Subtitles)\" width=\"640\" height=\"340\" \/><br \/>Watch this video on YouTube<\/a><\/noscript><meta itemprop=\"description\" content=\"Live test of Smart Air Original DIY Air Purifer by Thomas Talhelm.

Is the Smart Air DIY air purifier able to actually clean the air in the entire room?<\/h3>\n\n\n\n<p>Answering this question is more difficult because you need a controlled environment (for example, you don\u2019t want to walk in and out of the room during the test), and you need to test the air for a longer period of time. But fortunately for you, Thomas is a huge nerd and does this kind of thing for fun.<\/p>\n\n\n\n<p>To answer this, Thomas set up the <a href=\"http:\/\/particlecounting.tumblr.com\/post\/55427024364\/the-beast-the-dylos-dc1100-pro-air-quality\">particle counter<\/a> on one side of his 13.5 m<sup>2<\/sup> bedroom and put the DIY filter on the opposite side of the room. Here&#8217;s what our filter did in one hour:<\/p>\n\n\n\n<div style=\"text-align:center\"><img decoding=\"async\" src=\"\/wordpress\/wp-content\/uploads\/sites\/3\/2021\/03\/filter-test-particle-concentration-pm25-minutes.jpg\" width=\"100%\" style=\"max-width:600px\"><\/div>\n\n\n\n<p>And over the course of eight hours:<\/p>\n\n\n\n<div style=\"text-align:center\"><img decoding=\"async\" src=\"\/wordpress\/wp-content\/uploads\/sites\/3\/2021\/03\/filter-test-particle-concentration-pm25-hours.png\" width=\"100%\" style=\"max-width: 600px\"><\/div>\n\n\n\n<p>The particle counter also gives data on .5 micron particles \u2014 even smaller than the 2.5 micron reading. Here&#8217;s what that looks like over eight hours:<\/p>\n\n\n\n<div style=\"text-align:center\"><img decoding=\"async\" src=\"\/wordpress\/wp-content\/uploads\/sites\/3\/2021\/03\/filter-test-particle-concentration-pm5-hours.jpg\" width=\"100%\" style=\"max-width:600px\"><\/div>\n\n\n\n<h5 class=\"gb-headline gb-headline-4c2c19d3 gb-headline-text\"><strong>Conclusion:<\/strong> Yes, the clean air from the DIY filter is cleaning the entire room.<\/h5>\n\n\n\n<p class=\"gb-headline gb-headline-f043cfa8 gb-headline-text\"><a href=\"https:\/\/smartairfilters.com\/blog\/supplemental-data-testing-methodology-for-diy-purifier\/#method2\">Want to know more about our methodology?

Thomas calculated effectiveness as percent reduction in particulates from the room air. Anna tested the air before she turned on the air filter, and then set the particle counter to take hourly measurements of the air in her 15m<sup>2<\/sup> Beijing bedroom. Anna used the highest setting on each filter.<\/p>\n\n\n\n<div style=\"text-align:center\"><img decoding=\"async\" src=\"\/wordpress\/wp-content\/uploads\/sites\/3\/2021\/03\/diy-average-effectiveness-particulates-removed-graph.jpg\" width=\"100%\" style=\"max-width:700px\"><\/div>\n\n\n\n<p>All of the filters significantly reduced particulates, but the <a href=\"http:\/\/item.taobao.com\/item.htm?spm=a1z10.1.w4004-7525708604.2.KkyOmq&amp;id=36350325474\">470 RMB<\/a> <a href=\"\/cn\/en\/#compare\">Cannon<\/a> removed as many particles as the highest-performing big brand.
