It&#8217;s clear: using an air purifier reduced the impacts of air pollution on people&#8217;s health.<\/p>\n<p>This hits on an important fact I discovered. Air pollution doesn\u2019t kill like we think it does. When the World Health Organization tallied up air pollution deaths per year, they found that lung cancer only\u00a0<a href=\"http:\/\/www.who.int\/en\/news-room\/fact-sheets\/detail\/ambient-(outdoor)-air-quality-and-health\">accounted for 14%<\/a>. Other lung problems like bronchitis were another 14%. So what\u2019s the other 72%\u2014the large majority of air pollution deaths? Heart attacks and strokes.

Build your own or buy a low-cost, data-backed purifier. When I started searching for air purifiers, I saw lots of people buying $500 Blue Air\u2019s and $2,000 IQ Air\u2019s. I wondered, does clean air need to be so expensive? Is there any truth to their claims about special technology or imported HEPA filters?<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/wordpress\/wp-content\/uploads\/2018\/09\/13.jpg\" alt=\"Air purifiers can be cheap\" width=\"500\" height=\"687\" class=\"aligncenter wp-image-6647\" \/><\/p>\n<p>After researching air purifiers, I found out the main ingredient in purifiers \u2014 HEPA filters \u2014 were invented back in the 1940s.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/wordpress\/wp-content\/uploads\/2018\/09\/14.jpg\" alt=\"HEPA filters invented in 1940s - cheap technology\" width=\"575\" height=\"406\" class=\"aligncenter wp-image-6648\" \/><\/p>\n<p><\/p>\n<p>Fans aren\u2019t expensive either.

Or they do capture small particles, but unless they\u2019re professionally fitted, the pollution leaks in, so they\u2019re basically useless. Even <a href=\"https:\/\/smartairfilters.com\/en\/blog\/npr-got-masks-facts-wrong\/\">news media outlets<\/a> say that masks don&#8217;t work well.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"\/wordpress\/wp-content\/uploads\/2018\/09\/mask.png\" alt=\"mask use in London, UK to protect from PM2.5 air pollution\" width=\"591\" height=\"245\" class=\"aligncenter wp-image-6663 \" \/><\/p>\n<p>Before I saw the research on masks, I would have guessed they kinda work all right.
