So radon is also a solid.<\/p>\n\n\n\n<h4 class=\"has-text-align-center wp-block-heading\">Is Radon Dangerous?<\/h4>\n\n\n\n<p>Those particles can then get&nbsp;<a href=\"https:\/\/www.cdc.gov\/nceh\/features\/protect-home-radon\/index.html\" target=\"_blank\" rel=\"noreferrer noopener\">stuck in our lungs<\/a>&nbsp;when we breathe. Exposure to radon particles makes people&nbsp;<a href=\"https:\/\/www.who.int\/news-room\/fact-sheets\/detail\/radon-and-health\" target=\"_blank\" rel=\"noreferrer noopener\">more likely to get cancer<\/a>.<\/p>\n\n\n\n<h4 class=\"has-text-align-center wp-block-heading\">Where Does Radon Come From?<\/h4>\n\n\n\n<p>Radon often comes from radioactive uranium that is&nbsp;<a href=\"https:\/\/www.who.int\/news-room\/fact-sheets\/detail\/radon-and-health\" target=\"_blank\" rel=\"noreferrer noopener\">naturally in some rocks and soil<\/a>. Sometimes radon is&nbsp;<a href=\"https:\/\/www.who.int\/news-room\/fact-sheets\/detail\/radon-and-health\" target=\"_blank\" rel=\"noreferrer noopener\">in water<\/a>&nbsp;too.<\/p>\n\n\n\n<p>The ground in some areas has more radon than in other areas. For example, in the US, the Appalachian Mountain region&nbsp;<a href=\"https:\/\/www.indoor-air-health-advisor.com\/radon-map.html\" target=\"_blank\" rel=\"noreferrer noopener\">has high radon levels<\/a>, but the lowland south has low levels.<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"450\" height=\"320\" src=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonUSA.jpg\" alt=\"Radon levels in the US\" class=\"wp-image-26128\" srcset=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonUSA.jpg 450w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonUSA-300x213.jpg 300w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/figure><\/div>\n\n\n<p>Outdoors, radon is&nbsp;<a href=\"https:\/\/www.who.int\/news-room\/fact-sheets\/detail\/radon-and-health\" target=\"_blank\" rel=\"noreferrer noopener\">usually not a problem<\/a>. That\u2019s because there\u2019s so much air that the amount of radon is very small. So if you\u2019re hiking in the Appalachian Mountains, don\u2019t worry.<\/p>\n\n\n\n<p>But indoors, it can accumulate. In some buildings, it\u2019s particularly problematic in the ground floor or basement floor, because radon can come up from the ground.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"602\" height=\"386\" src=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonEnteringHome.jpg\" alt=\"Radon entering the home\" class=\"wp-image-26129\" srcset=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonEnteringHome.jpg 602w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonEnteringHome-600x385.jpg 600w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonEnteringHome-300x192.jpg 300w\" sizes=\"(max-width: 602px) 100vw, 602px\" \/><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<h2 class=\"has-text-align-center wp-block-heading\">Can HEPA Filters Capture Radon?<\/h2>\n\n\n\n<p>Radon emerges from the ground as a gas, and HEPA filters&nbsp;<a href=\"https:\/\/ehs.umass.edu\/air-purifiers-fact-sheet\" target=\"_blank\" rel=\"noreferrer noopener\">do not capture gases<\/a>. So that\u2019s bad news.<\/p>\n\n\n\n<p>But after radon decays into particles, HEPA filters can be useful. The <a href=\"https:\/\/smartairfilters.com\/en\/blog\/how-big-are-radon-particles\">size of radon particles<\/a> ranges from .5-300 nanometers. <\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"602\" height=\"340\" src=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonParticleSize.jpg\" alt=\"Radon particle sizes\" class=\"wp-image-26131\" srcset=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonParticleSize.jpg 602w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonParticleSize-600x339.jpg 600w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2023\/03\/RadonParticleSize-300x169.jpg 300w\" sizes=\"(max-width: 602px) 100vw, 602px\" \/><\/figure><\/div>\n\n\n<p>Fortunately, HEPA filters can&nbsp;<a href=\"https:\/\/smartairfilters.com\/en\/blog\/can-hepa-filters-capture-nanoparticles\/\" target=\"_blank\" rel=\"noreferrer noopener\">remove over 99% of particles in the nanometer range<\/a>.
