What Our Lab Data Reveals"},"content":{"rendered":"\n<p>On the morning of June 7, 2023, I walked out of my Brooklyn apartment and noticed the skies were hazier than usual, but I chalked it up to a change in weather and headed to work. When I arrived at my Manhattan office that overlooked the Hudson River, though, I knew this was something very different.&nbsp;<\/p>\n\n\n\n<p>On a normal day, I\u2019d have a clear view of New Jersey on the other side of the water, but on this day, it was merely a blur. As I inspected the thick fog, it dawned on me: This wasn\u2019t fog at all. It was smoke from wildfires that were raging in Canada. The <a href=\"https:\/\/www.cnet.com\/home\/smart-home\/this-do-it-all-air-quality-monitor-is-keeping-my-home-fresh\/\" target=\"_blank\" rel=\"noreferrer noopener\">air quality monitor<\/a> on my phone\u2019s weather app confirmed it.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image alignright size-large\"><a href=\"https:\/\/www.cnet.com\/labs\/\" target=\"_blank\" rel=\" noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"406\" height=\"327\" src=\"https:\/\/www.cnet.com\/wp-content\/uploads\/sites\/2\/017c408d-642d-4aaa-88be-5262ad57f05c.png?w=406\" alt=\"\" class=\"wp-image-4764862\" srcset=\"https:\/\/www.cnet.com\/wp-content\/uploads\/sites\/2\/017c408d-642d-4aaa-88be-5262ad57f05c.png 406w, https:\/\/www.cnet.com\/wp-content\/uploads\/sites\/2\/017c408d-642d-4aaa-88be-5262ad57f05c.png?resize=300,242 300w\" sizes=\"auto, (max-width: 406px) 100vw, 406px\" \/><\/a><\/figure>\n\n\n\n<p>Although there was a thick plume of smoke over the city, I could still see the blue skies peeking through, so I continued to work. But by the end of the day, the sky had turned completely dark with an ominous orange tint. This experience was a first for me, so I was alarmed about having to go back outside to return home, and I wasn\u2019t alone, as people in my office began passing out dust masks. I wasn\u2019t sure if they\u2019d help much, but I took one just in case.&nbsp;<\/p>\n\n\n<div class=\"wp-block-ziff-davis-exco-video\"\n\tid=\"exco-video-block-973ce3fa-6b3f-5a35-ba41-a3d7f0a2667f-4939219-1\"\n\tdata-exco-video-id=\"973ce3fa-6b3f-5a35-ba41-a3d7f0a2667f\"\n\tdata-exco-playlist-id=\"\"\n\tdata-exco-video-title=\"How We Test Air Purifiers with Smoke Bombs\"\n\tdata-exco-video-src=\"https:\/\/cdn.ex.co\/transformations-account\/production\/bf6379df-047b-4e0a-b804-89ce1cc89281\/973ce3fa-6b3f-5a35-ba41-a3d7f0a2667f\/master.m3u8\"\n\tdata-exco-video-duration=\"83\"\n\tdata-exco-video-poster=\"https:\/\/cdn.ex.co\/video-uploads\/production\/0010J00001l1J64QAE\/973ce3fa-6b3f-5a35-ba41-a3d7f0a2667f-thumbnail.jpeg?cb=1790804340279\"\n\tdata-exco-suppress-ads=\"0\"\n\tdata-exco-autoplay=\"0\"\n\tdata-exco-sticky=\"1\">\n\t\t<div class=\"exco-video-player\" id=\"exco-player-973ce3fa-6b3f-5a35-ba41-a3d7f0a2667f-4939219-1\">\n\t\t\t\t\t<img class=\"exco-video-player__poster\"\n\t\t\t\tsrc=\"https:\/\/cdn.ex.co\/video-uploads\/production\/0010J00001l1J64QAE\/973ce3fa-6b3f-5a35-ba41-a3d7f0a2667f-thumbnail.jpeg?cb=1790804340279\"\n\t\t\t\talt=\"How We Test Air Purifiers with Smoke Bombs\"\n\t\t\t\tloading=\"lazy\" \/>\n\t\t\t<\/div>\n<\/div>\n\n\n\n<p>Even in the subway system, the smell of smoke was undeniable.

Texas and the West Coast are particularly vulnerable to these recurring disasters due to their dry climates and the intensifying effects of climate change.

Louisville, Kentucky, our technicians built a custom smoke chamber to test how quickly an air purifier can remove particulate matter from the air. They created a homemade smoke bomb made from potassium nitrate (KNO3), sucrose (sugar) and sodium bicarbonate (baking soda), then placed it in the smoke chamber along with the unit being tested and a particle counter.&nbsp;<\/p>\n\n\n\n<p>This test showcases how well each air purifier works at clearing both coarse and fine particles. When determining which unit is best for wildfire smoke, we paid close attention to the fine-particle result, since, according to <a href=\"https:\/\/www.airnow.gov\/sites\/default\/files\/2021-05\/wildfire-smoke-guide-revised-2019-chapters-1-3.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">AirNow<\/a>, &#8220;approximately 90% of total particle mass emitted from wildfires consists of fine particles.&#8221;<\/p>\n\n\n\n<p>Fine particles are also the most detrimental to human health because they are tiny, <a href=\"https:\/\/www.epa.gov\/wildfire-smoke-course\/wildfire-smoke-complex-mixture\" target=\"_blank\" rel=\"noreferrer noopener\">less than or equal to 2.5 microns<\/a>, so when they are inhaled, they can embed deep into your lungs and cause numerous health issues.&nbsp;<\/p>\n\n\n\n<p>Our lab data revealed that two Coway air purifiers and one Dreame air purifier especially excelled at clearing fine particles.<\/p>\n\n\n\n<p>The <a data-aps-asc-subtag=\"4939219|2\" data-aps-asc-tag=\"cnet-buy-button-20\" data-aps-asin=\"B01C9RIAFS\" data-wp-interactive=\"zd\/analytics\" data-wp-on--click=\"actions.trackClick\" data-zd-otc=\"1\" data-zd-track-action-outcome=\"outbound_click\" data-zd-track-event=\"select_item,view_item\" data-zd-track-item-category=\"MANUAL-OFFER-NO-PRODUCT-CATALOG-ENTRY\" data-zd-track-item-list-index=\"null\" data-zd-track-item-name=\"https:\/\/www.amazon.com\/dp\/B01C9RIAFS\" data-zd-track-location-id=\"BODY\" data-zd-track-module=\"LINK\" data-zd-track-monetization-intent=\"opted_in\" data-zd-track-monetization-status=\"on\" data-zd-track-outbound-url=\"https:\/\/cc.cnet.com\/v1\/otc\/04Yxjj1rHOmYAxbnVDhvKNn?merchant=05kie42h3YvHwjr4G1w80Qq&amp;url=https%3A%2F%2Fwww.amazon.com%2Fdp%2FB01C9RIAFS&amp;app_deeplink=1&amp;u=https%3A%2F%2Fwww.cnet.com%2Fhome%2Fkitchen-and-household%2Fair-purifiers-wildfire-smoke-lab-data%2F\" data-zd-track-page-uuid=\"4939219|2\" data-zd-track-raw-outbound-url=\"https:\/\/cc.cnet.com\/v1\/otc\/04Yxjj1rHOmYAxbnVDhvKNn?merchant=05kie42h3YvHwjr4G1w80Qq&amp;url=https%3A%2F%2Fwww.amazon.com%2Fdp%2FB01C9RIAFS&amp;app_deeplink=1&amp;u=https%3A%2F%2Fwww.cnet.com%2Fhome%2Fkitchen-and-household%2Fair-purifiers-wildfire-smoke-lab-data%2F\" data-zd-track-raw-url=\"https:\/\/www.amazon.com\/dp\/B01C9RIAFS\" href=\"https:\/\/cc.cnet.com\/v1\/otc\/04Yxjj1rHOmYAxbnVDhvKNn?merchant=05kie42h3YvHwjr4G1w80Qq&#038;url=https%3A%2F%2Fwww.amazon.com%2Fdp%2FB01C9RIAFS&#038;app_deeplink=1&#038;u=https%3A%2F%2Fwww.cnet.com%2Fhome%2Fkitchen-and-household%2Fair-purifiers-wildfire-smoke-lab-data%2F\" target=\"_blank\" rel=\"noopener nofollow sponsored\" data-product-uuid=\"9f041878-7ccd-4f6d-ad6a-9359bd1db2a2\" data-zd-track-element-label=\"Coway 400S\">Coway 400S<\/a> is our top pick for clearing smoke from your home because of its exceptional performance at high fan speed.
