N95 respirators are ideal for healthcare and industrial workers dealing with extremely contagious diseases such as COVID-19. However, these masks can be uncomfortable and require a tight fit to function properly. These masks filter up to 95% of air particles and are more expensive than conventional masks. <\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-align-center\">KN95 masks<\/h3>\n\n\n\n<p>Both N95 and KN95 are made up of several layers of synthetic material, usually a plastic polymer. The distinction between the two types of masks is their certification.<\/p>\n\n\n\n<p>According to mask manufacturer 3M, &#8220;it is reasonable to consider&#8221; China&#8217;s KN95s &#8220;equivalent&#8221; to US N95s. Mask standards for Europe (FFP2), Australia (P2), Korea (KMOEL), and Japan (DS) are also very similar.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"1048\" height=\"668\" src=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2020\/04\/3M-9320-P2-Mask.jpg\" alt=\"Australia P2 Mask Standards similar to N95 and KN95 masks\" class=\"wp-image-10249\" srcset=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2020\/04\/3M-9320-P2-Mask.jpg 1048w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2020\/04\/3M-9320-P2-Mask-300x191.jpg 300w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2020\/04\/3M-9320-P2-Mask-768x490.jpg 768w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2020\/04\/3M-9320-P2-Mask-1024x653.jpg 1024w\" sizes=\"(max-width: 1048px) 100vw, 1048px\" \/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">Difference Between N95 vs. KN95 Masks<\/h2>\n\n\n\n<p>Both ratings require masks to be tested for filtration efficiency at capturing salt particles (NaCl). Both are tested at a flow rate of 85 L\/minute. However, there are some differences between N95 and KN95, highlighted here.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">KN95 vs. N95 &#8211; Differences Highlighted<\/h4>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/qph.fs.quoracdn.net\/main-qimg-f83412656eab7ee8e8d5986fa07dd23f\" alt=\"Difference Between N95 and KN95 Masks Highlighted\" style=\"width:1000px;height:auto\"\/><\/figure><\/div>\n\n\n<p>Most of these differences are small and would be uninteresting to the average mask user. However, here are the key differences:<\/p>\n\n\n\n<p>1. To be certified as a KN95 mask, the Chinese government requires the manufacturer to run a <a href=\"https:\/\/smartairfilters.com\/en\/blog\/do-pollution-masks-work\/\">special mask fit test on real humans<\/a> with \u2264 8% leakage. The N95 mask standard does not require manufacturers to run fit tests.<\/p>\n\n\n\n<p>This does <strong>not&nbsp;<\/strong>mean that fit tests aren&#8217;t helpful. Many hospitals and companies require their workers to be fit-tested. However, those are requirements of the companies themselves, not for the US <a href=\"https:\/\/en.wikipedia.org\/wiki\/National_Institute_for_Occupational_Safety_and_Health\" target=\"_blank\" rel=\"noopener\">NIOSH<\/a> certification on the mask.<\/p>\n\n\n\n<p>Read more: <a href=\"https:\/\/smartairfilters.com\/en\/blog\/comparison-mask-standards-rating-effectiveness\/\">Comparison of Mask Ratings, Standards, and Filtration Effectiveness (N95, KN95, FFP1, FFP2)<\/a><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/qph.fs.quoracdn.net\/main-qimg-b55397473596b50b26a6d3ad69f758ff.webp\" alt=\"Mask fit test requirements KN95 vs N95\"\/><\/figure><\/div>\n\n\n<p>2. N95 masks have slightly stricter requirements for pressure drop while inhaling. That means they\u2019re required to be slightly more breathable than KN95 masks.<\/p>\n\n\n\n<p>Don&#8217;t worry, despite it sometimes feeling difficult to breathe through masks, <a href=\"https:\/\/smartairfilters.com\/blog\/n95-face-mask-limit-breathe-oxygen\/\">dying from oxygen starvation is very unlikely when wearing a mask<\/a>.<\/p>\n\n\n\n<p>3. N95s also have slightly stricter requirements for pressure drop while <b>exhaling, <\/b>which should help with breathability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">N95 vs. KN95: What&#8217;s the Same?<\/h2>\n\n\n\n<p>Lots of users care most about what percentage of particles the masks capture. On this metric, N95 and KN95 respirator masks are the same. Both masks are rated to capture 95% of tiny particles (0.3 micron particles, to be exact).<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/qph.fs.quoracdn.net\/main-qimg-1026a9a877755055c8dedf36afa57f1e\" alt=\"Differences Between N95 and KN95 Masks standards\"\/><\/figure><\/div>\n\n\n<p>Since N95 and KN95 masks are rated to capture 95% of 0.3-micron particles, people will often assume that masks can&#8217;t capture particles <strong>smaller<\/strong> than 0.3 microns.

In the United States, KN95 masks are far easier to get your hands on than N95 masks. The reason is that KN95 masks do not meet the NIOSH standards for face masks, so hospitals and healthcare facilities can only use N95 masks. For this reason, N95 masks may be reserved for healthcare workers, leaving a larger supply of KN95 masks for the average consumer. This does not mean the KN95 masks are inferior, as long as they are genuine KN95 masks.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">CDC Update (2022): N95\/KN95 Masks and Omicron<\/h4>\n\n\n\n<p>The more contagious COVID-19 omicron variant has put a spotlight on more effective masks such as N95 and KN95 masks. In January of 2022, the CDC updated their <a href=\"https:\/\/www.cdc.gov\/coronavirus\/2019-ncov\/prevent-getting-sick\/types-of-masks.html\">masking guidelines<\/a> stating respirators such as N95 and KN95 &#8220;offer the highest level of protection&#8221;.
