One method of sterilization&nbsp;is&nbsp;by using&nbsp;ozone. Ozone sterilization is commonly&nbsp;<a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0196655304001415\">used in hospitals to sanitize equipment<\/a>&nbsp;and significantly reduce or&nbsp;<a href=\"https:\/\/www.jstor.org\/stable\/26327632?seq=1\">eliminate the spread of bacteria<\/a>. Hence&nbsp;the&nbsp;question being asked&nbsp;is&nbsp;\u2013 \u201cCan ozone sterilization kill the Coronavirus which causes the COVID-19 disease?\u201d&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.aeroqual.com\/wp-content\/uploads\/Steralization-300x199-1.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This\n blog&nbsp;post&nbsp;looks at the evidence and highlights the benefits of \nsterilizing environments with ozone, as well as it\u2019s associated risks.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">OZONE&nbsp;STERILIZATION&nbsp;PROVEN TO KILL SARS-COV VIRUS&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There&nbsp;are&nbsp;currently&nbsp;no examples&nbsp;in the public domain,&nbsp;of ozone&nbsp;sterilization&nbsp;being used to&nbsp;kill&nbsp;the current&nbsp;strain of Coronavirus,&nbsp;SARS-CoV-2\n (technical name of the Coronavirus which causes the COVID-19 disease). \nHowever, there are reasons to believe it would be effective:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>During the SARS epidemic of 2003,&nbsp;<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC3312702\/\">ozone sterilization&nbsp;was successfully used<\/a> to purify environments infected with the deadly Coronavirus, SARS-CoV-1, the virus which causes&nbsp;the SARS disease.&nbsp;<\/li><li>&nbsp;As&nbsp;<a href=\"https:\/\/www.who.int\/ith\/diseases\/sars\/en\/\">SARS-Cov-1<\/a> is also a member of the Coronavirus family, it is highly likely that&nbsp;ozone sterilization would be effective&nbsp;at killing&nbsp;SARS-CoV-2, the Coronavirus which causes the COVID-19 disease.&nbsp;<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">HOW DOES OZONE&nbsp;STERILIZATION KILL&nbsp;CORONAVIRUSES?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Coronaviruses&nbsp;are&nbsp;classified\n as&nbsp;\u201cenveloped viruses\u201d, which \nare&nbsp;typically&nbsp;more&nbsp;susceptible&nbsp;to&nbsp;\u201cPhysico-chemical&nbsp;challenges\u201d.&nbsp;In \nother&nbsp;words,&nbsp;they don\u2019t like&nbsp;being&nbsp;exposed&nbsp;to&nbsp;ozone.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ozone \ndestroys&nbsp;this type of&nbsp;virus by&nbsp;breaking&nbsp;through&nbsp;the \nouter&nbsp;shell&nbsp;into&nbsp;the&nbsp;core, resulting in damage&nbsp;to&nbsp;the&nbsp;viral RNA.&nbsp;Ozone \ncan&nbsp;also&nbsp;damage&nbsp;the outer shell of&nbsp;the virus in a process \ncalled&nbsp;oxidation.&nbsp;Put simply, exposing Coronaviruses to sufficient ozone dose (ppm x time) can result in them being 99% damaged or destroyed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">WHAT ARE THE RISKS&nbsp;OF OZONE STERILIZATION?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Breathing\n even small amounts of ozone can be harmful. Symptoms&nbsp;include&nbsp;coughing, \nshortness of breath, and aggravation of lung diseases like asthma. At \nhigher concentrations you can smell ozone, but it becomes harmful even \nat lower doses. For that&nbsp;reason,&nbsp;many countries have set \nan&nbsp;8-hour&nbsp;exposure limit of&nbsp;70 ppb (parts per billion) ozone. In&nbsp;the \nEU&nbsp;the limit is set even lower. Ozone is one of six common pollutants \nlimited by the&nbsp;<a href=\"https:\/\/www.epa.gov\/\">United States Environmental Protection Agenc<\/a>y&nbsp;and other&nbsp;country\u2019s Environmental regulators. Exposure to ozone in the workplace&nbsp;is controlled by the&nbsp;<a href=\"https:\/\/www.osha.gov\/\">Occupational Safety and Health Administration<\/a>&nbsp;and their counterparts around the world.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">REDUCE THE RISK OF&nbsp;OZONE EXPOSURE&nbsp;BY MONITORING&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Although\n ozone can&nbsp;sterilize&nbsp;coronavirus infected environments,&nbsp;residual&nbsp;ozone \ncould&nbsp;also cause&nbsp;respiratory&nbsp;issues for&nbsp;people who breathe&nbsp;it \nin.&nbsp;To&nbsp;stop this from happening&nbsp;it is important to&nbsp;measure \nand&nbsp;control&nbsp;indoor&nbsp;and outdoor levels of ozone&nbsp;after sterilization has \ntaken place.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The problem is that the equipment for measuring \nozone is either a) accurate but too expensive, or b) affordable but not \naccurate.&nbsp;This is why Aeroqual came up with option c) <a href=\"https:\/\/www.aeroqual.com\/ozone-meters-and-sensors\">monitors that are both accurate and affordable<\/a>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Please <a
