These emit ozone, which can alter the air chemistry in a room resulting in secondary pollutants<\/li>\n\n\n\n<li>Air purifiers tend to be sold on the basis of the clean air it produces on top speed - which is usually too noisy. Turning it down means you are no longer cleaning the air at the same rate you were promised<\/li>\n<\/ul>\n\n\n\n<p>Ensuring a safe and healthy environment for students and staff should be your priority. With a variety of options in the market, it's so important to pick an air purifier that ticks all the boxes without breaking the bank.&nbsp;<\/p>\n\n\n\n<p>We were delighted to learn that a UK county council installed air purifiers in more than 30 primary schools and that there are plans to roll out to even more schools. While we are really fond of our own products, we are staunch advocates of good indoor air quality so we celebrate all successes, especially when it comes to schools.<\/p>\n\n\n\n<p>We hope that this investment in filtration will be replicated by other county councils so we have taken the opportunity to review their selected air purifiers to see how well it performs in classrooms.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:55%\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXebdfHgnxqoNx9LeC5NEZTbfcabxzw_IatVgDWK74csQn1iQRsywVgRgid332WbnbZTmiSwYeM3gVsA86kJBTvcpVqWDu8SXT3bQy4qWxSHSsgj0ZABNlrxF-fjsCFLjmX9pSBt0kLdZGeX-5hjstWd_rU?key=NjS39WjY_OOhOHTs_54AsA\" alt=\"\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:45%\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXd1gAuTqecE07dvQgtDue1gv3BjNbhgbK1Myupk1eqJa3m3-nM2OeYtV3cECzOfF9KBcJ1AGah99wOKpFxGC6JWl-ztcI1AJ1V-L22I-1cLCcwlmDoR8_5mAjMAKewMYfP0L0Wp1IluWktridExty7XwBY?key=NjS39WjY_OOhOHTs_54AsA\" alt=\"\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p>The first thing that hits us is the price, more on this later, but the great news is that it delivers a powerful 800m\u00b3\/hr of clean air.

However, the M8&nbsp; includes additional features like the UV\u2013C light (<span style=\"text-decoration: underline\"><a href=\"https:\/\/max-vac.com\/en-gb\/products\/medi-8-uvc-hepa-air-purifier\" target=\"_blank\" rel=\"noreferrer noopener\">upfront marketing<\/a><\/span>) and ionisers (found in <a href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0550\/8674\/3596\/files\/MAXVAC_Medi_8_Manual_1.3.pdf?\" target=\"_blank\" rel=\"noreferrer noopener\"><span style=\"text-decoration: underline\">documentation<\/span><\/a>), which can raise concerns. <\/p>\n\n\n\n<p>As far as we are aware, there are no peer-reviewed independent studies on the effectiveness of these products <em>inside<\/em> air purifiers. Yet we know that both can produce ozone. HEPA filters will do all of the work and if anyone is selling the added potential benefit of \u2018killing viruses\u2019 on filters where they can't survive for long anyway, we recommend you ask to see the independent research report that's been peer-reviewed.<\/p>\n\n\n\n<p>In the US, the Environmental Protection Agency (EPA) recommends against purchasing air purifiers that emit ozone, which includes those that contain <a href=\"https:\/\/smartairfilters.com\/en\/blog\/uv-light-air-purifiers-uvgi-far-uv-covid-virus\/\"><span style=\"text-decoration: underline\">UV lights<\/span><\/a>. We couldn\u2019t agree more. Smart Air believes in no nonsense air filtration system, our air purifiers are Simply HEPA with no ozone.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Price should not be the main factor<\/h4>\n\n\n\n<p>Choosing an air purifier should be based on the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Air changes per hour (ACH)<\/li>\n\n\n\n<li>Noise<\/li>\n\n\n\n<li>Price - upfront and ongoing costs (running and filter replacement)<\/li>\n\n\n\n<li>Energy usage<\/li>\n<\/ul>\n\n\n\n<p>We believe we need to shift the focus away from <a href=\"https:\/\/smartairfilters.com\/uk\/en\/blog\/ach-vs-cadr\/\"><span style=\"text-decoration: underline\">Clean Air Delivery Rate (CADR) to ACH and Noise<\/span><\/a> so it is clearer for schools to see what they are getting. We see a range of school purchases from low-cost domestic purifiers to expensive bells and whistle commercial devices. Be aware that unless you factor in the right amount of clean air for your size space, at the noise levels you can teach at, any money you pay could be money down the drain.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">The distance from the wall is sometimes only found in user manuals<\/h4>\n\n\n\n<p>Another significant drawback for classrooms is space and we have found that the M8 requires a <strong>1-metre clearance<\/strong> around the device for optimal air circulation. This means to get the top level CADR, the device must be at least 1m away from the wall, which is particularly challenging in crowded classrooms, where space is often limited. For comparison, the Blast must be sited 15cm away from the wall for optimal air circulation.<\/p>\n\n\n\n<p>The M8 is a high-end air purifier which delivers exceptional performance but unfortunately not at noise levels conducive to continuous teaching. If you have this unit in your classroom, we recommend switching off auto mode daily and asking your supplier what the CADR levels are on speeds 2 and 3, which we were unable to find.<\/p>\n\n\n\n<p>For \u00a3999 exclusive of VAT, you can actually purchase 2x Blasts or 5x SA600s for the same price, bringing clean air to more classrooms across the school.<\/p>\n\n\n<div class='bottom-line'><div class='bottom-line-top'>Bottom Line<\/div><div class='bottom-line-title'>Simply placing a HEPA filter in your class may not be enough<\/div><div class='bottom-line-content'><\/p>\n<p>When choosing an air purifier for schools, noise and CADR correctly sized for your room should be your primary considerations.
