Should I Be Concerned About a Square Filter on a Round Fan?<\/a> <\/div>\n<p>It\u2019s certainly possible to DIY an air purifier out of free-standing fans. We\u2019ve seen several instances of Smart Air users making DIY air purifiers using them. <\/p>\n\n\n\n<p>Some tips on what to watch out for:<\/p>\n\n\n\n<p>1. Our data shows that having a filter that is able to cover the entire surface of the fan gives the best cleaning efficiency. As such, we recommend you find a HEPA filter big enough for the fan.<\/p>\n\n\n\n<p>2. Free-standing fans typically have an all-metal wire (or plastic) frame, that goes round the entire fan. In this case, it\u2019s very easy for air to pass around the HEPA, instead of going through it. We recommend using tape or cardboard to create a \u2018funnel\u2019 around the fan, so as to push air through the HEPA filter.<\/p>\n\n\n\n<p>Learn more on <a href=\"https:\/\/smartairfilters.com\/en\/blog\/how-to-make-diy-air-purifier\/\">How to Make a DIY Air Purifier \u00bb<\/a><\/p>\n<div class='pauple-helpie-module article-voting'><span class='label'>Was this article useful?<\/span><span data-post-id='5818' data-user-id='0' class='icon-tray'><span  data-vote='thumbs up outline' class=' voting-icon thumbs up outline '><i data-content='thumbs up outline' class='thumbs up outline outline icon' aria-hidden='true'><\/i><count>2<\/count><\/span><span  data-vote='thumbs down outline' class=' voting-icon thumbs down outline '><i data-content='thumbs down outline' class='thumbs down outline outline icon' aria-hidden='true'><\/i><count>0<\/count><\/span><\/span><\/div><div style='clear:both;'><\/div>","protected":false},"excerpt":{"rendered":"<p>Knowledge Base &nbsp;&nbsp; &nbsp;&nbsp;Smart Air Purifiers &nbsp;&nbsp; &nbsp;&nbsp;DIY Air Purifier &nbsp;&nbsp; &nbsp;&nbsp;Can I DIY an Air Purifier Using a Round Standing Fan?
