Search online and you can find lots of them that move 200 cubic feet per minute (cfm) for $100 to $150. But, if you put one in a semi-attractive (emphasis on the &#8220;semi&#8221;) package, create some fancy marketing materials, and target people who don&#8217;t know much building science, you can charge $1,200 to $1,700 for that same fan. At least that seems to be the business plan for these three companies.<\/p>\n<p><a href=\"http:\/\/www.greenbuildingadvisor.com\/blogs\/dept\/building-science\/beware-expensive-ventilation-scam\" target=\"_blank\">read more<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[12719,12720,9392,12721,12722,12723,6258,6137],"class_list":["post-28389","post","type-post","status-publish","format-standard","hentry","category-green-building-posts","tag-basement","tag-basement-ventilation","tag-crawl-space","tag-crawl-space-ventilation","tag-damp-basement","tag-damp-crawl-space","tag-humidity","tag-ventilation"],"_links":{"self":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts\/28389","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/comments?post=28389"}],"version-history":[{"count":0,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/posts\/28389\/revisions"}],"wp:attachment":[{"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/media?parent=28389"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/categories?post=28389"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/leedpoints.com\/green-building-blog\/wp-json\/wp\/v2\/tags?post=28389"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
