- CyberDildonics 9y agoI've done that and it does work as a filter in general. The first thing to note is that furnace filters are not HEPA filters. The second thing to note is that HEPA filters don't filter out the same things as activated charcoal (from what I understand).
- mmagin 9y agoBox fans don't work especially well with the backpressure. You'll get vastly less air flow. I think the dust-catching products I've seen like http://www.leevalley.com/us/Wood/page.aspx?p=65482&cat=1,42401&ap=1 http://www.leevalley.com/us/Wood/page.aspx?p=65482&cat=1,424... are a lot less restrictive than a couple furnace filters across the front of the fan.
