Box Fans do a great job of moving the air. They are very popular in shop areas or garages. The downside is that these areas tend to be more dusty than the inside of homes or offices. And without our Box Fan Air Filters, you are moving the air but also stirring up all the dust and debris in the work area. Our Box Fan Filters solve this problem! Available in both Poly (Economy) or Pleated versions, these Box Fan Air Filters go a long way toward reducing pollutants for the air.
