I recycled the box and filters from last year, and set up this new hood in a few hours. The box is just a plastic storage bin with some sides cut out, I used 2 different 3M Filtrete air duct filters (I found a good one, then I found a better one so I use both in a series), a normal house fan, trash bags and tape. I mounted it all on a large plastic sheet for convenience if I need to move it, but it is not necessary. The most important part of this style of hood is to make sure that there is a tight seal between the box and the filters and between filters and the front of the fan. If the seal is not good at the fan, then there will not be sufficient force to push the air thru the filters, and if the seal is not tight in the region where the filtered air comes out and enters the hood, then it will pull in unfiltered air with it from the environment and contaminate the hood.
