You can also make smaller versions and hang them high in corners of a room, where the smoke tends to concentrate.
Things You Will Need
-
Lay your box fan on the floor with the back of the machine facing you. Position a furnace filter over the back of it. Line up at least two sides carefully. Seal these to the unit with duct tape.
-
Tape the filter snugly to the back of the fan. Don't worry if some excess filter sticks out a bit. Plug in the unit -- turn it on -- and you are filtering your air already. The higher the output setting is, the more air filtration you will be able to generate.
-
Replace the filter when it starts to show signs of discoloration, or when it collects too much soot or dust.
-
Find smaller filters, or use scissors to cut up large ones, to attach to the back of your smaller fans. If you can mount a few smaller fans in the high corners of a small room, while your box fan is set up in the central area, this will maximize the filtration of the whole room.
