Top Pick20-Inch 3-Speed Box Fan
Rating breakdown
What we love: Engine of the DIY Corsi-Rosenthal purifier — with a MERV 13 filter it rivals commercial units for particle removal. (Provisional smoke-kit rating.)

20x20x1 MERV 13 Filter (MPR 1900)
Rating breakdown
MERV 13, MPR 1900
What we love: Sized to a 20-inch fan face; captures fine smoke particles. Use four in a cube for best results. (Provisional smoke-kit rating.)

Original Duct Tape
Rating breakdown
What we love: Airtight edge seal between filter and fan — edge leaks are what separate mediocre builds from great ones. (Provisional smoke-kit rating.)
