Ideas for Building an Exhaust system

• box with vertically stacked filters (allowing for varialbe height), exhaust goes in at the top, gets filter through HEPA, active carbon, and blown out at the bottom
• radial blower at the bottom (800m3/h, 14m3/min, 470cfm)
• possibly a prefilter that washes easily
• inside padded with foam insulation for noise reduction
• cross section for "20x20 inch filter"
• pressure sensor for detecting full filter
