One common complaint I notice is constant dust in the vehicle. Wondering if anyone has built and tried this clever device. Video here If you're leery of clicking a live link, search youtube for Quality DIY Box Fan Air Purifier the "Comparetto Cube". Originally saw it on recent Ask this Old House episode. Affordable, easy to put together, and highly effective. No mention of it on this forum. I'll be building one. Combined with a 12 volt air compressor to blow cabinets and surfaces (of course wearing an N95 mask), believe it could keep dust way down
