This is what I came up with.

There's a HEPA in the magic blue box. Closed off all other windows that could act as air intake. Turned on the bathroom and kitchen fans. They take air from the inside and exhaust it outside. We're doing ~600 CFM at the intake pipe. The HEPA is tiny in comparison to what a Corsi-Rosenthal box uses but it's compensated by having a high static pressure fan that can pull much more air through it. If it didn't work I was gonna go to CT to get some filters and a fan. :D
