Lopho's Mini-Culligan Fan Tek
I bought a Honeywell 16200 HEPA for $40 from home depot along with Great Stuff spray foam insulation sealant. I went to a specialty vacuum cleaner shop and bought the small plastic attachments used for super cheap. With those parts combined I built a "culligan fan" (see also: FM's Homer Tek and the redesign)

This fan is now the backbone of my Homer Bin setup and can provided positive pressure for my glovebox also by switching which tubes are connected to the output holes. I attached a 1 1/2in. PVC sink extension to the side of a clear rubbermaid w/ armholes for the glovebox.
The vacuum attachments must have a slightly wider diameter than the tubing and using a cut half latex glove and rubber bands will create an airtight seal.

When constructing the culligan fan I had to remove most of the plastic grating that covers the clean air output holes first to hookup. A Dremmel would have been perfect for the job, but I'm cheap so I used an old soldering iron (damn plastic fumes wear a mask if you resort to melting plastic like me). After that I sanded down the main plastic surfaces I intended to apply the sealant to and cleaned out all the dust from sanding, wiped the inside surfaces of the unit with rubbing alcohol to re-sanitize, and ran the unit for a length of time. I put on some gloves because Good Stuff expands and can be very messy if you do not work quickly and sealed on the vacuum nozzles.

edit: oh ya those are lysol wipes stuffed in the nozzles to take the pic

How is he going to maintain humidity with that thing running? I assume it will be on a timer, but geez, that's a lot of air to move in a bin. It might just stir up things better left settled.

he mentions using it in his 'homer' set up,
which means multiple large chambers run off the one unit, humidity supplied by another device.
i copied it more for its' application for a glovebox.
