(OP)
Hi guys. I am looking for advice on what type of filter I should be using/looking for. We are testing an inc jet printer by spraying the inc into one end of a sheet metal box. The other end has a strong fan to ensure that all of the inc particles at the print head are captured and pulled into the box. The bottom of the box has a drain. With our current filters, we are having trouble with inc getting through them and the fan is spraying small amounts of ink out the back of the box. I would like to use 2 filters inside the box, approximately 10.5 X 11.5'' but we are willing to cut a larger filter to size if it is easy to do. Any suggestions as to the filter that should be used in this application?

Also, maybe the box idea is not the best way to do this, but perhaps a type of separator (e.g. see the cyclone separator concept)

The idea is to slow the captured air down, to allow the ink particles to fall out of the entrained air and settle to the bottom.
I am presuming that the ink takes several seconds to dry hence the drain in the bottom to accommodate the wet ink.
A commercial paint arrestor should do your job.
