Fortunately I was able to finally get my hands on some Kodak Aerochrome III as an early Christmas present for myself. I've been researching a lot online but couldn't find the particular filter used by Richard Mosse for his Infra project. The internet suggest using yellow, orange, and red filters for the best results. However, apparently Kodak recommends a yellow filter (https://www.kodak.com/uploadedFiles/Corporate/Industrial_Materials_Group/ti2562.pdf).
I've found that an orange 16 filter seems to work the best, at least for me. I rate it at EI 500, as I've found this keeps the highlights and bright areas from blowing-out too much. You'll definitely want to experiment some, though.
