If your looking for the 7" dia. I have 8 of the 100 micron nylon I don't need. I had to stick with the poly filters because I think i have to much flow for the nylon.
I bought them from a wholesale filter supplier here in Calgary but I'll have to try and dig up the name again.
Anyways they are yours if you want them.
EDIT- I got them from the manufacturer FSI they have an office in Calgary.
FSI International
I think they were only a couple bucks each.
