That filter was just a piece of open celled foam,you ought to be able to
find something similar.Too restrictive a filter and your airflow will
suffer and the scope will overheat.

Here in europe, cell foam filter for the kitchen exhaust or for
stationary air condition system can be bought in the supermarkets. Or l
look for shops with kitchen/household goods. I cut the size I need to
fit in the rear of the 465/475/485 scopes, and this works well. Air
flow is not suffering much.
